我国黄土高原地区，光、气、热资源丰富，而水资源不足，土壤肥力较低，这是栽培果树的限制因子。为了经济利用土壤水分，逐渐培肥土壤，近年来我们采取限制性生草地面植被管理技术，取得了土壤节水与培肥的双重效果，主要技术环节如下：一、地面植被类型果园在定植后的1－2年 China’s Loess Plateau, light, gas and heat rich in resources, and lack of water resources, soil fertility is low, which is the limiting factor for the cultivation of fruit trees. In order to economically utilize soil moisture and gradually fertilize the soil, in recent years we have adopted the restrictive grass-and-fodder vegetation management technology and achieved the dual effects of soil water conservation and fertilization. The main technical aspects are as follows: 1. The orchard types of ground- 1-2 years
