摘　　要：本文对大豆连作条件下土壤多糖的含量，土壤多糖与土壤酶、基础肥力、微生物数量的关系进行了探讨。大豆连作使土壤多糖含量降低，多糖与蔗糖酶、微生物数量及基础肥力是显著正相关。这说明大豆连作不适宜土壤多糖的积累及转化，从而降低了土壤肥力影响了大豆产量。In this thesie we analyzed the relationship about the content of soil polysaccharides with soil enzyme and soil fertility as well as rhizosphere microbe. The experment result show thatreducation of content of soul polysaccharides was due to soybean continues-cropping. There wassignificant positive correlation between sacchurase and rhzosphere microbe as well as soil fertility. The results show that continues-cropping of soybean was not suitable for accumulation and inversion of soil polysaccharieds. This induces reduction of soil fertility and affects soybean yield.
