摘要
文章概述了覆盖耕作、少耕、免耕和轮耕轮作对土壤微生物的影响。认为采用保护性耕作技术配套合适的施肥除草制度,可以使土壤微生物数量、活性等保持较高水平,并能创造良好的生态环境,达到高产、高效、低耗、保护环境及保证农业可持续发展的目的。
The effects of mulch tillage, minimum tillage, no-tillage and crop rotation on soil microorganism were summarized. The study results indicated that applying conservation tillage combined with appropriate fertilizing and weeding system, the quantity and activity of soil microorganism could keep a higher level, the entironment could be better and the purposes of high yield, high efficiency, low cost, environmental protecting and agricultural sustainable development could be achieved .
