Yes Cracks and cracks will appear more or less in the hard core stage and expansion stage of fruits. In particular, some varieties, such as flat peach and nectarine series, are more prone to fruit cracking.

1. If the fruit does have drought during the expansion period, it must be replenished in time. If the drought is too severe, skin cells will age. After heavy rain and flood, the water content in the soil will change rapidly, and the cell wall of the epidermis will rupture when it expands with water, and the fruit will not develop synchronously but naturally crack. The easiest way is to water alternately. Generally, conventional irrigation can reach 30 cubic meters per mu, and alternate irrigation is only 15 cubic meters, which will not cause excessive root pressure to absorb water, expand and crack fruit. This is called balanced water supply.

2.

There is also a phenomenon of fruit cracking, that is, not watering or not watering for a long time. Fruit cracking will occur when it rains lightly or moderately, and this kind of cracking is even greater. Because fruit pores can also absorb water. So the cracks and cracks caused by rain are the most.

3. Peaches have too much water content, and they are easy to crack when exposed to the sun or the temperature difference between day and night is large.

Most of them occur in the mature period of peach fruit, some of them crack longitudinally from the top of the fruit to the stalk, and some of them crack irregularly at the top of the fruit, which reduces the commodity value and is easy to rot. The sudden and violent change of air pressure causes the pulp to swell and the peel to break.
