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。
According to the principle of controlling three factors: location, heredity and density, the fast growing and high-yield Pinus massoniana forest was built. Five major technical measures were put forward, including afforestation land, good provenance, reasonable land preparation, proper planting and cultivation of container seedlings 3 ~ 4 years after afforestation in a timely and reasonable young tending. The results of the growth of young forest showed that the growth rate of 1 to 5 years exceeded 31.8% ~ 60.0% compared with the national professional standard of fast growing and high yield forest, and the growth of DBH exceeded the standard by 21.1 % ~ 24. 0%, 5-year volume growth exceeded the standard of 368.0%, reaching the goal of the fast-growing forest young forest.
