旱地苹果园渗灌补水加覆盖技术研究与应用

Research on Technology of Seepage Irrigation Water Supplementation Plus Mulching in Rainfed Land Orchards and Its Application

针对黄土高原旱原地发展苹果树干旱缺水的矛盾和果园大水漫灌浪费严重的问题，进行了渗灌补水加秸秆覆盖栽培技术研究与应用。该项技术在解决我国北方半干旱地区发展果树生产供水不足的矛盾方面，具有节水、节能、保水、保肥、省投资、省工等优点。

This paper deals with the cultivation technology of seepage irrigation water supplementation plus straw mulching and its application with the purpose to solve the contradiction between water deficiency and droughts in developing apple trees and the problem of flood irrigation to waste water in orchards on the rainfed loess plateau. This technology is characterized by water saving,energy saving,water and fertility perservation,investment saving and working days saving in solving the contradiction of water supply deficiency in developing fruit tree production in the semi arid areas in North China with economic returns improved apparently.
