尿素配合物微量元素肥料的合成

Synthesis of Coordination Compounds Made of Urea and Trace Element

用铁、锰、铜、锌的硝酸盐分别与尿素反应 ,合成了四种固体配合物。它们均易溶于水。根据物质结构理论 ,这些金属离子与尿素中的氮原子发生了配位 ,使金属更易被植物吸收 ,使氮缓释。因而合成的此类配合物不仅是优良的微量元素肥料 ,而且也是一种长效的氮肥。

The four kinds of solid coordination compound are synthesized making ironic nitrate,manganes nitrate,copper nitrate,zinc nitrate react with urea respectively.The compounds dissolve in water easily.coordination reaction have taken place between these metal ions and nitrogen in urea,making the plants absorb these metals more easily and release nitrogen slowly.From this we see that,these coordination compounds are nit only good fertilizer containing trace elements,but also nitrogenous fertilizer with long fertility.
