摘要
通过乙酸乙酯萃取-旋转薄膜蒸发-丙酮萃取-旋转薄膜蒸发精制松木屑木醋液并进行气相色谱-质谱(GC-MS)分析,结果表明相对含量最高的化合物是苯酚(18.92%).木醋液的稀释液种子萌发实验结果表明,稀释倍数为 2000 倍时,萝卜和菠菜的发芽率与对照组差异极显著,分别为96%和97%,而对照组的发芽率分别为 82%和 83%,处理组的发芽率均比对照组高;稀释倍数为100 倍时,萝卜和菠菜的发芽率与对照组差异极显著,均只有3%,均比对照组低.
Abstract
The pine sawdust wood vinegar was refined through ethyl acetate extraction,rotating film evaporation,acetone extraction,and rotating film evaporation,and analyzed by gas chromatography-mass spectrometry(GC-MS).The results showed that the compound with the highest relative content was phenol(18.92%).The results of the seed germination experiment with the dilution of wood vinegar showed that when the dilution ratio was 2000 times,the germination rates of Raphanus sativus and Spinacia oleracea were significantly different from the control group,with 96%and 97%,respectively.The germination rates of the control group were 82%and 83%,respectively.The germination rates of the treatment group were higher than those of the control group;When the dilution ratio was 100 times,the germination rates of Raphanus sativus and Spinacia oleracea were also significantly different from the control group,both only 3%,both lower than the control group.
