| 摘 要： | 通过田间试验研究吉林省黑土区不同施氮模式对春玉米产量、养分吸收及利用率的影响。结果表明, 玉米氮肥合理运筹有利于干物质积累和对养分的吸收与利用, 可获得较高的产量、效益和氮肥利用效率。在试验条件下, 施纯N 200 kg/hm2, 1/5氮肥基施、2/5氮肥于拔节期追施、2/5氮肥于大喇叭口期追施的氮肥施用方式, 为黑土区春玉米最佳氮肥运筹模式。

| Abstract: | The effect of different nitrogen application mode to maize yield, nutrition uptake and utilization efficiency was studied through the field experiment in the black soil zone of Jilin province. The result showed that national nitrogen application mode could not only promote the dry matter accumulation, increase the nutrient absorption, but also increase the yield, profit and nitrogen utilization rate for maize. Under this experiment, the optimum nitrogen application mode was N 200 kg/ha, and 1/5 nitrogen fertilizer at first, 2/5 nitrogen fertilizer in jointing stage, 2/5 nitrogen fertilizer in big bell stage, that is the best mode of nitrogen application for spring maize in black soil zone. |
