腐殖質層
英文
h layer humus layer-
The black earth is a kind of alfisol, with a thick layer of humus, loose texture, high fertility, high porosity ratio, poor permeability and a high content of clay, which is suitable for cultivation
摘要黑土是一種腐殖質層厚,質地鬆散,肥力很高,孔隙比較大而透水性差,粘粒含量高,適于耕作的淋溶土。The defining feature is the gley horizon below the humus - blue - grey clay whowe color is due to ferrous iron compounds that have been reduced by microorganisms, flecked with localized areas of rust - colored oxidized ferric compounds
潛育土的一個重要特點是位於土壤腐殖質層之下,其土層呈灰藍色是由於含有被微生物還原的亞鐵離子,而且常有部分鐵被氧化生成紅棕色的銹斑。The results showed : the relationships among cover of herbaceous layer, cover of liver moss layer, thickness of liver moss layer, thickness of root system twine layer and the distance between seedlings and adjacent tree were positive correlation ; the relation between litter and tile above five variables were negative correlation ; the variables of micro - habitat affecting seedling in the picea schrenkiana stand were generalized with moss, herbaceous, spatial distance, humus and litter ; litter and spatial distance between seedlings and adjacent tree were the most primary factors of micro habitat affecting regeneration of one year seedling
結果表明:天山雲杉林分中草本層蓋度、苔鮮層蓋度、苔鮮層厚度、根系盤結層厚度、幼苗距大樹的距離5個環境變量之間為正相關;枯落物與草本層蓋度、苔蘚層蓋度、苔蘚層厚度、根系盤結層厚度、幼苗距大樹的距離為負相關;天山雲杉林微生境綜合因子可概括為「苔蘚」 、 「草本」 、 「空間距離」 、 「腐殖質」和「枯落物」 ;影響一年生幼苗更新最主要的微環境綜合因子為「枯落物」和幼苗距大樹的「空間距離」 。Change rules of soil p and k were complex, and their content was mainly related to parent material. from soil biological properties analysis, soil bacteria, fungi, actinomycetes and total of microbes in the topsoil were higher than in the bottom layer
各林地土壤腐殖質、胡敏酸和富里酸含量表層大於底層,在土壤腐殖質組成中, fa含量大於ha ,由於富里酸移動性較胡敏酸強, ha fa表層大於底層。The results of these work indicated that som in top soils and sediments are highly heterogeneous and conprise a wide range complex organic matter such as humic acid, kerogen, and black carbon, and som have a nice bit of black carbon
綜上所述,表層土壤和沉積物中的有機質是高度非均質的,包括腐殖酸、乾酪根和碳黑,並且碳黑具有相當高的含量。碳黑在來源、性質和結構上不同於腐殖酸和乾酪根,它是生物體和化石燃料不完全燃燒產生,具有更加穩定的性質和結構。分享友人
