摘　　要：利用福建省南平樟湖国有林场不同类型和规格的木荷苗木造林对比试验林,系统研究苗木类型与规格对造林成活率、保存率、幼林生长及叉干率的影响。结果表明:轻基质营养袋苗、大田裸根Ⅰ级苗和大田裸根Ⅱ级苗3种类型和规格的木荷苗木造林成效差异显著,其中采用轻基质营养袋苗造林可取得95.56%的造林保存率,且叉干率只有3.47%;造林后木荷1年生幼苗地径、树高和冠幅的平均值分别达到了1.63cm、107.10cm和56.43cm;造林后2年生,其地径、树高和冠幅的平均值分别达到了2.61cm、224.90cm和113.07cm,均优于大田裸根Ⅱ级苗和大田裸根Ⅰ级苗的造林成效,说明采用木荷轻基质营养袋苗造林可显著提高造林成活率和生长量,降低林木叉干率,全面提升造林成效。Effects of seedling types and specifications on survival rate,preservation rate,sapling growth and bifurca-tion rate were systematically studied by using the afforestation comparison experiments of Schimasuperba seedlings with different types and different specificationlocated in Zhanghu State-owned Forest Farm of Fujian province.Re-sult shows that the three types （nutrition bags with light matrices ,grade-Ⅰbrae-root seedlings,grade-Ⅱbare –root seedlings）of Schima superba seedlings were remarkable different.Among them,the seedling preservation rate of 95.56% and the stem forking rate of 3.47% were obtained by used light matrix nutrition bags of seedlings,which first years after planting,the average DBH,tree height and crown width is 1.63 cm,107.10 cm and 56.43 cm re-spectively;second years after planting,the average DBH,tree height and crown width is 2.61 cm,224.90 cm and 113.07 cm respectively.Tahey are all optimal than theⅠand Ⅱlevel bare root seedlings.with light matrix nutrition bags Schima superba seedlings planting can significantly enhance the survival rate of afforestation,decrease the rate of seedling fork stem,increase afforestation effect.
