摘要: 通过2004年棉花生长季田间试验,我们研究了膜下滴灌棉花关键生育期不同灌水量和灌水次数对其生长、产量及水分利用效率(WUE)的影响,旨在建立河北南部棉区滴灌条件下的优化灌溉模式,提高作物水分利用效率,达到节水增产目的。试验结果表明:不同灌水方式对棉花产量和水分利用效率的影响具有显著差异,棉花需水关键期花铃期分2次少量灌水处理,每次灌水量10.42mm,明显优于两次多量灌水和集中一次灌溉等其他处理,产量和WUE最高,分别高达4929.0kg/hm2和0.98kg/m3,具有明显的节水增产效益。

关键词: 棉花, 膜下滴灌, 关键生育期, 水分利用效率

Abstract: Based on the field experiment of cotton irrigation in 2004,the effects of irrigation quantity and frequency of drip irrigation to plastic-mulched cotton at critical growing stage was studied on growth,yield and water use efficiency(WUE).We hoped to find out the optimum irrigation mode which could increase the yield and improve WUE.The results of the experiment showed that the different irrigation modes had significant effect on the cotton yield and WUE.However,different irrigation modes had little effect on the stem height and leaf area at postbudding stage.Cotton which was irrigated two times at bolling stage,10.42mm each time,obtained the highest yield about 4929.0kg/ha and the highest WUE about 0.98kg/m3 respectively.

Key words: Cotton, Drip irrigation under plastic-mulched, Critical growing stage, WUE
