烤烟漂浮育苗基质不同配方筛选及效果比较

Formula Selection and Effects Comparison on Media for Tobacco Float System

以现行烤烟育苗基质为对照,按不同比例山砂、酒糟有机肥、糠壳和锯末组合而成的育苗基质进行了对比试验。结果表明:处理T3(糠壳50%∶酒糟有机肥50%)和处理T6(基质50%∶细砂50%)在出苗和烟苗的农艺性状、大田生长等指标与对照差异不明显,成本低于对照,原料容易获得,不破坏生态。结果说明采用山砂、糠壳和酒糟有机肥作为育苗基质,有一定的推广价值和应用前景。

Growing media for tobacco float system with different portion of sands,sake lees organic fertilizer,rice bran and sawdust were compared. The results indicated that difference among treatment T3（ rice bran50% ：sake lees organic fertilizer 50%）,T6（ medium 50% ：fine sand 50%） and the control were insignificant in seedling emergence and agronomic traits of tobacco seedlings,as well as field growth index. Costs of these two treatments were lower than the control. The raw materials were convenient to obtain and ecological friendly. The results showed that using sand,rice bran and sake lees organic fertilizer as medium was valuable for application.
