Preliminary Study on The Control Method of Prunus Americanc Fruit Cracking

From 2018 to 2019, the control methods of Prunus americanc fruit were tested with Prunus americanc as experimental material. The fruit cracking rate of fruit trees was reduced by using comprehensive technical measures such as orchard grass, plastic film mulching, spraying gibberellin and spraying calcium fertilizer. The results showed that all treatments could reduce the fruit cracking rate of American plum fruit, and the effect of spraying gibberellin was the best.
