After each harvest, the amount of sweet potato string in the field in Vinh Long is very large, about 100,000 tons. Photo: Minh Dam. Vinh Long Agricultural Extension Center has successfully tested the method of producing straw mushrooms from sweet potato vine. This is one of the new ways to diversify the source of materials for growing straw mushrooms, potentially replacing rice straw. According to the Department of Agriculture and Rural Development of Vinh Long province, Binh Tan district has an annual sweet potato production area of ​​14,000 hectares. After harvesting the tubers, the amount of sweet potato wire in the field is very large, about over 100,000 tons/crop. This amount of by-products is not properly treated, which can easily pollute the environment. The beaten sweet potato string is rich in nutrients and has been studied for silage as animal feed. However, the amount used for this purpose is not much, so the remaining source of by-products is still large and has the potential to be used to grow straw mushrooms if treated appropriately. Ms. Truong Thi My Loc, Head of the Research Project on growing straw mushrooms from sweet potato vine (Vinh Long Agricultural Extension Center) said: The project committee conducted a study on the production of straw mushrooms (Volvariella volvacea) from ropes. sweet potato in Binh Tan district. The objective of the study is to study and initially test the basic method of processing sweet potato vine into a suitable substrate for the production of straw mushrooms. Since then, the study has found the most suitable substrate mixing ratio to initially propose the process of producing straw mushrooms from sweet potato vine for the best yield and quality, improving product value, contributing to achieve the goal of restructuring the agricultural sector. Research shows that during the dry season, especially the spring-summer crop, with continuous hot and sunny conditions, sweet potato strings are treated and dried for 10-15 days to reach a moisture balance of 13-15%, suitable for substrate for mushroom cultivation. Using sweet potato wire to grow straw mushrooms brings many practical effects. Photo: Huu Duc. The use of sweet potato wire to grow straw mushrooms is more effective than growing from straw when people can take advantage of the area in their potato fields to process (dry the wire), incubate the wire and grow the fungus, bringing effective results. high economic. This is suitable for households who cultivate rotation according to the structure of rice – sweet potato or sweet potato – other vegetables, both creating favorable conditions to take advantage of the source of sweet potato cords and rotating crops to cut off the source of pests and diseases in the crop. land. In addition, using sweet potato by-products to produce straw mushrooms brings many benefits such as significantly reducing soil and water pollution and protecting human health. In particular, this method also takes advantage of organic fertilizers, contributing to increasing income for farmers. At the same time, the research topic also contributes to diversifying the source of raw materials for mushroom cultivation, opening up new directions and new ways for farmers to take advantage of the abundant and stable source of sweet potato by-products to grow. develop the cultivation of straw mushrooms. According to Ms. Truong Thi My Loc, currently, the research team is continuing to perfect the research process to transfer techniques to organizations and individuals in need.

Besides, there were many other notable outbreaks such as the one at Hoc Mon mechanical workshop (51 cases), Ehome 3 apartment building (59 cases), Kim Minh Company (27 cases), Tan Phu District Hospital. (13 cases) Regarding the Hoc Mon mechanical workshop, an employee at the garment factory in Vinh Loc A industrial park (Binh Chanh district) was taken to concentrated isolation from June 9, and tested positive on June 15. Also located in Vinh Loc A industrial zone, on June 12, through a screening test at the hospital, a worker working at a food company was also positive. From here, the health sector took more than 100 test samples of F1 and screened for about 500 employees at the dormitory of this facility, and 350 people at the factory, and found 11 positive aggregate samples. Cu Chi field hospital, where COVID-19 patients are treated in Ho Chi Minh City. Photo: HOANG LAN On June 13, through screening, Xuyen A Hospital discovered a positive person in Tan Phu Trung industrial zone (Cu Chi district). Continue to screen close contacts, family members, recorded 4 positive cases and 6 positive pool samples. In addition, through community screening, testing more than 1,500 workers staying in Binh Tan district working for PouYuen company, there were 2 positive cases. Binh said that in the coming time, the medical force will continue to strengthen measures to control the COVID-19 epidemic in the area, strengthen tracing investigation, thoroughly zoning out the epidemic, and testing on a large scale. high-risk areas to look for sources of infection. The authorities will tighten the streamlining and screening of patients who come for examination and treatment, especially paying attention to checking epidemiological factors, carefully screening people coming from such as places where COVID-19 cases have been recorded. , who have suspicious symptoms.

Every nearly 4:30 pm, Mr. Phuoc pushes his bread cart to the markets and garment companies near his home to prepare to welcome the first guests. Bread of all kinds of shapes of Mr. Phuoc attracts the curiosity of the people around. Thanks to a predestined business relationship, he was bought by many young people for support, and from 7pm he was out of bread.

The difficulty of making animal bread Taking advantage of the space in front of the ground floor, Mr. Phuoc opened a small bakery. There are no eye-catching advertising signs, inside only an oven and a few baking tools. As a small business, everything from preparation to sales is done by him. After mixing, the owner rolls the dough into even pieces to shape. From the fine round dough, Mr. Phuoc skillfully molded it into many different shapes. “The shaping stage is the longest. At this time, the worker needs to be patient, careful, with many details, it is difficult to invest time in practice. Usually, I squeeze a baby about 7-8 minutes, ”the 37-year-old owner chatted with reporters while meticulously adjusting the cake. Beautiful bread rolls are baked after many different stages. Mr. Phuoc can shape more than 10 animal models such as dragons, spiders, turtles, crabs … However, he only chooses his favorite models for sale. Each one has its own unique features, but the best-selling models are still crocodiles and horses. These are also the two most difficult pictures to do because they have to cut and graft the dough, it takes more effort. When forming, the dough is incubated for one more hour. It takes almost 2 hours from the first step to the finished product and then 15 minutes of baking on high heat. “With baking, baking time is the most thrilling. Because I thought it was beautiful when I did it, but it didn’t look like I wanted it, it took time to correct it, ”added Mr. Phuoc. With animal-shaped bread, the cake will have a soft intestine when it is finished, but other parts such as the legs and beard are always more crispy or easy to be hard if baked over heat.

Animal-shaped sandwiches received a lot of attention when he joined the show Challenging comedians season 3 (2016). In his skit, Mr. Phuoc impressed two judges Truong Giang and Tran Thanh with the charming and friendly style of selling bread. “That was the first time I brought animal bread on stage. After the show, my bread was known by many people. One day there were people selling them to the market, they asked for a photo together. Although there are no awards at all, it is also the most memorable memory since entering the profession “, Mr. Phuoc shared. His bread is loved by both children and adults. Minh Thu (23 years old, Binh Tan district) often stops to buy bread from Mr. Phuoc on his way home from work. Two of Thu’s most favorite patterns are the crocodile and the turtle image. Thu said that the intestine of the cake was already soft and fragrant, so just dipping it with a little condensed milk was delicious. “Every afternoon I see the owner selling here. Sometimes when we come out late, we run out of cake. People buy a lot, especially around 5am, ”said Thu.
