摘要
为了筛选适宜1a生油松(Pinus tabulaeformis)苗生长的松树皮最佳粒径,通过测定不同单一粒径条件下油松的生长指标,运用方差分析、多重比较、多目标决策方法对油松苗的生长状况作出综合评价。研究结果表明:粒径为4~5mm的松树皮作为基质,培育的油松苗侧根数量最多,为13.1根,苗木品质指数最大,为0.090,顶芽干重最重,为11.37mg/株,综合评价分值最高。可见粒径为4~5mm的松树皮最适宜栽培1a生油松苗。
In order to find out the pine bark optimal size for 1a container seedling of P.tabulaeformis,By measuring P.tabulaeformis growth index under different particle size,and using variance analysis and multiple comparison,multi-objective decision making method to make a comprehensive evaluation for seedlings growth status.Results showed that under the condition of the particle size of 1-2mm pine bark,the P.tabulaeformis seedling lateral root number was up to 13.1 root,seedling quality was best of 0.090 and the value multi-objective decision method to comprehensively evaluate was highest of 1,bud dry weight was best of 11.37mg·tree-1,the evaluation scores was highest.So the size of 0.5~1mm pine bark was most suitable for 1a pine seedlings cultivation.
