| 摘 要： | 以稻田水位为调控指标进行水稻全生育期试验，研究了受涝、受旱和涝渍3种控水条件下水稻茎蘖数和株高的变化规律，并用SPSS软件进行模型拟合。结果表明，农田水位管理可以改变水位茎蘖数和株高的变化趋势,分蘖期内这2个指标对控水条件的敏感性最大,其次为拔节孕穗期。受涝、受旱、涝渍处理均不利于水稻茎蘖数和株高的增加，3种控水处理中...

| Abstract: | Field water level was the index of controlling irrigation and drainage of paddy field,through the experiment on the condition of flood,drought and water-logging,the changes of the growth and development indicators such as the tiller number and plant height.By using the SPSS software,the tiller number and plant height was fitted.The result of study shows that: the tiller number and plant height was changed by different water controlling programs,and they were the most sensitive in the tiller stage while they were secondary in the jointing booting stage.All the water controlling schemes as flood,drought and water-logging were conducive to the tiller number and plant height.And the condition of drought was the most unfavorable while the condition of water-logging was secondary.The effects of flooding were undistinguished. |
