摘　　要：以6a生"徐香"猕猴桃为试材,设剪留花柱0(CK1)、1、2、3、4、5、8、11、14、17、22、27、32、37和全留(CK2)共15个处理,花后1个月调查坐果率、收获后测单果重和果形指数。结果表明:全部减去花柱,坐果率为0%,授粉柱头小于等于11,坐果率在25%～83%;大于等于11时,各处理坐果率为83%～87%,与对照全部柱头授粉坐果率无明显差异;在授粉柱头1～11范围内随数量增加,其单果重由13.6g增至64.3g。当授粉柱头大于等于14时,单果重在74.9～83.4g,与对照80.0g无明显差异;授粉柱头在1～8时,果形指数在0.77～1.01之间,明显低于对照。当授粉柱头大于等于11时,果形指数在1.05～1.19,与对照1.16无明显差异。从坐果率、单果重、果形指数3项影响产量商品性的指标看,"徐香"充分授粉的数量指标为11～14,表明生产上可以此为依据,减少花粉使用量,降低成本,提高效率。Taking 6 years old ＇Xuxiang＇ kiwi as materials, setting 15 cutting style treatments that were subtracting all the styles（CK1）,keeping 1,2,3,4,5,8, tl, 14,17,22,27,32,37 styles and all keep（CK2）, fruit setting rate was investigated after flowering, sigle fruit weight and fruit shape were investigated after harvest. The results showed that the subtracting all the styles,the fruit setting rate was 0%, pollination stigma less than or equal to 11, the fruit setting rate at 25- 83 % ;greater than or equal to 11, the processing rate of fruit were 83 % -87 % no significant difference in control all the stigma pollinations fruit weight in the 1-11 range with pollination style increased in the number of its weight increased from 13. 6 g to 64. 3 g. When the pollinated stigma was greater than or equal to 14,fruit weight between 74. 9-83. 4 g, no significant difference with control 80.0 g; pollination stigma between 1-8, fruit shape index was 0. 77 -1.01, significantly lower than the control. Pollination stigma was greater than or equal to 11 ,fruit shape index between 1.05- 1.19,no significant difference with control 1. 16. From the above three indicators affect the yield of merchantability, ＇Xuxiang＇artifieial full pollination quantitative indicators to 11-14, and the results that may use this as the basis for production,reduce the amount of pollen use,reduce costs.
