摘　　要：研究吉林中部大豆高产氮、磷、钾肥适宜用量，为大豆高产高效施肥提供依据。2006～2007年，以吉育88为供试品种，设计了氮、磷、钾肥量级田间试验。结果表明：吉林中部大豆高产氮肥适宜刚量为4567．5kg·m^-2，磷肥（P2O5）适宜用量为60-90kg·hm^-2钾肥（K20）适宜用量为45～80k·hm^-2氮、磷、钾肥对大豆产量的影响顺序为N〉P〉K，The optimum rate of NPK fertilizer application for soybean was studied at central area of Jilin Province, in order to provide the basis for high yield and high efficient of soybean production. By making Jiyu 88 as experimental cuhivar, designed the different fertilizer level on NPK in field during 2006-2007. The resuhs showed the optimum rates of N, P, K application were 45- 67.5 kg·ha^-1 ,60- 90 kg·ha^-1, 45- 80 kg·ha^-1 respectively. The effect order of NPK fertilizer on soybean yield was N 〉 P 〉 K.
