众所周知,发生裂果是果树生产上存在的一个普遍问题,如葡萄、枇杷、樱桃、苹果、荔枝等,在不良的外界环境条件或不当的栽培技术下,均会发生裂果,通常裂果率可达14—30％,严重时可达60—70％,果实一旦发生裂果,不仅影响外观品质,而且还能引起病原菌的入侵,造成果实腐烂变质,给生产上带来巨大的经济损失。 It is well-known that cracking is a common problem in the production of fruit trees, such as grapes, loquat, cherry, apple and lychee. Cracking occurs under adverse environmental conditions or improper cultivation techniques. -30% in severe cases, up to 60-70% in severe cases. Once the fruit is cracked, it not only affects the appearance quality, but also causes the invasion of pathogenic bacteria, causing the fruit to rot and deteriorate, bringing huge economic losses to production.
