摘要(Abstract)：

【目的】比较不同防冻防寒措施对枇杷结果及其投入产出比的影响,为枇杷优质高效配套栽培技术提供理论依据。【方法】以‘黔星’枇杷为试材,比较防寒布、食品袋+网套、无纺布、遮阳布、防冻药物、钢架大棚、拱杆薄膜不同防冻措施下枇杷坐果率、有效穗、冻害情况、果实大小及产量,并测定果实品质主要指标。【结果】拱杆薄膜防冻处理下坐果率、有效穗数、单穗果量、单位面积产值及投入产出比显著高于其他处理;各防冻处理对果形指数没有显著的影响;防冻药物处理下平均单果质量显著高于其他处理;钢架大棚和拱杆薄膜处理下可溶性固形物及总糖含量显著高于其他处理;防寒布处理下维生素C含量显著高于其他处理;遮阳布处理下可滴定酸含量最高;此外,拱杆骨架聚乙烯薄膜覆盖树冠对树体不同位置防冻效果较其他处理显著。【结论】与常规栽培相比,各防冻措施对枇杷结果均有不同程度的积极影响。综合评价,拱杆聚乙烯薄膜覆盖树冠处理防冻效果最佳。
