在干旱条件下,选用郑单958和农大108为供试材料,在不同种植方式(平作、垄作和起垄覆膜)及不同种植粒数(单粒和双粒播种)下,研究其耗水规律及水分利用效率。结果表明:相同品种间,起垄覆膜在拔节至灌浆期,耗水量大于平作和垄作,灌浆至成熟期,耗水量小于平作和垄作;整体上,郑单958水分利用效率高于农大108;种植粒数处理之间没有差异。因此,采用起垄覆膜方式,选用合理品种.是提高玉米抗旱性和保证产量的有效途径。
在榦旱條件下,選用鄭單958和農大108為供試材料,在不同種植方式(平作、壟作和起壟覆膜)及不同種植粒數(單粒和雙粒播種)下,研究其耗水規律及水分利用效率。結果錶明:相同品種間,起壟覆膜在拔節至灌漿期,耗水量大于平作和壟作,灌漿至成熟期,耗水量小于平作和壟作;整體上,鄭單958水分利用效率高于農大108;種植粒數處理之間沒有差異。因此,採用起壟覆膜方式,選用閤理品種.是提高玉米抗旱性和保證產量的有效途徑。

Choosing nongda 108 and zhengdan 958 as maize varieties under drought condition ,the effect of different planting modes (flatten culture, ridge culture, ridge forming and film mulching) and different planting grain numbers (single grain sowing, double particles sowing )on water consumption laws and water use efficiency of maize was studied.The results showed that between the same variety ,water consumption of ridge forming and film mulching was larger than that of flatten culture and ridge culture from jointing to watery stage, but was lower than that of flatten culture and ridge culture from watery to maturity stage.On the whole ,water use efficiency of zhengdan 958 was higher than that of nongda 108 ,and there was no differences between single grain sowing and double particles sowing. So using ridge forming and film mulching and choosing right varieties were the effective ways to improve the drought resistance and guarantee yield of maize.
