摘　　要：以粉碎腐熟的花生糠为原料,进行了烤烟漂浮育苗基质的配制技术应用试验。结果表明:在腐熟花生糠、膨化珍珠岩、蛭石的不同配比中以70%腐熟花生糠+15%膨化珍珠岩+15%蛭石、80%腐熟花生糠+10%膨化珍珠岩+10%蛭石(体积比)配制的烤烟漂浮育苗基质上烟草种子出苗率均在90%以上,与原商品基质无显著差异,烟苗十字期后长势强,成苗快,且能较好抵御烟草炭疽病。其中,70%腐熟花生糠+15%膨化珍珠岩+15%蛭石配制出的基质效果最优。因此,利用粉碎腐熟花生壳来替代漂浮育苗基质中的草炭是可行的,且基质成本较低。Crumbled and decayed peanut shell was applied in the matrix of tobacco float seedling system, the test results showed that among various mixing proportions, the germination rates of tobacco seed in the matrixes of 70% decayed peanut shell ＋ 15% expanded perlite ＋ 15% vermiculite and 80% decayed peanut shell ＋ 10% expanded perlite ＋ 10% vermiculite （v/v） were over 90%, presented no significant difference comparing with commercial matrix; and tobacco seedlings in the mentioned matrixes grew vigorously and rapidly after cross stage and showed better resistance to anthrax, especially in the matrix composed of 70% decayed peanut shell. Therefore, it is feasible to use decayed peanut shell as a substitute for grass char in tobacco float seedling matrix and matrix cost could be reduced.
