六、成果的应用和效益 (一)社会影响和效应 在我们开始进行5个树种的无性系育 种时,它们已不同程度地开始了种子园营 建工作。在70年代早期这样做是可以理解 的,适应当时人们的认识水平和国际状 况,从林木的生物学和遗传学特性出发, 不排除多途径的探索,因为各种方法都具 有其优点和局限性,它们甚至是互相补充 和互相渗透的。如我们现在提倡的优良家 系混繁无性苗造林,就是吸收了我国杉 木种子园20多年的研究成果。但我们的林 木育种工作必须随着理论水平的提高和国 际林木育种前进的步伐而前进,绝不能停 留在40年代理解的种子园水平,因为近10 多年,国际上的种子园内涵也有了重要改 变。
Application and Benefits of Achievements (I) Social Impacts and Effects When we started the clonal breeding of five tree species, they started the construction of the seed orchard in varying degrees. It is understandable to do so in the early 1970s. Adapting to the current level of people’s understanding and international status, many ways of exploration are not ruled out based on the biological and genetic characteristics of trees, because each method has its advantages and limitations They even complement each other and penetrate each other. As we now advocate the fine family mixed propagation asexual seedlings afforestation, is to absorb the Chinese fir seed orchard 20 years of research. However, our tree breeding work must advance with the improvement of the theoretical level and the progress of international forest breeding and must not stop at the level of the seed orchard understood in the 1940s, because the connotation of the international seed orchard has also undergone significant changes in the past 10 years .
