| 摘 要： | 通过冬小麦小区试验,在不同时期给以不同程度的亏水灌溉处理,以研究不同生长时期水分亏缺和亏缺程度对冬小麦生理生态及产量的影响。冬小麦生长发育过程被划分为4个阶段:苗期、拔节期、抽穗期和灌浆成熟期。每个生育阶段设置不同水分水平,结果表明:土壤水分调控对冬小麦株高、叶片叶绿素相对含量,产量和水分利用率均有影响;冬小麦株高以及叶片叶绿素相对含量在拔节期、抽穗期以及灌浆成熟期前期均存在一定的补偿效应。

| Abstract: | Plot experiment with three levels of soil moisture at different growing stages of winter wheat were carried out to study water deficits on physiological and agronomic factors of winter wheat.The growing stage of winter wheat was divided into four stages: seedling,jointing,heading,filling and maturing.Under different soil-water conditions,the plant height and relative leaf chlorophyll contents were measured continually.The results show that water deficits affected plant height,relative leaf chlorophyll conte... |
