马尾松速生丰产林营建技术的研究

Study on Establishment Technique for Fast - Growing and Nigh-Yield Pinus Massonlana Forest

根据立地、遗传、密度3大因素控制的原则，营建马尾松速生丰产林，着重采取了选用良好的造林地、优良种源、合理整地、适当密植与培育容器苗造林5项主要技术措施，并在造林后3～4年内进行及时合理的幼林抚育。从幼龄林生长量测试结果表明：与国家速生丰产林专业标准相比较，1～5年生高生长量超标达31．8％～60．0％4～5年生胸径生长量超标达21．1％～24．0％，5年生材积生长量超标达368．0％，达到了预期的速丰林幼林期的培养目标。

Based on 3 major control factors of site, genetics and density, 5 technique methods were adopted when established high-Yield and fast-growing Pinus massoniuna forest such as good site, good provenance, rational ground making and dense plantation, cultivation of container seedling. Young forest was tendered in time 3-4 years after afforestation. The result of young forest growth determination showed height growth of 1-5 year forest exceeded by 31. 8%-60%, D. B. H. growth of 4-5 year forest exceeded by 21. 1%-24.0%, volume growth of 5 - year forest by 368. 0% compared with the national high - yeld and fAnt - growing forest stardard.
