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 .
