Some days ago, eggplant cracking occurred in some places, affecting the traits of eggplants and being vulnerable to other diseases. What is the problem with eggplant cracking? First, eggplant cracking symptoms The shape of the fruit is not correct, resulting in twin-fruits or cracking. It occurs more often in the protected areas and occurs mainly in the fruit setting stage of the pod in the open field. Cracking sites generally begin at the lower end of the calyx. Second, the cause of cracking 1. In the previous period, the weather was mostly cloudy and the light was relatively weak. In this case, the activity of the root system of the plant is relatively weak, and there is a small amount of cytokinin, which can not guarantee the normal growth of the aboveground part. After the weather is fine, it is watered and fertilized, and the growth rate of the pulp is faster than that of the peel and fruit cracking occurs. 2. The temperature is low or nitrogen fertilizer is used excessively, excessive watering leads to excess nutrients in the growing point, resulting in incomplete flower bud differentiation and development, forming multiple carpels of fruit or stamen base and developing into cracking fruit. 3. Under open cultivation conditions, during the day, high temperature, drought, watering at night, easy to disease, sometimes fruit and leaves friction scars, watering consequences of meat expansion speed, easily lead to cracking. Third, control methods 1. Immerse the seedbed 1 day before planting, plant the eggplant with soil on the second day and try to minimize root damage. After planting, not only can the seedlings be quickened, but also fruiting and fruit malformation can be prevented. 2. After the planting, the use of anti-dropping spray gate tomato flower, can effectively prevent the protective ground or exposed eggplant cracking. 3. The cultivation of eggplants in greenhouses will enter the high temperature season, and the shed film should be gradually uncovered to prevent high temperature hazards or produce malformed flowers. 4. After the weather has turned cloudy, do not immediately apply water to top dressing. A slowly rising process should be given to the ground temperature, otherwise it is not only easy to cause root damage, but also a large number of cracks. Spray cytokinin, Yunda 120, and Harvest No. 1 can be sprayed on the leaves to restore the growth activity of the fruit growing point as soon as possible. 5. Avoid the use of foliar fertilizers with high levels of bentonosteroids after a cloudy or sunny day. Foliar can be supplemented with calcium foliar fertilizer mixed naphthalene acetic acid.
