摘要
为了保障玉米的高产稳产,以赤峰市敖汉旗玉米田间试验为基础,利用玉米产量数据,研究了氮肥不同施肥时期对玉米产量的影响,以期为提高氮肥的合理利用提供依据。试验结果表明,1/3的氮肥做种肥,2/3的氮肥在玉米大喇叭期做追肥的施用模式效果最好,玉米产量最高,经济效益显著。
In order to ensure high and stable yield of corn, and provide the basis for the reasonable use of nitrogen fertiliz-er, the effect of different nitrogen fertilization period on corn yield was studied based on the corn field experiment in Aohan Banner of Chifeng City. The results showed that the model that one third of the nitrogen fertilizer applied with seeds, and two - thirds of the nitrogen fertilizer top applied during corn big trumpet period was the best. The yield of maize was the highest,and the economic benefits were most significant.
