摘要
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。
The effect of balanced fertilization on increasing yield and benefit of hot pepper was studied. The results of a field experiment in red paddy soil with middle fertility in Luodian county of Guizhou province showed as follow. The ratio of output and input of P and K fertilizers is 28.2～31.2∶11.73～11.89, respectively and the optimum ratio of N∶P 2O 5∶K 2O is 1∶1.06～1.43∶1.06～1.27, and the suitable application amount of K 2O and P 2O 5 are 75～112 kg/ha,when the applied amount of N is within 94～110 kg/ha .
