| 摘 要： | 通过设置在甘肃省定西市安定区李家堡乡的田间定位试验,研究了不同耕作方式下（NTS、TS、NT、T）土壤微生物生理类群数量和酶活性及其相关性。结果表明：与传统耕作（T）相比,保护性耕作方式（NTS、TS、NT）能显著增加土壤微生物生理类群数量,增强酶活性。不同的保护性耕作方式下,土壤微生物生理类群数量和酶活性存在显著差异...

| Abstract: | Based on different tillages experiment in Dingxi,the effects of soil microbial physiologies colony,soil enzyma activities and their relationship under different conversation tillage measures(no-tillage and straw cover,plough with straw incorporated,no-till without straw,conventional cultivation and no straw) were studied.The results showed that comparing with conventional cultivation,soil microbial physiologies colony numbers and enzyma activities increased significantly under conversation tillages,but the ... |
