摘　　要：【目的】揭示不同滴头流量对土壤水分分布特征、香梨树生长指标的影响,为筛选当地香梨滴灌选择的最佳滴头流量提供理论参考。【方法】以5年生库尔勒香梨为试验对象,通过设定不同的滴头流量,研究滴头流量下土壤水分水平、垂直运移特征以及对香梨新梢长度、粗度、叶片光合特性、果实纵横径、单果质量变化的影响。【结果】滴头流量为q=10 L/h时,土壤水分运移特征与根系分布达到较高吻合,且对香梨果实生长具有较明显的促进作用。【结论】通过试验得出结论最佳滴头流量为q=10 L/h。【Objective】Reveal the influence of different drip head flow rate on soil moisture distribution characteristics,balsam pear tree growth indexes,to provide theoretical reference for the screening of local balsam pear drip irrigation selection of the best drip head flow rate.【Methods】Taking 5-year-old Korla balsam pear as the experimental object,through setting different drip head flow rate,the horizontal and vertical soil moisture transport characteristics were studied under drip head flow rate and the influence on the changes of balsam pear new shoot length,thickness,leaf photosynthetic characteristics,fruit longitudinal and transverse diameter,single fruit weight.【Results】The soil moisture transport characteristics and root distribution to achieve a high degree of coincidence when the drop flow rate was 10L/h,and it had obvious promoting effect on the growth of pear.【Conclusion】The optimal drip head flow rate is q=10L/h.
