| 摘 要： | 以绿洲2号为供试材料,采用单因素试验,在水稻全生育期实行不同程度的控水灌溉处理,研究其对水稻生长发育的影响。结果表明,控水灌溉降低了水稻叶面积指数以及茎、叶干物质重量,增加了水稻根部干物质重量,能够促进水稻分蘖,增加植株穗粒数及千粒重,提高产量,试验中控水灌溉处理Ⅱ的产量高于常规灌溉11.04%,且不同处理间差异显著。

| Abstract: | Lvzhou2 was used as the experimental material and studied the effects of different degree control irrigation treatments in the whole growth period on growth and development of rice by using the single-factor test method.The results showed that control irrigation treatment decreased the leaf area index and dry biomass of stem and leaf,improved the weight of dry matter and tillering rate,grain number per hill,1000-grain weight and yields;the yield increased 11.04% on control irrigation disposalⅡthan that of general irrigation,differences were significant in different treatments. |
