农村实行生产责任制后,地块小而分散,很少用拖拉机深耕,同时,又不能合理倒茬,结果造成菟丝子的猖獗。据调查,去年大豆遭受菟丝子危害普遍,趋向严重,一般减产10～30%,玉米、大豆间作的地块也发生很严重。造成危害严重的原因,主要是未能及时发现,即使发规了也没有很好防治。为此,撰写此稿,供生产上参考。 After the implementation of the production responsibility system in the rural areas, the plots are small and scattered, seldom cultivated by tractors, and at the same time they can not be rationally stubbled. As a result, the dodder is rampant. According to the survey, last year, soybeans suffered a general threat of dodder, tend to be serious, the general cut 10 to 30%, corn, soybeans between plots also occurred very serious. The causes of serious harm, mainly failed to find out, even if the rules have not been well controlled. To this end, writing this draft for production reference.
