枯草层是草坪草已经死去的茎叶、根系堆积起来而形成的新鲜未分解的枯萎半腐烂的有机物,它就犹如一层紧实的编织物处于地表与绿色植物之间。枯草层分两层,上层是横向生长的茎叶和刚腐烂的植物体;下层是像泥炭一样难以分解的底层。
The hay is the dead, undeveloped stem and leaves of turf grasses, the fresh undissolved withered, half-rotten organic matter that builds up in the roots and acts like a tighter braid between the earth’s surface and the greenery. The grass is divided into two layers, the upper is the horizontal growth of stems and leaves and just rotten plants; the lower is peat as hard to break down the bottom.
