华山松是我国特有的重要用材树种,分布范围广,并且形成了若干类型。为了解不同产地华山松种源的适应性、抗性、速生丰产能力、生态遗传的变异幅度和类型等,我们与贵州农学院林学系协作进行了华山松种源苗期试验。现将试验作如下小结:一、自然概况:育苗试验在我场三岔分场黄石崖苗圃进行,地处东经117°14′,北纬36°10′,海拔700m,属林内山谷梯田地,沙壤土,PH6.5,1979年全年降水978mm,
Huashan pine is an important timber species unique to our country, with a wide distribution and several types. In order to understand the adaptability, resistance, fast-growing and high-yielding ability, the extent and types of ecotype genetic variation in Huashan pine provenance from different areas, we conducted the seedling stage of Huashan pine provenance in collaboration with Forestry Department of Guizhou Agricultural College. Now the experiment is summarized as follows: First, the natural profile: nursery trials in my field three points Yat Huangshiya nursery, located 117 ° 14 ’east longitude 36 ° 10’ latitude 700m above sea level, , PH6.5, the year 1979, 978mm,
