研究了以粉碎后的树皮为主要基质成份和以锯屑为主要基质成份的两种轻型基质系列及两种不同容器材料,三种不同容器尺寸对马尾松容器苗生长的影响。用主成份分析法探讨了马尾松容器苗质量评价指标,并在苗木7个形态指标测定的基础上分析得出了较优的处理组合。基质以树皮系列,容器材料以无纺布,尺寸以中、小号容器为较佳。用回归组合设计方法设计了25个配方,得到了基质系列、容器材料,尺寸和配方的较优组合。
The effects of three light container series, two kinds of light substrate series with crushed bark as the main matrix component and sawdust as the main matrix component, and three different container sizes on the growth of Pinus massoniana container seedlings were studied. Principal component analysis method was used to evaluate the quality evaluation index of Pinus massoniana seedlings. Based on the determination of seven morphological indexes of seedlings, the optimal treatment combination was obtained. Matrix bark series, container materials to non-woven, size to medium and small containers are better. 25 formulas were designed by regression combination design method, and the optimal combination of matrix series, container materials, size and formula were obtained.
