摘　　要：采用随机区组的方法,研究固原地区微量元素肥对玉米产量的影响,结果表明:施用硫酸锌和硫酸锰玉米增产1204.16~1981.25 kg/hm^2。施用硫酸锌30 kg/hm^2,在玉米6~8叶期喷施0.10%的硫酸锌溶液750 kg/hm^2,玉米大喇叭口期叶面喷施0.15%的硫酸锌750 kg/hm^2时产量最高,达13710.42 kg/hm^2,比对照增产1981.25 kg/hm^2;纯收入11670.84元/hm^2,比对照高2387.50元/hm^2,施用微量元素肥料玉米增产明显。The application effect of trace element fertilizer on maize was explored by the method of random block experiment.The results showed that the application of different trace elements zinc sulfate and manganese sulfate had certain influence on maize yield,and the yield increased by 1204.16~1981.25 kg/hm^2.The highest yield(13710.42 kg/hm^2)was obtained when 30 kg/hm^2 zinc sulfate was applied to maize at the growth stage of 6~8 leaves with 0.10%zinc sulfate solution(750 kg/hm^2),and 0.15%zinc sulfate solution was sprayed(750 kg/hm^2)on the leaves at the bell-mouth stage.The highest yield was 1981.25 kg/hm^2 higher than that of the control.Net return was 11670.84 yuan/hm^2,which was 2387.50 yuan/hm^2 higher than that of the CK.Applying trace element fertilizer on maize can significantly increase the yield.
