加强不同农作物专业化和集中化种植 ,全面要求科学依据的轮作结构和大豆轮作饱和度 ,推广到生产上可获得稳定的产量和经济效益 ,并达到植物卫生部门的认可。1981- 1984年在全俄大豆所耕作研究室的轮作试验中 ,研究了大豆根腐病的发育动态、连作和不同大豆轮作饱和度及前作的影 We will intensify the specialization and centralized planting of different crops, fully demand the scientific basis of the rotation structure and the saturation of soybean rotation, and promote the production and economic benefits to the production and achieve the approval of the plant health department. In 1981-1984, in the rotation test of all soybean research labs in the whole of Russia, the developmental dynamics of soybean root rot were studied. The effects of continuous cropping and the saturation of different soybean rotations
