不同土壤改良方法对草莓连作土壤理化性状、养分和微生物量的影响
Effects of Soil Characteristics,Nutrients and Microorganisms with Different Methods of Soil Improvement on Strawberry Continuous Cropping Soil
摘要
Abstract
The objectives of this study are to explore the causes and influencing factors of continuous cropping obstacles in strawberry plan-tation in Suyu District of Suqian City.We compared the effects of four soil improvement methods,i.e.,high temperature with closed shed,rice bran teturning,mixed microbial bacteria compounds,and Weibaimu pesticide on releasing continuous cropping obstacles in strawberry plantation.The results indicated that soil samples were collected and water-soluble salts,nutrients,enzyme activity and microbial biomass were measured and analyzed for the continues strawberry cropping(control)and the four treatments.Among the four treatments,rice bran(T2)was the most effective treatment to eliminate the salinization caused by soil anions;mixed microbial bacteria compounds(T3)treatment decreased soil pH,and showed the most significant effects in increasing soil available phosphorus content,and soil sucrase and catalase ac-tivities;Weibaimu pesticide(T4)treatment showed the most significant effect in reducing the contents of K+,Ca2+,Mg2+in soil,increasing soil pH and the content of Na+,organic matter and available nitrogen,but in reducing the activities of soil sucrase,urease,catalase and per-oxidase.Different treatments showed significant distinct effects on improving soil quality during strawberry plantation,thus,we suggest to use specific method or combined methods to improve soil quality after considering all physical,chemical and biological factors that causing continuous cropping obstacles.Our findings provide an economical and efficient strategy to release continuous cropping obsstacles and im-prove soil quality during strawberry continuous cropping plantation.关键词
