摘要
李园生草不仅可以抗旱、保墒,提高土壤肥力,改善土壤结构,而且能够增强果园的观赏效果,是现代果业生产的重要栽培管理技术。研究表明:李园生草平均提高土壤有机质含量9%,全氮含量提高43%,速效氮、磷、钾分别提高22.7%、19.3%、19.9%;还可增加土壤田间持水量和孔隙度。
Sown grass in plum orchard can not only resist drought, hold water content, increase soil fertility, improve soil structure, but also improve the viewing effect of orchard. It is a kind of important cultivation technique in modern fruit production. The results showed： Sown grass in plum orchard could increase soil organic substance, total N, available N, available P, and available K 9%, 43%, 22.7%, 19.3%, 19.9% , respectively. Moreover, it could increase soil porosity and field water content.
