Eggplant stagnation is a physiological disease of eggplant, which is caused by high temperature, high humidity, lack of light during seedling stage, insufficient water, improper fertilization, and drug effects. The main symptom is that the fruit of the eggplant stops expanding after the fruit is set, and the top surface of the eggplant is sunken, the fruit becomes hard, the food value is lost, or it is barely expanded, but if the stick shape, the hammer shape or the stone shape, the surface luster of the fruit disappears. When the disease is mild, this phenomenon occurs only on the top or one side of the fruit. When the disease is severe, the whole fruit becomes dull, forming “Uchikoâ€, most of the fruit peels are not shiny, there are gaps in the flesh, there is basically no seeds, barely expanded. The seeds in the fruit are also significantly less.
Prevention:
1. Cultivation management should be shaded and cooled in time with shade nets to keep the environment suitable for growing vegetables. To prevent plant growth, shade nets can be removed from 4:00 to 9:00 in the morning, and sprayed with Kaohua No. 3 to suppress the main tip. Prosperous and promote flower bud differentiation;
2. Reasonable irrigation, appropriate water control during the initial period of plant easing to harvesting, and appropriate increase of irrigation volume after harvesting, spraying 800 times of new high fat film to prevent evaporation of water after irrigation.
3, balanced fertilization, timely application of organic fertilizer, nitrogen, phosphorus, potassium fertilizer and trace fertilizer, to do a small amount of each fertilizer, then spray 800 times the new high-fat membrane to improve the utilization of effective pharmaceutical ingredients, and spray in the eggplant bud period Planting Fruit Zhuang Ti Ling enhances the quality of pollen fertilization, increases the rate of fruit set in circulation, promotes fruit development, and makes eggplant produce in succession.
4, pay attention to scientific medication. Eggplants are sensitive to manganese ions and should not use agents containing mancozeb. With the spraying of new high-fat film 800 times liquid to enhance efficacy, improve the utilization of effective pharmaceutical ingredients, consolidate the control effect. It is recommended that vegetable farmers do not apply pesticides 1 to 2 days before harvest, and timely harvesting solanaceous fruit. Harvesting is too late and there are also many pods.
