减量施用控释氮肥对玉米产量的影响

摘要

Effects of reduced controlled release nitrogen fertilization on maize yield was studied in this paper. Results showed that single application of controlled release nitrogen fertilizer Ronghedasanyuan of 1 394.1 kg/hm2 can meet nutrition needs of maize whole growth period with good single plant, high yield, and good economic return.%对控释氮肥减量施用且随玉米播种一次性施用研究其对玉米产量的影响。结果表明：在玉米生产中，一次性基施控释氮肥荣和大三元1394.1 kg/hm2，可以满足玉米全生育期对养分的需求，玉米单株性状好，产量高，经济效益佳。
