| 摘 要： | 综合考虑间歇灌溉缺水期土壤水分含量变化与持续时间长短对水稻的胁迫作用，提出了水分胁迫指数（WSI）的定义(公式见影像原文)。1989-1991年的试验结果：在水稻水分敏感期，WSI与水稻生育指标和产量相关密切，其相关系数较土壤含水量和土水势指标显著提高，可供生产和研究参照应用。

| Abstract: | Based on the comprehensive research,the effects of extent and sustained period of water stress on rice were studied.This paper suggests the defination of WSI:The experiment conducted in 1989-1991 indicates that there is a high correlation degree between WSI and main growth parameters and yield of rice in the water sensitive stage.The correlation coefficient is singnificantly higher than that between the soil moisture and soil water potential,which is usually used in research,and main growth parameters and yield of rice.WSI could be used and introduced in rice production and researches. |
