| 摘 要： | 为探究加气渗灌模式下灌水定额和秸秆还田深度对棉花生长和产量的影响,本文以“新陆中88号”为研究对象,探究灌水定额和秸秆还田深度对棉花株高、茎粗、干物质量以及叶绿素相对量的调控效应,棉花受灌水定额影响较大,植株株高、茎粗、植株干物质量和叶片叶绿素相对量均随着灌水定额的增大呈增加趋势。同一灌水定额条件下,D2处理的叶绿素相对量大于D1和D3处理,且在灌水定额相同条件下,秸秆还田深度为25cm时,棉花株高、茎粗以及单株棉花籽棉产量均为最佳,为南疆棉秆还田和水气渗灌技术提供了一定技术参考。

| Abstract: | In order to investigate the effects of irrigation quota and straw return depth on the growth and yield of cotton under aerated percolation irrigation mode, this paper took "Xinluzhong 88" as the research object to investigate the effects of irrigation quota and straw return depth on the regulation of cotton plant height, stem thickness, dry matter mass and relative amount of chlorophyll, which were greatly affected by the irrigation quota. Cotton was more affected by the irrigation rate, and plant height, stem thickness, plant dry matter mass and relative amount of leaf chlorophyll tended to increase with the increase of irrigation rate. Under the same irrigation quota, the relative amount of chlorophyll in D2 treatment was greater than that in D1 and D3 treatments, and under the same conditions of irrigation quota, when the depth of straw returned to the field was 25cm, the height of cotton plant, stem thickness and seed cotton yield of single cotton plant were all optimal, which provided a certain technical reference for the cotton straw returned to the field and water and gas infiltration irrigation in southern Xinjiang. |
