小麦受旱对产量及生育性状影响研究

Study on Production and Growing Characters of Wheat at Different Droughts Levels

[目的]研究小麦不同生长发育阶段、不同受旱水平对其产量及生育性状的影响。[方法]分别采取坑测法和筒测法,设置轻旱、中旱和重旱3个水分亏缺水平,检测不同水平下小麦不同生长阶段的产量及生育性状变化,同时分析土壤水分、腾发量以及产量3者之间的关系。[结果]小麦水分亏缺对产量及株高、穗长等生育指标均有影响,土壤水分、腾发量及产量3者呈正相关趋势。[结论]为实施小麦田间水分管理和节水灌溉提供依据。

[Objective] Study on production and growing characters at different development stages and droughts levels of wheat.[Method]The 3 droughts levels of light,middle and heavy were set up,the pit checking cylinder checking method was used to determine the production and growing characters at different droughts levels on different development stages of wheat.And the relationships of them were analyzed.[Result]The drought had effect on production,strain height and spike length.There was a positive correlation trend of soil moisture,evaporation and production.[Conclusion]The research could provide a basis for the water management and saving water irrigation of wheat field.
