摘要
研究了石灰岩土壤肥力因子与淡竹生长因子之间的相关性。研究指出：石灰岩土壤肥力因子对淡竹生长的影响显著，它们之间的回归关系和复相关系数均达极显著水平。土壤肥力因子对淡竹不同生长因子的影响程度不同，不同肥力因子对淡竹生长的作用大小也不相同。每个淡竹生长因子都有影响其生长的主要肥力因子。
Tbe correlation between the growth of Phyllostachys glauca McCl. and the fertility fac-tors of soil in the limestone area is studied. The results indicate that:(1)The effect of fertilityfactors of limestone soil on the growth of Phyllosstachys glauca McCl.is significant,and theregressive and heterogeneous coefficients are very remarkable. (a= 0.01).(2)The degrees ofthe effects of fertility factors on the growth of Phyllostachys glauca McCl.are various. (3)There are 3～4 chief fertility factors of limestone soil to each growing factors of Phyllostachysglauca McCl.
