| 摘 要： | 通过1987～1990年4年的实测资料,分析了一季晚稻在不同生育阶段内受到水分胁迫情况下的生长发育状况及产量的变化,分析了产量与节水率之间的关系,并对不同处理的节水率、减产率采用方差分析方法进行显著性检验,从而提出了在不影响产量的情况下,各生育期的耐旱极限值。

| Abstract: | The growing status and yield changes of the different stages of the one-season late rice in the water stress and the relationship of yield and water-saving rate have been analysed according to the 4-year measured data of 1987 to 1990.The significance tests of the water-saving rate and yield decreasing rate of different treatments have been proceeded by the variance analyses and the extreme values for drought toteranee in different growing stages without ef- fecting yield have also been presented. |
