How to realize Pepper Regeneration after Autumn in greenhouse

First, pruning timely and appropriately. When pruning, it is appropriate to cut off more than three branches and leaves and weak, diseased branches and leaves, but should not be excessive, so as not to reduce the fruit setting rate. The pruning time should be from 8 am to 9 am on a sunny day to ensure that the wound can heal on the same day and reduce the invasion of germs.

Second, strengthen the cultivation and management. Within half a month after pruning, it is a critical period for the growth and development of new branches, new leaves and flower buds, so water and fertilizer management should be done in time. Generally, 3000 to 4000 kilograms of human feces and urine, 25 to 30 kilograms of cake fertilizer and 12 to 13 kilograms of compound fertilizer (or 10 kilograms of urea) are applied per mu. If drought occurs after application, it should be watered in time, and the soil should be cultivated to protect the root. Plant probiotics was sprayed once a week after pruning to promote the rapid growth of new branches. After pruning, due to sufficient fertilizer, there are a lot of new branches, which should be pruned at the right time.

Third, timely coating and heat preservation. The regenerated pepper began to set fruit around the middle of September and entered the full fruiting period in October. The temperature dropped gradually after "Cold Dew". In addition to timely harvest and listing, plastic sheds should be covered before frosting to increase the temperature. From the first ten days of November, small arch sheds should be set up in the greenhouse to protect against cold and heat preservation. If red peppers are harvested before the Spring Festival, grass curtains should be covered at night from mid-November to keep warm, and conditional leaves should be sprayed with antifreeze.

Fourth, timely pest prevention and treatment. The main pests of regenerated pepper are cotton bollworm, tobacco green worm, aphid and so on, which can be sprayed with 700 times liquid of aphid Qingling. After pruning, because there are many wounds, it is easy to infect virus disease, so it can be sprayed with virus A500 times liquid or phytoling plus photosynthetic micro-fertilizer every 7 days.
