The yield ( Ye ), water use efficiency ( WUE ), leaf area duration (LAD ), and crop growth rate ( CGR ) in the compound canopy of intercropped wheat and maize were analyzed under limited supplemental irrigation with water harvesting in dryland.
对旱塬地区小麦套作玉米带田集雨限量补灌条件下带田产量、水分利用效率、叶日积(LAD)及作物复合群体生长率(CGR)进行了分析研究,认为该区发展小麦玉米带田限量补灌(35mm)的最佳生育时期为小麦抽穗期和玉米抽雄开花期,有条件时灌2水以小麦抽穗期、玉米抽雄开花期和小麦扬花期、玉米吐丝期为宜。

| 董志塬 位于中国甘肃省东部。汉代称彭池塬，简称彭塬。北起驿马关至庆阳城一线，南止泾河谷地，东西介于马连河和蒲河间。包括甘肃省庆阳县大部及宁县、合水县各一部分。南北长87千米，东西宽36千米左右。面积2260平方千米。为陇东面积最大而较平坦完整的黄土塬。塬面海拔1200～1450米。有13条较大河沟呈辐辏状向塬心伸入，分割塬面成多数碎块。一般沟壑深150～200米。大小沟壑占面积的61％，荒坡又占沟壑面积57％。塬面年降水量约在500毫米左右，年均温8～10℃，无霜期150～180天。为冬小麦主产区。 |
