摘　　要：为了提高黄羊滩沙地的造林成效,加快京津冀生态圈建设步伐,研究以樟子松和油松容器大苗为试验材料进行大苗造林,探讨了其造林季节、造林地形和首水方式等关键技术对其成活率的影响,研究结果表明:(1)不同造林季节对2树种成活率影响显著,表现为雨季造林显著高于春季和秋季造林,而春季和秋季造林差异不显著。(2)不同造林地形对2树种成活率影响显著,表现为平缓沙地造林优于坡形沙地。(3)不同首水方式对油松成活率影响显著,表现出半埋浇灌显著高于全埋浇灌;虽然其对樟子松成活率影响不显著,但依然表现出半埋浇灌高于全埋浇灌的趋势。(4)在相同处理下,樟子松大苗造林成活率均略高于油松。综上所述,对于樟子松和油松大苗造林,宜在雨季,选择平缓沙地,并采用半埋浇灌的首水方式。In this study,in order to improve afforestation effect in Huangyangtan sandy land,speed up the construction of Beijing-Tianjin-Hebei ecological circle,Pinus sylvestris var.mongolica Litv.andPinus tabuliformis Carrièrewere used as test materials for large-seedling afforestation,and the effects of key techniques such as afforestation season,afforestation terrain and initial irrigation method on survival rate were discussed.The results showed that:(1)Different afforestation seasons had significant influence on survival rate of two tree species,which was manifested as that afforestation in rainy season be significantly higher than that in spring and autumn,while the difference between afforestation in spring and autumn be not significant.(2)Different afforestation terrain had significant influence on survival rate of two tree species,which was manifested as that afforestation in flat sandy land be better than slope sandy land.(3)Different initial irrigation methods had significant influence on survival rate ofPinus tabuliformis Carrière,which was manifested as that semi-buried irrigation be significantly higher than full-buried irrigation;Although it had no significant influence on the survival rate ofPinus sylvestris var.mongolica Litv.,it still showed a trend of semi-buried irrigation higher than full-buried irrigation.(4)Under the same treatment,the survival rate ofPinus sylvestris var.mongolica Litv.with large seedlings were slightly higher than those ofPinus tabuliformisCarrière.In summary,for the afforestation with large seedlings ofPinus sylvestris var.mongolicaandPinus tabulaeformis,it was advisable to choose gentle sand land and adopt the initial irrigation method of semi-buried irrigation in rainy season.
