The results show that the average blooming days of each panicle is 12.9 d; The proportion of female and male flowers is 1：6.57; The temperature during the pollination and fertilization period is between 25℃~36℃, under the higher temperature conditions the fruit set rate is 27.6%, the female flower drop and the young fruit drop accounted for 11.1% and 61.3% of the total number of female flower respectively. The flower-visiting insects consist of 21 kinds from 5 orders and 13 families, among them Cetoniidae is the most one and occupying 33.4%。
