摘要：

为了提高氮肥利用率，减轻劳动强度，达到农业增产和农民增收的目的。在等氮量条件下，以山东省桓台县为例，通过基肥机械侧条施肥和常规混施对比田间试验，研究不同施肥方式对夏玉米性状及产量的影响，并验证侧条施肥的效应。结果表明，侧条基施与常规混施的夏玉米相比，在生殖生长和营养生长时期植株旺盛、子粒增产，产量分别比常规混施和不施氮处理高3.2%、7.9%，并且得出施肥在一定程度上会起到调节土壤水分含量的作用。

Abstract:

In order to increase the nitrogen use efficiency, reduce labor intensity and improve the agricultural production and farmers' income, the field experiment has been done in Shandong Province under the same quality of nitrogen. The study researched on the effect of the fertilization methods on the growth, development and output of summer corn through the mechanical side bar fertilization technology compared to the conventional mixed fertilization. The research revealed that side bar fertilization technology could enhance the growth and output of summer corn. It turned out side bar fertilization treatment could increase 3.2%, 7.9% yield respectively than conventional mixed fertilization and no fertilizer treatment, and in some extent, side bar fertilization technology promoted and adjusted the soil water distribution.
