Mr. Negi has personally turned the barren land in the cold desert of Himachal Pradesh into a green oasis. (Source: YouTube) In 1977, the Government of India began an ambitious program to reduce the negative effects of desertification in the hot and cold deserts of this Asian country. Mr. Anand Dhawaj Negi was working in the finance department in charge of the Desert Development Program at the time and had seen millions of dollars spent with no real results. Whenever he asked the scientists and program officials about the results, the answer was always that they lacked the technology to grow any sustainable crops in harsh environments. desert . The son of a farmer himself, Negi was tired of excuses and took a leave of absence in 1999 to fix the problem himself. In 2003, he decided to quit his job to focus all of his energy on his growing desert oasis. Mr. Negi has personally turned the barren land in the cold desert of Himachal Pradesh into a green oasis just for everyone, especially the farmer struggling in the region, seeing desert reclamation as entirely possible. It was not an easy thing to do, but the former official knew what he had to do and had the ambition and patience to get through it. Mr. Negi’s first attempt failed as the seeds did not have enough water to grow. He overcame this first challenge by planting by contour, tilling the soil along a consistent height to capture rainwater and reduce soil erosion. At the same time he works with the local community to create irrigation canal The shallows channel runoff from glaciers about 25km away. After witnessing this process, the local irrigation department also began to cooperate. “The irrigation department supplies water to this area. Before that, water was not provided until before June. I connected to the Kuhls area and managed to get a water supply in April and May. When we did, the Irrigation Department also cooperated and ensured a regular water supply here,” Mr. Negi told Down to Earth. But water is just one of the challenges this frigid desert region poses. Sandy soil lacking nutrients is another problem. To provide enough nutrients for the crops he wanted to grow, Mr. Negi started a farm with about 300 Chigu goats and mixed their manure with earthworms to effectively double the nitrogen content of the soil. . This also helps the clover hectares he planted around the oasis to thrive. In the past, clover would fade away as new plants grew. It was the clover growing area that overcame the problem Mr. Negi had at first, a rodent attack. These species will come to eat the delicious plants, so the farmer must plant clover in the legume family around the more valuable crops. Because hares love clover, when there is an abundance of this plant, they don’t bother with other plants. Since starting his job in Himachal Pradesh, Mr. Negi has spent all his money experimenting with combining local farming techniques with more scientific farming methods. It’s a laborious process, but over time the tree mortality rate drops from about 85% to just 1%. After proving that valuable crops such as peas, potatoes, green beans, apples and apricots could be grown even in harsh desert environments, the former official began to focus on long-lasting greenery. years, as he considers them essential to combat climate change in the region. “My first priority here is reforestation. Fake acacia is the most planted. Then there are willows and wild apricots. As for fruit trees and other crops, including green beans, I planted them only as a model for people to replicate,” said Mr. Negi. With just the help of two volunteers, Mr. Anand Dhawaj Negi transformed a cold desert area of ​​more than 90 hectares into a green oasis, receiving praise from both locals and scientists. People come from far and wide to witness this real-life miracle, some buying Negi’s natural fertilizer to grow their own crops and others bringing their livestock to eat clover, the fodder for livestock. cattle are considered the best in the region. Mr. Anand Dhawaj Negi has turned a cold desert area of ​​more than 90 hectares into a green oasis. Sadly, Anand Dhawaj Negi, the desert healer, passed away last month at the age of 74 from a stroke. He will be remembered as a local hero and the green oasis project hopes to be preserved as a reminder that nothing is impossible. Negi’s family intends to continue his work, but has asked the government to take responsibility for the oasis and help the family in its conservation. Virender Sappa Negi, Mr. Negi’s wife, told The Better India news site: ‘Before he said goodbye to us, he planned to plant some evergreen or conifers such as pines and deciduous trees. We want to fulfill these last wishes of his. In addition, we want the state government to take responsibility for this oasis so that his work can inspire future generations.” Anand Dhawaj Negi has become one of the many Indian legends who devoted their lives to afforestation like Uttarakhan’s “Tree Man” or Aditya and Poonam Singh.

The first robot tractor in operation on the farm in the UK. Photo: TL. According to Fram Famers (UK), commercial robot tractors have been put into operation at Home Farm Nacton (member of Fram), in Suffolk (United Kingdom), from mid-April. Technological improvement required, along with difficulties in finding seasonal labor, led to the investment of robot tractors at the aforementioned farm. Home Farm, which specializes in organic agricultural production, received the Robotti 150D from Agrointelli, a Danish company. It was the first robot tractor to operate in the UK, and is now fully operational on the farm. The Robotti 150D is used to till the soil to prevent weeds from sprouting by using a harrow attachment. In the near future, Robotti 150D at Home Farm will be used to perform many other jobs such as mowing the lawn, punching holes to plant onions, etc. Home Farm produces both organic and conventional vegetables, including leeks, bok choy, onions, beets, potatoes, sugar beets and grains, on 1,940 hectares. The farm is looking to apply more advanced technology to production and business activities. Andrew Williams, Home Farm manager, said: “A large portion of our produce is organic, so we are increasingly limited in how we can control weeds. Organic production requires a lot of repetitive work as the beds are constantly plowed and weeded. Meanwhile, sourcing seasonal workers, mainly foreigners, has become increasingly difficult. We want to look to the future of farming and Robotti fits our setup perfectly.” Designed and manufactured by Agrointelli, the Robotti 150D is controlled automatically by GPS via an integrated computer, independent of the operator, instead following a pre-programmed route in the field. Tractor Robotti 150D. Source: Agrointelli. “Accuracy lies in the GPS mapped field, with Robotti always taking the exact same lines,” explains Frederik Rom, sales manager for Agrointelli. It is equipped with an RTK GPS, so setting up on any farm is simple. It takes about 10 minutes to map the 4-acre field at Home Farm and another 10 minutes to log the weeding plan into the system. It is important that this is correct from the start, as it will determine reliable performance.”

Mulberry skin – in the local language of Ha Tinh is elm skin. This is a woody fruit tree, appearing a lot in highland areas in mountainous districts such as Huong Son, Huong Khe. With the characteristic that the results are chained on the stem from the root to the top, the mulberry tree in the fruit season is very beautiful, chosen by many families to grow as an ornamental tree. Mulberry is usually ripe around June, lasts until July, August of the solar calendar… mid-May has begun to have ripe fruit. The young skinned berries are dark red or dark green, but when ripe, the skin turns ivory white, apricot yellow and has a sweet and sour taste. The mulberry tree trunks are filled with tens of thousands of fruits, making both growers and guests feel good. Mr. Tran Van Ky’s house (residing in Ha Linh commune, Huong Khe district) can grow 17 roots of mulberry skin, in the crop every day, traders come to ask to buy. These mulberry roots have been planted since 1980, each crop gives an income of tens of millions of dong. Each root averages from 1.5-2 quintals of fruit. The current selling price is from 25 to 30 thousand VND/kg, bought by small traders in the garden. As Mr. Ky shared, when the harvest is complete, he will weed, dig the soil and dig a deep hole near the base of the mulberry tree to fertilize. The characteristic of this plant is that it loves water, so this area is flooded every year, it is alluvial, so the tree grows well. No need for sophisticated care, on this occasion Mr. Ky’s family has harvested from 3 million VND or more each. The fruiting stem starts from the root to the tip. As Mr. Ky shared, there were many guests who came to pay more than tens of millions of dollars for a mulberry tree that is over 40 years old, but he still did not sell it. The mulberry tree stumps are decades old, not only economic in fruit collection, but also sought after by many people to buy. The berries are plump, ripe, waiting to be harvested. The fruit grows from the base to the top of the tree. Ms. Nguyen Thi Hoa (Ha Linh commune) also has a mulberry tree that is decades old at the time of fruit harvest. Ms. Hoa said that in previous years, this root yielded more than 2 quintals of fruit, but this year the harvest is more likely. “Strawberry has many different kinds of fruit, some trees give red fruit, but there are white fruit trees. On this occasion, people come to buy a lot, they will climb up to pick, then come down at the yard to weigh and charge. Like this original, someone came to pay tens of millions and did not sell. Because I want to keep it for my children and grandchildren, I have a few million silver coins here every year,” said Mrs. Hoa. On this occasion, Ms. Tran Thi Ha (resident of Huong Khe district) often goes to houses with skins to buy and sell. She said, usually traders will choose the sweetest, most delicious root to buy, the price is offered by the grower. “The strawberry skin is harvested in about 20 days, and customers buy a lot. Some people buy a whole weight and take it to Hanoi and Saigon to give it,” said Ms. Ha. The berries are picked and put on the street for sale.

Note that the reduction is gradual and should not be fasted). Gradually reduce the amount of rice and food in each meal. Drink 1-2 cups of water before each meal, this helps to increase the effect weight loss up to 30% compared to not drinking. If you maintain this habit, the ability to keep a stable weight will be very good. Eat slowly and chew thoroughly It usually takes 15-20 minutes for you to “feel full” after you start eating. Therefore, if you eat fast, you will “load” more than if you eat slowly. The method of eating slowly, chewing thoroughly is considered quite effective in helping you eat less and control the amount of food you eat. In addition to eating slowly, chewing thoroughly, what kind of food you tolerate in your body has a huge impact on weight loss process your. Some foods can support your weight loss process more effectively, such as using vinegared black beans or eating apples on an empty stomach. Reduce food intake slowly, avoid evening snacks You should . For example, it is also 2 ladles of rice, but instead of being full, it will be 2 ladles empty or, after stirring, skim off some of the rice above and return it to the pot. With food, you can pick up a little bit and remember “whenever you take it, eat it all and then put something else in the bowl”. Choose a bowl that is small and has a blue color To “fool” themselves, people who want to lose weight can eat in small bowls. In addition, you should choose a blue bowl because research shows that blue causes loss of appetite compared to other colors.

Inside Canto’s cave. After being scolded and criticized by his parents, 14-year-old Canto started digging in his family’s garden after school. Finally, Canto invited a friend to use a pneumatic drill to create a 3m deep cave. Canto also reinforced the roof and walls of the cave with concrete and columns. The total cost of the project is only about 60 USD (nearly 1.4 million VND). “I have always loved building small huts. I live in the countryside and when I find discarded wood, I build a nice house,” Cantor said. Cantor in his cave. Cantor’s cave sometimes suffers from flooding and is often visited by insects, spiders and snails, but the amateur builder doesn’t mind. A social media post about the cave caught the attention of local officials. The authorities have sent inspectors to check, to ensure the safety of the cave. “My mother also came down and said it was smaller than the picture in the video,” Cantor said.

According to Mr. Cong, during more than 2 months of mining Chia, the actual amount of copper received back only stopped at 3 units. Currently, on the Huobi exchange, Chia is being valued at $820. This means that after 2 months and 3 billion of capital, he earned about 56 million VND. Fear of missing out on green Bitcoin The reason given by Mr. Cong is that although Chia saves electricity, it is difficult to compete with the super mines in China. Besides, the dramatic drop in the price of cryptocurrencies in the past week also increased the payback time of Chia mines. The hard drive is what determines the success or failure of Chia mining. “I invest a lot of money but I am quite vague about my income. The reason is that I fear that I will miss the opportunity to get rich like the way Bitcoin created 4 years ago. There were very few Bitcoin miners back then, I was one of the first. That’s why I have faith in Chia. But things don’t seem to be as I thought,” Cong said. According to Mr. Cong, his Chia mining system uses a 6TB HDD. Each of these hard drives costs 6.5 million VND. The number of hard drives in Mr. Cong’s mine is close to 300. Previously, the price of HDDs was only about 2-4 million VND. However, the wave of Chia mining has made the hard drive double in price. To cope with the huge write rates of Chia miners, many memory manufacturers have designed SSDs specifically for this purpose, like TeamGroup’s T-Create Expert model with a write limit of up to 12,000 TB. Amazon Web Services also recently opened a Chia mining service for the Chinese market. Hard drives increase in price, are in short supply but still have to buy more “In the game of chia mining, whoever has the most large capacity hard drives, that person has a higher chance of winning. And the winners at this point are the mining pools in China. They buy large quantities of hard drives at very high prices to gain an advantage in the market,” said Mr. Reply Zing , a representative of GearVN store confirmed the shortage of goods with large capacity drive models. However, this company’s customers, mainly individual users, have not been affected much. Hard drive prices have doubled since April because of the green Bitcoin craze. “GearVN’s customers are mainly end users and gamers, with a demand for hard drive capacity from 1 TB to 4 TB. In this segment, the price and supply are still stable,” a GearVN representative shared. This is also considered the biggest risk when participating in the “Green Bitcoin” market. According to experts, the difficulty of Chia mining is many times faster than Bitcoin. This means that mining systems must be invested with as many hard drives as possible. Previously, Bitcoin could be mined at individual scale because of the slow increase in difficulty. In the Chinese market, many traders have gathered thousands of hard drives to redistribute to Chia miners. According to ADATA, thanks to Chia, the number of SSDs sold by this company has increased 5 times in the past month. The shortage of goods makes many manufacturers of hard drives and SSDs prioritize serving the Chinese market. Order time in other markets is 2, 3 times longer. “In the past, every time a new order was placed, the waiting time was about 4-6 weeks. Now, the waiting time must increase to 8-10 weeks, high-capacity lines can sometimes be up to 13-15 weeks. Calculated, the standby time increased 2, 3 times, “said a representative of a distributor of the Seagate hard drive brand. Despite having an advantage in power consumption, Chia has a problem with mining materials, here is the hard drive. “I have to constantly buy hard drives while the price is getting more and more expensive. Without a hard drive, we wouldn’t have a place to store the strings of codes that can form a Chia,” said Cong. Uncertain future Chia was created by Bram Cohen, the “father” of the BitTorrent peer-to-peer file transfer protocol. The company behind this currency is Chia Network, backed by investor Naval Ravikant, some well-known companies such as Andreessen Horowitz or Cypherpunk Holdings. From May 3, this currency will be publicly traded and exchanged. According to the Business Insider , Split based on PoST (proof of space and time) consensus algorithm. In it, PoS (proof of space) describes an allocated hard drive space for blockchain block storage. In other words, the “miner” Chia will reserve a certain amount of memory space on the hard drive to store blockchains. Mining is very little, but participants have to constantly buy more hard drives in order to have space to store the blockchain. They will be awarded based on the ratio of memory cells that “miners” have to store compared to the entire network, as verified by a VDF server (aka Timelord). Chia Network, the representative company, said that this currency has good security, consumes less energy than coins using the PoW (proof of work) consensus algorithm. Unlike Bitcoin, Chia has no limit on the amount of coins mined on the blockchain. Instead, the number of diggers that can be mined will change continuously depending on demand. Chia Network, the company responsible for this currency will hold 21 million Chia in order to control price fluctuations, reducing the possibility of problems. Although the future of Chia is envisioned as ideal, the coin has only been traded on a number of crypto exchanges since early May with the token XCH. At first, the price per dong has more than doubled from $700 on May 4 to $1,600. However, facing the decline of the entire cryptocurrency market, Chia also suffered a price drop. Besides, too much hard drive also makes the Chia project away from the original “green” purpose of the founders. The owner of the net shop unplugs the machine, digs coins and waits for the translation to end Due to the impact of the Covid-19 epidemic, Mr. Nguyen Minh Quan (Thu Duc City) had to close the net shop, remove the graphics card to dig coins, earn extra income waiting for the reopening of the shop.

Oos Lions, hyenas and other predators still stalk the wildebeest, preventing them from eating too much of the plant. The variety of plants and grass supports other species, from fish birds to insects. In turn, these animals carry seeds or pollen throughout the plains, creating conditions for many types of plants to reproduce. Humans also appear there, but with relatively meager density. This is a prime example of an intact ecosystem: complex relationships that together maintain the rich diversity of the Earth. According to a survey of the ecosystems on Earth, most of the land on Earth – about 97% – no longer qualifies for ecological integrity. Researchers announced on April 15 in the journal Frontiers in Forest and Global Change: in the past 500 years, too many species have been either extinct or in decline. Specifically, scientists set the year 1500 AD, which means that only parts of the world are ecologically intact like 500 years ago with the addition of species of similar abundance. can be considered a wilderness. As a result, only 2.8% of planet Earth’s surface matches the description. These “wild plaques”, each with an area of ​​10,000 square kilometers or more, are scattered in various parts of the world. Of the few intact ecosystems, only about 11% of the land is in existing protected areas. These include Nouabale-Ndoki National Park in Congo, Serengeti-Ngorongoro in Tanzania, Alto Rio Negro indigenous territory in the Amazon forest, Great Siberian Polynya in northern Russia, and Kawésqar National Park in southern Chile. These are very rare and special places to be preserved, but only 11% of them are in protected areas. “Those are the best of the best, the last places on Earth have not lost a species as we know it,” said Oscar Venter, a conservation scientist at the University of North British Columbia. . It is important to identify such places, he said, especially for areas under development threats that need protection, such as the Amazon rainforest. Conservation scientists have long tried to map places that have not been affected by human activity. Researchers estimate that 20-40% of the Earth’s soil surface can be considered ecologically intact. But what can be detected by satellite is the ugly reality of the true extent of wildlife habitat. Beneath the seemingly intact tree canopy, the extinction of mammals and large birds from hunting, invasive species or disease has undermined the biodiversity of the areas. wild in the world. Biologist Andrew Plumptre, University of Cambridge said: “Hunting, impact of invasive species, climate change – these can harm ecosystems, but they are not easily detected. right through the satellite ”. Plumptre and his colleagues began looking for habitats that fully retain natural species, in abundance, in 1500 AD. That is the basis that the International Union for Conservation of Nature uses to evaluate the extinction of species, even though humans have changed their ecosystems by wiping out many large mammals over the past thousands of years. Overall, the amount of ecologically intact soil “is much lower than we expected,” said Plumptre. This shows how terribly man has affected nature. Some scientists question whether study authors are too strict in their definition of ecosystem integrity. Many ecosystems around the world have lost one or two species, but they remain vibrant, diverse communities. The decline of some species may not cause a catastrophe to the entire ecosystem, as other species may replace the role of lost species. The researchers calculated that while only 3% of the land is currently ecologically intact, bringing in up to five species lost could restore 20% of the land as before. This helps the ecosystem gradually return to balance.

1. How to plant roses with branches

1. Seasonality

Planting flowers by branches is actually the method of cuttings, and almost any time can be done. But the best time for cuttings falls between February and April and from August to October.

Illustration.

When cuttings in the rainy season are quite good, this will help less watering. As for cuttings in the dry season, water should be monitored regularly, always keep the soil moist, so that the new branches can take root and grow well. At the same time, when cuttings in the dry season, cuttings must be in a place with shade or must be made as a cover above.

1. Soil for cuttings

To cut rose branches, you should cut them in smoked rice husks, mixed with a little organic fertilizer such as decomposed cow manure or vermi-compost.

When dipping, it is necessary to cultivate the soil to relax and add more water to keep it moist. At cuttings, branches should be about 2 cm deep upright, not inclined.

1. Choose a variety of roses for cuttings

For the highest success rate, choose persistent persimmons such as wild persimmon, wild persimmon, but these varieties have not very beautiful flowers. The other types of persimmon, though not high in vitality, can still be cut.

In addition, there are persimmons that cannot be cut because the stem contains only a little starch, so the tree cannot afford to create new roots, so if cuttings will die.

1. Technique to choose cuttings

One of the important steps of growing roses with branches is choosing cuttings.

Choosing good cuttings is also an indispensable factor determining the success level of rose breeding. Ideally, you should choose the middle segments of the branches, roots or tops that are okay, choose those that are in the flowering stage, must be the twigs, not too old and not too young.

Branches used for propagation are straight branches, fresh and new within 1 year.

1. Cuttings techniques

After you have selected a healthy branch, about 20 cm long, use a knife or very sharp scissors to not crush the base of the branch, cut diagonally at an angle of 45 degrees. Cut away the dead flower buds, all the leaves and thorns from the lower part, and the upper part can be trimmed or left evenly.

Right after cutting, branches should be soaked in rooting stimulating solution and planted immediately to avoid bacteria penetration, killing rose branches.

1. Detail how to plant roses with branches

As mentioned above, planting roses by branches is the cuttings, which is a method of using a piece of the stem from the mother tree to be plugged into the ground, after a period of care, this stem will grow new roots and develop into a tree. new.

To cut the branches, dig a sufficient hole in the pot, loosen the soil and water it to keep it moist. Plug the rose branch to a depth of 1.5 – 2 cm, upright. Then, heap up the soil, squeeze the base so that the branches don’t wobble.

1.7 Fertilizer

After dipping, taking care of rose branches is not too difficult, just provide enough water, don’t let the soil get too wet to make the branches waterlogged.

When the branches start to produce leaves, some stimulants can be used to stimulate the plant to grow fast and bloom to large such as IAA or NAA, or some more popular substances such as Antonik or N3M, Super Roo.

2. Take care of roses

Location: Rose is a suitable plant to live in well-ventilated and sunny conditions. If there is enough sunlight for 8 hours a day, the tree will grow well and less harmful to pests, diseases, flowers and flower colors. also bright, beautiful, brilliant.

Watering: If you are planting in the garden ground you need to water 1 time a day, plant in a pot, water 2 times a day in the early morning and in the afternoon. Rose plants need enough water for the leaves to photosynthesize, if the plant is dry, it will appear red spiders harm the plant, yellow leaves and deciduous. You should limit watering at night because water will stay on the leaves, making the leaves more susceptible to fungal diseases.

Nutrition:

Nutrition: It is very important to decide whether or not your rose will produce lots of flowers, whether the flowers are large and vibrant or not, especially when you plant roses in pots. You observe the new branch if it has a dark purple color and a plump branch means that the tree is provided with enough nutrition, if the branch is thin and tall, it is necessary to add nutrients to the plant.

Land for planting: You should change your planted land once a year.

Fertilizer: Combine foliar fertilizer and root fertilizer alternately, once a month.

When the tree is at the top, the young leaves are supplemented with Dynamic seeds, bat manure around the base of the tree and watered to help the plant absorb nutrients well, mix NPK or agricultural DAP to water the leaves and stems.

When new plants sprout, flower buds add pink potassium, the flowers will have a strong characteristic color. But note that when the plants flower, do not fertilize because it will damage the flowers.
