By utilizing the strong regenerative capacity of peppers, the pruning after the end of the harvest of the summer peppers can be used again to save the seedling time and increase the yield and efficiency. First, timely and appropriate pruning After the end of the prime period, it is necessary to cut off the branches and weak branches and diseased branches above three inches, but be careful not to overdo it, so as not to reduce the fruit setting rate. The pruning time should be chosen from 8 to 9 am on a sunny day to ensure that the wound heals on the day and avoid infection. Second, strengthen management Within half a month after pruning, it is a key period for the growth and development of new branches, new leaves and flower buds. The management of fertilizer and water should be done well. Generally, the manure per manure is 3000-4000 kg, the cake fertilizer is 25-30 kg, and the compound fertilizer is 12 ~ 13 kg or 10 kg of urea. After fertilization, in case of dry weather, water should be watered in time and roots should be cultivated. After planting, plant phytohormone should be sprayed once a week to promote the rapid growth of new shoots. After trimming, due to sufficient fertilizer, the new shoots are born a lot, and it is necessary to re-pruning at the right time. When the new shoots grow to about 15 cm, they begin to bud, leaving 4 to 5 new shoots per plant, and the rest are cut off. Third, timely film insulation Recycled peppers entered the fruiting period in October. As the temperature dropped, in addition to timely harvesting, the plastic shed should be covered before the frost. From the beginning of November, a small arch shed will be added to the cold shed for cold insulation. From the middle of November, the straw curtain is insulated at night, and the conditional leaf surface can be sprayed with antifreeze. Fourth, timely pest control The insect pests of pepper include cotton bollworm, tobacco budworm, aphid, etc., and can be sprayed with 10% imidacloprid and 4.5% beta-cypermethrin. After pruning, due to more wounds, it is easy to be infected with viral diseases. It can be sprayed with virus A500 times liquid or phytopathogenic plus photosynthetic fertilizer, and sprayed once every 7 days.
