摘　　要：本试验采用多种化学药剂组合和不同使用方法对巨峰葡萄保花保果效应进行了研究。结果表明, 无论哪种使用方法,凡是用了化学药剂和植物激素的处理均有提高坐果率的效果。综合葡萄果实质量指标, 得出用NaHSO3(100mg/L)+B9(2000 mg/L)在初花期和盏花期各喷一次,并用CPPU+GA3 20mg/L在谢花后一个星期内浸果的保花保果效果为最佳。The experiment studied the effect of preserving flower and friut in kyoho by using a few chemicals. The results showed that all the treatments which applied chemicals or hormones could raise the percentage of setting fruit whichever application method. Quality index of grape from treatments were analysed that the best treatment was that the vines were sprayed twice （the treat period was at early bloom and full bloom respectively） with NaHSO3 （ 100mg/L ） ＋B9 （ 2000 mg/L ） and then the clusters were immersed with CPPU＋GA3 20mg/L （the treat period was a week after the flower had withered）.
