摘要
运用MATLAB软件对 7个种源的美国黄松及油松苗期苗高、地径和根、茎、叶干物质积累量差异进行了比较分析 ,结果表明 :2年生油松的苗高生长量与各种源美国黄松的苗高生长量间存在显著或极显著差异 ,且油松的苗高生长量最大 ;美国黄松Ⅴ号 (BlackHill)种源苗木的地径生长量、叶、茎、根干重积累量与油松和其它种源美国黄松苗的各项指标间存在显著或极显著差异 ,且美国黄松Ⅴ号 (BlackHill)种源苗木的地径生长量及其叶、茎、根干重积累量均最大。综合各种源苗木的生长表现及其原产地的自然条件 ,提出了适于黄土高原不同气候区的引种地。
With Matlab software,differences among height,diameter on the ground,dry weight of roots,stems and leaves of Pinus tablaeformis and 7 sources of Pinus ponderosa have been analyzed respectively.The results showing an obvious or immense differences occur in two-year old seedling of Pinus tablaeformis and variows sources of Pinus ponderosa.Meanwhile,growth of seedling of Pinus tablaeformis are the highest.Other indexes(including diameter on the ground,dry weight of roots,stems and leaves)of V source(Black Hill)of Pinus ponderosa are the greatest.Combination growthof various souces of seedling with their original site conditions,the seed sources of seedling adapt to different climate zones on loess Plateau have been posed.
