通过对库尔勒香梨(简称香梨)不同序数、同一花序不同序位以及花期气温对座果率影响的调查分析,发现香梨的同一花序随着序位的升高座果率逐渐下降。在对香梨疏花时,初果期的幼树留取花序基部1,2,3序位的花朵,结果盛期的成年树序数少的花序保留基部1,2,3序位的花朵,序数多的留取基部1~4序位或1~5序位的花朵为最佳留花位置。
Through the investigation and analysis of the different ordinal numbers of Korla fragrant pear (Pear), the different inflorescences of the same inflorescence and the effect of the flowering temperature on the fruit set rate, it was found that the same inflorescence of the fragrant pear decreased gradually with the increase of the order.
