Improvement Effect of Compound Microbial Fertilizer on Soil in Red Soil Degradation Area
Aiming at the current situation of low fertility and weak capacity of water storage and fertility retention in the red soil degradation area,by the application of compound microbial fertilizer developed by the project team,it was discussed the conditioning effect on improving the physical,chemical,and biological characteristics of red soil in bare soil areas.The results show that,application of the compound microbial fertilizer may effectively improves the physical characteristics of soil,reduces the problem of soil acidification,significantly improves the contents of organic matter,effective phosphorus,effective potassium and effective boron,accelerate the reproduction of Haliangium of plant life-promoting bacteria and cellulose-degrading bacteria,while inhibits the growth of bacteria causing nitrogen loss,so as to improve the utilization rate of fertilizer.Therefore,the compound microbial fertilizer can be promoted as a new product to control soil erosion in red soil degradation areas.
