【摘要】 【目的】研究不同授粉液施用后大樱桃的坐果率、品质及产量变化，为贵州地区大樱桃高产优质生产提供参考。【方法】以4年生大樱桃品种曙光2号为试验材料，设置不同授粉液处理（处理1,0.2%KH₂PO₄+0.2%H₃BO₃+0.3%白砂糖+2 g花粉液+5 L纯净水+7.5 mL 0.15%高效座果灵；处理2,0.4%KH₂PO₄+0.4%H₃BO₃+0.5%白砂糖+2 g花粉液+5 L纯净水+7.5 mL 0.15%高效座果灵；处理3,5 L清水+2 g花粉液；处理4,CK,自然授粉）,分析不同处理间大樱桃的坐果率、新梢生长量、果实品质和产量差异。【结果】处理1、2、3、4（CK）的坐果率分别为27.17%、27.16%、19.65%和0.87%,新梢生长量分别为68.33 cm、67.81 cm、67.27 cm和68.60 cm;处理1和处理2果实的内在品质与自然授粉无显著差异；处理1和处理2产量分别为1.347 kg/株和1.278 kg/株，较自然授粉分别提升1.297 kg/株和1.228 kg/株。【结论】人工辅助液体授粉能够显著提高大樱桃的坐果率、果实单果重、纵横径和产量，对新梢生长量无显著影响，液体授粉适宜配比为0.2%KH₂PO₄+0.2%H₃BO₃+0.3%白砂糖+2 g花粉液+5 L纯净水+7.5 mL 0.15%高效坐果灵。更多还原

【Abstract】 【Objective】The variation in fruit setting rate, quality and yield of sweet cherry applied with different pollinating solutions are studied to provide a reference for the production of high-yield and good-quality sweet cherry in Guizhou area.【Method】Four pollinating solution treatments are set up, including T₁（0.2% KH₂PO₄+0.2% H₃BO₃+0.3% white sugar+2 g pollen+5 L purified water+7.5 mL 0.15% efficient Zuoguoling）,T₂（0.4%KH₂PO₄+0.4% H₃BO₃+0.5% white sugar+2 g pollen+5 L purified water+7.5 mL 0.15% efficient Zuoguoling）,T₃（5 L clear water+2 g pollen） and T₄（CK, natural pollination）. The variation in fruit setting rate, new shoot growth, fruit yield and quality of 4-year sweet cheery cultivar Shuguang 2 under different treatments are analyzed.【Result】The fruit setting rate and new shoot growth of Shuguang 2 under T₁, T₂,T₃ and T₄ treatment are 27.17%,27.16%,19.65% and 0.87%, and 68.33 cm, 67.81 cm, 67.27 cm and 68.60 cm respectively. There is no obvious difference in intrinsic quality of fruit among T₁, T₂ and T₄ treatment. The yield of Shuguang 2 under T₁ and T₂ treatment are 1.347 kg/plant and 1.278 kg/plant, increased by 1.297 kg/plant and 1.228 kg/plant compared with that of T₄ treatment.【Conclusion】Artificial assisted liquid pollination treatment can improve the fruit setting rate, single fruit weight, longitudinal diameter, transverse diameter and yield of sweet cherry significantly, but has no significant effect on new shoot growth.The suitable proportion of liquid pollination is 0.2% KH₂PO₄+0.2% H₃BO₃+0.3% white sugar+2 g pollen+5 L purified water+7.5 mL 0.15% efficient Zuoguoling.更多还原
