How to promote the continuous fruit setting of sweet pepper:
1. Don't rely on the flower to promote fruit. Because the head 茬 sweet pepper has less fruit, some farmers use a little anther to promote the fruit setting. As a result, the sweet pepper is fruit-bearing, but the deformed fruit is more. Sweet pepper is a self-pollinating crop. As long as the environmental conditions are suitable, you can take your own fruit without a little flower. Therefore, the bell pepper can be promoted by temperature regulation. The suitable temperature for the sweet pepper flowering period is between 25 ° C and 28 ° C, and the temperature difference between day and night is between 10 ° C and 12 ° C. If the night temperature is too high and the temperature difference between day and night is too small, it is not easy to take fruit. This requires ventilation, shading and other measures to control the temperature of the shed. If necessary, it can be sprayed to promote the vegetative growth of plants to reproductive nutrition, inhibit the main shoots, promote flower bud differentiation, and improve the quality of pollen fertilization. More flowering, more fruit, anti-drop fruit, promote development.
2. Nitrogen application is too much. After the sweet pepper enters the fruiting period, the demand for potash fertilizer increases. However, some vegetable farmers are diazotizing potassium when fertilizing sweet peppers, which results in the growth of sweet peppers. In this regard, it is recommended to strengthen the application of potassium fertilizer after the sweet pepper enters the fruiting period. Generally speaking, when the sweet pepper sits on the fruit and the fruit grows to the size of the walnut, it should start to apply potassium fertilizer. It can apply high-potassium water-soluble fertilizer with water to meet the demand of sweet pepper for potassium fertilizer. It can enhance the nutrient matching function of various pepper plants, and the fruit stalks are thickened to prevent deciduous, falling flowers, fruit drop, rapid development, early coloration, thick flesh, bright color, and fragrant to promote the expansion of sweet pepper fruit. (even 3 times)
3. The amount of watering is too large or too small. Sweet pepper belongs to shallow root vegetables, the root system is underdeveloped, and the root system is mainly concentrated in the soil of 10-15 cm deep, which is both afraid of cockroaches and drought. In the result period, if there is water shortage, the plant will be wilting, and the serious fruit will have umbilical rot; if the watering amount is too large, the plant is prone to rooting and dead trees. Therefore, when watering the sweet pepper, do not flood the water, and decide whether to water or not according to the soil moisture and humidity, the weather conditions, and the growth of the sweet pepper.
