摘要
根据干旱地区土壤、气候特点,结合当地条件制定的定植穴铺膜、间作绿肥、越冬防寒等果树旱作综合配套技术,使幼树定植成活率由33% 提高到88% ,土壤有机质含量提高46% ,含水量提高26% ,节水效果明显。
The comprehensive technology of fruit trees is studied, according to the characteristics of soil and climate.In dryland regions, the technology include: laying plastic film in the planting hole, intercropping green manure crops between the trees and cold protecting in winter. The survival rate of trees is raised from 33% to 88%, the content of organic matter in soil is raised by 46%,the water content of soil is raised by 26%,saving water obviously.
