| 摘 要： | 【目的】研究水氮耦合对棉田土壤水分时空分布及产量效应的影响。【方法】采用裂区试验设计,以灌溉量为主区,设2 250.0 m3/hm2(低灌溉量,W1)、3 450.0 m3/hm2(常规灌溉量,W2)和4 650.0 m3/hm2(高灌溉量,W3),3个灌溉量(W1、W2和W3)。设0 kg/hm2(空白)、300.0 kg/hm2(常规施肥量)和600.0 kg/hm2(高施氮量),3个纯氮投入量(N1、N2和N3),测定土壤水分、盐分含量,以及不同时期棉花植株干物质积累量及不同处理下最终产量,评估不同水氮施用处理下棉花植株生长发育及最终产量变化。【结果】在W3N2处理下土壤中的盐分和水分有着相对较好的吸收能力,相较于W1N1处理盐分消耗量高出64.2%,水分消耗量显著高92.4%;在W3N2水氮施用组合下,花期、铃期、吐絮期这3个时期不同处理下干物质积累量均有显著提高,相较于W1N1处理显著高39.0%。【结论】W3N3水氮施用组合下棉花植株单株铃数、单铃质量、籽棉产量等3项指标达到最高,比W1N1处理显著高30.0%。

| Abstract: | 【Objective】 Research Effects of Water - Nitrogen Coupling on Soil Water Distribution and Yield in Cotton Field. 【Methods】 The split zone test design was adopted, with irrigation amount as the main area, with 2,250.0 m3/hm2( low irrigation),3,450.0 m3/hm2( traditional irrigation) and 4,650.0 m3/hm2( high irrigation), with three irrigation amounts (expressed as W1,W2 and W3). kg/hm2(0 blank), 300.0 kg/hm2 (traditional fertilizer application) and 600.0 kg/hm2 (high nitrogen application), three pure nitrogen inputs (expressed in N1, N2 and N3) were used to carry out field experiments in dry inland cotton areas of northwest China. The effects of different water and nitrogen treatments on the growth and final yield of cotton plants were evaluated by measuring soil moisture, salt content, dry matter accumulation of cotton plants in different periods and final yield under different treatments. 【Results】 The results showed that the salt and water consumption in soil under W3N2 treatment was 64.2% higher and 92.4% higher than those in W1N1 treatment. Under the combination of W3N3 water and nitrogen application, the boll number, boll quality and seed cotton yield of cotton plants reached the highest, which was 30.0% higher than that of W1N1 treatment. 【Conclusion】 It is not that the higher the application of water and fertilizer, the better the growth trend and the higher the yield. On the contrary, the relatively low combination of water and fertilizer application provides more favorable conditions for the growth and development of cotton, which not only provides theoretical basis for field water and fertilizer management, but also effectively controls the amount of water and fertilizer application, which is of great significance in increasing production and income and environmental protection. |
