摘　　要：通过生物措施以及综合调节根际微生态环境、促进根的生长、增强根的各种功能,可以减轻重迎茬种植的不利影响,提高重迎茬大豆的产量。The experiments had been carried out by 8 years in 9 rotation nurses with 9 plots and series of field experiments in 5 ecological regions of Heilongjiang province since 1993. In the same time, the investigation was made in soybean fields. The result showed that: When the environment of root and its border was improved by using biological method or synthetical method, the growth of root of soybean was advanced, and some functions of root were raised. So that, the yield of soybean, which was planted continuously or alternately, would be increased.
