| 为探讨并了解火力楠混交造林的生长效果，通过开展火力楠与灰木莲和火力楠与湿加松混交种植试验，对三个树种混交林和纯林的树高和胸径进行调查，并计算3.5年时的材积与蓄积量，进行数据分析结果表明：混交造林1.5年生时，仅火力楠与湿加松混交时，火力楠胸径高于纯林的，其余均无差异；但3.5年生时，混交林中的灰木莲、湿加松的生长、材积和蓄积量显著高于各自纯林，而混交林中火力楠生长状况低于其纯林。由此可知，灰木莲、湿加松与火力楠混交能显著提高自身林分生长，火力楠作为伴生树种在今后的混交造林中具有较大推广价值。 |

| Abstract: |
| Through the mixed planting experiment of M. macclurei, trying to reveal the rationality of mixed forest. The tree height and DBH of three mixed forest and pure forest were investigated, and calculated the volume and stand volume of 3.5 years, and the results of data analysis showed that mixed forest afforestation 1.5 years old, only M. macclurei and hybrid pine mixed, M. macclurei diameter was higher than pure forest, the rest were no difference; However, at the age of 3.5, the growth, volume and stand volumeof the mixed M. conifera , hybrid pine was higher than that of the pure forest in the mixed forest, while the growth condition of M. macclurei was lower than that of the pure forest. It can be seen that the mixed flowers of M. conifera, hybrid pine and M. macclurei can significantly improve the growth of their own stands, and M. macclurei has a great popularization value in the future mixed afforestation |
