十多年来,丘陵栽杉发展的速度快,范围广,面积大,在南方用材林基地建设中占有重要地位。为使今后丘陵栽杉有一个奋斗目标,现根据丘陵地区杉木生长情况和国家对杉木商品材的要求,确定林分平均胸径16厘米,作为成材标准,产量按农林部提出20年每亩出材10立方米的指标。要达到上述目标,实现速生丰产,一方面必须改良杉木的种性,选育优良品种,选择适宜种源,以适应丘陵的环境;另一方面必须创造适于杉木生长的立地条件,充分利用杉木速生期早的特点,实行高标准整地,精心管理,力争在头五年或头十年为达到成材和产量指标打下基础。现将栽培措施上的主要经验和科研成果介绍如下:
Ten years, the development of the hilly terpineus fast, wide range, large area, in the southern timber forest base occupies an important position. In order to have a goal of fir plantation in the future, according to the growth condition of fir plantation in the hilly area and the requirements of the state for fir commodity timber, the average diameter at breast height of 16 cm is determined as the standard of timber production. According to the output of the Ministry of Agriculture and Forestry for 20 years per mu 10 cubic meters of indicators. To achieve the above-mentioned goals and achieve fast-growing and high-yielding, on the one hand, it is necessary to improve the species of Chinese fir, breed fine varieties and select suitable provenances to adapt to the hilly environment; on the other hand, it is necessary to create site conditions suitable for the growth of Chinese fir, Fast-growing period of early features, the implementation of high standards of site preparation, careful management, and strive to achieve the first five years or the first ten years to lay the foundation for production and output targets. Now the main experience of cultivation measures and research results are as follows:
