The main reasons for the occurrence of molting in tomato fruit are the following:

First, pick the leaves too much. To promote excessive coloring of the fruit, the shoulders of the fruit are easily exposed to direct sunlight, and the wounds are heavy and prone to ecdysis.

Second, improper ventilation, resulting in fur skin. Due to the large temperature difference between day and night in the shed, there are many dewdrops on the fruit, and the humidity is very high. When the surface of fruit in the shed is exposed to water for a long time, the sudden change of dry humidity on the surface of the fruit caused by the windproof is severe, and the skin is seriously damaged.

Third, the soil moisture changes greatly. When the soil moisture changes greatly, the growth of the pulp and the growth rate of the pericarp are asymmetric, which can easily cause molting or cracking.

Fourth, the lack of fertilizer. Tomatoes lack boron, calcium and other trace elements, can cause fruit epidermis to become rigid, appear ecdysis.

Control methods:

One, to avoid excessive picking leaves, keep the upper leaves of the fruit not removed.

Second, adjust the ventilation method, first open a small mouth outlet, reduce greenhouse humidity, and then expand the outlet with temperature changes, to avoid dramatic changes in temperature and humidity inside the shed.

Third, watering should be uniform, observe the dry humidity of the soil, to avoid sudden watering of the soil caused by dry soil caused by molting.

4. Spray foliar fertilizer containing boron and calcium (such as agricultural vigor), activate the epidermis, increase the toughness of the peel, and reduce the molting.
