摘要 植物-土壤-微生物共同构成根际微生态，其对植物健康和生长产生巨大影响。果树连作后根际微生态发生变化，影响果树栽培和果实品质。从果树连作障碍的成因出发，通过分析果树连作对微生物多样性的影响、土壤微生物多样性对果树连作的响应，总结出果树连作的解决措施，旨在为果树连作障碍修复提供帮助。

Abstract Plant-soil-microbe constitute rhizosphere micro-ecology which has great influence on plant health and growth. After continued planting， the changes of rhizosphere micro-ecologicy influence the fruit tree cultivation and fruit quality. Based on the causes of continuous cropping obstacles of fruit trees， this paper analyzes the impact of continuous cropping of fruit trees on microbial diversity and the response of soil microbial diversity to continuous cropping of fruit trees. It summarizes the solutions to replant diseases， and aims to provide help for the repair of continuous cropping obstacles of fruit trees.

Key words Continuous cropping obstacle;Soil microbial diversity;Rhizosphere micro-ecology;Fruit tree
