摘　　要：为指导阿克苏市玉米科学合理施肥,提高肥料利用率,实现化肥减量目标,以金谷玉6号为试验材料,研究测土配方施肥对玉米产量及养分利用率的影响。结果表明:测土配方施肥处理(施尿素446.7 kg/hm^(2)、重过磷酸钙375 kg/hm^(2)、硫酸钾156 kg/hm^(2))对玉米生长、产量及经济效益均有促进作用,净收入可达19 140.45元/hm^(2);养分利用率分别为氮肥36.26%,磷肥17.39%,钾肥41.99%。In order to guide the scientific and rational fertilization of maize in Aksu City,improve fertilizer use efficiency,and achieve the goal of fertilizer reduction,the effects of soil testing formula fertilization on yield and nutrient use efficiency of maize were studied using Jinguyu 6 as the experimental material.The results showed that the soil testing and formula fertilization treatment(application of urea 446.7 kg/hm^(2),heavy superphosphate 375 kg/hm^(2),potassium sulfate 156 kg/hm^(2))had a promoting effect on maize growth,yield,and economic benefits,with a net income of 19140.45 yuan/hm^(2);nutrient use efficiency was 36.26% for nitrogen fertilizer,17.39% for phosphorus fertilizer,and 41.99% for potassium fertilizer,respectively.
