【摘要】 采用切根及喷云大-120 对冲天柏苗木生长的效果进行了试验, 结果表明: 切根和喷云大- 120 处理对冲天柏苗木的生长作用一般不显著, 在苗高、地径、冠幅等10 个性状中, 仅喷云大- 120 对主根发育影响显著,对侧枝数的发育呈负作用, 故在冲天柏育苗中不宜采用切根和喷云大-120 作技术处理。更多还原

【Abstract】 The experiment of effects on the seedling growth of Cuoressus duclouxiana by treatments of cutting roots and spraying BR-120 was conducted. The results show that cutting roots and spraying BR-120 have no obvious effect to the growth of the seedlings. In the 10 detected characters, such as seedling height,ground diameter,canopy etc. spraying BR-120 improves the development of main roots greatly, but affects negatively to the development of lateral branches. So, it is unsuitable taking the ways of root cutting and BR-120 spraying in the cultivation of Cuoressus duclouxiana.更多还原
