Abstract:

【Objective】 To explore the effects of different upper and lower limits of soil moisture on the growth and yield of machine-harvested Gossypium barbadense in Southern Xinjiang in the hope of providing theoretical basis for field water management of the crop. 【Methods】 A two-year field experiment was carried out with Gossypium barbadense as the research object. In 2021, three irrigation lower limits were set as 50%, 60% and 70% field water holding capacity (FC), three irrigation upper limits were set as 80 %, 90% and 100% FC and eight treatments of different combinations (Wa-1-Wa-8). In 2022, the irrigation upper limit was set at 90% FC, three irrigation lower limits were set at 55 %, 65 % and 75 % FC in bud stage, and three irrigation lower limits were set at 60%, 70% and 80% FC in flower and boll stage. Nine treatments (Wb-1-Wb-9) were completely combined. Based on the difference of growth indexes, yield composition and water use efficiency under different irrigation schemes, the better experimental treatment was selected by AHP-EWM-RSR comprehensive evaluation method. 【Results】 The results showed that the increase of irrigation lower limit at bud stage significantly increased plant height and stem diameter. The irrigation lower limit of 70 % FC at flowering and boll stage was beneficial to increase yield and water use efficiency, and there was no significant difference in harvest density. The seed cotton yield of Wb-5 treatment (65 % FC-90 % FC at bud stage and 70% FC-90% FC at flowering and boll stage) was 6.33 t / hm2, which was 10.86 % higher than that of CK-2, and its water use efficiency was 73.17% higher than that of CK-2. 【Conclusion】 Bud stage are 65% -90% FC, and the upper and lower limits of irrigation at flower and boll stage are 70 % -90 % FC, which can promote growth and increase yield and water use efficiency.

摘要:

【目的】 探究新疆南疆机采长绒棉不同土壤水分上下限对其生长及产量的影响,为长绒棉田间用水管理提供理论依据。【方法】 以长绒棉为研究对象,设置2年大田试验,2021年3个灌水下限分别为50%、60%和70%田间持水量(FC),3个灌水上限80%、90%和100% FC及其不同组合的8个处理(Wa-1~Wa-8);2022年设置灌水上限为90% FC,在蕾期设置3个灌水下限分别为55%、65%和75% FC,花铃期设置3个灌水下限为60%、70%和80% FC完全组合的9个处理(Wb-1~Wb-9)。基于不同灌溉方案下生长指标、产量构成及水分利用效率等的差异,采用AHP-EWM-RSR综合评价法选取较优的试验处理。【结果】 增大蕾期灌水下限长绒棉株高和茎粗显著提升;花铃期70% FC的灌水下限有利于提高长绒棉产量和水分利用效率,而收获密度差异不显著,其中Wb-5处理(蕾期灌水上下限65%FC~90%FC,花铃期灌水上下限70%FC~90%FC)籽棉产量为6.33 t/hm2,较CK-2提高10.86%,其水分利用效率提高73.17%。【结论】 蕾期灌水上下限为65%~90% FC,花铃期灌水上下限为70%~90% FC,可促进生长并提高长绒棉籽棉产量和水分利用效率。
