摘要
研究了大叶黄杨和金叶女贞的根际与根外主要微生物类群的数量与季节变化。结果表明:二者根际与根外土壤微生物以细菌占绝对优势,其次为放线菌和真菌。根际中三大类微生物的数量均比相应的根外多,根际效应明显,而且细菌的根际效应最大。大叶黄杨和金叶女贞对细菌与微生物总数的根际效应都是春季>夏季>秋季>冬季,但二者根际环境的不同使其对放线菌与真菌的根际效应也不同。
It studied rhizosphere microorganisms and root outside the main taxa of the quantity and seasonal variation in of Euonymus japonica and Ligustrurn vicaryi. The results showed that bacteria absolute advantage in both rhizosphere and root outside the soil, followed by actinomycetes and fungi. Three categories the number of micro-organisms of the Rhizo- sphere than those outside the root of the corresponding number, rhizosphere effects are more obvious, but the biggest effect of the rhizosphere bacteria. The total number of bacteria and microorganisms in rhizosphere effects of Euonymus japonicus and Ligustrurn vicaryi are spring 〉sunarner〉 autumn〉 winter, But both rhizosphere of different environments to make them actinomycetes and fungi in rhizosphere effect was also different.
