摘要: Major cropping systems and management practices can significantly affect soil nutrient content and bacterial diversity and relative abundance in soil. Microbial flora is an important driving factor in nutrient cycling, which may affect soil fertility, plant productivity and environmental sustainability. This experiment included the effects of different tillage methods of soybean cultivation on soil fertility and bacterial community. The differences of microbial diversity and relative abundance of soil bacteria under different planting management systems were analyzed by using amplification sequencing technology, and the regulatory factors affecting soil bacterial community structure were explored.This study found that the relative abundance of Proteobacteria was significantly positively correlated with the content of available P and Cu in the soil.. The relative abundance of Bacteroidetes is correlated with effective P, Cu, PH, Mn in soil, Actinobacteriaactinomycetes was negatively correlated with available OM,P and DTPA Mn, Acidobacteria was positively correlated with OM and negatively correlated with P, Cu. The contents of DTPA Cu, Fe and Mn in soil are most related to the structure and species diversity of bacteria in soil. Compared with soybean system, the system of soil fallow and crop rotation can better balance soil fertility and increase the stability of soil micro-ecosystem, which is of great significance for maintaining the sustainable development of soil productivity.
