The first is to increase the fruit setting rate of sweet peppers. Don't rely on flowers. Reporters interviewed in the streets around Luocheng City, and learned that because of the small amount of fruit in the head and peppers, some vegetable farmers spent some of their anthers to increase the fruit setting rate of sweet peppers. As a result, the sweet peppers were seated, but there were more malformed Fruits. In addition, the use of anthers to point flowers, black pepper leaves, but also affect the fruit set rate of pods. Sweet peppers are self-pollination crops. As long as the environmental conditions are appropriate, they can sit without any flowers. The vegetable growers reported that the reason why the head pepper sweet peppers are difficult to set up is mainly because the temperature in the greenhouse is too high, which exceeds the suitable growth temperature of sweet peppers, resulting in poor flower bud differentiation and sweet pepper picking. In this regard, it is recommended that vegetable farmers promote fruit setting by adjusting the temperature. The suitable temperature for the pepper flowering period is 25-28°C, and the temperature difference between day and night is 10-12°C. If the night temperature is too high and the temperature difference between day and night is too small, then it is not easy to sit and live. This requires ventilation, sunshade and other measures to control the greenhouse temperature is too high, if necessary, can be sprayed with the help of mastermind or Chrysomolens control plant prosperous, promote flowering and fruit setting.
The second is the excessive use of nitrogen fertilizers and the use of potassium fertilizers. After the sweet pepper enters the result period, the demand for potash has increased. In an interview, the reporter learned that some vegetable farmers pay attention to the use of nitrogen fertilizer when fertilizing sweet peppers, and neglect the use of potash fertilizer, resulting in not only a prolonged growth of sweet pepper, but also a small fruit, poor light, and low yield. In this regard, it is recommended that vegetable growers should strengthen the use of potash after the sweet pepper enters the result period. In general, when the bell pepper is set, the fruit should be topdressed with potash fertilizer when it grows to the size of the walnut. The potash fertilizer can be used with the water to apply high-potassium water-soluble fertilizer to meet the demand of sweet pepper for potash fertilizer and promote the expansion of sweet pepper.
Third, the amount of water should not be too large or too small. Sweet peppers are shallow-rooted Vegetables with undeveloped root systems. The roots are concentrated in soils 10 to 15 centimeters deep, both for fear of drought and drought. In the result period, if there is water shortage, the plants appear wilting, and the severe fruits have umbilical rot. If the watering quantity is too large, the roots and dead trees will appear easily. Therefore, it is recommended that vegetable farmers do not flood the water when watering sweet peppers. Watering or not should be determined according to the degree of soil moisture, weather conditions, and the growth of sweet peppers.
