Reasonable dense planting
Precocious eggplant varieties are suitable for 3500-4000 strains per mu. When the plants grow too dense, the side branches below the first branch must be removed, the old leaves and diseased leaves should be removed, and the pruning should be timely in order to adjust the plant structure. ,
Temperature and humidity adjustment
Temperature control: Daytime temperature control in 25 °C ~ 28 °C, more than 30 °C should be promptly ventilated, night temperature control in 16 °C ~ 17 °C. Daytime flowering temperature control in 25 °C ~ 30 °C, night control in 15 °C ~ 17 °C.
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 vent moisture in time to avoid flooding.
Fertilizer management
Eggplant early watering to control the main, less watering, more loose soil, especially the water during the flowering of the gate tomato can not be too much, otherwise, it is easy to drop flowers and fruits. When the door grows to the size of the walnut, topdressing, watering, topdressing 10 kg of urea per acre. At the same time pay attention to the application of phosphorus and potassium fertilizers. When watering, in order to prevent the early ground temperature drop, sunny morning watering and watering the gutter can be adopted.
Growth management
Vegetative overgrowth: timely timely seedlings, seedlings, appropriate water control fertilizers, cultivating loose soil, so that nutrient growth in time to reproductive growth.
The plant growth is too weak: strong seedlings should be selected when planting, and fertilization materials should be added at the same time to promote root growth and strong growth.
Insufficient light: 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. 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.
