Malformed fruit is one of the most common problems in the process of planting sweet peppers. The main manifestation is abnormal fruit growth. Malformed fruit is a physiological disease, mainly due to bad weather conditions encountered during flower bud differentiation or flowering in bell peppers, such as too high or too low temperatures, poor flower bud differentiation of sweet peppers, or poor flower fertilization of bell peppers. Or is it not originally developed completely.
1, pay attention to temperature control: autumn in the bell pepper flowering fruit set, the temperature should not be too high. If the temperature in the greenhouse exceeds 35 °C or 32 °C for more than 2 hours, pollen or poor fertilization occurs. Before and after the Spring Festival, care should be taken to avoid the temperature and the ground temperature in the greenhouse, which will affect the sweet peppers and fruit set. The application of biological fertilizer can promote normal fruit setting before and after the Spring Festival.
2, pay attention to supplement fertilizer: sweet pepper lack of boron, calcium and other elements will lead to deformed fruit, so always pay attention to spraying with boron, calcium and other elements of the foliar fertilizer or nutrient balance, such as foliar spraying green Fenwei 3 and boric acid Wait. Reduce the amount of nitrogen fertilizer application, increase the amount of potassium fertilizer, such as potassium dihydrogen phosphate, potassium sulfate, etc., timely spraying shellfish nutrient balance agent is conducive to fruit set.
3, pay attention to control the growth of plants: plants grow too prosperous, the chance of malformed fruit will increase, you can spray growth regulators or pruning, etc. to ensure the normal growth of sweet pepper fruit. If sweet peppers do not stand fruit, it may lead to overgrowth of the plants, which can be sprayed with booster and regulate the temperature to ensure the normal growth of the plants, in order to facilitate fruit growth.
