了解、研究乔灌木中的营养元素含量以及它们间的相似性,对于林木引种、栽培管理具有十分重要的意义。早在18世纪,李比希(Tustus vonLiebig)认为,植物分析可作为估量植物对营养元素需要的一种方法。我国的植物学家侯学煜也认为。在研究植物成分和土壤化学组成相互关系时,可以理论上找出某种植物,只能生长在某种土壤上的原因,进而可知在什么土壤上栽植什么树种较适宜。苏联学者证明,植物选择吸收某种元素是和本
Understanding and studying the nutrient elements in the shrub and shrubs and the similarities among them is very important for the introduction and cultivation management of trees. As early as the eighteenth century, Tustus von Liebig argues that plant analysis can be used as a measure of the plant’s need for nutrients. Hou Xueyu botanist in China also think. When studying the relationship between the composition of plants and the chemical composition of soils, one can theoretically find the reason why some plants can only grow on some soils, and then what kind of trees are planted on which soil is more appropriate. Soviet scholars have proved that plants choose to absorb certain elements of this and
