摘　　要：为探讨杉木、马尾松、木荷3种主要造林树种施用基肥的效果,于2017—2018年在福建省尤溪国有林场开展施用过磷酸钙、复合肥(K 2SO 4型)为基肥与不施基肥(CK)造林对比试验,分析不同基肥对杉木、马尾松、木荷裸根苗的造林成活率和当年树高的影响。结果表明:从成活率上看,过磷酸钙不影响杉木、马尾松、木荷造林成活率;含硫复合肥会对杉木、木荷裸根苗产生肥害,降低杉木、木荷造林成活率,而对马尾松裸根苗的造林成活率没有影响。从树高生长来看,过磷酸钙能明显促进杉木、马尾松、木荷的幼树生长;含硫复合肥对杉木、马尾松生长有促进作用,而未显著提高木荷生长。综合结果,杉木、木荷基肥适合用过磷酸钙,马尾松的基肥可以选用过磷酸钙或复合肥。To investigate the effect of base fertilizer application on three main afforestation tree species:Cunninghamia lanceolata,Pinus massoniana and Schima superba,a comparative experiment between application with superphosphate and complex fertilizer(K 2SO 4)and non-application of base fertilizers was conducted to analysis the different effects on survival rate and tree height of Cunninghamia lanceolata,Pinus massoniana and Schima superba′s root and seedling in Youxi nation forest farm of Fujian Province form 2017 to 2018.From the perspective of survival rate,superphosphate has no impact on the survival rate of Cunninghamia lanceolata,Pinus massoniana and Schima superba;sulfur-containing complex base fertilizer will cause fertilizer damage on Cunninghamia lanceolata and Schima superba′s root and seedling and reduce the afforestation survival rate of Cunninghamia lanceolata and Schima superba,while it almost has no impact on Pinus massoniana′s afforestation survival rate.From the perspective of stimulating tree height growing,superphosphate can significantly promote the growing of Cunninghamia lanceolata,Pinus massoniana and Schima superba′s seedling.Sulfur-containing complex fertilizer has a positive effect on growing of Cunninghamia lanceolata and Pinus massoniana,while little on Schima superba.In consideration of the effects of different base fertilizers on survival rate and growing of three kinds of main afforestation tree species,base fertilizers for Cunninghamia lanceolata and Schima superba is suitable for superphosphate,while base fertilizers for Pinus massoniana could be applied with superphosphate or complex fertilizers.
