摘　　要：为了解决新建核桃园成活率低、长势不整齐的问题,对新栽幼树进行了不同程度的剪截,并对成活率及生长情况进行调查。结果表明:剪截1/2、2/3与极度重剪成活率无差别,均为100%。在一定范围内随着剪截量的加大新栽幼树成活率逐渐提高,萌芽期逐渐推迟,新梢的生长势由弱变强,枝条生长量由短变长,萌芽率逐渐降低,成枝率逐渐提高,干周粗度、枝条总生长量逐渐增大。Investigation on survival rate and growth condition of young walnut tree that used different cutting amount.The results showd that the survival rate gradually increased in a certain range with the amount of cut increased.The Germination Stage was gradually postponed.The growth vigour of new shoot was from weak to strong.The growth increment of branch was from short to long.The rate of germination gradually decrease and tire Branching rate was Gradually improve.The circle of trunk,growth increment of branch was gradually increasing.
