Pepper likes temperature, water and fertilizer, but high temperature is easy to get sick, waterlogging is easy to kill seedlings and fertilizer is easy to burn roots. 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.

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, irrigation must be started in the drought period in high temperature and drought years, not at the end of the drought period, 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 of chlormequat chloride for 3-4 times at full flowering stage has a good effect of flower protection and yield increase.
