摘　　要：为探明花生壳为主要原料的有机基质栽培下辣椒最佳氮钾施用量,设置3个施氮量水平(N1,0 kg·hm^(-2);N2,207 kg·hm^(-2);N3,414 kg·hm^(-2))和3个施钾量水平(K1,0 kg·hm^(-2);K2,405 kg·hm^(-2);K3,810 kg·hm^(-2)),共9个配施处理,研究不同氮钾施肥量处理对辣椒生长、品质和产量的影响。结果表明,氮钾配施对辣椒的生长、品质和产量均具有显著影响,在N2K2组合处理下辣椒的生长状况最好;在K2和K3条件下,辣椒的品质综合得分随氮肥增加而降低,在K3水平下辣椒的产量随氮肥的增加而降低。综合考虑品质、产量等因素,在以花生壳为主的基质栽培条件下,施氮量小于120 kg·hm^(-2)、施钾量525~825 kg·hm^(-2)为最佳施肥方案。In order to find out the optimal nitrogen and potassium application amount of pepper under organic substrate cultivation with peanut shell as the main raw material,the effects of different nitrogen and potassium fertilization on the growth,quality and yield of pepper were studied.The plants were subjected to different nitrogen and potassium application(a total of 9 treatments).There are three nitrogen levels(N1,0 kg·hm^(-2);N2,207 kg·hm^(-2);N3,414 kg·hm^(-2))and three potassium levels(K1,0 kg·hm^(-2);K2,405 kg·hm^(-2);K3,810 kg·hm^(-2)).The results showed that the combined application of nitrogen and potassium had significant effects on the growth,quality and yield of pepper.The growth condition of pepper was the best under the combined treatment of N2K2.Under the conditions of K2 and K3,the comprehensive score of pepper quality decreased with the increase of nitrogen fertilizer,and the yield of pepper decreased with the increase of nitrogen fertilizer at K3 level.Considering the factors of quality and yield,the optimal fertilization amount was less than 120 kg·hm^(-2) for nitrogen and 525-825 kg·hm^(-2) for potassium under the substrate cultivation condition of peanut shell.
