【摘要】 从不同林型下分离获得的外生菌根真菌纯培养菌株中 ,选择了其中劣味乳菇、赫丝膜菌、褐环乳牛肝菌、毛边滑绣伞4株优良菌种 ,对油松人工幼林(5年生)进行菌剂混合接种试验。结果表明 :采用外生菌根真菌对油松幼林接菌 ,能够使土壤微生物种群数量发生变化 ;接菌后的土壤中的细菌、真菌、放线菌总数比不接菌的有明显的增加 ,其中真菌增加732.35 %。对接菌油松进行菌根侵染调查发现 ,接菌后的油松菌根侵染率为75 % ,不接菌的为20 % ;对连续两年接种菌剂的油松幼林调查发现 ,与不接菌剂的相比施用菌剂的油松地径、株高显著增加。由此认为 ,外生菌根真菌作为一项生物接种技术对促进油松幼林的生长具有重要作用更多还原

【Abstract】 In ectomycorrhiza fungi strain separated from the different forest types, Lavteriuslsus Fr., Cofinarus russus Fr., Suillus lufeus(L.) Grsyand hedloma mesophaeum (Fr.)Quel were chosen, and inoculated to man-made Pinus tabulaeformis Carr. Forest whose age was 5. The results showed that: Population quantity of microbe changed after inoculation, the total quantity of bacteria,fungi and actinomycetes were obviously more than that of uninoculation, fungi increase 732.35% in the young Pinus tabulaeformis Carr. Forest inoculated by mycorrhizal fungi. Through investigation, we found the ratio of mycorrhizal invasion was 75% after inoculation, however that of uninoculation was 20%. Investigating increment of Pinus tabulaeformis Carr.Forest inoculated in a series of two years, we found that using strain can increase the growth in basal diameter and DBH(diameter at breast height). So mycorrhizal fungi can act as a bio-inoculation technology, it owns important ecologial benefits in reforming low value forest.更多还原
