Abstract：In order to explore the best application mode of water-soluble fertilizer suitable for the production of pod pepper,field experiments were conducted to study the effects of replacement and reduction of water-soluble fertilizer on the yield,quality and soil nutrient residues of pod pepper,and a total of 7 treatments were set,CK(conventional chemical fertilizer),T1(100％ substitution),T2(T1 mass loss 20％,100％ substitution),T3(T1 mass loss 40％,100％ substitu-tion),T4(50％ substitution),T5(T4 mass loss 20％,50％ substitution),T6(T4 mass loss 40％,50％ substitution). The results showed that compared with CK,the yield of T1 and T4 treatments increased by 21.09％ and 26.92％,respectively,and improved the quality. Under the condition of 20％ nutrient reduction,the yield of T2 and T5 treatments increased by 14.28％ and 15.23％,respectively,and improved the quality. Under the condition of 40％ nutrient reduction,the yield of T3 and T6 treatments increased by 7.41％ and 4.29％,respectively,and improved the quality,and the soil nutrient residue was reduced. Considering the yield,quality and environmental benefits of pod pepper,50％substitution of water-soluble fertilizer is better than 100％ substitution,and the reduction of 20％-40％ after substitution is feasible in production. T5 treatment is the best application mode of water-soluble fertilizer for promotion in production.
