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.
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.
