摘  要：
为了探究褐环乳牛肝菌与绿木霉复合接种对樟子松根际土壤生物活性年际变化的影响,本研究采用盆栽试验法,调查了接种外生菌根菌——褐环乳牛肝菌(Suillus luteus)N94和绿木霉(Trichoderma virens)T43对樟子松(Pinus sylvestris var.mongolica)苗木根际土壤酶(过氧化氢酶、脲酶和碱性磷酸酶)、微生物数量(细菌、真菌和放线菌)和土壤养分(氮、有效磷和速效钾)的年际变化。结果表明:复合接种N94与T43可以有效发挥协同增效作用,该处理组的根际土壤酶、土壤微生物数量和土壤养分等均得到提高,所测试的各项指标(除2013年土壤氮外)均优于单接种处理组,且这种提高具有一定的持久性,年度变化显著。本研究可以为植物根际益生菌改良土壤生物活性、有效提高苗木生长质量提供数据参考。

摘  要：
To investigate the effects of compound inoculation on interannual changes of bioactivity of Pinus sylvestris var. mongolica rhizosphere soil,a pot experiment was carried out to examine the interannual variations of soil enzyme activities( catalase,urease,and alkaline phosphatase),the quantity of microorganisms( bacteria,fungi,and actinomycetes),and soil nutrient concentrations( total nitrogen,available phosphorus and available potassium) in the rhizosphere of P. sylvestris var. mongolica seedlings after inoculated with ectomycorrhizal fungi Suillus luteus N94 and Trichoderma virens T43. The results showed that the compound inoculation of N94 and T43 exhibited a synergistic effect,with the soil enzyme activities,microbial quantity,and soil nutrients of rhizosphere being enhanced. All measured variables( except for total soil nitrogen in2013) performed better in the compound inoculation treatment than in the single inoculation treatment. Such better performance consisted,but with significant inter-annual variations. Our results provide a reference for improving soil biological activity of probiotics and the growth of seedlings.
