| 摘 要： | 为提高小麦水分生产效率,设置了3种灌溉决策方式:Prwin软件决策、彭曼公式决策、经验灌溉(对照),研究其对小麦产量、水分生产效率及相关性状的影响。结果表明:Prwin灌溉决策下,小麦整个生育期灌水2151.0 m3/hm2,比对照节水699.0 m3/hm2,小麦株高、旗叶性状、穗部性状与对照无明显差异,产量达7401.4 kg/hm2,比对照增产7.8%,小麦水分生产效率为1.80 kg/m3,比对照增加26.8%;彭曼公式决策下,比对照节水400.5 m3/hm2,比对照增产4.2%,水分生产效率比对照增加4.1%。

| Abstract: | To improve the water use efficiency of wheat, three irrigation decision-making ways, including Prwin software decisions, Peng Man formula, experience irrigation (control), were set to study their effects on yield, water production efficiency and related properties of wheat. Results showed that, under the Prwin irrigation decision-making way, wheat irrigation amount during the whole growing period was 2151.0 m3/hm2, saving 699.0 m3/hm2 compared with control; plant height, flag leaf and panicle traits showed no significant difference compared with control; the yield reached 7401.4 kg/hm2, with an increase of 7.8% compare with control; water use efficiency of wheat was 1.80 kg/m3, with an increase of 26.8% compared with control. Under Peng Man formula way, compared with control, 400.5 m3/hm2 irrigation amount was saved, with yield increase of 4.2% and water use efficiency increase of 4.1%. |
