腐殖质

At the latter stage of sugarcane growth, total N, OM, Cl(superscript -) sugarcane fields are lower than in 75 ton treatment in sugarcane fields. Soil fertility, OM and HA content, and catalase and polyphenol oxidase activity are higher in the four vinasse treatments than in CK1 and CK2 treatments. Sugarcane plantation absorbs vinasse nutrient and purifies soil environment when treated with vinasse.

说明与施用化肥或不施肥处理相比，蔗地施用废液有提高土壤肥力和有机质、腐殖质含量的作用，但也使施用初期过氧化氢酶和多酚氧化酶活性异常升高，施废液的土壤种植甘蔗对废液养分吸收和环境净化有一定作用。

Under the different sowing seeds way the soil ulmin, the alkaline hydrolysis nitrogen, the fast-acting phosphorus content present the tendency which in 0-40cm various soil layers increases along with the soil layer depth reduces, take 0-10cm soil layer soil content as biggest; The change tendency which the colleague mixes broadcasts mixes with the interlacing broadcasts the change tendency which the lawn fast-acting potassium presents reduces, after the unicast awnless brome lawn presents falls first, increases again falls, take 0-10cm and 20-30cm soil layer soil content as biggest, is 80, and achieves the extremely remarkable difference with other soil layers between; pH presents increases the tendency.

混播草地上牧草根系死亡后，能在土壤中遗留大量的有机质，在土壤微生物的作用下形成土壤腐殖质，其中有丰富的氮、磷、钾等元素。无芒雀麦，又名禾萱草，无芒草，是世界上分布较广，应用较多的优良牧草；是草地补播和建立人工草地的理想草种。无芒雀麦生长快，竞争力强，在杂草较多的草荒地上种植，也能获得成功，为我国温带和寒温带建造人工草地的当家草种。

But studies suggest that marine humic materials have a different origin and hence a different structure.

但是研究建议海洋腐殖质的材料有一不同起源和因此一不同结构。

The mechanism for methylation of mercury in presence of humic substances was studied.

4对腐殖质存在下汞非生物甲基化作用的机理进行初步探讨。

In a narrow sense, soil organic matter is the soil humus and its components are humic acid, fulvic acid and humin.

从狭义上讲，土壤有机质就是土壤腐殖质，其组分有胡敏酸、富里酸和胡敏素。

The results show that humin occupies two thirds of the organic matter, which is the dominant part of the organic matter, whereas fulvic acid and humic acids occupy one third of the organic matter, which exert strong geochemical effects.

发现有机质主要由胡敏素组成，其含量可占有机质的2/3左右，地球化学活性很强的富里酸和胡敏酸占腐殖质总量1/3左右。

And humic substance (fulvic acids, humic acids and humin). The features of fulvic acids of humic substance at the southwestern part of Turfan-Hami basin are: the content of C is low, and the content of H, S, O is relatively high, atomic number of C/H is low.

研究证实吐哈盆地腐殖质中黄腐酸的特点是C含量较低，H、S、O含量偏高，C/H原子数比较低；官能团分析证实黄腐酸的总酸基、羧基、酚羟基含量较高，反映出黄腐酸具有较高的活性。

The results showed that: three major peaks,humuslike fluorescence peak A,proteinlike fluorescence peaks B and C appeared on the threedimensional fluorescence spectroscopy;the DOM fluorescence intensity was well related with DOC and CODMn,indicating that fluorescence dissolved organic matter content can reflect both the organic carbon content and the organic matter content by oxidation in the water in August,during the nonalgae bloom outbreak period,fluorescence intensity had a poor correlation with chlorophyll a,indicating that phytoplankton was not the main source of the fluorescent substances.

结果显示：小江回水区DOM的三维荧光光谱主要表现出3个峰，类腐殖质荧光峰A、类蛋白荧光峰B和C；DOM荧光强度与DOC、CODMn相关性较好，表明荧光溶解有机物质的含量可以较好反映水体中有机碳和可被氧化有机物的含量；在8月份非水华暴发时期荧光强度和叶绿素a相关性较差，表明DOM荧光物质主要不是由浮游植物产生。

Pipe and growing in woodland humus of eastern North America; in some classifications placed in a separate genus Hypopitys.

一种肉质的茶色或微红色腐生草本植物，类似印第安烟管，生长在北美东部的腐殖质林地中；有时被归入松下兰属。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
