Three key points should be emphasized for high yield and high quality of sharp pepper

Gong Zhichang, known as the "king of sharp peppers" in Shouguang City, Shandong Province, believes that yield and quality are the key to the efficiency of sharp peppers, especially when the market price is low. Gong Changzhong has grasped the following three aspects of management in the production of sharp pepper.

To prevent dead plants and cultivate developed root sharp pepper is a shallow root plant, its main root is undeveloped, its root regeneration ability is poor, and it is afraid of waterlogging and drought tolerance, which requires strong soil permeability, so high border cultivation should be adopted. High border cultivation can not only enhance the air permeability of soil and ensure the oxygen needed for root growth, but also improve the soil temperature, which is especially suitable for the production of sharp pepper in autumn and winter and early spring. In addition, high border cultivation can also prevent root suffocation and retting caused by excessive watering. The application of biological fertilizer of anti-dead plants in the planting of sharp pepper can promote root disease prevention.

Scientific ventilation to ensure that the temperature is suitable for the flowering and fruiting period of sharp pepper requires a temperature of 15 ℃ ~ 35 ℃. If it is lower than 15 ℃ or higher than 35 ℃, the flower bud differentiation of sharp pepper is poor, and it is easy to drop flowers and fruits. Before 10:00, the temperature in the greenhouse should not be higher than 30 ℃, and the temperature higher than 30 ℃ would affect the pollination of sharp pepper, so early ventilation should be taken. When the shed is opened for about 1 hour, the vent can be opened, and the size of the vent and the ventilation time can be determined according to the external temperature, which can not only supplement the carbon dioxide in the shed, but also control the temperature in the suitable temperature range for the photosynthesis of sharp pepper. In the afternoon, when the greenhouse temperature reached 17 ℃, the night temperature was kept at 15 ℃ ~ 18 ℃, so that the nutrition could be transported normally, so as to avoid excessive night temperature and excessive consumption of nutrients, resulting in plant growth and poor flowering and fruiting.

Reasonable pruning and coordinated plant growth and pruning can improve the ventilation and light transmittance of the plant population, which is not only conducive to the manufacture and transport of photosynthates, but also conducive to the improvement of pepper yield and commerciality, but also conducive to the prevention of diseases and insect pests. In a large stubble, the pruning of the four main branches is the main way of pruning, and the germinating lateral branches are removed to ensure the coordinated upward growth of the four main branches. In general, the fruit begins to be pruned after sitting, so the plant is shorter, the field ventilation and light transmittance is good, and lateral branches can be left to bear fruit. When the lateral branch sits on the fruit, leave a leaf in the upper part of the fruit to pick the heart. When the fruit is picked, the fruit and fruit-bearing lateral branches can be removed together. With the growth of the plant, branches and leaves crisscross, affecting ventilation and light transmission, combined with fruit picking, it is necessary to remove the inner side branches in time to prevent them from consuming nutrients. The outer lateral branches are still carried out in accordance with the management method of keeping fruit and picking the heart.
