【摘要】：[目的]为了研究不同生物质炭用量和类型对汉中烤烟生长发育和产量产值的影响。[方法]2013年5~9月,在陕西省汉中市南郑县小南海镇布置田间小区试验,研究了不同的生物炭用量和类型下的各个生育时期烟叶农艺性状、产量和产值进行了比较分析。[结果]施用生物质炭可明显增加烟叶生育中前期株高、茎围和叶片大小,增加烟叶产量、产值和中上等烟叶比例。随着生物炭施用量的增加,烟叶备生育时期农艺性状均显著改善,产量、产值和中上等烟叶比例叶明显增加,且在施用量为900 kg/hm~2时达到最高。稻壳炭和麦秆炭对改善烟叶农艺性状明显优于花生壳炭,稻壳炭更有利于旺长期叶片及现蕾期茎秆的发育,而麦秆炭有利于提高旺长期株高和有效叶数以及现蕾期叶片的发育,且施用稻壳炭提高烟叶产量和产值的效果最好。[结论]施用生物炭是汉中烟区改良植烟土壤、促进烟叶生长发育的有效措施,生物炭施用量宜控制在每亩穴施600~900 kg/hm~2左右,可优先选择稻壳炭作为土壤改良的材料。
[Abstract]:[objective] to study the effects of different biomass carbon levels and types on the growth and output value of flue-cured tobacco in Hanzhong. [methods] A field plot experiment was conducted in Xiaonanhai Town, Nanzheng County, Hanzhong City, Shaanxi Province from May to September 2013. The agronomic characters, yield and output value of tobacco leaf at different growth stages were studied under different biochar levels and types. [results] Biomass charcoal application could significantly increase plant height, stem circumference and leaf size, yield, output value and the proportion of upper and middle tobacco leaves in the middle and early stage of tobacco growth. With the increase of the application rate of biochar, the agronomic characters of tobacco were significantly improved, the yield, the output value and the proportion of the upper and middle tobacco leaves were obviously increased, and reached the highest level at 900 kg / hm ~ 2. Rice husk charcoal and wheat stalk charcoal were superior to peanut husk charcoal in improving agronomic characters of tobacco leaves. Rice husk charcoal was more favorable to the development of leaves and stems in bud stage, while wheat straw charcoal could increase plant height and effective leaf number and leaf development in bud stage. The effect of applying rice husk charcoal on tobacco yield and output value was the best. [conclusion] Biochar application is an effective measure to improve tobacco planting soil and promote the growth and development of tobacco leaves in Hanzhong tobacco area. The amount of biochar application should be controlled at about 600,900 kg/hm~2 per mu, and rice husk charcoal can be selected as the material for soil improvement.
