How to prevent three peppers falling

The "three falls" of peppers occur under different cultivation conditions. In the early stage, the buds are shed, and some defoliation and fruit drop occur in the middle and later stages, which results in a significant reduction in yield. There are two reasons for the “three downfalls”. First, they are physiological. They include the temperature during the growing period when the seeds are planted too early or in the back-season, especially when the ground temperature is lower than 18°C, and the physiological function of the roots is decreased, 8°C. When the roots stop growing, plant growth stagnates, and the temperature is lower than 15°C. Although flowering can take place, the anther cannot be powdered, resulting in falling flowers. During the growing season, the temperature is too high, over 35 °C, may be fertilized after flowering, or the ground temperature exceeds 30 °C, and the development of the root system is impaired, resulting in poor development of pollen, which causes flowering. During the growing period, it encounters continuous and cloudy rain for a long period of time. The lack of light, excessive water content, plant lengthiness, and dysregulation of reproductive growth cause "three falls." Second, due to pathological reasons, during the growing period of pepper, it was infected with sores, anthrax, and viral diseases that caused "three falls."

Prevention:

For the “three falls” of peppers that occur in the growing season, the main causes of the disease must first be identified. These are physiological reasons, such as high temperatures, low temperatures, excessive water, plant length, drought, etc., which must be controlled through strengthened management. Seriously exposed to open-chili pepper, it is necessary to remove water in a timely manner to prevent damage. In the event of a drought causing fallen flowers and fallen leaves, timely irrigation should be added to ensure the normal growth of plants. If the density is too high and the light is insufficient, the density should be adjusted, the weak strains should be removed, and the plants should be densely planted to facilitate ventilation. For pathological reasons, the type of the disease should be determined according to the symptoms of the disease, and the degree of the disease should be ascertained in order to prevent and treat the disease.
