新疆国营农场栽有防护林和四旁绿化植树五十多万亩。这样大的造林面积在树种选择上,大多选用了速生、短寿、喜水、病虫害严重的箭杆杨,耐旱、长寿的乡土榆类用的反少,而对于常绿针叶树的选用几乎等于零。因此,当秋季树叶凋落后,农场在漫长的冬季,场舍、田野见不到绿色,一片萧瑟单调。如何迅速引种栽培适应性强、观赏性好、经济价值大,既能供用材,也是防风固沙的优良常绿针叶树种,绿化农场并加强冬春的防风效果,这是急待解决的一个问题。 近年来,我们进行了樟子松大苗小苗引种栽培试验,获得了良好效果。并通过各地造林实践调查,初步认为樟子松在我区是有发展前途的优良用材、防护、绿化树种。在
Xinjiang’s state-owned farms planted shelterbelts and surrounded by more than 500,000 mu of green trees. Such a large afforestation area in the choice of tree species, most of them use the fast growing, short life, hi water, serious diseases and insect stems Yang, drought, longevity of native elm anti-less, and the selection of evergreen conifers is almost equal to zero . Therefore, when the fall of the leaves in autumn, the farm in the long winter, venues, fields can not see the green, a bleak monotonous. How to quickly introduce and cultivate cultivation adaptability, good ornamental, economic value, both for timber, but also the excellent evergreen conifers of windbreak and sand fixation, greening farms and to strengthen the windproof effect of winter and spring, which is an urgent problem to be solved. In recent years, we conducted seedling introduction and cultivation of Pinus sylvestris seedlings and achieved good results. And through the practice of afforestation around the investigation, initially think Pinus sylvestris in our area is a promising material, protection, afforestation species. in
