| 摘 要： | 采用盆栽人工控制水分方法,研究了开花期水分胁迫对水稻生长发育及产量的影响。结果表明:土壤湿润处理(H1)水稻千粒重27.1 g,比对照重12.9%,差异极显著(P<0.01),处理H1每盆产量152.1 g,高于对照(146.6 g),但差异不显著;中度水分胁迫处理(H2)每盆产量124.4 g和重度水分胁迫处理(H3)每盆产量118.6 g均低于对照,差异极显著(P<0.01)。水稻开花期保持土壤湿润有利于籽粒增重,提高产量又节约水资源。

| Abstract: | The effects of water stress on growth and yield of rice in blooming stage were studied by pot planting and water controlling.The results showed that 1000-grain weight under field wetness treatment(H1) was 27.1 g,12.9% higher than that of the control,and the difference was extremely significant(P<0.01).Yield of treatment H1 was 152.1 g,higher than that of the control(146.6 g),but the difference was not significant.Yield of treatment H2(medium water stress) was 124.4 g and that of treatment H3(heavy water stress) was 118.6 g,lower than that of the control,and the difference was extremely significant(P<0.01).Maintaining filed wetness increases rice grain weight in blooming stage,saves water resources and improves yield. |
