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。
Abstract
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.Arti-ficial 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.
