摘要: 【目的】研究滴灌条件下不同灌溉频率对棉花生长及产量的影响。【方法】在大田灌溉定额(4 650 m3/hm2)下,设置5个灌水频率(3、6、9、12和15 d/次,其中6 d/次为CK),分析灌溉频率对棉花生长发育过程中干物质积累及分配、产量的影响。【结果】高灌溉频率(3 d/次)干物质积累量较大,同化物向生殖器官的分配率较高,开花结铃数也较高,有利于提高籽棉产量和水分利用效率。【结论】在4 650 m3/hm2常规灌溉定额下,3 d/次的高频灌溉能够提高棉花的干物质积累量,有利于籽棉产量和水分利用效率的提高。

关键词: 棉花; 灌溉频率; 物质积累; 水分利用效率

Abstract: 【Objective】 In order to determine the effect of different irrigation frequencies on cotton growth and yield under drip irrigation.【Method】Under the irrigation quota of 4,650 m3/hm2, 5 irrigation frequencies of irrigation (3, 6, 9, 12 and 15 times/d, among which 6 d/ times was CK) were set to analyze the effects of irrigation frequencies on dry matter accumulation, distribution and yield during cotton growth and development peiods.【Result】The results showed that the accumulation of dry matter, the distribution rate of assimilates to reproductive organs and the number of flowering and bolls were higher, which was beneficial to increasing the yield and water use efficiency of seed cotton. 【Conclusion】Under the conventional irrigation quota of 4,650 m3/hm2, the high frequency irrigation of 3 d / time could increase the dry matter accumulation of cotton, and benefit the yield of seed cotton and the increase of water use efficiency.

Key words: cotton; irrigation frequency; material accumulation; water use efficiency
