摘要:

【目的】研究不同灌水定额及滴灌频次对棉花生理、生长特性及产量的影响规律。【方法】在新疆阿克苏地区沙雅县开展大田试验。试验共设计5个不同灌水定额及滴灌频次处理(S1:675 m3/hm2,S2:900 m3/hm2,S3:1 125 m3/hm2,S4:675 m3/hm2+450 m3/hm2,S5:675 m3/hm2+300 m3/hm2+150 m3/hm2),1个冬灌对照处理(CK:2 700 m3/hm2),分析不同水分处理对棉花生理、生长状况及产量的影响。【结果】(1)在株高及干物质量表现上,随灌溉定额增加,在苗期至吐絮期呈先减小后升高的趋势,其中CK与S1处理在苗期无显著差异,与S3处理在蕾期至吐絮期差异性较小。随滴水频次增加,在苗期至吐絮期呈显著升高趋势,其中CK与S5处理差异性较小。(2)在叶绿素荧光表现上,随灌溉定额增加叶绿素荧光参数呈显著降低趋势,其中CK显著大于各灌水定额处理。随滴水频次增加叶绿素荧光参数逐渐增加,其中CK与S5处理荧光参数差异性较小。叶绿素荧光参数Fm'值与棉花群体叶面积指数呈良好线性关系,Fo'值与干物质累积量建立的相关性模型决定系数较高。(3)在群体生理指标及产量表现上,随灌溉定额及滴水频次增加棉花群体生理指标呈逐渐升高的趋势,其中CK与S5处理差异性较小。各干播湿出处理中S5处理棉花产量及灌溉水分生产效率显著较高,与CK处理相比,产量大小无显著差异,灌溉水分生产效率升高26.7%。【结论】低出苗水量、高滴水频次处理(S5)对于棉花生长促进作用更强,作物产量更高,且有着较高的灌溉水分生产效率,能够达到节水增产的目的。

Abstract:

【Objective】This project aims to study the influence of different irrigation quota and drip irrigation frequency on cotton physiology. 【Methods】Growth characteristics and yield by performing field experiments in Shaya County, Aksu Prefecture, Xinjiang. Five different irrigation quota and drip irrigation frequency treatments (S1:675 m3/hm2, S2:900 m3/hm2, S3:1,125 m3/hm2, S4:675 m3/hm2+450 m3/hm2, S5:675 m3/hm2+300 m3/hm2+150 m3/hm2) and one winter irrigation control treatment (CK:2,700 m3/hm2) were designed to analyze the effects of different water treatments on cotton physiology, growth and yield.【Results】(1) As for the performance of plant height and dry matter quality, with the increase of irrigation quota, it first decreased and then increased from seedling stage to boll opening stage. There was no significant difference between CK and S1 treatment at seedling stage, and there was little difference between CK and S3 treatment from bud stage to boll opening stage. With the increase of drip frequency, it increased significantly from seedling stage to boll opening stage, and the difference between CK and S5 was small. (2) In the performance of chlorophyll fluorescence, the chlorophyll fluorescence parameters decreased significantly with the increase of irrigation quota, and CK was significantly greater than that of each irrigation quota treatment. Chlorophyll fluorescence parameters increased with the increase of dripping frequency, and the difference between CK and S5 was small. The chlorophyll fluorescence parameter Fm' had a good linear relationship with the cotton population leaf area index, and the correlation model between Fo' and dry matter accumulation had a high determination coefficient. (3) In terms of population physiological indexes and yield performance, the population physiological indexes of cotton showed a gradually increasing trend with the increase of irrigation quota and drip frequency, and there was little difference between CK and S5. In each dry sowing and wet-out treatment, S5 treatment had significantly higher cotton yield and irrigation water production efficiency. Compared with CK treatment, there was no significant difference in yield, and the irrigation water production efficiency increased by 26.7%.【Conclusion】Comprehensive analysis shows that the treatment of low seedling emergence water volume and high dripping frequency (S5) has a stronger promoting effect on cotton growth, higher crop yield, higher irrigation water production efficiency, and can achieve the purpose of water saving and yield increasing.
