Effects of substitution and reduction of water soluble fertilizer on the yield,quality and soil nutrient residue of pod pepper
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.
