Abstract

Abstract:

【Objective】 Fertilizer and salt using salt water resources under film salt water drip irrigation aiming at the arid environment in southern Xinjiang.【Methods】 In this experiment, different salt water mixing ratio of light and salt water and nitrogen application were set, the cotton growth indexes in different reproductive periods were observed, and the water and nitrogen utilization efficiency was analyzed through the final yield to determine the appropriate mixing proportion of light and salt water and nitrogen application rate.【Results】 the growth indexes and yield of cotton were significantly affected by the salinity of irrigation water and the amount of nitrogen application(P<0.05); With the increase of salinity of irrigation water, the growth indexes of cotton and the yield of seed cotton decreased significantly(P<0.001), while the increase of nitrogen fertilizer could significantly improve the growth indexes of cotton and the yield of seed cotton(P<0.05). Mixing fresh water and salt water for irrigation can significantly improve the utilization efficiency of irrigation fresh water(P<0.001); At the same time, increasing nitrogen fertilizer can significantly improve the irrigation fresh water use efficiency(P<0.001) and water use efficiency(P<0.05), while the partial fertilizer productivity decreases(P<0.001); Therefore, when reusing the mixed irrigation of salt water and fresh water, in addition to controlling the salinity of mixed irrigation water, it is also necessary to control the amount of nitrogen application while increasing the yield and ensuring the nitrogen use efficiency.【Conclusion】 Under the condition of reducing the use of fresh water by 20%, the yield (6,829.80 kg/hm²) and water use efficiency (0.97 kg/m³) reach the control treatment level.

Key words: cotton; mulched drip irrigation; salt water; nitrogenous fertilizer; growth index; yield; water and nitrogen utilization efficiency

摘要：

【目的】研究膜下咸水滴灌条件下利用咸水资源高效的水肥盐综合管理模式。【方法】设置不同淡咸水混合比例和施氮量,观测不同生育期棉花生长指标,通过最终产量分析水氮利用效率,分析适宜的淡咸水混合比例和施氮量。【结果】棉花各项生长指标和产量受灌溉水矿化度和施氮量影响显著(P<0.05);随着灌溉水矿化度的增加,棉花各生长指标和籽棉产量显著降低(P<0.01),而增施氮肥能显著提高棉花各生长指标和籽棉产量(P<0.05)。将淡水与咸水混合灌溉,灌溉淡水利用效率显著提高(P<0.01);增施氮肥可以显著提高灌溉淡水利用效率(P<0.01)和水分利用效率(P<0.05),而偏肥生产力降低(P<0.01);再利用咸水与淡水混合灌溉时,除需控制混合灌溉水矿化度外,在增施氮肥提高产量的同时还需控制施氮量保证氮肥利用效率。【结论】淡咸比例4∶1灌溉合理的增施氮肥在减少20%淡水使用的情况下,产量(6 829.80 kg/hm²)和水分利用效率(0.97 kg/m³)达到了对照处理水平。
