soil humic acid meaning in English
土壤腐殖酸
Examples
- Using corn straw and soybean straw , the characteristics of the decaying process and the remainders , the difference of soil fertility status and soil humic acids character in different using ways are studied by normal analysis combined with energy analysis , thermal analysis ( dta , tg , dig ) and infrared spectrum analysis ( ftir )
本文以玉米秸和大豆秸为腐解材料，通过常规分析方法结合能态分析、热分析( dta 、 tg 、 dtg )和红外光谱( ftir )分析研究了荒漠绿洲生态系统下残体的腐解特征以及不同利用方式下土壤养分和土壤腐殖质的变化。 - Desert and oasis ecosystem are the main ecosystems in arid area . studying the characteristics of decaying process , decaying remainders and soil humic acids can accumulate the first hand data for studying the accumulation and decomposition of soil organic matter , the situation of soil fertility , substance cycling and energy flowing in desert - oasis ecosystem , and has the great significance on desert ecosystem restraint and oasis ecosystem extension
研究荒漠绿洲生态系统中植物残体在土壤中的腐解过程及腐解物和腐殖物质的特征，可为研究荒漠绿洲生态系统中土壤有机质的累积和分解、土壤肥力状况和荒漠绿洲生态系统的物质循环和能量流动积累宝贵的第一手资料，对于抑制荒漠生态的恶化，促进绿洲生态的发展具有重要意义。 - An improved method for extraction of soil humic acid was used to isolated dissociative humic acid ( ha - i ) and enwrapped humic acid ( ha - ii ) from paddy soil and pohakee peat . quantified and characterized ha - i and ha - ii with 13c nmr , py - gc - ms , optical and elemental analysis . the results indicate that two humic acids are highly different in structure , and ha - ii is more condensed
采用一种改进的腐殖酸萃取方法从珠江三角洲稻田土壤和pahokee泥炭中分离出了游离腐殖酸( ha - )和包裹腐殖酸( ha - ) ，并采用元素分析、 ~ ( 13 ) cnmr 、 py - gc - ms和有机岩石学方法对ha -和ha -进行了定量和定性研究，结果表明两种腐殖酸在性质和结构上是有区别的。
