摘　　要：为研究氮、磷和钾不同比例混合配制对思茅松幼林生长的影响,以3 a生思茅松为研究对象,采用“3414”不完全区组设计开展追肥对比试验。结果显示,施肥能显著促进思茅松幼林生长,在所配制的13种肥料配方中,以T6处理(氮、磷和钾分别为每株300、600和150 g的配方)对思茅松幼林的生长促进作用最大,追肥1.5 a后幼林的平均树高、胸径和单株材积分别较对照增长53.5%、80.7%、340.0%。300 g氮肥+600 g磷肥+150 g钾肥配方在树高、胸径、单株材积3个指标上均与其他12个配方存在显著或极显著差异(P<0.05或P<0.01)。研究结果表明:施用肥料能获得较高的木材增产效益。In order to study the effects of different fertilizer mixture on young-age Pinus kesiya var.langbianensis forest,with 3-year-old P.kesiya var.langbianensis as the research object,the 3414 incomplete block orthogonal design was employed to fertilization.The results showed that the fertilization treatment by nitrogen fertilizer of 300g+phosphorus fertilizer of 600 g+potassium fertilizer of 150 g was most efficient for trees growing in the 13 treatment,the average height,DBH and individual volume increased by 53.5%,80.7%and 340.0%respectively compared with CK at 1.5 years after fertilization.After1.5 years fertilization,the average height,DBH and individual volume of the trees stand applying nitrogen fertilizer of 300 g+phosphorus fertilizer of 600 g+potassium fertilizer of 150 g were extremely significantly difference or significantly difference from other 12 fertilizer formulas,and fertilizer could increase the yield and wood benefit of per unit area.
