【摘要】 通过30个无性系在南阳区域的栽培试验,初选7个早期表现优良的无性系.推广到生产中去。提高无性系早期选择的效率,为楸树早期速生小径材培育提供了依据。30个无性系在南阳区域的栽培试验是全国四个同步造林试验点的重要组成部分(河南洛阳、河南南阳、甘肃小陇山、北京大兴)。通过相同的无性系,全国分别区域的造林试验,提高了选育效率。本实验研究和以往一地选出无性系,再做立地类型试验有本质的不同。更多还原

【Abstract】 Thirty hybrid clones cultivation experiment in the Nanyang region, the early primaries excellent performance 7 hybrid clones. Extended to the production to go. Improve the efficiency of early selection of clones for the early fast path Catalpa trees provide a basis for training materials. Thirty hybrid clones in Nanyang region is the cultivation of the four pilot sites simultaneously afforestation important component (Luoyang Henan, Nanyang Henan, Xiaolongshan Gansu, Daxing Beijing ). By the same clones, respectively, the National afforestation areas to improve the efficiency of breeding. The experimental study and the previous one to select clones, then a site is fundamentally different types of tests.更多还原
