How to manage bell peppers during the fruit-setting stage? Master the latest key technical points
Bell peppers are now very common in China, and their planting area is also very large. When growing bell peppers, their management work is very important. When managing bell peppers, we need to appropriately adjust our management measures according to the growth stage of the bell peppers. Especially during the fruit-setting stage of bell peppers, if management is poor, the impact on their yield is very great. So how should bell peppers be managed during the fruit-setting stage? Below, the editor will briefly introduce it for everyone. Let's take a look together!
1. Proper ventilation
When growing bell peppers, proper ventilation and maintaining suitable temperature and humidity are the key to ensuring the fruit-setting rate of bell peppers. After the bell pepper seedlings have recovered from transplanting, under the premise of ensuring temperature, ventilate as much as possible to avoid excessively high humidity in the greenhouse. In the early stage, the temperature should be maintained at around 30 degrees, and then as time goes on, appropriately lower the greenhouse temperature. By the time the bell peppers reach the flowering and fruiting stage, the temperature should gradually be lowered to around 22 degrees. A suitable temperature and humidity environment can ensure that the bell pepper plants are short and sturdy with short internodes, and the fruit-setting rate can also be improved as a result.
2. Water and fertilizer management
The leaves of bell peppers are relatively small, so their water evaporation is not very large. Therefore, when watering after the bell pepper seedlings are planted, pay attention to controlling the amount of water. Then, from after the seedlings recover from transplanting until harvest, try not to water. Otherwise, it is easy to cause flower drop and fruit drop in bell peppers. Then, after the first crop of bell pepper fruits is harvested, strengthen water and fertilizer management, appropriately increase organic fertilizer, and increase the application amount of phosphorus and potassium fertilizer. Then an appropriate amount of Zhuangdiling can be sprayed on the leaves to reduce flower drop and fruit drop in the plants, promote fruit expansion, and improve the yield and quality of bell peppers.
3. Improve lighting
Light is also very important for the growth of bell peppers. During the fruit-setting stage of bell peppers, we should pay attention to improving light for bell peppers. Appropriately increase the temperature. If encountering cloudy and snowy weather, then supplemental lighting can be appropriately added in the greenhouse, and a reflective film can also be hung on the back wall to increase the area of light in the greenhouse. Then also pay attention to regularly cleaning the greenhouse film to improve the light transmittance of the film, strengthen management, and do a good job in pruning and removing branches. Remove excess branches and leaves from the plants, especially the branches and leaves in the inner canopy, so as to improve the light exposure rate of leaves and flowers, avoid excessive nutrient consumption, and improve the fruit-setting rate.
4. Reduce humidity
During the flowering stage of bell peppers, if successful pollination is desired, the humidity requirements are very high. Therefore, if encountering continuous low-temperature cloudy weather, the humidity in the greenhouse can easily become too high, causing bell pepper pollen development to be hindered, with insufficient activity, making normal pollination impossible. So in this kind of weather, according to weather changes, ventilate appropriately to lower the temperature and reduce humidity, and lower the humidity in the greenhouse. Then an appropriate number of bees can be released in the greenhouse, which can effectively improve the fruit-setting rate of bell peppers.
The above is a brief introduction to how to manage bell peppers during the fruit-setting stage. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
