截至“十二五”末,全区审(认)定通过的林木良种66个,其中优良种源12个、一代种子园3个、母树林3个、优良无性系11个、优良品种37个。审(认)定通过的生态造林树种良种涵盖了我区南部山区、中部沙区、北部平原地区造林绿化的主要树种;经济林良种已成为我区林业产业发展的支柱品种;园林绿化良种在我区城市园林绿化中被广泛应用。目前全区林木良种产业发展还存在结构性矛盾突出、良种推广率低等问题,笔者通过踏查统计、分析研究提出了做好林木良种产业产学研相结合,进行区域试验,有序开展引种驯化,制定标准技术规程,提高全区主要造林树种林木良种使用率的方法和对策。
Up to the end of the “Twelfth Five-Year Plan” period, there were 66 improved tree species approved (confirmed) by the district, including 12 good provenances, 3 first-generation seed orchards, 3 parent trees, 11 fine clones, fine varieties 37. The fine varieties of ecological afforestation species approved by the trial (recognition) covered the main tree species of afforestation in the mountainous areas in the southern part of our region, the sandy area in the middle part and the plains in the northern part of China. The fine varieties of economic forest have become the mainstay species for the development of forestry industry in our region. Urban landscaping has been widely used. At present, there are still some structural contradictions in the development of forest seed industry in the whole region, such as the prominent structural contradictions and the low promotion rate of seed breeding. The author puts forward the following suggestions: a combination of production, study and research of forest seed improvement industry, regional trials, and introduction and domestication , The development of standard technical regulations, improve the main afforestation species of forest seed usage and countermeasures.
