How to reduce the falling of pepper
There are many reasons for the planting of peppers in greenhouses, but they are mainly caused by poor vegetative growth, adverse climate conditions, and pest and disease damage. 1. Nutritional malnutrition: due to unfavorable cultivation and management measures, such as excessive planting density or excessive nitrogen fertilizer application, resulting in plant lengthiness, loss of balance in vegetative growth and reproductive growth, and loss of pepper and fruit nutrition. 2. The impact of adverse weather conditions: In winter and spring greenhouses often encounter insufficient light, low temperature weather, affect pollination, even pollination, the fruit is also stunted, easy to fall off, which is more prominent in cloudy and rainy weather. Poorly ventilated greenhouses, when the humidity is too large, resulting in pepper powder can not be normal, so that fertilization is difficult to complete fertilization caused by falling flowers. 3. Diseases and pests: Viruses, anthracnose, leaf blight, etc. may also occur in peppers, which can easily cause flowering and fruit drop. Infected with viral diseases, often appear dead phenomenon, resulting in falling fruit; fruit of tobacco budworm, cotton bollworm, but also easily lead to fruit shedding. Preventing the falling of the peppers should start with strengthening the cultivation and management, mainly to cultivate strong seedlings, timely planting, rational close planting, and scientific fertilization. After the planting, the ventilation and humidity were enhanced. The temperature in the shed was maintained at 25-28°C during the day, 15-18°C at night, and the minimum flowering period was 15°C. The shed promotes irrigation under the membrane. Do not flood the reservoir. In addition to the above measures, the flower stalk can be painted with 40-50 ppm of tomato spirit, 50 ppm of nitric acid spray, dip flower, or 20-30 ppm of 2,4-D.
