本试验用中华蜜蜂(Apis cerana Fab.)为糯米糍荔枝品种作授粉试验.结果表明,网内强化蜜蜂授粉处理和蜜蜂自由授粉处理的座果数分别比网内隔离无蜂授粉处理的座果数提高2.48倍和2.9倍.本文认为蜜蜂能提高荔枝座果数的主要原因有二:一是促进荔枝不同品种间的异花授粉,大大提高受精率;二是蜜蜂进行采集活动时,能对凋谢花枝作清理,为荔枝的小果发育创造良好条件,促进座果,减少生理落果现象.因此,组织蜂群在荔枝花期进行自由授粉,是提高荔枝产量的重要途径之一.
In this experiment, we used Apis cerana Fab. To pollinate glutinous rice litchi varieties.The results showed that the net fruit number of bee pollination and bees pollination were respectively less than those of the net without pollination The number increased by 2.48 times and 2.9 times.This paper believes that bees can improve the number of litchi fruit for two main reasons: First, to promote cross-pollination between different varieties of litchi, greatly enhance the fertilization rate; second, bee collecting activities, Withered flower branches for cleaning, to create good conditions for the development of small fruit litchi and promote fruit, reduce the phenomenon of physiological fruit drop.Therefore, the organization of bees in the litchi flowering free pollination is to improve litchi yield one of the important ways.
