Guangyun existing doudan's artificial culture technology has applied for a patent, patent name: doudan high-yield farming method, patent number: 2008101682159, the technology uses greenhouses and other heating facilities, to realize the doudan's early listing, fill the market gap, creating a 300 yuan per catty doudan's myth. However, the existing technology in terms of disease prevention and control on the existence of more serious defects, to the bean Dan breeding to bring a certain risk, but also limits the promotion of breeding area. At the beginning of the year when the training course was held, there were more than 20 farmers 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. And on this basis, through the control of the three key steps, eliminating the pupae, moths and eggs with viruses and pathogenic bacteria, we realized the goal of hatching out physically healthy doudan larvae, and solved the disease problem completely. 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 the disinfection of soil, selection of soybean varieties, optimization of planting density, and control of soybean diseases and pests. The optimization of soybean Dan varieties and the development of alternative feeds and artificial feeds is the next goal of technical research.
