我省川西高山林区人工更新工作,通过反复的生产实践和科学试验,总结出了冷杉、云杉“宽带、大穴、丛植”的更新技术,提高了人工更新的保存率,受到许多营林单位普遍重视.但丛植更新尚存在着林分密度大,丛内株距短,林木间竞争剧烈,如抚育间伐不及时,则会影响林木的生长.因此,在研究冷杉、云杉生长特性和自然分布规律的基础上,川南森工局于1965年开始,进行群团状造林的试验.

Through repeated production practices and scientific experiments, the authors updated the technologies of fir, spruce “broadband, big hole, clump planting” and improved the preservation rate of artificial regeneration, which was affected by many silviculture Units generally focus on.But Cong Cong update there are still stand density, short within the plexus, intense competition among trees, such as tending is not enough time, it will affect the growth of trees.Therefore, in the study of fir, spruce growth characteristics and On the basis of the natural distribution law, Chuannan Forestry Bureau began its experiment in 1965 with group afforestation.
