摘要
文章重点总结了覆盖作物在改善土壤物理性质、减少侵蚀、提供"绿肥"效应、减少硝酸盐淋洗、增加有机碳储量、抑制杂草、改善土壤微生态、防治病虫害、影响土壤温湿度等方面的研究进展,并归纳了覆盖作物的应用困境。为根据不同的气候条件、土壤类型、应用需求等,合理选择覆盖作物、提高管理方式及后续研究奠定基础。
Cover crops owns plenty of underlying advantages.This paper mainly summarized the improvement of soil physicochemical property, mitigation of soil erosion, green manure effect, reducing nitrate leaching, increasing organic carbon storage, controlling weeds, improving soil micro-ecosystem, insect pests’ prevention, modifying soil temperature, etc.and thereby emphasized the how to apply the cover crops.According to the specific weather, soil and demands, the conclusions would provide a basis for choosing appropriate cover crops, and further work out the scientific field management.
