Effects of hairy vetch cultivation on soil quality and productivity in Chinese orchards: a meta-analysis

Abstract

To find out the effects of hairy vetch cultivation on soil quality and productivity in Chinese orchards, all relevant papers in China National Knowledge Infrastructure (CNKI) published from 2000 to 2021 were collected to quantitatively analyze the effects of hairy vetch cultivation in orchards on soil physicochemical properties and nutrient content, soil enzyme activity, microbial activity, fruit yield and quality based on meta-analysis. The results showed that the effect sizes of hairy vetch cultivation on soil quality and productivity changed in a positive direction, but part of the effect sizes did not change significantly. This paper provides some support and reference for the development of grass cultivation in orchards.
