How to do the cracking of the eggplant in the greenhouse?
Eggplant rotten fruit is a kind of disease that occurs on eggplant. It is mainly caused by partial decay and fruit rot or fruit loss on the fruit. The eggplant loses its commodity value, causing serious economic losses, and it is difficult to control.
The main reason for eggplant cracking:
First, the flower buds are poorly differentiated. In the process of eggplant production, if the greenhouse temperature is low, it will lead to poor flower bud differentiation, especially at night, the temperature is low, and the deformed flowers of multi-ventricle are easily differentiated. The fruits developed by the deformed flowers are mostly deformed fruits, and the deformed fruit often shows the top. Cracking phenomenon.
The second is the improper use of hormones. The use of hormones in eggplant is mainly to improve the ability to sit fruit. The best use time is to use it on the flowering day. The fruit will appear in the early stage, and the fruit will be cracked too late. When the hormone concentration is too high, it will also cause fruit cracking.
The third is uneven floods and floods. In the process of eggplant production, farmers often control the watering to prevent the humidity in the greenhouse, and often control the watering. When the soil is too dry, the growth of the skin is blocked, and the growth of the pulp is slow. If the water is suddenly watered, the water supply of the plant is sufficient, and the growth speed of the pulp is greater than that of the peel. At the speed of growth, cracking will occur.
Fourth, the temperature difference between day and night is large. In the production process of eggplant, if the temperature is high during the daytime and the nighttime does not pay attention to the protection, the temperature is low, and it is affected by the thermal expansion and contraction. When the temperature is low at night, the shrinkage speed of the eggplant peel is greater than the shrinkage speed of the pulp, so that the skin pulp can not be synchronized. , there will be cracking.
Control method:
1, the optimum temperature of eggplant is 15 ~ 30 ° C, to avoid the greenhouse temperature is too high or too low, the rational use of hormones to avoid the use of improper use of hormones caused by eggplant cracking.
2, reasonable watering, to avoid over-drying, increase warmth measures, to avoid excessive temperature difference, reduce the phenomenon of cracking.
3. Spray the boron-calcium foliar fertilizer to enhance the toughness of the peel and avoid cracking.
