Prevention measures against falling flowers in greenhouses
There are many reasons for falling eggplants, such as excessive vegetative growth, weak plant growth, excessive humidity or excessive humidity, and excessive temperature or light. It is recommended that vegetable farmers determine the cause of falling flowers based on the actual conditions of last year's greenhouses, and then take relative measures to prevent the occurrence of eggplant falling again this year.
Control measures for overgrowth of nutrients: timely seedlings for seedlings, appropriate water control fertilizers for seedlings, cultivating tillage, and timely transfer of nutrient growth to reproductive growth.
The measures for prevention and control of plant growth are too weak: strong seedlings should be selected at the time of planting, and fertilization materials should be added at the same time to promote root growth. According to the growth condition of the plants, the management of thinning flower limiting fruits should be 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. 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 during the day is controlled between 25°C and 30°C, and the nighttime temperature is reduced to 15°C to 17°C.
Humidity control: The air humidity is generally around 80%. When dry, it should be timely watered 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.
