【摘要】 竹炭是一种多孔性、含有多种无机物、比表面积大的新型材料。高羊茅是一种适应江南地区绿化种植的冷季型草坪。本文运用不同质量不同粒径的竹炭施洒于高羊茅草种表层土壤中进行试验,结果表明:施过竹炭颗粒的土壤,其理化性能得到了改良,水解N、有效P、速效K、交换性Ca和Mg等元素含量均明显提高,而有效Zn和Cu等金属含量则相对降低,高羊茅的发根、发叶及生长也有不同程度的促进作用;并以施炭量200 g·m-2、炭粒直径小于3mm的竹炭对土壤改良效果和高羊茅的长势、根、茎叶增长量最佳。更多还原

【Abstract】 The bamboo charcoal is a kind of porous quality, contain many kinds of inorganic compounds, new materials of relatively big specific area . The high sheep cogongrass (Fescue arundinacea) is that one kind adapts to the South area and afforests the type lawn of cold season that plants. Bamboo charcoal to be constructed and shed in the high sheep cogongrass (Fescue arundinacea) lawn top layer soil by utilize different quantity different particle size, The result shows: Having constructed the soil of the bamboo charcoal, its physics and chemistry performance has obviously improved contents of element, such as N, P, K, Ca, Mg,etc., and Zn, Cu ,heavy metal content reduce. The high sheep’ cogongrass (Fescue arundinacea) taking root, taking leaf and grow have influenced in varying degrees. And The way a crop is growing, root, stem of the high sheep cogongrass (Fescue arundinacea) have also the best by constructing 200 g · m-2 of charcoal quantity, charcoal soil improvement of bamboo that a diameter is smaller than 3 mm of charcoal.更多还原
