| 摘 要： | 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。

| Abstract: | 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 ... |
