摘要:

【目的】研究不同灌溉方式对塔里木盆地西北缘草甸土库尔勒香梨园对土壤含水量、产量和品质的影响,建立库尔勒香梨园漫灌结合滴灌模式下的灌溉制度。【方法】根据研究区的土壤水分物理性质,设计4种滴灌方式,通过Diviner 2000调查土壤含水量,比较产量和品质。【结果】慢速充分滴灌下的土壤含水量可达田间持水量的92%,快速滴灌显著降低了湿润效果。在萌芽期和幼果期,土壤含水量占田间持水量的30%~55%,在膨果期和成熟期,土壤含水量占田间持水量的65%~85%。萌芽期的土壤储水量为80 mm,约为幼果期的1/2,膨果期和成熟期的1/3。萌芽期和花期的耗水量较小,均低于50 mm,幼果期的耗水量显著增大,大于150 mm,膨果期达到顶峰,超过200 mm。慢速充分滴灌下的单果重显著提升,产量提升34%。【结论】漫滴结合模式适宜的滴灌定额为50 m3,漫灌1次,滴灌4次,灌溉定额为5 250 m3/hm2,节水42%,单产1 235 kg/667m2。根据土壤储水量和耗水量变化规律,优化后的灌溉制度为漫灌1次,滴灌7次,灌溉定额为7 500 m3/hm2,节水17%。

Abstract:

【Objective】 To study the effects of different irrigation methods on soil moisture content, yield, and quality and establish an irrigation system under the combination of flood irrigation and drip irrigation in Korla pear orchard by using the Korla Fragrant Pear Orchard at meadow soil in the northwest of Tarim Basin as the research object. 【Methods】 According to the physical properties of soil moisture in the study area, four drip irrigation methods were designed to investigate the soil water content by Diviner 2000 and compare the yield and quality. 【Results】 The soil water content under slow-full drip irrigation could reach 92% of the field capacity, fast-full drip irrigation significantly reduced the wetting effect. In the germination stage and young fruit stage, the soil water content accounted for 30%-55% of the field moisture capacity, and in the fruit expansion stage and ripening stage, the soil water content accounted for 65%-85% of the field moisture capacity. The soil water storage capacity during the budding stage was 80 mm, which was about half of that during the young fruit stage and one-third of that during the swelling and ripening stages. The water consumption during the budding and flowering stages was relatively small, both below 50 mm. The water consumption during the young fruit stage significantly increased, exceeding 150 mm, and the swelling stage reached its peak, exceeding 200 mm. The single fruit weight significantly increased under slow and full drip irrigation, resulting in a 34% increase in yield. 【Conclusion】 The suitable drip irrigation quota for the mixed drip mode is 50 m3, with one flood irrigation and four drip irrigation, and when the irrigation quota is 5,250 m3/hm2, 42% water can be saved and yield arrive at 1,235 kg/667m2. According to the changes in soil water storage and consumption, the optimized irrigation system consists of one flood irrigation and seven drip irrigation, with an irrigation quota of 7,500 m3/hm2, thus saving 17% water.
