摘    要:本文研究了不同水分处理对晚稻生长和产量的影响。结果表明,在节水条件下,K优817长期无水层处理不仅会造成植株株高下降,而且会影响叶片的生长,干湿处理的分蘖高峰期发生早,田面温度提高,株高整齐度好;齐穗后断水时间会影响水稻产量尤其是结实率,T1、T2和T3的单株丛产量平均值分别比对照产量减少48.8%、46.1%和21.0%。结实率分别比对照减少38.8%、37.3%和15.2%。断水时间越早,对结实率影响愈大。

关 键 词:水稻  水分  断水时间  生长  产量

Abstract:The effects of different water treatment on the growth and grain yield of late season rice were studied.The results showed that,the plant height of Kyou 817 and its leaf area and length were reduced under no water layer irrigation;but under the dry and water irrigation,the peak of tillers occurred ahead,surface temperature of farmland increased,plant height uniformed.The yield especially fertility decreased after full-heading,the treatment of T1,T2 and T3 the yield respectively decreased 48.8 %,46.1 % and 21.0 % compared with CK,and the fertility decreased 38.8 %,37.3 % and 15.2 % respectively.The earlier stage the water supply was cut of at the more serious the yield reduce.
Keywords:rice  water  water-cut-off  growth  yield
