用法和例句

This paper studied the optics character of organic matter content,composition and form of humus and the RF,ΔlogK of humic acid at different planting age of Heilu soil in Longdong loess plateau.

综合研究了陇东黄土高原黑垆土不同烟草种植年限土壤的有机质含量、腐殖质组成、形态及胡敏酸的色调系数、相对色度等,结果表明:30~70 cm土层土壤有机质含量演化随烟草种植年限的增加表现出降低的特征最为明显,土壤表层的有机碳与胡敏酸含量则呈正相关,连作23年的胡敏酸最低。

The composition and morphology of organic matter and Humus acid from the tone coefficient (△ log K) and changes of relative color RF analysis shows that: natural pine forest could reduce the humus degree and ability to form the better soil structure.

从腐殖质的组成、结合形态以及由不同结合形态胡敏酸的光密度曲线、胡敏酸的色调系数(△logK)和相对色度(RF)变化综合分析表明:油松林植被使土壤的腐殖化程度减弱,对形成良好的土壤结构的能力下降,表层土壤的氧化稳定性及土壤腐殖质的品质降低。
