摘      要：In recent years,the abuse of chemical fertilizers has caused numerous environmental problems,such as soil acidification and *** chemical fertilizers with organic fertilizers can effectively alleviate these ***,the effects of alternative organic fertilizers remain *** explore the effects of organic fertilizer substitution on rice yield and paddy soil physicochemical properties and bacterial community structure,we conducted a 5-year experiment using different proportions of organic fertilizer substitution in a double-cropping rice field in Jiangxi,*** results showed that replacing chemical fertilizers with organic fertilizers can reduce soil acidification,increase soil organic matter content,nutrient contents,and enzyme activities,improve soil physicochemical properties and microbial community,and enhance soil *** organic substitution also had positive effects on rice *** findings enhance our understanding of the effects of different alternative organic fertilization methods and have important theoretical significance for the promotion of the use of organic fertilizers in the future.
