【摘要】：为寻求陕南烟田适宜的土壤改良技术,采用生物炭与菜籽饼二元配比试验,研究其对土壤矿质养分及烟叶品质与产量的影响。研究结果表明:生物炭与菜籽饼均有利于提高土壤矿质养分含量,且以混合施用效果更显著。生物炭与菜籽饼能有效促进烤烟生长,改善烤烟农艺性状,增加上、中部烟叶面积且随菜籽饼施用量的增加叶面积呈现增大的趋势。上等烟和中上等烟比率随生物炭施用量的增加呈先增加后降低的趋势;而产量与产值则随菜籽饼用量的增加表现出增大的趋势。生物炭和菜籽饼及二者交互对烤烟化学品质提升效果显著,能有效提高烤烟全氮、烟碱、钾及总糖和还原糖含量,降低烤后烟叶淀粉水平。综合分析,在陕西安康市旬阳地区推荐生物炭与菜籽饼配比为生物炭750 kg/hm2+菜籽饼750 kg/hm2。
[Abstract]:The effects of biochar and rapeseed cake on soil mineral nutrients, tobacco quality and yield were studied in order to find a suitable soil improvement technique in southern Shaanxi tobacco field. The results showed that both biochar and rapeseed cake were beneficial to increase the content of mineral nutrients in soil, and the effect of mixed application was more obvious. Biochar and rapeseed cake can effectively promote the growth of flue-cured tobacco, improve the agronomic characters of flue-cured tobacco, increase the middle tobacco leaf area and increase the leaf area with the increase of rapeseed cake application rate. The ratio of upper and middle grade tobacco increased first and then decreased with the increase of the application rate of biochar, while the yield and output value increased with the increase of the amount of rapeseed cake. Biochar, rapeseed cake and their interaction could improve the chemical quality of flue-cured tobacco, increase the contents of total nitrogen, nicotine, potassium, total sugar and reducing sugar, and decrease the starch level of flue-cured tobacco leaf. The ratio of biochar and rapeseed cake was recommended as 750kg / hm ~ (2) kg/hm2 rapeseed cake in Xunyang area, Ankang city, Shaanxi province.
