There are many reasons for planting peppers and falling flowers in greenhouses, but in combination, they are mainly caused by malnutrition, unfavorable climatic conditions and pests. 1. Malnutrition Due to unfavorable cultivation and management measures, such as excessive planting density or excessive application of nitrogen fertilizer, the plants are prolonged, the vegetative growth and reproductive growth are out of balance, and the pepper flowers and fruits are insufficiently nutritious and fall off. In greenhouse cultivation, peppers are easier to grow, so falling flowers and fruit are common phenomena. 2. Unfamiliar climatic conditions In winter and spring, greenhouses often encounter insufficient light, and the temperature is low, which affects pollination. Even if pollination, the fruit is also poorly developed and easy to fall off. This is more prominent in rainy and snowy weather. Poor ventilation in the greenhouse, when the humidity is too large, the pepper flowers can not be properly powdered, making it difficult to complete pollination and fertilization, resulting in falling flowers and fruit. If the diseased pests are harmful to the pepper, such as virus disease, anthracnose, leaf blight, etc., it is also easy to cause falling flowers and fruit. Such as the infection of the virus, often appear dead roof phenomenon, causing falling flowers and fruit; tobacco budworm, cotton bollworm fruit, is also easy to cause fruit loss. Prevention of falling flowers and fruit should start from strengthening cultivation management, mainly to cultivate strong seedlings, timely planting, rational close planting and scientific fertilization. After planting, the ventilation and dehumidification are strengthened. The daytime temperature in the shed is maintained at 25-28 °C, the nighttime is 15-18 °C, and the flowering period is at least 15 °C. In the grid, it is recommended to fill the water under the membrane, and not to flood the water. Through the scientific rhyme cultivation management, improve the plant's resistance to stress, pay attention to pests and diseases. In addition to the above measures, 40 to 50 ppm of tomato spirit, 50 ppm of acetic acid spray, dip flower, or 20 to 30 ppm of 2.4-D can be used to spread the flower handle.
