轮作模式下土壤微生物与线虫群落的互作研究现状

Research Status of Interaction Between Soil Microorganisms and Nematode Communities Under Rotation Mode

作物轮作种植在中国应用历史悠久,而针对不同地区不同栽培目的的轮作模式研究一直处于探索中。笔者以轮作在土壤生态学方面对土壤的改良作用着手,分析国内外学者关于多种轮作模式下土壤线虫与微生物群落的相关研究,讨论轮作模式下土壤理化性状对两者的影响以及在团聚体中微生物和线虫群落的关系。从宏观及微观空间尺度下分析两者在土壤生态系统食物网中的相互作用,根据其互作效应探究微生物、线虫对土壤环境的指示作用,以此来达到合理轮作、培肥土壤、作物可持续稳产高产的目的,使得农田土壤状况向着更有利于作物生长发育的方向发展。

Crop rotation has been used for a long time in China,and the research on crop rotation mode for different cultivation purposes in different regions has been in the process of exploration.Based on the role of rotation in soil ecological improvement,in this paper,the authors analyzed the research on soil nematodes and microbial communities under different rotation modes,discussed the effects of soil physical and chemical properties on them and the correlation of microbial and nematode communities in soil aggregates.The interaction between soil nematodes and microbial communities in the food web of soil ecosystem was analyzed from the macro and micro spatial scales,and the indicative effects of microorganisms and nematodes on soil environment were explored according to their interaction effects,so as to achieve the purpose of reasonable rotation,soil fertility improvement,sustainable and high yield of crops,and to improve farmland soil condition and promote crop growth and development.
