| 摘 要： | 在黄淮海地区小麦-玉米一年两熟种植模式下，常规施氮270 kg/hm2且氮磷肥配施比为3∶1时，夏玉米叶片衰老较缓慢，花后光合能力较强，穗粒数增加，获得夏玉米高产；减量施氮33%并调整氮磷比为2∶1，可延缓夏玉米花后叶片衰老，提升花后光合能力，获得夏玉米丰产高效。综上，施用磷肥90 kg/hm2且维持氮磷配比为2∶1至3∶1，利于夏玉米高产高效。

| Abstract: | Under the wheat-maize two-cropping mode of wheat-maize in the Huang-Huai-Hai region, when the conventional nitrogen application was 270 kg/ha and the ratio of nitrogen and phosphorus fertilizer was 3:1, the leaf aging of summer maize was slower, the photosynthetic ability after anthesis was stronger, the number of panicle grains increased, and the high yield of summer maize was obtained. Reducing the amount of nitrogen by 33% and adjusting the nitrogen-phosphorus ratio to 2:1 can delay the leaf aging of summer maize after anthesis, improve the photosynthetic ability after anthesis, and obtain high yield and high efficiency of summer maize. In summary, the application of 90 kg/ha of phosphate fertilizer and the maintenance ratio of nitrogen and phosphorus from 2:1 to 3:1 can be conducive to the high yield and high efficiency of summer maize. |
