杨树是我省主要的速生造林树种之一,它具有分布广、适应性强、繁殖容易、成活率高、轮伐期短、在短期可以获得大量的木材等特点。因此,加速繁育杨树良种,努力实现杨树良种化,大力发展杨树造林,对落实毛主席关于“绿化祖国”、“实行大地园林化”的伟大指示,迅速改变自然面貌,促进农牧业稳产高产,扭转缺材少林的被动局面,争取在短期内实现地方木材自给,具有重要意义。我省从1959年就开始着手建立杨树新品种与繁育示范基点。初步统计,通过引、选、育种,现已有杨树原始材料500多号,进行生产试验的有50余种。
Poplar is one of the main fast-growing afforestation species in our province. It has the characteristics of wide distribution, strong adaptability, easy breeding, high survival rate, short rotation period and availability of large amount of wood in short term. Therefore, to speed up the breeding of poplar varieties, strive to popularize poplar trees, vigorously develop poplar afforestation, implement Chairman Mao’s great instructions on “greening the motherland,” and “implementing the earth garden”, to rapidly change the natural landscape and promote agriculture and animal husbandry It is of great significance to stabilize the high yield and to reverse the passive situation of the lack of material in Shaolin and strive to achieve local timber self-sufficiency in a short period of time. From 1959 in our province began to establish a demonstration base of poplar new varieties and breeding. Preliminary statistics, through the introduction, selection, breeding, poplar now available more than 500 raw materials, the production of more than 50 kinds of tests.
