There are six reasons for fruit and vegetable cracking:
The reason fruits and vegetables a cracking: cracking caused by physiological characteristics of species Linyi fertilizer Copyright
The cracked fruit is closely related to the physiological characteristics and genetic characteristics of the variety. The fruit size, peel thickness, fruit water content, cell tightness, fertilizer requirement, sugar content, acid content and fruit development quality all affect the fruit cracking. . For example, in the grape varieties, the varieties with thin peel and crispy flesh are easy to crack, and the varieties with fast water absorption and high water absorption during the coloring period are prone to cracking; the pomelo, the larger the fruit shape index, the thicker the fruit top, the center of the heart. The more enriched, the lighter the cracked fruit; the nectarine variety, the sugar content is higher, the cracked fruit of the variety with lower acid content is heavier; the melon, watermelon variety, the thin and crispy variety of cracked fruit are heavier.

The cause of fruit and vegetable cracking fruit 2: plant endogenous hormone imbalance caused by cracked fruit Linyi fertilizer net copyright
Changes in the proportion of endogenous hormones in plants affect the rate at which the skin and flesh grow. When the growth rate of the two is unbalanced, cracks are formed. In actual production, in the middle and late stages of fruit development, the phenomenon of cracking caused by hormone imbalance is more common. At the same time, the abuse of hormonal plant growth regulators is one of the causes of cracking. Linyi Fertilizer Network Copyright
Fruit cracking three reasons: soil moisture caused dramatic changes in cracking Linyi fertilizer Copyright
The change of soil moisture has a great influence on the absorption of calcium in the pericarp. Drought and flooding may cause water stress, reduce the absorption of calcium, and then cause cracking. In the early stage of crop growth, when drought occurs, during the rapid expansion of the fruit, frequent rainfall occurs. The water transported by the roots to the fruit increases rapidly, and the flesh cells will expand rapidly. At this time, the pericarp has been aging, and the pericarp cells are swollen due to the restriction of the stratum corneum. There will be a case where the flesh swells the peel. The cracking fruit appearing in this situation is more common in grapes, dates and pomegranates. If the water shortage in the early stage will affect the expansion of young fruit, in the case of continuous rainfall or flooding in the coloring period, a large number of cracking fruits will occur.

Four reasons for cracking of fruits and vegetables: pest damage caused by cracking Linyi fertilizer Copyright
Studies have shown that anthracnose can cause umbilical orange cracking, anthracnose, rust tick, red spider, etc. are directly related to fruit cracking, and attention should be paid to the prevention and control of pests and diseases. Powdery mildew is the result of skin hardening and loss of elasticity. After the hard core period, it is easy to split from the top of the fruit and form a cracked fruit. After the red spider is harmed to the grape, the fruit surface forms brown rust spots, and most of them form a cracked fruit from the fruit ridge. Linyi Fertilizer Network Copyright
Five reasons for cracking of fruits and vegetables: nutritional imbalance caused cracking Linyi fertilizer Copyright
The mineral elements and nutrient balance in the flesh have a significant effect on the cracked fruit, and the nutrient imbalance in the tree will aggravate the fruit cracking. Phosphorus, potassium and calcium have the greatest influence on fruit cracking during fruit growth, followed by magnesium, boron, zinc, iron, copper and manganese. When one or several elements are excessive and the other elements are low, the cracking will increase. In actual production, in the later stage of crop growth, fruit cracking is very common due to calcium deficiency and potassium excess. At present, the problem of soil acidification is becoming more and more prominent, and the lack or imbalance of medium and trace elements caused by this phenomenon is very common, which aggravates the degree of cracking.

Reasons for fruit and vegetable cracking fruit 6: Cultivation and management measures cause cracking fruit Linyi Fertilizer Network Copyright
The fruit trees with weak tree, poor illumination, poor ventilation and partial application of nitrogen fertilizer have serious fruit cracking; fruit and vegetables with small load and leaf are easy to induce fruit cracking; soils with poor drainage, severe compaction, poor permeability and soil acidification have serious fruit cracking; The fruit orchard cracking fruit with poor pest control is more serious; the amount of fruit cracking in the orchard using a large amount of ethephon and gibberellin increased significantly.

In summary, the reasons for the cracking are multi-faceted. The solution to the problem should also consider a variety of factors. It is often difficult to achieve a good result by unilaterally emphasizing a certain factor. It is necessary to summarize the more mature integrated anti-fracture management schemes, which involve the control of soil pH and comprehensive nutrient content, water management, pest control and the use of growth regulators to achieve anti-cracking purposes.
