摘要
通过对甘肃环县典型草原试验区中不同载畜量下草地土壤微生物数量的季节动态变化的研究,表明在退化草地中采取围栏封育或适度的放牧,可以提高土壤肥力和微生物的数量,对退化草地的恢复演替有良好的促进作用。
The dynamic quantitive characteristics of soil microorganism in typical grassland under different carrying capacities in Huan Courty of Gausu Provirce were studied and the results showed that the number of soil microorganism was increased and the soil fertility was improved while the degraded grassland was enclosed or under moderate carrying capacity.
