人所共知,苗木质量关系到造林成败,而 县大碾子村进行造林成果调查时,在大杆木当优质苗木培育技术问题解决之后,能否真 沟头道小沟西坡发现一奇特的造林地段,该,N用优质苗木造林就决定于苗木质量管理 地段为 100cm X 60cm X 30cm大鱼鳞坑整了。目前一些地方（特别是个体育苗）苗木 地,树种为落叶松,每穴植苗2株,明显是质量呈下降趋势,直按影响工程林质量,这1次造林1次补植而成,第1次造林成活的一问题t。不引起高度重视并加以杆决,必将 幼树高达 2～3m,第 2次补植成活的幼树仅遭致严重损失。笔者试以落叶松育苗为例,对 高 0.3～0.7m,从高度和地径上判断,二者lq4林质量管理问题作一些粗浅分析,以 年龄至少相差2～3年,但仔细查数轮枝,竟供参考。
It is well known that the quality of seedlings is related to the success or failure of afforestation. However, when the investigation of afforestation achievements is carried out in Xiaodianzai Village, the peculiar Afforestation sites, the N afforestation with high-quality seedlings decided to seedling quality management lot for the 100cm X 60cm X 30cm large scale pit whole. At present, in some places (especially individual seedlings) seedlings, the larch tree species, seedling per hole 2, obviously the quality is declining trend, direct impact on the quality of engineering forest, this 1 afforestation replantation 1, 1 A problem of subsistence afforestation. Not to attach great importance to and to be resolved, the saplings will be as high as 2 ~ 3m, the second replanting survival saplings suffered only serious damage. The author try larch seedlings as an example, on the high 0.3 ~ 0.7m, judging from the height and diameter, both lq4 forest quality management problems for some superficial analysis, with a difference of at least 2 to 3 years, but carefully check the number of rounds Branches, actually for reference.
