Study on phosphorus fertilizer reduction of winter wheat in Xinjiang based on soil physical and chemical properties and microbial community optimization

Excessive application of phosphate fertilizer is a common problem in winter wheat area of saline-alkali land in Xinjiang, which not only affects soil physical and chemical properties and soil microbial community, but also leads to the decrease of wheat yield. In order to solve this problem, we studied the effects of different gradients of phosphorus fertilizer reduction on soil physical and chemical properties, soil microbial community and final wheat yield.
