摘　　要：[目的]通过人工授粉措施来提高核桃的坐果率和果枝率。[方法]选取阿克苏地区主栽的2个核桃品种,进行人工授粉(抖授法)和自然授粉2种处理,连续3年观察2个品种的物候期,统计其坐果率和果枝率。[结果]人工授粉处理后,温185和新新2号的坐果率比自然授粉处理分别提高22百分点和18百分点,明显提高了温185和新新2号的内膛果枝率。[结论]温185、新新2号人工授粉的最佳时间在每年的4月底;人工授粉很大程度地提高了坐果率和内膛果枝率。[Objective]To increase the fruit-bearing rate and fruiting branch rate of walnut by artificial pollination measures. [Method]The main cultivars of walnut in Aksu Area were selected,artificial pollination and natural pollination were separately treated on them. Phenological period of two cultivars were continuously observed for three years,fruit-bearing rate and fruiting-branch rate were recorded. [Result]The results showed that fruit-bearing rates of Wen185 and Xinxin 2 after artificial pollination were higher than that of natural pollination,respectively. Artificial pollination significantly increased their inner fruiting-branch rate. [Conclusion]The artificial pollination period of Wen185 and Xinxin 2 is best in the end of April each year. Artificial pollination greatly improves the fruit-bearing rate and inner fruiting-branch rate.
