为了提高荔枝产量 ,研究了海南省儋州市妃子笑荔枝果实生长发育和座果规律。试验结果表明 ,在海南儋州 ,妃子笑荔枝从谢花后到果实成熟需要历经 60多d ;在花后一个月内是果实增长最快时期 ,一个月后增长速度减缓 ;果实发育的落果高峰在果实纵径 1 0cm以前 ,当果实纵径超过 1 0cm时 ,落果明显减少 In order to improve the yield of litchi, the fruit growth and the fruit setting pattern of litchi in Feizixiao of Pizhou City, Hainan Province were studied. The results show that in Danzhou, Feizixiao litchi needs more than 60 d after the flower from Xiehua to maturity; within one month after anthesis, it is the fastest growing period of fruit, and the growth rate slows down after one month; the peak of falling fruit development In the fruit longitudinal diameter 10cm ago, when the fruit length more than 10cm, fruit drop significantly reduced
