摘　　要：以蔗渣、木屑为原料与不同物料配比进行堆沤制成基质,开展西南桦幼苗的基质试验。结果表明:所有基质的理化性质均优于森林土(CK);不同基质对西南桦幼苗地径、苗高、地上部分干重及地下部分干重的影响都存在极显著差异,其中2号处理基质的表现最好,与森林土(CK)相比,苗高高出134%,地径高出71%,地上部分干重高出235%,地下部分干重高出164%。可在西南桦幼苗培育中加以推广。Using bagasse and sawdust as raw materials, and combined with different ratio materials, the matrix has been made, and a test of seedling growth of Betula alnoides also been carried out. The results showed that： The physicoehemical properties of all matrixs were better than the forest soil （CK）. The difference of different substrates on the ground diameter, height, aboveground dry weight and under- ground dry weight was extremely significant, and the No. 2 matrix performed best. The seedling height, ground diameter, aboveground dry weight and underground dry weight were 134% , 71% , 235% , 164% higher than control respectively. So, this matrix can be popularized in practice on the seedling cultivation of Bitola anodies .
