林木产地试验是指在一个树种的自然分布范围内,把各生态区的种子或苗木集中在一点或多点进行造林试验,以探明该树种在不同产地的遗传变异特点和增产效益,从而为确定最适种源划定种子调拨区,为合理组织种子供应、种子园和母树林基地建设提供根据。林木产地试验是重要的育种措施之一,已有悠久的历史。法国的德·蒙素从1821年就进行了欧洲赤松产地试验。以后,对欧洲赤松、欧洲云杉等曾组织过
Forest production test refers to the natural distribution of a tree species, the ecological zones of the seed or seedling focus on one or more afforestation experiments to prove that the species in different areas of genetic variation characteristics and yield benefits, so as Determine the most suitable source to delineate the seed allocation area, to provide a reasonable basis for the organization of seed supply, seed orchard and parent tree forest base. Forest origin test is one of the important breeding measures and has a long history. De Monsieu French from France in 1821 conducted a trial of Pinus elliottii. Later, the European pine, European spruce had organized
