摘要
选择近年来吉林省西部半干旱松原地区广泛种植的玉米品种作为试验材料,对膜下滴灌玉米产量和水分利用效率进行了系统分析。结果表明,在20个玉米品种中,全生育时期内耗水高峰均出现在拔节—抽雄期和抽雄—灌浆期。其中,郑单958、先玉335、铁研24、良玉66和良玉99整个生育时期内耗水量较低,在465mm以下;农大364、禾玉3和宏育29耗水量较高,均在500mm以上。群体水分利用率(WUE)和籽粒产量以良玉99和良玉66较高,而穗位叶水分利用率(LWUE)则以先玉335和郑单958最高。在实际生产中,可优先选择良玉99和良玉66玉米品种。
Different maize varieties,which were planted widely in the western of Jilin province,were selected to study their yield and water use efficiency under-mulch-drip irrigation.The results showed that in the 20 tested maize varieties,the peak of consuming water occurred during the elongation to filling stage.The water consumptions of Zhengdan958,Xianyu335,Tieyan24,Liangyu66 and Liangyu99were lower,and water consumptions of Nongda364,Heyu3 and Hongyu29were higher.Compared with other maize varieties,the water use efficiencies of yield of Liangyu99 and Liangyu66were higher,and those of ear-leaf of Xianyu335 and Zhengdan958were higher.Lianyu99 and Liangyu66should be chosen preferentially to be main varieties to achieve the high and stable yield combining the corresponding cultivate technology.
