摘要
根系修剪能有效地调节根的发生与组成。疏根可使根系得到全方位更新 ,短截则使新根发生部位集中 ,易成竞争。轻剪利于夏季发根 ,重剪利于秋季发根。根系修剪在减少植株生长量的同时 ,促进了短枝发育 ,提高了植株C/N比 。
Root system pruning regulates the development and composition of root effectivelyThinning makes regeneration of all position of the root system,and heading makes new roots develop concentrately and become competitively easilyLight pruning promotes new roots in summer ,and so does heavy pruning in autumnRoot system pruning decreases the total growth with promoting the development of spurs and increasing the C/N ratio at the same time enormously
