摘要
利用泡囊丛枝状菌粮（ＶＡＭ）菌对慢生型树种南洋杉幼苗进行人工接种，１年后的测试结果：接种ＶＡＭ处理的幼苗其菌根感染率达１００％，而对照株仅自然感染１０．３％；接种处理幼苗的生长与对照比较，平均高增加３６．５％、地径增加１６．６％、平均冠幅增加３６．７％、枝条数目增加５６．７％；接种株的生物量与对照比较，地上部分平均干重增加１００．５２％、地下部分干重则增加１５５．７６％。表明地表球囊霉９００４菌株对南洋杉幼苗的促生增产效果十分明显。
The seedlings of Araucaria cunninghamia in containers were inoculatied with VA mycorrhiza fungi,Clomus epigaeum(9004).The rate of infection was 100% after transplanting in one year.The height accretion,diameter at ground level,crown and branch number of the seedlings were increased by 36.5%,16.6%,36.7% and 56.7% respectively compering with the of control.And the dry weights of above-ground and root of seedling were increased by 100.52% and 155.76%.This suggests that inoculated with VA mycorrhiza can greatly enhance the growth of the seedlings.
