不同施肥方式对夏玉米产量的影响

The Effect of Different Fertilization Methods on the Yield of Summer Maize

为探索适合本地夏玉米的合理施肥方式,选择当地常见的3个玉米品种和3个种植密度,对比一次施肥和分次施肥2种施肥处理下玉米的产量差异。结果显示,在同播期同密度条件下,先玉335、登海618和登海605均表现为分次施肥产量大于一次施肥的产量。

In order to explore a reasonable fertilization method suitable for local summer maize, three local common maize varieties and three planting densities are selected, and the yield differences of maize under one-time fertilization and fractional fertilization are compared. The results shows that Xianyu 335, Denghai 618 and Denghai 605 yield of fractional fertilization is greater than that of single fertilization under the same sowing date and density.
