摘要

为了取得高产、实现高水分利用率及达到节水的目的

通过野外定位试验在西北干旱荒漠气候区进行葡萄覆膜与不覆膜滴灌的灌溉制度的试验研究。结果表明

膜下滴灌第一种处理T1(240mm)比不覆膜常规滴灌CK(360mm)节水33%

生育期内浆果生长期日耗水量最大

为需水关键期。在当地气候、土壤及试验研究的栽培模式下

葡萄全生育期的灌水量是240mm;葡萄的灌溉制度为全生育期内灌水12次

灌水定额为10～20mm

这种滴灌与覆膜技术相结合的灌溉方法能显著提高葡萄的水分利用效率和产量

为西北干旱荒漠戈壁葡萄园膜下滴灌提供了一种优质高效的节水灌溉模式。

Abstract

In this paper

a field location experiment on the irrigation system of grape was conducted in arid desert climate region of northwest China

under mulching and without mulching

to achieve its high yield and high efficiency of water use.The results showed that or so 33% of water amount could be saved under mulching

the max daily water consumption and the key water demand period of grape was in berry growth period of its whole growth period.The results further indicated that the total water amount of grape in i...
