重茬果园再植障碍已成为制约果树更新换代和果业持续健康发展的瓶颈。为规范重茬果园标准化管理，通过对重茬果园土壤改良技术的多年试验，研究总结了山地重茬果园土壤绿色改良技术规范。从适用范围、规范性引用文件、术语定义、土壤绿色改良、抗重茬砧木选择、脱毒苗栽植等方面规范了重茬果园土壤改良技术，为山地重茬果园标准化管理和林果产业高质量绿色生产提供科学依据和技术支撑。

The obstacle of replanting orchards has become a bottleneck that restricting the replacement of fruit trees and the healthy and sustainable development of the fruit industry. In order to standardize the management of replant orchards, the technical specifications for soil green improvement in mountainous replant orchards were studied and summarized through years of experiments on replant soil improvement. From the scope, normative reference documents, term and definition, soil green improvement, resistance to repeat cropping stock, virus-free seedling planting and so on, the soil improvement technology of repeat cropping orchards was standardized. It provides scientific basis and technical support for standardized management of mountainous replant orchards and high-quality green production of forest fruit industry.
