为探索平衡施肥的增产增收效应,探索辣椒氮、磷、钾适宜比例和用量,筛选氮、磷、钾最佳配方,为茄果类蔬菜的高产栽培提供科学依据,进行了辣椒平衡施肥试验。田间试验表明:在罗甸县肥力中等的红泥田上栽种早菜辣椒,钾肥的产投比为28.2～31.2,磷肥的产投比为11.73～11.89,最优N∶P2O5∶K2O为1∶1.06～1.43∶1.06～1.27,当施N94～100kg/hm2时,P2O5和K2O的最佳施用量为75～112kg/hm2。 In order to explore the effect of balanced fertilization on yield and income, explore the optimum proportion and dosage of nitrogen, phosphorus and potassium in pepper, and select the best formula of nitrogen, phosphorus and potassium to provide scientific basis for the high yield cultivation of eggplant vegetables. Field experiments showed that the yield and potash ratio of potash was 28.2-31.2, the yield of phosphate fertilizer was 11.73-11.89, the best N: P2O5:K2O was 1: 1.06 ~ 1.43:1.06 ~ 1.27. When applying N94 ~ 100kg / hm2, the best application rate of P2O5 and K2O is 75 ~ 112kg / hm2.
