为探索废弃烟梗作为烟草漂浮育苗基质原料的可行性,用自制的烟梗草炭(TSP)为烟草栽培基质,进行了烟草漂浮育苗试验。结果表明:TSP 1号(烟梗草炭50%+天然草炭50%)、TSP 2号(烟梗草炭50%+椰糠50%)、TSP 3号(烟梗草炭50%+天然草炭25%+椰糠25%)均可替代天然草炭用于烟草漂浮育苗基质中,其中TSP 3号替代的效果较好,烟苗综合长势优于天然草炭配方基质;烟梗草炭1号和2号替代天然草炭育苗,其烟苗长势均与天然草炭配方基质相当。因此,利用废弃烟梗替代天然草炭作为烟草漂浮育苗基质的方法可行。
In order to explore the feasibility of using waste tobacco stems as raw material for tobacco floating seedling, the tobacco seedling raising experiment was carried out by using self-made tobacco stems and peat (TSP) as tobacco planting substrate. The results showed that TSP 1 (50% of tobacco straw peat + 50% of natural peat), TSP 2 (50% of tobacco straw peat + 50% of coconut bran), TSP 3 (50% Coconut bran 25%) can replace natural peat in tobacco floating seedling matrix, of which TSP 3 substitution effect is better, the comprehensive growth of tobacco seedlings is better than natural grass carbon formulation matrix; tobacco straw peat 1 and 2 to replace natural peat Nursery, the tobacco seedlings are growing with the equivalent of natural peat recipe matrix. Therefore, the use of abandoned tobacco stems instead of natural peat as tobacco floating seedling substrate feasible.
