采用菌根接种,促进金合欢树苗生长在埃塞俄比亚金合欢树木苗圃中,对标准无菌土壤用囊枝状菌根真菌(VAM)和当地植物根接种,然后进行苗木生长对照试验。苗木分别在不同土壤中生长3～4个月后,调查其生长差异。结果显示,在同时采用热带 VAM 和当地植物根系接种处理的土壤中,苗木嫩枝干重与标准土壤中苗木相比,分别提高了48.33%和36%。而采用温带的VAM 接种处理的土壤,对苗木生长无明显促进作 Using mycorrhizal inoculation to promote the growth of acacia saplings in Ethiopian acacia tree nurseries, the standard sterile soil was inoculated with VAM and local plant roots, followed by seedling growth control trials. Seedlings were grown in different soils 3 to 4 months after the investigation of their differences in growth. The results showed that the shoot dry weight of seedlings increased by 48.33% and 36%, respectively, compared with the standard soil seedlings in the soil with both tropical VAM and local plant root inoculation. The use of temperate VAM inoculation of soil, no significant promotion of seedling growth
