#New Farmer Creation Contest # First of all, you need to figure out the cause and type of fruit splitting, citrus fruit splitting generally has 3 types, namely wrinkled skin crack, external crack and internal crack.
Wrinkled skin cracks
Hazard characteristics: This type of cracked fruit is the first white skin layer of the peel gradually cracked, the epidermis gradually recessed, the surface looks no different from the normal fruit, only the surface has some irregularly shaped dents, but the middle peel has begun to produce separation, slowly there is a crack, and finally show obvious exocarp cracking.
Cause analysis: Mainly because the fruit in the early stage of growth and development, the supply of nutrients is not sufficient, resulting in some of the development of the peel is damaged, there are some defects, easy to produce wrinkled peel fruit.
External fissure
Hazard characteristics: The peel cuticle of citrus fruit first appears cracked. Then, in order from the outside to the inside, the cells slowly deform, crack, and finally the white cortex completely cracks.
Cause analysis: when the cells of citrus begin to expand or enter the mature stage, encounter drought that lasts for many days, and then there is a catastrophic climate such as heavy rainstorms, the fruit begins to be subjected to drought stress for a long time, in the case of a sharp increase in the water content in the soil, the fruit shows a sharp growth trend, and the peel is slower than the pulp, resulting in the outer peel cracking, with the growth of the fruit, the cracks are getting bigger and bigger, and the middle peel and pulp are cracked.
Internal fissures
Hazard characteristics: The initial part of the crack is the central axis of the fruit, and then gradually expands to the top of the fruit, resulting in the phenomenon of fruit splitting.
Cause analysis: Mainly because the seed is sterilized, the internal gibberellin cannot be produced, and the gibberellin in the peel is relatively high, resulting in inconsistent growth rate and internal cracking.
