| 摘 要： | 由于南疆水资源时空分布不平衡,春旱成为困扰小麦持续高产的问题。从土壤水、灌溉水综合调控的角度,研究了小麦冬灌水量对土壤水库和小麦分蘖过冬存活的影响。结果显示:(1)小麦冬灌时不同的灌水量会形成差别很大的越冬土壤水库,常规灌水量下麦田越冬土壤水库较灌水前减小;(2)土壤水库大小对小麦分蘖越冬成活数量有影响,随着土壤水库增大单位基本苗发育成活的分蘖数提高;(3)综合考虑土壤水库大小、小麦越冬分蘖成活情况和土壤水渗漏等因素,初步确定和田地区沙性土壤小麦冬灌水量以116 m3/667 m2为宜。

| Abstract: | Spring drought influences wheat growth heavily in south Xinjiang.The paper studyed effects of irrigation water amount in fall on soil water reservoir and survival branch in Hetan region of Xinjiang.The results showed that different irrigation water amount could have different soil water reservoir,and the routine irrigation water amount could decrease soil water reservoir.The amount of soil water reservior,surival branch of overwintering wheat and percolation of soil water were synthetically studied.The irrigation water amount in fall should be 116 m3/667 m2 in sandy soil in Hetan region of Xinjiang. |
