Greenhouse bell pepper planting, how to avoid empty seedlings and no peppers
In the process of greenhouse bell pepper planting, the problem of empty seedlings and no pepper is relatively common, which has brought a lot of trouble to growers. To solve this problem, we need to start from a number of aspects, including variety selection, temperature management, water and fertilizer application, and pest and disease control. This article will elaborate on these aspects to help growers better manage the bell peppers in greenhouses and avoid the occurrence of empty seedlings and no peppers.
First, the selection of varieties.
Choosing a variety of bell pepper suitable for greenhouse cultivation is the key to avoiding empty seedlings and not bearing peppers. When selecting varieties, it is necessary to pay attention to selecting varieties with strong disease resistance, wide adaptability and high yield. In addition, it is necessary to choose the appropriate type of ripening according to the local climatic conditions and market demand. For early spring stubble cultivation, early-maturing varieties should be selected; For autumn and winter stubble cultivation, medium and late maturing varieties should be selected.
2. Temperature management.
The suitable temperature for the growth of bell pepper is 20-30, and when the temperature is too high or too low, it is easy to cause problems such as falling flowers and fruits and empty seedlings. Therefore, in the process of planting bell peppers in greenhouses, it is necessary to pay attention to adjusting the temperature in the greenhouse and maintaining a suitable growth temperature. In winter and spring, pay attention to heat preservation; In summer and autumn, pay attention to cooling. At the same time, it is also necessary to avoid high and low temperatures to reduce the impact on the growth of bell peppers.
3. Water and fertilizer application.
Reasonable water and fertilizer management is an important measure to avoid empty seedlings and no peppers. In terms of watering, it is necessary to water the bell pepper in a timely and appropriate amount according to the different stages of growth and soil conditions to keep the soil moist. In terms of fertilization, it is necessary to pay attention to balanced fertilization, increase the application of organic fertilizer and phosphorus and potassium fertilizer, and control the amount of nitrogen fertilizer. At the same time, according to the growth of bell peppers, trace elements should be supplemented in time to meet the needs of their normal growth.
Fourth, pest control.
Pests and diseases are one of the important reasons for the empty seedlings of bell peppers. Therefore, it is very important to do a good job of pest control. It is necessary to regularly check the growth of bell peppers, and find and improve pests and diseases in time. At the same time, it is necessary to pay attention to prevention and adopt various measures such as agricultural, biological, and chemical prevention and control to comprehensively prevent and control the occurrence and spread of pests and diseases. When using chemical agents, it is necessary to strictly follow the instructions for use and avoid overuse and abuse.
Fifth, reasonable dense planting.
Reasonable dense planting can improve the light and ventilation conditions of bell peppers, improve the efficiency of photosynthesis, and reduce the occurrence and spread of diseases. When planting, it is necessary to determine the appropriate planting density according to factors such as variety characteristics and soil fertility. Generally speaking, the planting density of early-maturing varieties can be appropriately dense, and that of medium-late maturing varieties should be thinner. At the same time, it is also necessary to pay attention to reasonable pruning and pruning to keep the plants well ventilated and transmitted.
6. Harvest at the right time.
Timely harvesting is also one of the important measures to avoid empty seedlings and no peppers. At the time of harvesting, it is necessary to determine the appropriate harvest period according to market demand and variety characteristics. Generally speaking, bell peppers are harvested when the fruit is full and brightly colored. After harvesting, it should be processed and sold in a timely manner to avoid affecting quality and yield due to overripeness or decay.
In short, in order to avoid the problem of empty seedlings and no pepper in the process of greenhouse bell pepper planting, it is necessary to start from many aspects, including variety selection, temperature management, water and fertilizer application, pest control, reasonable dense planting and timely harvesting. Only by comprehensively applying these measures can we improve the yield and quality of bell peppers and bring better economic and social benefits to growers.
