采用郑玉668为试验材料，在盆栽条件下研究了在普通尿素中添加不同形态锌对玉米生长和产量的影响。结果表明：在普通尿素中添加复合氨基酸螯合锌显著促进了玉米幼苗根部的发育，提高了玉米幼苗的叶绿素值，增加了玉米苗期的株高、干物重及单株穗粒重；普通尿素中添加硫酸锌对玉米生长和产量影响不显著。

In the present study, the effects of two types of zinc-supplemented urea on growth and yield perform-ance of corn plants were investigated using Zheng Yu 668 as a test corn cultivar under potted conditions. The re-sults showed that the development of corn roots could be significantly promoted by using the urea containing com-plex amino acid zinc chelate, as well as the enhancement of plant height, chlorophyll value, dry matter weight and kernel weight per ear. The application of the urea containing zinc sulfate had no significant effect on promo-ting the growth of corn seedlings.
