Detailed Explanation of Key Technical Points for Growing Green Peppers in Greenhouses
First, sterilize and germinate the selected seeds, then sow them in a seedbed to raise seedlings. After the seedlings emerge, transplant them at the right time, with a planting density of 3000-4000 holes/mu. After transplanting is completed, water and fertilize according to the growth habits of the peppers, and at the same time carry out pest and disease control management work.
The following points should be noted when growing green peppers in greenhouses:
1. Strong green pepper seedlings should be cultivated in the early stage
Strong seedlings of green peppers are the foundation of high yield. In seedbed management, damping-off of green peppers should be controlled in time. After the green peppers emerge, the amount of watering should not be too much or too little. The seedbed should also focus on controlling tobacco whitefly and leaf spot disease on green peppers.
2. Base fertilizer for green peppers must be applied well
The base fertilizer for green peppers is also very important; it can even determine the entire life of the green peppers. The use of base fertilizer for green peppers should adhere to giving priority to increasing the application of organic fertilizer, advocate adding microbial bacterial fertilizer, rationally use commercial chemical fertilizers, and appropriately supplement trace fertilizers
3. Plot selection must be appropriate
Field plot selection should be carried out according to the biological characteristics of green peppers. Soil that is loose and has relatively high organic matter content is most suitable for planting green peppers. If the previous crop used a herbicide to which green peppers are relatively resistant, then it should not be used to plant green peppers.
4. Preventive management during the high-temperature season must be done well
The high-temperature rainy season easily induces viral diseases, causing severe flower and fruit drop, and sometimes a large amount of leaf drop. Therefore, in high-temperature and dry years, irrigation must be done at the beginning of the dry period, not at the end of the dry period, always keeping the soil moist to inhibit the occurrence and development of viral diseases. After rain, apply a small amount of chemical fertilizer to protect the plants, and also irrigate in time to prevent drought after the rainy season from forming a peak of viral diseases. In the high-temperature season, irrigation should be done in the morning and evening. During the full flowering stage, spray 800-1000 times chlormequat 3-4 times, which has a good effect on preserving flowers and increasing yield.
Growing green peppers in greenhouses allows for early maturity and high yield, and the cultivation benefits are also better than open-field cultivation. Therefore, growers who have the conditions and ideas can learn more about it.
