[Effects of Microbial Inoculants and Sheep Manure on Soil and Bacterial Diversity in a Degraded Alpine Meadow].
摘要
<0.05）. The first and second axes reached 55.37% and 2.47%， respectively， in explaining the variations in soil bacterial community structure， plant community characteristics， and soil physical and chemical characteristics. SEC was identified as the key factor driving rhizosphere bacterial communities in the degraded alpine meadow. ⑥ According to the function prediction results， the bacterial communities had obvious advantages in aerobic heterotrophic and chemoheterotrophic functions. Thus， bacterial fertilizer in combination with sheep manure improved soil fertility and soil bacterial diversity， with the Y2K1 treatment being the most effective. Namely， a dosage of 3 000 kg sheep manure in combination with 250 kg bacterial fertilizer per hectare achieved the best restoration outcome.
