摘要

旱作苹果园深沟集中施肥的方法具有改善根区养分状况的作用

使土壤pH值降低

有机质和全氮的分解利用加快

特别是磷肥肥效显著提高

在根区形成了一个土壤肥库。该文还提出了在苹果生产上应用的具体建议。

Abstract

In this paper

inethod of deep-ditch manuring in arid farming apple orchard was evaluated. Deep-ditch manuring method possessed the action improving nutrient condition around root system. The soil pH was reduced. The decomposition and the utilization of soil nitrogon and organic matter were accelerated. Particularly

efficiency of phosphate fertilization was improved remarkablely. A so-called fertilizer reservoir around root system was formed. Finally

some suggestions were recommended for .fruit production.
