对过氧化氢氧化风化煤获得黄腐酸及其抗旱生理活性进行了研究。考察了过氧化氢浓度、氧化处理时间和液煤比对黄腐酸溶液浓度的影响,得出了获得高浓度黄腐酸的最佳氧化条件。初步的抗蒸腾生理活性实验数据显示:喷施100mg/L的黄腐酸能使小麦的蒸腾速率降低,这表明过氧化氢氧化风化煤获得的黄腐酸具有抗蒸腾作用,但喷施黄腐酸后的第七天黄腐酸的抗蒸腾效应消失。
The study on the fulvic acid and its drought-resistant physiological activity of oxidizing coal by hydrogen peroxide was studied. The effects of hydrogen peroxide concentration, oxidation treatment time and liquid coal ratio on the concentration of fulvic acid solution were investigated. The optimal oxidation conditions for the high concentration fulvic acid were obtained. Preliminary experimental data of anti-transpiration physiological activity showed that 100 mg / L fulvic acid could reduce the transpiration rate of wheat, indicating that fulvic acid obtained from hydrogen peroxide oxidation weathered coal had anti-transpiration effect. However, The anti-transpiration effect of fulvic acid disappeared on the seventh day after acidification.
