摘要:
以纳塔栎Quercus texana 1 年生容器苗为研究对象,采用析因试验设计,研究不同控释肥加载量和容器规格对纳塔栎苗高和地径生长的影响,并提出优化育苗方案。结果表明,容器规格对纳塔栎苗高和地径生长均产生极显著影响(P <0.01),容器越大,苗高生量越大,地径越粗;控释肥不同加载量对纳塔栎地径生长和高径比的影响不明显,但对苗高生长影响极显著(P <0.01),在控释肥3.5 kg·m-3 的加载量下,纳塔栎具有最大的高生长量和高径比;控释肥加载量和容器规格之间存在的交互作用对苗高生长和高径比产生了极显著影响(P<0.01),但对地径生长的影响不明显。综合不同容器规格和控释肥加载量的交互作用以及对育苗成本的考虑,结果发现,在使用18 cm × 20 cm 的容器和3.5 kg·m-3 控释肥加载量条件下,纳塔栎苗高生长最优,同时具有较好的地径生长。
Abstract:
In March 2016, 1-year container Quercus texana seedlings were selected for experiment on different controlled-release fertilizer andcontainer size in Tiantai, Zhejiang province. In November of the same year, determinations were carried out on height, basal diameter growth. Theresults showed that the size had significant positive effect on growth of height and basal diameter of seedlings (P<0.01). The effect of differentcontrolled-release fertilizer on basal diameter growth and height-diameter ratio of seedlings was not obvious, but significant on height, especially 3.5kg/m3 fertilizer had the largest height growth and height-diameter ratio. Multi-factors analysis of variance demonstrated that there was significantinteraction effect (P<0.01) between controlled-release fertilizer and container size on height growth and height-diameter ratio, whereas not significanton the basal diameter growth. Based on the interaction effect of the container size and fertilizer and consideration of seedling cost, we concludedthat container of 18 cm × 20 cm and with 3.5 kg/m3 controlled-release fertilizer was the best combination.
