【摘要】 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。更多还原

【Abstract】 Studies have been made of the effect of ground bark and sawdust used for main light medium, two kinds of pocket material and three kinds of pocket sizes, on the growth of container nursery for Pinus massoniana. The method of principal component analysis has been used in appraising quality indices of container nursery. And on the basis of seven quality indices, the advanced treatment combinations have been obtained. Ground bark, abhesive-bonded fabric, and middle and small pocket sizes have been proved to be advisable as opposed to sawdust, plastic film and large pocket size. Twenty five mixed mediums were designed by means of regression combination design, from which advanced combination of medium, pocket material and pocke sizes have been selected.更多还原
