摘要
用切根及喷云大-120 对新银合欢作促进苗木生长的试验, 结果表明: 切根及喷云大-120 对新银合欢苗木生长的促进作用不大, 仅在苗木侧枝的形成上有一定促进作用, 且不利于苗木根系的生长发育; 故在新银合欢育苗中不宜采用切根及喷云大-120 的技术措施。
The experiment of effects on the seedling growth of Leacaena leucacephala by treatments of cutting roots and spraying BR-120 was carried out.The results indicate that cutting roots and spraying BR-120 have on obvious effect to the growth of the seedlings.The treatments can improve the formation of lateral branches in some degrees, but they are unfavorable to the growth of root system.So,it is improper taking root cutting and BR-120 spraying in the cultivation of Leacaena leucacephala.
