The organic litter will help to cushion trampling forces, limit the compactability of soils, release plant nutrients, and reduce the erosie forces of rainfall.
这些有助于缓冲踩踏地面的力量,避免土壤的结块成形,释放植营养,而且减少降雨的腐蚀。
The measuring method of sand compactability in laboratory is analyzed,and a fast measuring method is designed,and the intelligent instrument for fast measuring sand compactability are developed.
