摘　　要：在地膜覆盖和灌水条件下,以郑单958为供试品种,进行氮、磷、钾肥量级田间试验,研究吉林西部半干旱区玉米高产氮、磷、钾肥适宜用量。结果表明,吉林西部半干旱区玉米高产氮、磷、钾肥施用量分别为190~210 kg/hm2、75~150 kg/hm2、180~240 kg/hm2。在该土壤条件下,玉米高产氮肥适宜用量为N 190.0 kg/hm2、磷肥（P2O5）适宜用量为124.4 kg/hm2、钾肥（K2O）适宜用量为178.5 kg/hm2。The optimum rate of NPK fertilizer application for corn was studied to provide the basis for high yield of corn and high fertilization efficient at western semiarid area of Jilin province.Zhengdan 958 was used as experimental cultivar,and the field experiments of different fertilizer level on NPK were designed under plastic film mulching and irrigation.By the data analysis,the application rate of N,P2O5 and K2O fertilizer were 190~210 kg/hm2,75~150 kg/hm2,180~240 kg/hm2 respectively at western semiarid area..The results showed the optimum rates of N,P,K application were 190.0 kg/hm2,124.4 kg/hm2,178.5 kg/hm2 respectively under this type of soil.
