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Fescuearundinacea是一种适应江南地区绿化种植的冷季型草坪草。运用不同质量不同粒径的竹炭施洒于高羊茅草坪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,水解氮、有效磷、速效钾、交换性钙和镁等元素含量均明显提高,而有效锌和铜等金属含量则相对降低;竹炭对高羊茅的发根、发叶及生长也有不同程度的促进作用。施炭量200g·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和根、茎、叶增长量最佳。
Bamboo charcoal is kind of porous quality,containing many kinds of inorganic compounds,new materials of relatively big specific area.Fescue arundinacea is that one kind adapts to the south area in China and afforests the type lawn of cold season that plants.Bamboo charcoal to be constructed and shed in F.*'arundinacea lawn top layer soil by utilize different quantity different particle size.The result showed:Having constructed the soil of the bamboo charcoal,its physics and chemistry performance had obviously improved contents of element,such as N,P,K,Ca,Mg,etc.,and Zn,Cu,heavy metal content reduced.F.*'arundinacea taking root,taking leaf and grow had influenced in varying degrees.And the way a crop was growing,root,stem of F.*'arundinacea had also the best by constructing 200 g·m^(-2) of charcoal quantity,charcoal soil improvement of bamboo that a diameter was smaller than 3 mm of charcoal.
