Pepper seed pepper likes temperature, water and fertilizer, but it is easy to get sick at high temperature, die easily after waterlogging, and burn roots after fertilizer. There are different management requirements in different stages of the whole growth period, so it is necessary to promote roots and seedlings before harvesting after planting; From the beginning of harvest to the stage of full fruit, it is necessary to promote seedlings to attack fruits; After entering the high temperature season, it is necessary to protect the roots and seedlings to prevent the death of seedlings; Results In the later period, we should continue to strengthen management and increase production and income.

1. pre-harvest management

During this period, the ground temperature was low and the root system was weak, which should be popularized and controlled. That is, light watering and early topdressing; Diligent cultivation, small squatting seedlings; Slow seedling watering can be combined with chasing a little manure, timely intertillage after watering, raising temperature and maintaining soil moisture, promoting rooting, squatting seedlings should not be too long, about 10 days, and small watering and squatting can be used to adjust the relationship between roots and seedlings. After squatting, water and topdressing in time to improve the early yield. Topdressing is mainly based on nitrogen fertilizer, and some phosphorus and potassium fertilizers are applied to promote seedling health, prevent flower falling, and remove the side branches on the main stem below the first flower in time.

2. Management from the first harvest period to the full fruit period

At this stage, the temperature rises gradually, the rainfall increases gradually, and the pests and diseases occur one after another, which is the key period to determine the yield. In order to prevent premature aging, we should harvest the pepper in advance, water it in time, keep the soil moisture regularly, promote the seedling to attack the fruit, and strive to close the ridge in high temperature season. In the full fruit stage, before closing the ridge, soil should be cultivated to protect the roots, and topdressing should be carried out in combination with soil cultivation.

3. Management in hot season and beyond

It is easy to induce viral diseases in high temperature rainy season, and the flowers and fruits fall off seriously, sometimes a lot of leaves fall off. Therefore, in high temperature and drought years, irrigation must be carried out at the beginning of the drought period, not at the end, so as to keep the soil moist all the time and inhibit the occurrence and development of virus diseases. Apply a small amount of chemical fertilizer to protect seedlings after rain and irrigate them in time to prevent the drought after rainy season from forming the peak of virus disease. Irrigation should be carried out in the morning and evening in high temperature season. Spraying 800 ~ 1000 times chlormequat chloride for 3 ~ 4 times at full flowering stage has a good effect of flower protection and yield increase.

4. Management in the later stage of fruit shrinkage

After the high temperature rainy season, the temperature turned cool and the green pepper plants returned to normal growth. Therefore, it is necessary to strengthen management, promote the formation of the second fruiting peak, increase the late yield, water in time, and combine water and fertilizer with quick-acting fertilizer to supplement the lack of soil nutrition.
