墨西哥柏育苗试验结果分析

Results Analysis on the Experiment of Cuoressus lusitamica Cultivation

切根及喷云大- 120 对墨西哥柏苗木生长的效果的试验结果表明: 切根和喷云大- 120 处理对墨西哥柏苗木生长的促进作用不大。在苗高、地径、冠幅等10 个性状中, 仅切根对茎叶鲜重呈明显负作用, 切根、喷云大- 120 及交互作用对根鲜重亦呈明显的负作用。在墨西哥柏育苗中不宜采用切根和喷云大-120 处理。

The experiment of effects on the seedling growth of Cuoressus lusitamica by treatments of cutting roots and spraying BR-120 was carried out. The results indicate that cutting roots and spraying BR-120 have little improvement to the growth of the seedlings. In the 10 detected characters, such as seedling height,ground diameter,canopy etc., cutting roots affect negatively on fresh weight growth of leaf and stem; cutting roots, spraying BR-120 and doing them alternatively also show obvious negative effect on fresh weight growth of roots. So, it is improper taking the ways of root cutting and BR-120 spraying in the cultivation of Cuoressus lusitamica.
