据观察,柑桔绝大部分的花在开花期和果实发育过程中脱落,其花、果比率相当低,座果率一般仅1～5%左右。因此,栽培上应采取措施,在减少无效花量的同时,在植株可能负担的范围内,减少生理落果,增加着果率,则可明显提高产量。为减少生理落果,可采取以下技术措施: It is observed that the vast majority of citrus flowers during the flowering and fruit development off, the flower and fruit ratio is very low, fruit set rate is generally only about 1 to 5%. Therefore, measures should be taken in cultivation, while reducing the amount of inefficient flowers, while reducing the physiological fruit drop and increasing the fruit yield within the range that plants may afford, the yield can be significantly increased. In order to reduce physiological declines, the following technical measures can be taken:
