摘　　要：通过生长调节剂、施用化肥、应用杀虫剂、杀菌剂等化学措施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 result showed that: when the environment of root and its border was improved by using chemical method, the growth of roots 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.
