| 摘 要： | 土壤是联系地上和地下生态系统的纽带,土壤微生物在土壤养分循环和作物吸收中起关键作用,被称为土壤质量的指标。土壤微生物通过分解土壤有机物,促进养分循环利用,并调控植物生长发育,随着现代农业种植结构的变化,特别是种植制度的改变,地上植物种类和生长状况常常影响土壤中微生物的群落结构和多样性,调控着作物生长发育,农田有害生物的发生,而影响农作物生产。综述了现代农业中几种主要种植模式,如轮作、连作和覆盖等对土壤微生物群落结构及与农作物有害生物的影响,强调科学合理选择种植模式的重要性,最后,讨论了这些种植模式有待深入研究的一些关键问题。

| Abstract: | Soil connects the above-ground and underground ecosystems. Soil microorganisms play a key role in soil nutrient cycling and crop nutrient absorption from soil, which are considered as indicators of soil quality. Soil microorganisms can promote nutrient recycling and regulate plant growth and development by decomposing soil organic matter. With the variation of cropping structure in modern agriculture, especially in application of some planting patterns, adversity crop species on the above ground often affect the structure and diversity of soil microorganisms’ community, which further promote/retard crop growth and development, and have an impact on the occurrence of crop pests and crop production. In this paper, we reviewed the relationship among main planting patterns of crops in modern agriculture, soil environment and pest occurrence in farmland, highlighted the importance of scientific and reasonable selection of planting patterns, and discussed some key problems for further study of these planting patterns in agriculture practice. |
