果实裂果是果树生产上的一个普遍问题,如枇把、葡萄、樱桃、苹果等,均易发生裂果,一般裂果率为15—30％,严重时可达60—70％。 一、裂果原因 1.气候条件不良。在果实膨大成熟期,如遇长期阴雨、光照不足,或久旱突然降雨时,极易发生裂果。原因是降雨会使果皮大量吸收水分,产生异常的膨压,引起机械伤害,导致裂果。
Fruit cracking fruit is a common problem in the production of fruit trees, such as loquat, grape, cherry, apples, are prone to cracking, the general rate of 15-30% fruit cracking, severe up to 60-70%. First, the reasons for cracking 1. Poor weather conditions. Expansion of the fruit maturity, in case of long-term overcast, inadequate lighting, or a sudden drought rain, prone to cracking. The reason is that the rain will make the peel absorb a large amount of water, resulting in abnormal turgor pressure, causing mechanical damage, leading to cracking.
