After bagging apple bag, it is easy to appear micro-cracking and wrinkling. This phenomenon can be divided into two situations: First, the fruit is cracked in the bag. Once the bag is torn off, it is more serious. Second, there is no abnormal phenomenon in the fashion of the bag. Micro-cracking, wrinkled skin, and hair growth occur soon after coloring. Soft and other undesirable phenomena. The main reason is that the temperature in the bag often exceeds 50 degrees during the middle and early stages of apple growth. During normal times, the temperature should be maintained at 35-45 degrees. The first expansion of the fruit is short and the growth is stopped early. Thin and delicate fruit inside, after the bag is torn later, if the water is sufficient, the speed of the fruit's secondary expansion will be faster. Due to the fast fission of the pulp cells, the cell division of the peel cells is slow, and the difference in the internal and external cell divisions results in microcracking of the fruits. Loss of water after micro-cracking of the fruit causes the fruit to shrink and become soft. In addition, calcium deficiency in fruits is also prone to this phenomenon. Measures to prevent wrinkles from bagging apples: 1. After the flowering period, high-temperature and drought-prone conditions can intermittently spray water at the leaves in the evening (before and after the sunset) until it is appropriate for the leaves to drip. In addition, it is better to add 1% potassium dihydrogen phosphate or amino acid calcium to water when spraying water. 2. Spray 2% amino acid calcium aqueous solution during the first and second fruit expansion (good evening spray effect). 3. Naphthalene acetic acid was sprayed once in the early and middle stages of the second expansion of the fruit. 4, should pay attention to picking leaves in the coloring period, transfer fruit.
