不同灌溉频次对陆地棉生长指标和产量的影响
The effect of different irrigation frequencies on the growth indicators and yield of upland cotton
摘要
Abstract
[Objective]To explore the optimal irrigation frequency for cotton under film drip irrigation in southern Xinjiang.[Methods]This experiment used Xin luzhong 54 as the experimental cotton.Through field experiments,four different irrigation frequency treatments were set up:2 d/time(D2),4 d/time(D4),6 d/time(D6),and 8 d/time(D8).The conventional irrigation(CK)of farmers was used as a control treatment to study the response of cotton growth indicators,yield composition,and water use efficiency to different irriga-tion frequencies.Finally,the objective analysis entropy weight method was used to optimize the irrigation fre-quency suitable for subsurface drip irrigation in southern Xinjiang.[Results]Increasing irrigation frequency could promote the growth of cotton plant height,stem diameter,and biomass,and reach the maximum value during the opening period.D2 treatment significantly increased by 9.53％,20.83％,and 32.03％compared to CK treatment(P＜0.05);with the increase of irrigation frequency,the number of bolls per plant and yield of cotton gradually increased.The D2 treatment produced the highest number,reaching 9.21 and 7,546.35 kg/hm2 respectively,but the water consumption was also the highest,at 477.80 mm.The D4 treatment had the highest water use efficiency,at 1.59 kg/m3;The entropy weight results showed that D2 treatment had the highest evaluation result.[Conclusion]The experimental results show that under the film drip irrigation of sandy loam soil in southern Xinjiang,when the irrigation quota during the growth period is 3,750 m3/hm2,the entire growth period is irrigated 40 times,and the optimal irrigation cycle is 2 days.关键词
