摘要：以4个柚木(TectonagrandisL.f.)无性系为研究材料,采用裂区设计,无性系为主区,6个施肥处理为副区,研究不同柚木无性系对施用不同肥料配施微量元素的响应。结果表明:3年生无性系间的树高、胸径和单株材积生长差异显著或极显著,7514无性系表现最好,分别是表现最差的7114无性系的1.25、1.32和2.03倍;3年生施肥处理间树高和单株材积差异显著或极显著,以处理1生长最好,但无性系间的生长效应大于施肥处理间增产效应,无性系选择尤为重要。3年生树高、胸径和单株材积无性系与施肥处理交互作用显著或极显著,不同无性系对不同肥料施用和添加微量元素反应不一,生长表现好的无性系对施肥处理的反应不敏感,而表现差的无性系对肥料反应敏感。柚木无性系造林应根据不同无性系采用不同施肥处理,以充分发挥它们的生长潜力。
Four teak(Tectona grandis L.f)clones were used as materials to study the response of different teak clones to combined application of different fertilizer and trace elements by using split plot design,clone as the main area,and six fertilization treatments as the secondary area,so as to provide scientific basis for economic fertilization,precision fertilizationand application of trace elements in teak clone afforestation.There were significant or extremely significant differences in the growths of tree height,DBH and individual volume at age of three among clones,and No.7514 clone performed the best,which were 1.25,1.32 and 2.03 times as much as that of the worst No.7114 clone,respectively.There were also significant or extremely significant differences in the growths of tree height and individual volume in 3-year-old among fertilizer treatments.Fertilizer treatment 1 had the best growth,but the growth effect between clones was greater than that between fertilization treatments.Clone selection was particularly important.The interactions between clones and fertilization treatment on tree height,DBH and individual volume in 3-year-old were significant or extremely significant.Different clones had different responses to different fertilizer and trace elements application.The clones with good growth performance were not sensitive to fertilization treatment,while the clones with poor growth performance were sensitive to fertilizer treatment.In order to give full play to the growth potential of teak clones,different fertilization treatments should be adopted according to different clones.
