(A large number of results, nitrogen: phosphorus: potassium = 18:5:22 and calcium, magnesium, zinc, iron and other trace element fertilizers, acre (usage area) once topdressing 30 to 50 kg. Pepper harvesting should not be empty , in case the upper part is not fruitful.

6. The fungicide should be sprayed in time before and after the pepper is harvested to prevent the rot of the stem from invading the wound.
