摘要
对美国山核桃1年生实生苗采用切根、移栽两种断根方式,研究不同断根方式对美国山核桃实生苗生长的影响。结果表明:切根处理能促进苗木地上部分和地下部分快速生长,移栽处理能促进地下部分增粗生长,对地径生长无显著影响。移栽处理能显著促进苗木地下侧根增长、增粗,以及鲜质量增加,切根处理能显著促进苗木须根数量和鲜质量增加。对于提高苗木质量和促进美国山核桃产业发展提供参考。
The influences of different root-excision methods on the growth on ground and underground of Carya illinoensis was studied.The root-cutting,transplanting and CK were used as experimental treatments.The results showed：the root-cutting could promote fast growth of the ground and underground part,the transplanting could incease the diameter of underground part increasing,but couldn＇ t increase collar diameter significantly.The transplanting could increase the lateral root and fresh weight,the number and fresh weight of the fibrous roots were increased by root-cutting.
