The results showed that, under the same field management, the two fertilization methods had no effect on the time when maize plants grew into each growth stage; the one-off fertilization was slightly better than the traditional fertilization in dry weight of each part of the plant, ear traits and yield; and the values of the two methods of fertilization varied from each other and were unstable. In production, the one-off fertilization saves the top dressing process, simplifes the operation process and reduces the production input, which is of great signifcance to the development of modern agriculture.展开更多
