残次烟叶型生物有机肥在烤烟生产上的应用

以烤烟生产、收购过程中产生的残次烟叶为主料,添加不同配比的菜籽饼、蚯蚓粪、生物炭、鸡粪等进行高温发酵,堆制残次烟叶型有机肥,并应用于大田烟叶生产。结果表明:以"35%残次烟叶+30%蚯蚓粪+30%生物炭+5%菜籽饼"配比制成的残次烟叶型有机肥对烟株株高、茎围、有效叶片数等农艺性状有较好的促进作用,同烟草专用基肥处理相比差异不明显,可代替烟草专用基肥在烟草上应用。

Application Effects of Bio-organic Fertilizer Resulted from Defective Tobacco Leaves on Fluecured Tobacco Production

Defective tobacco leaves, came from production and tradition of Leiyang planting region, was smashed and composted with a serious of materials included rapeseed residue, wormcast, biochar, chicken manure and microbial agents by high temperature fermentation composting system in Leiyang company, and then, turned to superior bio-organic fertilizer, which was applied into tobacco planting. The results showed that, T2 composted bio-organic fertilizer, consisted of 35% defective leaf, 30% wormcast, 30% biochar and 5% rapeseed residue, had positive effects on tobacco growth (plant height, stem diameter, effective leaves, etc.) compared with commercial tobacco substrate, which can be applied in tobacco planting instead of commercial tobacco substrate.
