Drying seeds 1 ~ 2 days before sowing plays a great role in improving seed vigor, germination rate and germination speed, and accelerating germination and emergence. At the same time, it also has a certain sterilization and disinfection effect. Pepper seeds can carry pathogens of anthrax, plague, chilling injury, imported diseases, scab and other diseases. Disinfecting seeds before sowing is one of the simple methods to prevent diseases. It can be scalded with hot water to kill germs attached to the surface of seeds and lurking inside seeds. Soaking seeds with water first can reduce the influence of ironing on seed germination, and can also germinate the germs of seeds, making them easy to be heated. Remove the water of swollen seeds, and then heat them in hot water at 52~ 55℃ for 15 minutes.

In order to ensure the sterilization effect, the water temperature should be ensured. When the water temperature drops, insert a thermometer to heat the water. Reach the specified perm time. Immediately after scalding, take the seeds out of hot water and put them in cold water for cooling to prevent the residual heat from damaging the seeds. It is best to soak the seeds in ordinary warm water for 4-5 hours in advance, and then soak them in copper sulfate 1%, potassium permanganate solution 0. 1% for 5 minutes or formalin solution 100 times for about 20 minutes after adding water. In order to prevent pepper virus disease, the seeds soaked in advance can be soaked in 10% trisodium phosphate solution for 20 minutes. After soaking with drugs, the seeds should be washed with clear water before germination or direct seeding. Otherwise, it will affect seed germination.

Pruning pepper plants is an effective measure to increase yield. The experiment showed that reasonable pruning of pepper could increase the yield by 15% ~ 20%. Pruning time is usually from late July to mid-August. At this time, the first batch of pepper fruits have been harvested, and the plants are in the dormancy period of eggplant with little temperature difference between day and night, which has the best effect of increasing production. After the pruning part enters the high temperature period, the four branches of the plant will extend to eight lateral branches, and then the branches will flourish, which will affect the penetration of the wind, not only the fruit is small, but also the fruit is easy to rot and cause various diseases. Even if the output drops, the quality will deteriorate. Cutting off these eight side branches in time can concentrate the fertility on the four big branches, making the pepper grow longer and bear more fruits.

The pruning method should be trimmed with sharp pruning shears, and the cut should be smooth, so as not to cause pests or induce diseases with scissors. When cutting eggplant, cut off eggplant with serious pests and diseases, resulting in too many drooping eggplant in the early stage and improper management of broken branches. Cut branches should be collected for yard treatment, especially pests and diseases should not be left in the yard. Post-harvest management should yield 5 ~ 7.5 kg per mu to promote growth and fruiting. If it is dry, water it with autumn rain on time. In addition, foliar fertilizer is used once every 7 days, 2 ~ 3 times, 250g sugar-free, 150g potassium dihydrogen phosphate, diluted and sprayed evenly. Spraying is best done on cloudy or sunny nights.
