| 摘 要： | 在大兴安岭林区的干旱阳坡火烧迹地进行了整地方式、苗木T/R比、造林季节和保苗剂应用对造林成活率影响的研究。结果表明:鱼鳞坑整地能够降低土壤温度,增加土壤含水率,进而提高樟子松苗木造林成活率;随着苗木T/R比的降低,樟子松苗木造林成活率增加;樟子松和落叶松苗木春季造林成活率均高于秋季;使用HRC保苗剂后樟子松和落叶松苗木造林成活率平均增加13.7个百分点。 |

| Abstract: | Effects of site preparation methods,top/root biomass ratio of seedlings,season of afforestation and HRC seedling protectant on survival rate of afforestation were investigated in burned area of dry south-slope in Daxing'anling forestry land.Result shows that site preparation of fish scale pits can decrease soil temperature and increase soil water content,then increase survival rate of Pinus sylvestris var.mongolica.With the decrease of top/root biomass ratio of seedling,the survival rate of Pinus sylvestris var.mongolica enhanced.The survival rate of Pinus sylvestris var.mongolica and Larix gmelinii in spring were higher than that in autumn.After applying HRC seedling protectant,the survival rate of Pinus sylvestris var.mongolica and Larix gmelinii increase by 13.7%. |
