1Influence of lanthanum level and interactions with nitrogen source on early development of Juglans nigra显示文摘稀土元素元素在中国农业被用于 30 年改进生长和产量。众多的科学研究在生理学,矿物质营养,和生长显示出改进,尽管有害效果可以也发生。很少的研究在木质的种类上被执行了。我们指数地使肥沃一个年旧黑核桃(Juglans nigra L.) 有 0, 0.1, 1, 10,或 100 mg 镧(La ) 和 800 mg 氮(N) 的幼苗作为 NaNO3,(NH4 ) 2SO4, NH4NO3,或没有 N。一月追随者期末考试授精,生长,矿物质营养,光合作用,叶绿素,和硝酸盐 reductase 活动被估计。植物与 La 的高水平使肥沃减少了好根生长,镁的集中,钙,镍,和磷,光合作用层次,和叶绿素一个内容。叶的 La 集中显示出相互作用效果,与乘在在到给 10 mg La 为的那些的 100 mg La 喂的植物的更大的集中的三~四(NH4 ) 2SO4 和 NH4NO3 处理。在层次的 La 增加的建议不有益的效果在在 N 之间的这研究和相互作用使用了的结果采购原料, La 层次没在黑核桃幼苗的生长,矿物质营养,或生理学上有重要影响。Nicodemus Michael A Salifu K Francis Jacobs Douglass F 2009Journal of Rare Earths2009,27,2:4
