对大兴安岭西林吉地区的樟子松野生苗进行了裸根不带土移植造林的试验.结果表明,只要掌握好起苗季节、起苗后尽快栽植,并保存一定的根量,即可保证移植造林成功.成活率达97%～100%,造林效果优于经冬藏的樟子松培育苗和兴安落叶松培育苗,且幼林生长势一直表现良好.用萘乙酸、吲哚乙酸、高效生根剂和ABT生根粉等8种药物进行根系处理,对造林成活率的影响不大,而对造林当年高生长率、地径生长率产生明显影响.这种影响在造林1～2年后逐步消失.建议该地区造林中充分利用这一天然资源,加快迹地更新速度.
The experiment of bare root without afforestation on the wild seedlings of Sylvestris var. Mongolica in Xilingi area of Daxinganling Mountains was carried out. The results showed that as long as the seedling raising season was seized, planting as soon as possible after seeding, and saving a certain amount of roots, The success rate of afforestation was 97% -100%, afforestation effect was better than that of Pinus sylvestris var. Mongolica and Larix gmelinii seedlings grown in Dongzang and the growth potential of young forest had been good. With naphthalene acetic acid, indole acetic acid, Agent and ABT rooting powder for root treatment had little effect on afforestation survival rate but had a significant impact on the high growth rate and diameter growth rate in the year of afforestation.The effect gradually disappeared after 1 to 2 years of afforestation We suggest that this area should make full use of this natural resource in afforestation to speed up the pace of land exchange.
