主 题：Flue-cured tobacco Biochar Soil improvement Quality
摘 要：This study was conducted to study the feasibility of biochar in soil im- provement and tobacco quality. The black soil in NinganCountry of Mudanjiang was used as the material in this study, and the effects of biochar on tobacco-planting soil C/N, soil microorganisms, the development of tobacco, and chemical compo- nents and neutral aroma components in flue-cured tobacco werestudied. The results showed that the application of biochar at a rate of 1 800 kg/hm2 could increase soil C/N by 31.79%, and the quantity of actinomycetes in the soil was 3.8 times as much as that in control. The growth wasobviously better after biochar application, plant height and effective leaf number were significantly higher than those ofcontrol, but total sugar and nicotine were not significantly different. The application of biochar at a rate of 1 200 kg/hm2 increased the potassium content by 11%, the application of biochar at a rate of 2 400 kg/hm2 improved total sugar content by 5.40%, and the application of biochar at a rate of 1 800 kg/hm2 made the tobacco solanone content 1.97 times as that of control. Comprehensive studies showed that the application of biochar 1 200-1 800 kg/hm2 could improvesoilenvironment, and promote tobacco growth and quality.
