我国枇杷产区经常发生枇杷裂果,福建省每年因此而损失20多万元。1981～1983年,福建省农科院果树所在莆田县枇杷园,于果实退绿期(果实由青绿转淡绿,约在成熟前1个月)的晴天,喷布1500ppm 乙烯利加3000倍骨胶(以喷果实为主),对防止枇杷裂果取得了良好效果。处理树裂果率仅1.51～10.34%,不喷的为18.72～35.5%。单果重 Loquat loquat cracking occurs frequently in China’s loquat producing areas, resulting in the loss of more than 200,000 yuan each year in Fujian Province. From 1981 to 1983, the Loquat Garden of Putian County, where Fujian Provincial Academy of Agricultural Sciences fruit trees were located, was sprayed with 1500ppm ethylene plus 3000 times of glue on the sunny days of the fruit returning green stage (the fruit turned from green to green, about 1 month before maturity) To spray fruit-based), to prevent cracking loquat fruit has achieved good results. The rate of split tree fruit was only 1.51 ~ 10.34%, 18.72 ~ 35.5% did not spray. Fruit weight
