Abstract: Experimental studies were carried out on the effects of new fertilizers, including reducing fertilizer application, increasing organic fertilizer on the yield, quality and soil of pepper. The results showed that the treatment of 7 500 kg of organic fertilizer per hectare and 30% less fertilizer than normal fertilizer was more effective than that of a single chemical fertilizer, and the yield related traits such as weight increased, nitrite content was significantly reduced, vitamin C and soluble protein content was increased. Under the synergistic effect of fertilizer and organic fertilizer, the fruit characters of the compound fertilizer 1 260 kg plus microorganism organic fertilizer 7 500 kg were the best, the yield was the highest and the quality was better. Compared with single fertilizer, the yield of water-soluble fertilizer was the highest. The treatment of trace elements in application had the lowest fruit rate of malformation. Controlled release fertilizer could improve fruit quality and reduce nitrite content. In view of the problems of soil acidification and unscientific nutrient ratio after the experiment, it was suggested to apply formula fertilization scientifically.
