摘要

土壤微生物是土壤的重要组成部分

对土壤肥力的形成和植物营养的转化起着积极的作用

是土壤肥力和环境变化的重要指标。通过土壤微生物量测定

研究新银合欢植物篱对紫色土区坡地农耕地、经济林地2种土地利用方式及10°

15°坡度下0-20cm土层土壤微生物特性的影响。研究发现:新银合欢植物篱可以明显提高土壤中细菌、放线菌、真菌的数量及微生物量碳、氮含量;植物篱对经济林地小区土壤微生物数量

微生物量碳、氮的影响作用总体上大于对农耕地小区的

同时对10°农耕地的影响作用总体上大于对15°农耕地的;下坡的三大微生物数量

土壤微生物量碳

氮平均含量明显比上坡的多

下坡距离植物篱带最近采样点处三大微生物数量

土壤微生物量碳

氮含量明显比其他采样点的多。表明定植新银合欢植物篱有利于减少土壤肥力衰退

有利于土壤碳、氮素固持。
