湿地松不同造林密度试验研究

Research on Test for Different Afforestation Density of Pinus elliottii Engelm

摘要:

笔者对湖北荆门彭场林场3种造林密度14 a生湿地松人工林树高、胸径、单株材积的生长量进行了调查分析。结果表明:不同造林密度对林木树高影响不大,对胸径和单株材积具有较大影响,不同密度间差异显著。

Abstract:

The authors made survey and analysis on 3 kinds of plant density of growth increment of tree height,D.B.H.,single tree volume for 14 year-old plantation of Pinus elliottii Engelm in Pengehang For- est Farm in Jingmen City of Hubei Province.The result indicated that different planting density didn't have relatively big influence to the tree height,but bigger influence on D.B.H.and single volume,it had signifi- cant differences among different density.
