What about the eggplant falling from the greenhouse

There are many reasons for eggplant falling flowers, such as excessive vegetative growth, weak plant growth, too dry or too high humidity, high temperature or lack of light. The prevention and control measures of vegetative growth are as follows: squatting seedlings at the right time, properly controlling water and fertilizer during the squatting stage, ploughing and loosening the soil, and timely spraying Chuhuawang No. 3 to return the exuberant essence of the top and shoot of the plant branches. turn to saturated supply of fruit reproductive development to transfer vegetative growth to reproductive growth in time. Prevention and control measures of weak plant growth: strong seedlings should be selected during planting, and fertilizers should be added at the same time to promote roots and seedlings. After transplanting, spraying new high-fat film can effectively prevent aboveground water from evaporation, seedling water from transpiration, isolation from diseases and insect pests, shorten slow seedling period, quickly adapt to the new environment and grow healthily. According to the plant growth, the management of flower thinning and fruit restriction was carried out. Prevention and control measures of lack of light: increase the time of light and the amount of light. The grass curtain should be uncovered early and late in sunny days to prolong the lighting time, and the curtain should also be opened to absorb scattered light on cloudy days and shorten the opening time on rainy days. Timely foliar spraying of new high-fat membrane can prevent leaf virus infection, make branches and leaves green and luxuriant, and enhance the accumulation and directional transport ability of photosynthetic products. You can also take measures such as hanging on the back wall, laying reflective screens on the ground, and replenishing light with fluorescent lamps at night to increase illumination. Temperature control: during flowering, the daytime temperature is controlled at 25-30 ℃, and the night temperature is reduced to 15-17 ℃. Humidity control: the air humidity is generally about 80%. When dry, water and salt should be irrigated in time to keep the soil moist. When the humidity is too high, ventilation and dehumidification should be done in time to avoid flooding irrigation to increase humidity.
