摘要
一、绪言 在自然界中各种植物所能适应环境条件的幅度,有大有小。就植物与土壤性质的关系来说,有些植物只能生长在酸性土上,从不见于盐渍土或钙质土上,这些植物就叫做酸性土指示植物。另一些植物只能生长在有碳酸钙反应的或合有碳酸钙胶体的土壤上,这些植物就是钙质土指示植物。
Chemical composition of plants,including 31 species of oxylophytes,31 species of calciphytes,and 43 species of halophytes,growing on various parts of China,have been examined.Only leaves or pinnas of the plants were collected.Determinations were made to the ash,nitrogen,sulfur,phosphorus,aluminum,iron,potassium,sodium and calcium contents of the plants.In addition,the water soluble SO_(4)^(=),CI^(-),HCO_(3)^(-)of certain halophyteswere also determined.It appears that the chemical composition of plants of the same ecological type is closely related to their taxonomic features.However,it shows significantly that the plants growing on the same soil type possessed more or less common chemical characteristics(Table 5).
