| 摘 要： | 针对百色市玉米氮肥施用不够合理,氮肥利用率偏低的问题,进行玉米不同生育期施用不同用量氮肥试验研究,考察施肥比例与产量的关系。试验设苗肥与穗肥施氮量比例分别为A(7:3)、B(6:4)、C(5:5)、D(4:6)、E(3:7)、CK(10:0)共6个处理。结果表明,处理B产量最高,即苗肥与穗肥施氮量比例为6:4产量最高,适宜百色市推广。

| Abstract: | Directing at irrational application of Nitrogen and lower utilization rate in maize at Baisc City, an experiment on different Nitrogen application amounts in different growth periods of maize was conducted to investigate the relationship between fertilizer application proportion and yield. In the ex-periment, the Nitrogen application proportions of seedling fertilizer and earing fertilizer are six treat- ments as A （7：3）, B （6：4）, C （5：5）, D （4：6）, E（3：7） and CK （10：0）. The results show that treatment B has the highest yield, which is suitable to be extended in Baise City. |
