One of the steps to graft the branches to renovate citrus varieties. Photo: H.Tien. Steps taken before transplanting – On the garden of sour grapefruit varieties or low quality indigenous grapefruit varieties (real grapefruit): Choose plants that are 3-7 years old, grow well, be free of pests and diseases, especially have no stem borers, no germs. leaf rot yellow leaf disease, greening leaf yellowing (Greening) and Tristera’s disease. Then, cut down the entire canopy to the stem or branch with a diameter of ≥ 2cm, leaving only the ends for eye grafting in the position of the stem with the color of the cake, the same size as the top of the chopsticks. The number of branches left for grafting should be arranged evenly 0.5 m on the tree canopy as a mesh. Grafting season can be carried out all year round. It is best to graft in 2-3 months and 9-10 months. Note, stop watering and fertilizing on real plants 15-17 days before grafting; do not extract and graft trees into the rain. – On the mother Ruby grapefruit tree, choose a tree that grows balanced and free from pests and diseases as above. It is advisable to choose mother plants grown in a net house to prevent insects, to avoid completely dangerous diseases such as Greening and Tristera. Then, select branches under 1 year old, have rounded stems and are tilted from horizontal canopy upwards, then remove all leaves, leaf stalks attached and remove the tip at the position of the stem color of the cake. Continue to cut the branches to divide the seedling into branches containing 4-5 leaf axils, 7-10 cm long and have a flat color. Technique of grafting the branches (also called grafting, grafting wedge) – At the base of the seedling segment, use a specialized knife to cut 2 opposite beveled slices, 2-2.5 cm long to remove 2 stem parts at the base of the seedling and open a wedge-shaped composite end. At the predetermined graft head on the phylogenetic tree, split a line 2.5 cm deep at 1/3 of the tip diameter to open a grafting mouth, insert the wedge-shaped graft head into the grafted mouth that just opened above. Ruby grapefruit has been successfully grown in our country. Photo: TL. Then, stretching and twisting the nylon strip, twisting the rope, then wrap 5-6 rounds tightly around the graft. Finally, pull the grafted plastic strip flat, completely covering the seedlings and grafting spots, so that rain cannot penetrate the grafting marks and keep the seedlings from dehydrating. After about 10-15 days (depending on the season), the grafted eye will sprout. Must eradicate in time the sour grapefruit sprouts growing outside the grafted eye. Note choosing self-destructing polypropylene tape. – In addition to improving the seed by grafting wedge into the branches mentioned above, it is also possible to graft wedge into the cross section of the branches of much larger size, or graft windows, small wooden eyes along the trunks. tree, trunk. However, these grafting methods have certain limitations, compared to the method we introduced in the previous section, such as, small eye grafting with wood, only taking the seed eyes open, the tree will grow long. , time for exploiting business results is slower … Take care of real plants after grafting Spraying to draw amulets when the eyes are like sprouting is 0.5-1.0 cm long. Except for red spiders, soft aphids, leaf hoppers and plant diseases, during the period when eyes are like spreading branches and canopy. Fertilizer for 1 root: 0.2-0.3 kg NPK 13-13-13 + TE, fertilize periodically once a month. Foliar fertilizer sprayed evenly 7 days / times. Decomposed chicken manure 20-30 kg + 2-3 kg of microbiological organic fertilizer, fertilizing when the grafted eye has reached about 15 cm long branches. After 1-2 years grafting and improving, Ruby grapefruit trees have been exploited for business. From this stage on, the steps to take care and control pests and diseases are similar to other current pomelo seedlings. Ruby grapefruit is one of the elite citrus varieties of Thailand, which has been imported into our country. The variety has the advantages of strong growth and development, beautiful fruit shape, good resistance to pests and diseases, red fruit, thick and thick pods, fragrant sweetness, no seeds … Grapefruit is equivalent to or slightly better than that of our country’s green skin grapefruit. , depending on farming techniques and ecological conditions. Ruby grapefruit tree is easy to distinguish from other grapefruit varieties thanks to the small leaves and branches, smooth hair.

Khan’s farm is located in Malihabad, a mango paradise in northern India with more than 10,000 hectares. Amir Khusro, the Indian-Persian poet, has called mango, native to India and tropical, subtropical climate, as “the most beautiful fruit of Hindus”. The cultivation of mangoes in India began many centuries ago during the Mughal Empire. This country is also the largest mango producer in the world, with more than 1,000 varieties and accounting for more than 40% of production. Mr. Khan and the mango season were good last year. The story of “mango trees 300 kinds of fruits” With the help of his son, Khan has grown mangos on 22 acres of farmland, a property cultivated by his grandfather since the 1900s. When Khan dropped out of high school and started his life, his family planted only a few local varieties, similar to nearby mango farms. Khan’s dream of grafting mangoes rekindled at the age of 15, when he saw a rose-hybrid tree in a friend’s garden. The flower tree had flowers of different colors that made him wonder if a single tree could produce such fruits. “Naturally I want to propagate the mango tree like what I saw on that rose bush,” he said. The 300-fruit mango tree is inspired by a hybrid rose bush. At the age of 17, Mr. Khan successfully grafted 7 varieties of mango into one tree. After the flood killed the tree, he determined to learn more about grafting in the family orchard. Over the years, Khan has been steadily improving his art of grafting. In 1987, he started grafting different varieties onto a 100-year-old mango tree. These mango varieties were collected by him from all over the country, including rare varieties. Mr. Khan said that the tree currently has more than 300 types of mangoes and he calls it Al Muquaraar. “Miracle Mango Tree” has a wide canopy, large enough to accommodate 15 people sitting under it. The branches are heavy with fruit with leaves of different colors such as gray green or olive green … The mango fruit on each branch also has its own shape: round or oval, some green, yellow, others have orange, pink and purple. The variety of each type is identified by a small label on the stalk: Dasheri mango from a nearby village, Himsagar from West Bengal, Langra from Bihar or prized Alphonso mango, sweet, saffron-colored mango in demand. high domestically and internationally. Mr. Khan’s three famous mango varieties are Tommy Atkins, Suvarnarekha, and Husn-e-Ara. “This miraculous mango tree is not just a tree, but an orchard, a universe,” said Khan. Free fruit donation, breed new breeds When asked how to protect trees from birds and insects, Mr. Khan said: “I don’t drive them away. The well-being of nature is for all to share.” During the harvest season, Khan and his son pack farm produce for sale and export. They give free fruit of “miracle tree” to visitors to the garden. “Like two kids from the same parents but different in looks and personality, mangoes sprouting from the same seed can also be completely different,” Khan said of each mango, as if it were kids. In addition to grafting, Mr. Khan also bred new varieties of mango, experimented with flavor and texture and gave them creative names. He named his new mango variety after Prime Minister Narendra Modi (Namo Aam) and Bollywood actor Aishwarya Rai. Khan said: “I created a mango after the famous cricketer Sachin Tendulkar. He called to thank him and expressed his happiness.” Most recently, he named two new mangoes “doctor aam” and “police aam” to thank the work of the rescue pioneers during the pandemic. Many famous people visited Mr. Khan’s farm. Mr. Khan won many awards, including the Padma Shri, one of India’s highest civilian awards, and recorded in the Limca record book. He visited Dubai and Iran to teach the art of grafting. In 1999, he created a mango tree with more than 54 varieties for the Mughal garden inside Rastrapathi Bhavan, the official residence of the President of India. “Mango grafting is just an art and has no commercial value,” said DK Sharma, vice president of the Mango Growers Association of India. Mr. Khan disagrees, saying that grafting is very common in commercial fruit and nut production. He considers it an art of practical value.

That is because the farmer owns a grafted mango tree to create 300 different types of mango per tree.

Mr. Kalimullah Khan has been passionate about grafting mangoes on the same tree since he was 17 years old.

The man with a skillful hand is called Kalimullah Khan, 80 years old, also nicknamed “the mango man”.

The mango varieties he grafted onto trees were brought from a nearby village or from other locations across India.

Currently, India is the largest mango producer in the world with 40% of global production and the country has up to 1000 different varieties of mango.

The special thing is that Kalimullah Khan has not finished high school and has cultivated on the agricultural land left by his grandfather with the support of his son.

Mango tree with 300 different fruits impresses many people when coming here.

At the age of 15, Mr. Khan was delighted to see hybrid roses planted in a friend’s garden.

On a persimmon tree there are flowers of different colors that motivates him to think of a unique mango tree with many fruits. At the age of 17, Mr. Khan grafted 7 different types of mango on the same tree. Unfortunately, flash floods caused this tree to be damaged, but this old man still retains his passion.

Today, he personally creates many different varieties of mango and is known by everyone.

In 1987, Kalimullah Khan started grafting different types of mango onto a 100-year-old mango tree. In addition to grafting, he also created new varieties of mango and named after famous people in the fields …

Currently, he has a farm located in a belt specializing in growing mango up to 10,000 hectares of India. During the harvest season, he and his son pick mangoes and put them in barrels for sale, export or give them free of charge to visitors.

Many famous people visited Mr. Khan’s farm. This old man also won many awards including Padma Shri – the noble award in India.

He also went to Dubai and Iran to teach grafting, in 1999 he created 54 different varieties of mango trees for Mughal gardens in the presidential mansion of India.
