There are many reasons for falling eggplants, such as excessive vegetative growth, weak plant growth, excessive dryness or humidity, and excessive temperature or light.
Control measures for overgrowth of nutrients: timely seedlings of seedlings, proper control of water and fertilizers during seedling stage, cultivating loose soil, timely spraying of Huawang No. 3, so that the top of the shoots will flourish, and the nutrient will flow back towards the saturation supply of fruit. Development transfers nutrient growth to reproductive growth in time.
The measures for prevention and control of plant growth are too weak: When planting, strong seedlings should be selected, and fertilization materials should be added at the same time to promote root growth. After the seedlings are transplanted, spraying a new high-fat membrane can effectively prevent the ground water from evaporating and the seedling water from transpiration. Isolation of pests and diseases will shorten the period of seedling sowing, quickly adapt to the new environment, and grow healthily. According to the growth condition of the plants, the management of flowering and fruit limiting is implemented.
Illumination prevention measures: Increase lighting time and lighting. As early as the sunny days, the straw curtains cover the late cover and extend the lighting time. On cloudy days, it is also necessary to expose the screen to absorb scattered light, and rainy days reduce the time for curtain opening. Timely spraying of new high-fat membranes on leaves can prevent virus infection in leaves and make the foliage green and lush, photosynthetic product accumulation and directional transport ability enhanced. You can also use the rear wall suspension, laying the light curtain on the ground, and use the fluorescent lamp to fill the light at night to increase the light.
Temperature control: During the flowering period, the temperature is controlled at 25-30°C during the day and the temperature is reduced to 15-17°C during the night.
Humidity control: The air humidity is generally about 80%, and when it is dry, it should be filled with salt in time to keep the soil moist. When the humidity is too high, it is necessary to ventilate and drain moisture in time to avoid flooding and flooding to increase the humidity.
