| 摘 要： | 为探索在常规施肥基础上增施生物炭对植烟土壤肥力及烤烟生长的影响，采用大田试验研究不增施生物炭（CK）、烤烟季和冬春季均增施生物炭（T1）和仅烤烟季增施生物炭（T2）不同处理下的土壤和烤烟生长的相关指标。结果表明，增施生物炭可显著提高土壤pH与速效养分含量，T1处理表现最好。增施生物炭显著提高土壤的MWD、GMD和>0.250mm粒级团聚体含量，但T1和T2处理差异不显著。T1处理的株高、最大叶长、叶宽、叶面积以及根和叶的干物质积累量最优，T2处理的茎围和茎的干物质积累量最大。因此，烤烟季和冬春季均增施生物炭的处理效果更佳。

| Abstract: | In order to explore the effects of adding biochar on soil fertility and flue-cured tobacco growth on the basis of conventional fertilization, a field experiment was conducted to study the related indexes of soil and flue-cured tobacco growth under the conditions of no application of biochar (CK), application of biochar both in flue-cured tabacco season and winter and spring seasons (T1) and only adding biochar in flue-cured tobacco season (T2). The results showed that adding biochar could significantly increased soil pH and the contents of available nutrient, and the effects of T1 treatment were the best. Application of biochar significantly increased MWD, GMD and particle size aggregates larger than 0.250mm, but there was no significant difference between T1 and T2 treatments. The plant height, maximum leaf length, leaf width, leaf area and the dry matter accumulation of root and leaf were the best in T1 treatment, and the stem girth and stem dry matter accumulation were the largest in T2 treatment. Therefore, the effects of adding biochar in flue-cured tobacco season and winter and spring are better. |
