Biological absorbing capacity of nutrient elements by some temperate tame grasses

摘要：

The biological absorption coefficient (Ax) is a useful way to evaluate the ability of a plant to absorb certain elements.The index expresses the flux of the chemical element in the soil‐plant system and reflectes the selective absorbing capacity of the plant on for the particular.Biological absorbing capacity of 10 elements in 6 grasses was studied at mountainous region of north subtropical zone of China in this paper.These provided a scientific basis for managing artificial grassland.
