本文对霉菌生长前后黄腐酸结构及其对植物生长的刺激作用进行了考察,结果表明,霉菌生长后,黄腐酸溶液的植物生长刺激作用变差。对霉菌生长前后黄腐酸的红外图谱的比较显示,霉菌具有促进黄腐酸向黑腐酸转变的趋势。
In this paper, the structure of fulvic acid before and after mold growth and its stimulating effects on plant growth were investigated. The results showed that the growth stimulating effect of fulvic acid solution was worse after mold growth. Comparing the FT spectra of fulvic acid before and after mold growth showed that the mold had the tendency to promote the conversion of fulvic acid to fulvic acid.
