摘　　要：采用盆栽试验,研究3种增效氮肥(海藻寡糖尿素、腐植酸尿素、聚能网尿素)及其用量对玉米幼苗生长、光合特性及养分吸收的影响。结果显示,3种增效尿素对玉米幼苗生长的促进作用均好于普通尿素,且海藻寡糖尿素对玉米生长的综合促进效果最优;进一步研究显示,海藻寡糖尿素可提高玉米功能叶片叶绿素含量和净光合速率,还能促进玉米对氮、磷、钾的吸收,同等施氮条件下其施用效果优于其他2种增效氮肥。The effects of three kinds of synergistic nitrogen fertilizers （alginate oligosaccharide urea, humic acid urea, binding energy network urea） and different amounts on growth, photosynthetic characteristics and nutrient uptake of maize seedlings are studied based on pot experiments. The results show that the promoting effects of applying three kinds of synergistic urea on the growth of maize seedlings are better than that of common urea, the comprehensive promoting effects of alginate oligosaccharide urea is optimum; Further studies show that alginate oligosaccharide urea improves chlorophyll content and net photosynthetic rate of function leaves, and promotes the absorption of nitrogen, phosphorus and potassium of maize seedlings, which is better than that of other two synergistic nitrogen fertilizers at the same nitrogen level.
