研究木醋液高值利用的有效途径。通过田间种植试验,选择利用生物质热解工艺制取的不同浓度的木醋液对芹菜进行分类型、分批次的叶面喷洒,并以清水为对比,研究叶面喷洒木醋液对芹菜产量和品质的影响。结果表明:叶面喷洒木醋液能提高芹菜的株高和产量,其中喷洒稀释300倍((V(水)∶V(木醋液)=300∶1))的木醋液可提高芹菜产量17.12%;叶面喷洒木醋液能提高芹菜的VC含量且不会增加芹菜中硝酸盐的含量,其中喷洒稀释300倍的木醋液对提高芹菜的VC含量达到25.6%;叶面喷洒木醋液对芹菜植株氮磷钾吸收没有显著影响。
The effective way to study the high use of wood vinegar. Through field cultivation experiments, we chose to use different concentrations of wood vinegar prepared by biomass pyrolysis process to separate the celery leaves into different types and batches, and compare the effect of foliar spraying wood vinegar on celery The impact of yield and quality. The results showed that the spraying of wood vinegar could increase the plant height and yield of celery. Spraying wood vinegar diluted 300 times (V (water): V (wood vinegar) = 300: 1) 17.12%. The spraying of wood vinegar with foliar spray increased the VC content of celery and did not increase the content of nitrate in celery. The spraying of 300 times diluted wood vinegar increased the VC content of celery to 25.6% Liquid had no significant effect on the absorption of nitrogen, phosphorus and potassium in celery plants.
