What is the reason for the flowering of citrus fruit surface in the later stage?
The main reason of orange fruit cracking is that the fruit is swollen and there is too much water in heavy rain. Because the water absorption of pulp is obviously greater than that of fruit epidermis, the epidermis is cracked. If there is a long drought in the early stage and then it suddenly rains heavily, the fruit cracking will be more serious. According to this reason, the phenomenon of fruit cracking can be reduced by reducing the ground water content.

At present, some orchards began to lay silver reflective films on the ground of orange orchards in late August, and achieved quite good results. On the one hand, it can reduce the humidity of the ground soil, on the other hand, it can reflect the sunlight, making the surface color of the fruit more uniform, thus improving the commodity value. Of course, measures such as paying attention to digging drainage ditches and keeping drainage unblocked will also have a certain effect on reducing fruit cracking.
