摘　　要：在砂浆黑土区和潮土区对玉米分别进行田间试验,目的在于筛选出适合当地的复合肥配方,减少肥料用量,增加经济效益。2种不同土壤试验结果表明:4个处理中,以缓释肥(25-10-10)处理产量最高,分别为7 954 kg/hm2和8 365 kg/hm2,其利润也最高,分别为13 373元/hm2和14 154元/hm2;缓释肥(25-10-10)处理比CK(不施肥)处理分别增产3 498 kg/hm2和3 491 kg/hm2,利润分别增加4 907元/hm2和4 893元/hm2,均优于其他2个施肥处理,而且在氮肥施用量上比其他施肥处理降低10.7%。Field experiments on corn are conducted in mortar black soil region and moist soil region, and the purpose is to screen out appropriate compound fertilizer formulations for local use, decrease in fertilizer use, and improve economic benefit. Experiments in two different soils show that in four treatments those with the slow-release fertilizer （25-10-10） give the highest yields, being 7 954 kg/hm2 and 8 365 kg/hm2, respectively, and also the highest profit, 13 373 yuan/hm2 and 14 154 yuan/hm2, respectively; treatment with the slow-release fertilizer （25-10-10） is higher in yield than treatment with no fertilizer application CK by 3 498 kg/hm2 and 3 491 kg/hm2, respectively ; with additional profit of 4 907 yuan/hm2 and 4 893 yuan/hm2 , respectively, the results are superior to those of the other two applications, and the quantity of nitrogenous fertilizer applied is lower than other fertilizers by 10.7%
