摘要
对7年生富士苹果树的根质量密度和根长密度分布进行了研究。结果表明:根系随深度和距树干距离的增大而减少,d>2mm的根(输导根)占质量比重大,而d<2mm的根(吸收根)占根长比重大。
In the experiment, the root length and weight contribution were studied. Root was divided into two samples, the d>2 mm root constitute the ma jority of weight while the d<2 mm root constitute the ma jority of length. Root concentration decreased with the increase of soil depth and distance from the tree.
