摘要
以１０种培养基质，对马尾松和杉木两树种进行容器育苗研究。结果表明：以竹叶为基本材料配制基质，比纯黄心土基质培育的马尾松和杉木百日苗，干物质重分别增加９３．２％和５３．９％；与蛭石配制的基质相比，分别增加４３．９％和１０４．０％；与松树皮配制的基质相比，分别增加２５．０％和４２．９％。以松针为基本材料配制的基质效果近似于竹叶。两者对苗木生长的影响，与各处理相比较，均达到了极显著水平。通过培养基质理化性质与苗木生物量相关的矩阵分析，容器基质的容重和孔隙度对苗木生长影响最大；基质内有效养分含量，特别是磷含量的多少很重要。两树种对各种理化因子反映基本一致，但对具体营养元素的要求有所不同。马尾松要求含磷量较高，杉木对氮水平敏感。竹叶和松针配制的基质，表现了良好的理化性质，促进了两种苗木早期菌根化和快速生长。
Study on Mediums was conducted for two species, Masson pine and Chinese fir,in the past two years.There were 10 different formulations for the test.The dry weight of the 100 day seedling of Masson pine in the pot with Bamboo leaves as the medium is 93.2%,43.9%,25.0% over those growing in the yellow soil,the vermiculite,the rough powder from bark respectively.The same result was got for the Chinese fir,the increasing rate is 53.9% 104.0%,42.9% respectively.The medium made up from the pine leaves is the second one for the pot.The difference is obvious in statistics.According to the relative analysis,the unit weight and hole rate of the medium are the most important factors for the seedling.Both the total and effective content of phosphine is the second most important factor.The response to each factor is the same in both species,except having different demand for nutritive element.The phosphine is much more important for the Masson pine,while Chinese fir is sensetive to nitrogen.The mediums made up from Bamboo or pine leaves have suitable physical condition,which make seedling grow well and fungulizm earlier.
