To prevent dead trees, it is recommended to cultivate sorghum roots using high sorghum cultivation. The cultivation of sorghum can not only enhance the permeability of the soil, ensure the oxygen needed for root growth, but also help to increase the temperature of the soil, and is particularly suitable for the production of autumn wolfberry and early spring stalk pepper. In addition, sorghum cultivation can also prevent roots from suffocating roots due to excessive watering. When the pepper is planted, the bio-fertilizer resistant to dead trees can be used to promote root disease prevention.

Scientific ventilation, to ensure that the temperature suitable for sharp pepper flowering results of the required temperature of 15 °C ~ 35 °C, if less than 15 °C or higher than 35 °C, sharp pepper buds poorly differentiated, easy to drop flowers and fruit. Before 10 a.m., the greenhouse temperature cannot be higher than 30°C, and pollination of hot peppers is affected above 30°C. Therefore, early ventilation management measures must be taken. After opening the shed for about 1 hour, the ventilation openings can be opened. The size of the ventilation openings and the ventilation time can be determined according to the external temperature conditions. This not only can supplement the carbon dioxide in the shed, but also can control the temperature in favor of peppercorn photosynthetic. The appropriate temperature range of action. In the afternoon, when the shelf temperature reaches 17°C, it is put on the shelf so that the night temperature is maintained at 15°C~18°C, so that the nutrient is normally transported to avoid the nighttime temperature being too high.
