经多年试验,推出了林下毛竹造林技术。在针叶林中选择海拔高1 000m以下的山谷、坡麓、坑边、中下坡,坡度在5~25°,要求土层深厚、疏松、肥沃、湿润、排水良好的沙壤土、壤土。对原林分进行间伐,郁闭度控制在0.5~0.6,块状清理植被,块状整地栽植,采用规则或不规则林下造林。或小面积皆伐针叶树,全面整地,采用毛竹“集团”栽植。60~75块/hm2小面积整地,每“集团”栽毛竹5~6株。其余林地保持不变。该技术在不减少有林地面积的基础上维系着森林生态系统的稳定性,又促进毛竹生长。
After years of testing, launched under the forest bamboo reforestation technology. In the coniferous forest, the elevations of 1 000 m above sea level are selected in the valleys, pieds, pit sides and mid-down slopes. The slope is between 5 and 25 °. Requiring deep, loose, fertile, moist and well-drained sandy loam and loam. The original stand thinning, canopy density control in the 0.5 ~ 0.6, block clean-up vegetation, block preparation of land preparation, using regular or irregular afforestation. Or small-scale conifers, a full range of land preparation, the use of bamboo “group” planting. 60 ~ 75 / hm2 small area preparation, each “group” planted bamboo 5 to 6 strains. The remaining woodlands remain unchanged. The technology maintains the stability of forest ecosystems and promotes the growth of bamboo, without reducing the area of forestland.
