【摘要】 通过三十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。三十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。

【Abstract】 Through the cultivation experiment of thirty clones in Nanyang,the author selected preliminarily seven excellent clones and promoted it into production.This measurement improved the efficiency of early selection of clone and provided the foundation to breeding the small-diameter lumber of fast-growing in their early stages.The cultivation experiment of thirty clones in Nanyang is an important part of the four synchronous forestation sites in China(Luoyang city in Henan,Nanyang city in Henan,Xiaolong mountains in Ganshu,Daxin district in Beijing).The breeding efficiency was improved through the afforestation test in the various areas of China using the same clones.The research has essential difference from the previous study to select clones.
