摘要: 【目的】在滴灌小区试验条件下,研究南疆绿洲区冬小麦在不同滴水频率下麦田土壤水分分布、田间小气候特征,为制定当地冬小麦滴灌制度提供依据。【方法】在统一冬灌900 m3/hm2的基础上,开春后滴灌4 050 m3/hm2,并设置3个滴水频率:低频P1为4次,中频P2为7次,高频P3为10次。【结果】土壤水分分布受滴水频率的影响较大,高频、中频和低频灌溉处理生育期内0~50 cm 土层平均含水率分别为21.97%、20.04%和19.76%,且高频处理0~30 cm土层含水率更趋于平稳;高频滴灌较中频滴灌和低频灌溉生育期内平均土温降低0.40和0.83℃,冠层内平均温度降低0.37和1.15℃,冠层叶温降低0.42和1.30℃,冠层内相对湿度增加1.11和2.28个百分点,冠层光截获率增加0.025 6和0.055 1;高频滴灌较中、低频滴灌产量和灌溉水利用效率增加1.36%和20.47%。【结论】在南疆绿洲区冬小麦田中,高频滴灌能改善田间小气候,促进产量和水分利用效率的提高,实际应用中以春季7~10次的“少量多次”滴灌模式为宜。

Abstract: 【Objective】 Under the drip irrigation plot test condition, the soil water distribution and field microclimate characteristics of winter wheat under different drip frequencies in the oasis area of Southern Xinjiang were studied in the hope of providing basis for making winter wheat drip irrigation system.【Method】Based on the unified winter irrigation of 900 m3/hm2, after the spring, the drip irrigation amount was 4,050 m3/hm2 using three irrigation frequencies: low frequency P1 was 4, medium frequency P2 was 7, high frequency P3 was 10.【Result】Soil water distribution was greatly affected by drip frequency. The average soil moisture contents of 0-50 cm soil layer in high frequency, medium frequency and low frequency irrigation treatments were 21.97%, 20.04% and 19.76%, respectively, and the soil moisture contents of 0-30 cm layer were more stable when treated with high frequency; In the growth period, the average soil temperature of high frequency irrigation treatment was 0.40℃ and 0.83℃ lower than those of medium and low frequency irrigation treatments the average temperature in the canopy decreased by 0.37℃ and 1.15℃, canopy leaf temperature decreased by 0.42 ℃ and 1.30℃, relative humidity in the canopy increased by 1.11 and 2.28 percentage points, canopy light interception rate increased by 0.025,6 and 0.055,1. Compared with medium frequency and low frequency irrigation treatments, the yield and irrigation water use efficiency of high frequency irrigation treatment increased by 1.36% and 20.47%. 【Conclusion】High frequency drip irrigation in winter wheat field can improve field microclimate and increase yield and water use efficiency in the oasis area of Southern Xinjiang. In practice, 7-10 times drip irrigation model is appropriate after spring.
