摘要
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。
Field experiment for the influence of wood vinegar,made from the residue of biomass pyrolysis process,as leaves fertilizer on yield and quality of celery was conducted.The results showed that wood vinegar spraying can increase the yield and quality of celery.Spraying wood vinegar with 300 times diluted can enhance the yield and VC content of celery to 17.2% and 25.6%,respectively.Spraying the wood vinegar can decrease the chlorophyll content and will not increase the content of nitrate content in the celery...
