无性系林业是以近代遗传育种学理论为指导,在选种的基础上利用最能符合经营目标的一些植株做原株,通过科学方法大量增殖,生产无性系造林苗木,科学地在林地配置这些无性系,达到集约经营的目的。进行杉木无性系造林,将给营林技术带来一系列的变革和进步,带来巨大的经济效益。自1984年起,我场参加了由中南林学院主持的《杉类无性系选育》国家科技攻关项目,开展了杉木早期速生无性系选育研究工作,现将近6年的研究成果汇报如下: 自然概况金洞林场地处东经110°53′43″—112°
Clone forestry is based on the theory of modern genetic breeding as a guide, based on the selection of the use of the most in line with business objectives of some of the plants do the original plant, a large number of scientific methods of proliferation, the production of clonal afforestation seedlings, scientifically configure these in the woodland Clones, to achieve the purpose of intensive management. Cunninghamia lanceolata afforestation, silviculture technology will bring a series of changes and progress, bringing enormous economic benefits. Since 1984, my field participated in the national scientific and technological project of “Sugarcane clonal breeding” moderated by Central South Forestry College and carried out the research work on the early clonality selection of Chinese fir. Now, the research results of the past six years are as follows: Natural Overview Golden hole forest site is longitude 110 ° 53’43 "-112 °
