白皮松容器育苗基质选择试验

Experiment on Media Selection for Seelling Raising ofPinus bungeana with Plastic Film Container

采用６种基质培育一年生白皮松容器苗，对不同基质引起的出苗率、苗木高度、主根长、侧根数、最长侧根差异作了调查分析，指出５号基质（５５％森林土＋３０％生黄土＋５％蛭石＋１０％沙土）培育白皮松容器苗效果较好，其次为１００％森林土。

Six media were adopted to raise yearling container seedling of Pinus bungeana. Thedifferences among media in germination rate, seedling height, taproot length, number of lateralroot and the longest lateral root were investigated and analysed. No. 5 (55% forest soil+30%new yellow soil + 5% montmorllonite+ 10% sand ) was the best media for culturing containerseedling of Pinus bungeana, while 100% forest soil was the second one.
