摘  要：
【目的】库尔勒香梨是新疆库尔勒地区的特色支柱产业。新疆干旱少雨、蒸散量大,研究滴灌条件下库尔勒香梨耗水特征,为制定合理的库尔勒香梨滴灌灌溉制度提供数据支撑。【方法】测量滴灌条件下库尔勒香梨园土壤含水量,分析不同水分处理的耗水强度、植株蒸腾强度等指标的变化规律,研究滴灌条件下库尔勒香梨的耗水特征。【结果】滴灌条件下萌芽期的库尔勒香梨耗水强度为0.12~1.30 mm/d,花期、展叶期耗水强度在0.12~1.32 mm/d,坐果期为4.37~9.78 mm/d,果实膨大期为2.8~10.3 mm/d,收获期为3.29~6.11 mm/d。库尔勒香梨耗水模数在坐果期达到最大,占整个生育期的37%~40%,果实膨大期为28%~39%,在萌芽期和花期仅为0.3%~1.7%。【结论】在整个库尔勒香梨生育期中,由于坐果期和果实膨大期的持续时间最长,其耗水量占整个生育期的83%~91%,为库尔勒香梨需水的关键时期,采用滴灌条件能更好的制定合理的灌溉制度,及时精确灌溉,为库尔勒香梨节水增产提供支撑。

摘  要：
【Objective】Korla Pear as a pillar industry in Xinjiang Korla region,due to special natural condition restrictions such as drought,high evapotranspiration,which result in such problems as too high water irrigation quota in water management and too high consumption and low efficiency and other issues in Korla. In this paper,using drip irrigation technology,irrigation quota under conditions of water consumption characteristics of each treatment were analyzed to clarify the law of water consumption under drip irrigation for providing reasonable data support.【Method】By measuring the moisture content of the soil under drip irrigation of Korla fragrant pear,analyzing water consumption intensity variation of different water treatment and plant transpiration rate and other indicators,the conditions under drip water features in Korla Pear areas were better understood.【Result】The results showed that: under drip irrigation Korla pear water budding strength was 0. 12- 1.30 mm / d,at the flowering and leaf stages,water intensity was between 0. 12- 1. 32 mm / d,and during fruit setting period,it was 4. 37- 9. 78 mm / d,amd in fruit enlargement period,it was 2. 8- 10. 3 mm / d,and the harvest period was 3. 29- 6. 11 mm / d. Korla Pear fruit water modulus reached the maximum,accounting for37%- 40% of the entire growth period,among which,the fruit enlargement period was 28%- 39%,budding and flowering was only 0. 3%- 1. 7%. 【Conclusion 】the water consumption of Korla pear in the whole growth period,due to the longest duration of the fruit and fruit enlargement,accounts for 83%- 91% of theentire growth period,which is actually the critical period for the Korla Pear water demand. So the use of drip irrigation under these conditions can better and more reasonably help to set down an irrigation system which will contribute to execution of accurate and timely irrigation and support for the water- saving production of the pears.
