Cultivation of bean Dan

Guanyun has applied for a patent for the existing artificial cultivation technology of Doudan. The patent name is: high-yield cultivation method of soybean single, and the patent number is: 2008101682159. This technology uses heating facilities such as greenhouses to realize the early listing of Doudan, fill the gap in the market, and create the myth that Doudan is 300 yuan per catty. However, the existing technology has serious defects in disease prevention and control, which brings certain risks to bean Dan culture and limits the promotion of culture area. When the training course was held at the beginning of the year, more than 20 farmers were present, with a breeding area of more than 400 mu. The second generation breeding technology has made a qualitative breakthrough in disease control and realized real indoor breeding. On this basis, through the control of three key steps, the pupae, moths and eggs with viruses and pathogenic bacteria were eliminated, which achieved the purpose of hatching healthy bean Dan larvae and completely solved the disease problem. Of course, the management of the breeding process is still very important. In addition, there is still a lot of work to be done in soil disinfection, soybean variety selection, planting density optimization, soybean pest control and so on. Optimizing the variety of Doudan and developing alternative feed and artificial feed are the goals of the next technical research.
