After bagging apple bag, it is easy to appear micro-cracking and wrinkling. This phenomenon is divided into two cases: First, the fruit in the bag on the occurrence of the phenomenon of creases, once the bag is even more serious; second, there is no abnormal phenomenon in the tear bag fashion, to coloring soon after the micro crack, wrinkled skin, Soft and other undesirable phenomena.
The main reason is the high temperature and drought before and during the growth of apple. The temperature in the bag during the day exceeds 50°C. In normal circumstances, the temperature should be maintained at 35°C to 45°C. The first expansion of the fruit is short and the growth is stopped early. Thin and delicate fruit, after the bag is torn later, if the water is sufficient, the speed of the secondary expansion of the fruit 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.
The following measures are taken to prevent bagging of apples from occurring:
After the flowering period, the weather encounters high temperature and drought. The water can be sprayed to the leaves in the evening (before and after the sunset) intermittently until the leaves are suitable for dripping water. In addition, it is better to add 1% potassium dihydrogen phosphate or amino acid calcium to water when spraying water.
A 2% solution of amino acid calcium was sprayed during the first and second fruit enlargement (good evening spray).
Naphthalene acetic acid was sprayed once in the early and middle stages of the second expansion of the fruit.
Pay attention to picking leaves and turning fruit during the coloring period.
We have Oxytocin Injection and Cloprostenol Sodium Injection solve animals' parturition problems. Oxytocin Injection stimulates the uterus and strengthens the contraction of the uterine smooth muscle. Cloprostenol Sodium Injection subsides corpus luteum and stimulates uterine smooth muscle contraction and cervical relaxation.
