摘要
不同密度、不同混交比例、不同造林方式的青杉混交林造林试验研究结果表明:在现有的混交试验林中,经营密度1 470株.hm-2取得较好的效果,青杉混交比以4∶6为最好。青钱柳在多树种混交的幼林中套种,23年生胸径达33.8 cm,树高26 m,青钱柳与多种针阔树种混交造林是成功的,四旁绿化也取得良好效果,说明青钱柳具有速生丰产等优良性状。
According to the result of afforestation experiment of the mixed plantations of Cyclocarya paliurus （ Batal. ） Ilinskaja and Chinese fir in different density, mixed ratio and cultivating mode, the management density of 1 470 tree ·hm^-2 performed well, and the proportion of C. paliurus and Chinese fir at 4：6 was optimal. In 23 years＇ plantation of C. paliurus mixed with several other tree, the diameter of C. paliurus reached 33.8 cm, and the height reached 26 m. The mode of C. paliurus mixed with several other varieties proved to be successful, and surrounding virescence also achieves excellent result.
