施肥对农田线虫群落特征影响的研究进展

Research Progress on the Effects of Fertilization on the Characteristics of Nematode Communities in Farmland

施肥可以改变土壤肥力和微生物特性,从而间接改变土壤线虫的群落特征,不同的施肥方式可以提高食细菌线虫的数量,减少植食性线虫的数量,优化土壤线虫群落结构。线虫可以作为土壤健康和土壤环境变化的指示器。本文归纳了学者在农田生态系统中对线虫群落特征的研究进展,综合分析了不同施肥方式对线虫群落特征的影响,并针对肥料在线虫防治中的应用进行展望。

Fertilization can change the community characteristics and soil fertility of soil nematodes.Different fertilization methods can increase the number of bacteriophagous nematodes,reduce the number of phytophagous nematodes,and optimize the community structure of soil nematodes.Nematodes can be used as indicators of soil health and changes in soil environment.This paper analyzed the impact of different fertilization treatments on nematode community characteristics,and prospects were put forward for the improvement of fertilization methods in future farmland.
