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.

Key words: crop, planting patterns, soil microorganisms, continuous cropping mode, crop rotation mode, mulching mode, pest
