樟树播种育苗技术研究

Study on the Sowing Seedling-raising Technology of Camphor

[目的]研究樟树的播种育苗技术。[方法]以樟树种子为材料,以苗高、地径、主根长、侧根数、苗木总产量、合格苗产量为指标,探讨不同播种方法、施肥种类对樟树苗木质量、产量的影响。[结果]播种方法造成樟树主根长、侧根数、苗木总产量和合格苗产量差异极显著,苗高和地径差异显著,施肥种类造成所有指标差异极显著。宽条播的合格苗产量最高,分别是条播和撒播的258.3%和105.0%。增施磷、钾肥的樟树苗高、地径、主根长和侧根数分别是常规施肥的123.3%、128.3%、132.4%和135.2%。[结论]樟树播种育苗应采用宽条播,增施磷、钾肥培育壮苗。

[Objective] The purpose was to study the sowing seedling-raising technology of camphor.[Method] With camphor seeds as tested materials,seedling height,ground diameter,main root length,lateral root number,total seedling output and the output of qualified seedling as indices,the influences of different sowing methods and fertilization kinds on the quality and output of camphor seedlings were discussed.[Result] The sowing methods caused extremely significant differences on main root length,lateral root number,total seedling output and the output of qualified seedlings and significant differences on seedling height and ground diameter of camphor.The fertilization kinds caused extremely significant difference on all the indices.The output of qualified seedling of wide drill seeding was highest and 258.3% of drill seeding and 105.0% of broadcast sowing resp.The seedling height,ground diameter,main root length and lateral root number of camphor in the fertilization increased P and K were 123.3%,128.3%,132.4% and 135.2% of that in conventional fertilization.[Conclusion] The wide drill seeding should be used and the P and K application should be increased to raise strong seedlings in the sowing seedling-raising of camphor.
