查询词典 juncus

Based on plant morphological traits, some types of strategies could be divided. The regeneration strategies of three species, Eriocaulon buergerianum, Juncus articulatus and Sagittaria potamogetifolia, had characteristics of r-strategists, and Oryza rufipogon, Scirpus triangulatus and Eleocharis plantagineiformis had characteristics of K-strategists.

根据植物的功能形态学特征，可以分出一些生活史对策类型，如从种子特征来看，谷精草、小花灯心草和小慈姑等植物的更新对策具有明显的r-对策特点，粉被苔草、野荸荠和普通野生稻等具有一定的K-对策特点；依据成株特征也可以区分出竞争、躲避或耐压对策的定居对策类型。

The results showed that the critical values of Cd,Pb,and Cu in the Juncus Effuses grown soil were set at 10,100 and 100mg kg-1 respectively,but Juncus Effuses was not able to grow in the Zn polluted soil.

结果表明：种植灯心草土壤中的Cd、Pb、Cu三种重金属临界值可分别设定为10mg kg-1、100 mg kg-1、100mg kg-1。灯心草不适合在Zn污染的土壤中种植，土壤中As临界值尚需作进一步的研究来确定。
