腐殖质

In the South of Hunan with cigarette-rice multiple cropping, the pH is medium and high, the organic matter is high, but the humus content is low in the organic matter; N and Zn are abundant, P is very scarce, about 60% of soils is lack of B seriously.

以年内烟－稻复种连作为主的湘南烟区，土壤pH偏高，有机质含量高，但有机质中腐殖质的比例较低；土壤中的氮和锌比较丰富，钾很缺乏，有近60％的土壤严重缺硼。

With the extension of fertilization with organic , especially with the combination with organic and inorganic fertilizer,the soil readily oxidizable organic matter increased, while Kos decreased ; The soil active humus content, humus acid and E4/ E6 value were increased , while molecular weight and aromaticity of humus acid were decreased , thus progress to humus formation and quality of organic matter were enhanced.

随着有机肥特别是有机无机氮肥配施的年限延长，土壤易氧化有机质的含量逐渐增加， Kos 下降；提高了土壤松结态腐殖质含量，提高胡敏酸的比例；提高胡敏酸的E4/ E6值，降低土壤胡敏酸的分子量及芳构化程度；从而促进土壤腐殖化进程，改善有机质的品质。

Soil oxidoreductase is a group of enzymes catalyzing many important soil biochemical reactions and concerning with the transformation of soil organic matter,formation of humic substance,and dynamics of soil fertility.

土壤氧化还原酶是存在于土壤中的一种重要酶类，参与土壤中为数众多的重要生物化学反应，与土壤中有机物质的转化、腐殖质的形成以及土壤肥力变化密切相关。

Humus or peat moss will work quite well.

腐殖质泥炭藓还是会不错。

Two parts soil should be mixed with one part humus leaf or manure compost, peat moss, pine bark, etc.

两部分土壤应混合一部分腐殖质（叶或粪便堆肥，泥炭，树皮等）。

Not tall to edaphic requirement, be fond of the relief tall dry, small acidity soil that contains a lot ofhumus, blame with earthy layer the sandiness soil with fecund and deep, wet, good drainage is most appropriate.

富含腐殖质的微酸性土壤，尤以土层深厚。肥沃湿润。排水良好的沙质土壤最为适宜。

Dual-core is a saprophytic orchid plants, was born in an altitude of 700-800 meters deep oak forest humus soil.

双蕊兰是腐生植物，生于海拔700-800米的柞林下腐殖质深厚的土壤。

There were no significant differences in soil bacterial and fungal biomass, total nematode density and diversity, herbivore density, bacterivore density and omnivore-predator densities between the trenched and control plots in both mineral and humus soil layers.

切根处理对腐殖质层和矿质土层的细菌和真菌生物量、线虫总密度和多样性、植食性线虫、食细菌线虫和捕食与杂食性线虫的密度均没有显著影响。

The results show that total N, Cl(superscript -), organic matter, humic acid content of soil improves under vinasse treatments. Catalase and polyphenol oxidase activity increase abnormally at sugarcane settling stage and then sharply decrease to CK2 level at sugarcane maturity stage.

结果表明：蔗地施用废液提高了土壤全氮、Cl、有机质、腐殖质含量，使甘蔗苗期土壤过氧化氢酶和多酚氧化酶活性异常升高，随后迅速下降，成熟期下降到接近或小于CK2的土壤酶活性水平。

The results show that total N, Cl-, organic matter, humic acid content of soil improves under vinasse treatments. Catalase and polyphenol oxidase activity increase abnormally at sugarcane settling stage and then sharply decrease to CK2 level at sugarcane maturity stage.

结果表明：蔗地施用废液提高了土壤全氮、Cl-、有机质、腐殖质含量，使甘蔗苗期土壤过氧化氢酶和多酚氧化酶活性异常升高，随后迅速下降，成熟期下降到接近或小于CK2的土壤酶活性水平。

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。
