为提高烤烟产质量,探究连续施用生物炭的长期效应,以云烟87为试验材料,通过3年定位试验,研究连续施用生物炭对烤烟黑胫病、干物质量和产质量的影响。结果表明,连续施用生物炭能降低烤烟黑胫病的发病率(降低2.78 %~ 8.33%)及病害指数(降低1.39 %~ 4.40%) ,但其对病害的抑制作用随着连作时间的延长逐年降低;连续施用生物炭有利于烤烟根系的干物质增加(增加19.50 ~ 43.02 g) ,总干物质积累量在2015、2016年均有所增加(增加40.50 ~ 85.20 g) ,但在2017年时略有降低(降低20.00 g) ;连续施用生物炭能提高烤烟的产质量,烤后烟叶的上等烟(增加2.60 %~ 8.91%) 、中上等烟比例(增加0.51 %~ 3.67%)及经济性...

In order to improve the yield and quality of flue-cured tobacco,and study the long-term effects of continuous application of biochar,yunyan 87 was selected as testing material and a three-year located experiment was designed to study the effects of continuous application of biochar on black shank,dry matter and yield and quality. The results showed that the continuous application of biochar could reduce the morbidity of disease (decreased by 2.78% ~ 8.33%) and disease-infected indices (decreased by 1.39% ~ 4.40%) of flue-cured tobacco,but its i...
