| 摘 要： | 在大田条件下,研究不同灌溉量对干旱半干旱地区春小麦生长及产量构成的影响,以期为春小麦节水灌溉提供理论依据.结果表明,灌溉量为4 286 m3/hm2(常规对照灌溉量4 495 m3/hm2,减少209 m3/hm2)未对春小麦生长及产量造成不利影响;灌溉量为3 6 70 m3/hm2(比常规灌溉量减少825 m3/hm2)对春小麦生长产生了部分不利影响,但没有使产量明显降低;灌溉量为3 060 m3/ hm2(比常规对照减少1 435 m3/hm2)使春小麦株高降低、干鲜重减少、产量明显减少,对春小麦生长及产量产生明显不利影响.综合考虑,正常年份宁夏引黄灌区春小麦适宜灌溉量在3 900～4 200 m3/hm2,尚有200～5 00 m3/hm2的节水潜力.

| Abstract: | To supply scientific evidences of saving water,a study was made on effects of different irrigation quota on the growth and yield of spring wheat in field conditions in arid and semiarid regions.The results showed that the growth and yield of spring wheat was unchanged under irrigation quota of 4 286 m3/hm2(209 m3/hm2 less than comparison treatment).Though irrigation quota of 3 670 m3/hm2(825 m3/hm2 less than comparison treatment) influenced the growth of spring wheat,but the yield did not reduce obviously.I... |
