通过对苹果等果园进行4年的覆草研究,发现果园覆草可提高土壤有机质含量1.39%,每立方厘米降低容重0.56克,提高土壤孔隙度24.7%,提高果树光合效率近一倍。因而促进果树生长发育、提高果品产量和质量。
After 4 years of covering apple orchards with grass, it was found that orchard mulching increased soil organic matter content by 1.39%, decreased bulk density by 0.56g per cubic centimeter, increased soil porosity by 24.7% and nearly doubled the photosynthetic efficiency of fruit trees. Thus promoting the growth and development of fruit trees and increasing the output and quality of fruit products.
