摘　　要：为探究适于朝天椒生产的水溶肥最佳施用方式,通过田间试验研究水溶肥替代常规化肥及减量对朝天椒产量、品质及土壤养分残留的影响,共设置7个处理:CK(常规化肥)、T1(100%替代)、T2(T1减量20%,100%替代)、T3(T1减量40%,100%替代)、T4(50%替代)、T5(T4减量20%,50%替代)、T6(T4减量40%,50%替代)。结果表明,与CK相比,T1和T4处理产量分别提高21.09%和26.92%,品质提高;减量20%条件下,T2和T5处理产量分别提高14.28%和15.23%,品质提高;减量40%条件下,T3和T6处理产量分别提高7.41%和4.29%,品质提高,土壤养分残留量降低。综合考虑朝天椒的产量、品质及环境效益,水溶肥50%替代优于100%替代,替代后减量20%~40%在生产上是可行的。T5处理是生产上适宜推广的最佳施用方式。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.
