From 1994 to 1996, the resistant and heavy-heading soybean varieties (lines) were screened in humid and semi-humid areas in eastern part of Heilongjiang Province, western arid and arid regions, northern arid area, central and southern black soil areas, Agronomic Measures and Effective Formulation Experimental Research. Through three experiments in five ecotopes in the past three years, a batch of cultivars suitable for growing and tolerant heavy-stubble soybean cropping diseases and insect pests in the areas with high yield and good yield were selected, such as Nenfeng 1 5, Xianfeng 1, Hefeng 35 and black Agriculture 39, Heilongjiao 92 -1 544 and Suining 10, Heinong 35 and so on. Applying the mitigating agent to the potash fertilizer, increasing the organic fertilizer, breaking the ridge clip fertilizer and subsoiling, various seed coating agents and soybean synergist, the soybean special agent can effectively control the loss of heavy cropping soybean yield
