幼龄果园套种竹豆生态效益试验研究

Experimental Study on Ecological Benefit by Interplanting Phaseodus Calcaltus with Young Fruit Trees in Orchard

幼龄果园套种竹豆绿肥与清耕相比可减少径流70％、泥沙80％以上,对改善园地土壤水肥、温湿条件,促进幼树的营养与生殖生长均有明显的作用。积极推广套种竹豆绿肥是幼龄果园水土保持建设和果品丰产的重要措施。

Compared with ploughing without any grass,interplanting phaseodus calcaltus with young fouit trees in orchard can reduce runoff by more than 70% and sediment by more than 80%. This system can improve the condition of soil moisture, temperature and fertility, accelerating obviously vegetative growth and increasing greatly reproductive capacity. It is an important measure to popularize the interplanting system for soil and water conservaiton and fruit bump harvest.
