The Latest Technical Guide to Sweet Pepper Cultivation and Management
Sweet pepper is actually a variety of chili pepper, but compared with chili peppers, sweet pepper basically has no spicy taste and instead carries a slight sweetness, which is why it is loved by many people. At present, the cultivation area of sweet pepper in our country is still very large, and when we grow sweet pepper, its management work is very important. So how should sweet pepper be managed during cultivation? Today, the editor brings you the cultivation and management techniques for sweet pepper. Let's take a look together below!
1. Do not blindly apply flower-setting agents
When growing sweet pepper, if it encounters continuous cloudy weather, then the fruit-setting ability of sweet pepper is very poor. Therefore, many people become very anxious when they see that sweet pepper is not setting fruit, and so they carelessly use flower-setting agents to treat the flowers. Although the sweet pepper plants may indeed set fruit, the fruit produced is small and hard. Moreover, the growth rate is also very slow, and some may even become stiff fruit. Therefore, growers can only remove these deformed fruits. Sweet pepper is actually a self-pollinating vegetable, and as long as a suitable environment is ensured, it can set fruit normally.
During the flowering and fruiting period of sweet pepper, the temperature should be controlled at about 25 degrees, with the day-night temperature difference maintained at 10 degrees. The nighttime temperature should not be too high; if the nighttime temperature is too high, then the fruit-setting rate will decrease as a result. Therefore, attention should be paid to doing good shading work, providing appropriate ventilation, and avoiding excessively high temperatures. If necessary, an appropriate amount of growth retardant can be sprayed to prevent excessive vegetative growth in sweet pepper and increase the number of flowers and fruits on the sweet pepper plants. In addition, on cloudy days, the method of shaking the plants can be used to promote fruit setting, but flower-setting agents must not be applied, otherwise the plants are prone to hormone poisoning, and the fruit quality will also decline as a result.
2. Watering management
The root distribution of sweet pepper is relatively shallow, and the root system is not very developed. Usually most of the roots are concentrated in the soil at about 12 cm, and its tolerance to drought and waterlogging is relatively poor. Therefore, attention must be paid to controlling the amount of watering well, not only to meet the water needs of sweet pepper, but also to prevent root rotting caused by too much water. However, during the fruiting period of sweet pepper, water must not be lacking, as it will not only affect fruit setting but also make it prone to diseases such as blossom-end rot. However, flood irrigation should also not be used, otherwise it can easily cause sweet pepper to wilt and even lead to plant death. Therefore, when watering, the amount of water should be controlled according to the degree of soil moisture, and flood irrigation should not be used.
3. Application of potassium fertilizer
During the growth period, sweet pepper has a very large demand for fertilizer. Among the basic elements such as nitrogen, phosphorus, and potassium, potassium is needed the most, followed by nitrogen, and finally phosphorus. Throughout the entire growth period, if sweet pepper lacks potassium fertilizer, then sweet pepper is very prone to lodging. The fruit will also become very small, and the yield will decrease. Therefore, after sweet pepper sets fruit, when the fruit grows to about the size of a ping-pong ball, an appropriate amount of high-potassium fertilizer should be applied in time to meet the potassium fertilizer needs of sweet pepper growth, control the amount well, ensure the yield of sweet pepper, and promote normal growth.
The above is a brief introduction to the cultivation and management techniques for sweet pepper. That is all for today's introduction. This article is for reference only, and we hope it can help everyone!
