病狀為葉片變白、腐爛或形成不規則孔洞。防治措施：下調養殖水層。For weeks at a time they would hold on steadily, day after day ; and for weeks upon end they would camp, here and there, the dogs loafing and the men burning holes through frozen muck and gravel and washing countless pans of dirt by the heat of the fire
有時他們會一天接一天，一連走好幾個星期；有時則隨處扎營，停留幾個星期，人們用火在凍結的腐殖土和沙層上鉆洞，淘洗數不清的盤盤泥沙，狗則無所事事地閑逛。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
