摘　　要：[目的]探讨库尔勒香梨有机肥适宜用量,为健康安全果品生产提供理论依据.[方法]设置不同有机肥施用量处理,观测各试验树的生长发育及产量品质.[结果]施用有机肥的库尔勒香梨树与对照相比,新梢平均生长量提高0.40％～ 3.66％,叶面积提高0.77％～1.48％,光合速率提高12.88％ ～23.33％,单株产量提高16.32％ ～ 37.09％,VC含量提高5.28％～14.85％,可溶性固形物含量提高2.03％～3.93％,固酸比提高6.95％～ 9.02％;但有机肥对果形指数和单果重的影响不明显.[结论]有机肥对库尔勒香梨枝叶生长、产量及果实品质等有明显促进作用;60 kg/株施肥量处理下的库尔勒香梨在多项观测指标上表现较好.[ Objective ] In order to provide theory basis of producing health and safety Korla Fragrant Pear, this thesis studied on the appropriate dosage of use organic fertilizer. [ Method ] Some treatments of dif- ferent organic fertilizer level were set, all treatments branch and leaf growth were viewed, and the yield of per plant and fruit quality was observed. [ Result ] It indicated that the new shoots length with each fertilizer treat- ment, compared with no fertilizer treatments, increased by 0.40% -3.66% , leaf area increased by 0.77% - 1.48% , photosynthetic rate increased by 12.88% -23.33%, the yield of per plant increased by 16.32% - 37.09%, vitamin C content increased by 5.28% - 14.85%, soluble solid content increased by 2.03% - 3.93% , and TSS - acid ratio increased by 6.95% - 9.02%. But, we couldn＇t find organic fertilizer treat- ments influence obviously on fruit shape index and single fruit weight. [ Conclusion] To begin with, organic fertilizer could accelerate Korla Fragrant Pear branch and leaf growth and the yield of per plant and fruit quali- ty. In addition, Korla Fragrant Pear used with 60kg/plant fertilizer level is better in all indicators.
