摘  要：
以陕西省大柳塔矿采煤沉陷地为试验地,自然状况下接种丛枝菌根真菌,研究了丛枝菌根对沙棘生长及根系发育的影响,并对接菌后根际微环境变化进行了探讨。结果表明:接菌处理植株地上和根系发育生长指标优于不接菌组。接菌后宿主植物与菌根能形成良好的共生关系,根际菌丝密度远高于对照。接种丛枝菌根增加了土壤微生物数量,提高了根际土壤磷酸酶活性,土壤速效养分含量也高于不接菌组。接种菌根对采煤沉陷地土壤具有一定的土壤改良效果,改善了土壤根际微生态环境,取得了较好的生态效益,对当地的生态修复具有重要意义。

摘  要：
Taking Da Liuta coal mining subsidence land in Shannxi province as the studied area,effect of arbuscular mycorrhizal fungi inoculation on Hippophae rhamnoides growth and rhizosphere microenvironment changes under natural conditions were analyzed.The results showed that the plant aerial part and root growth indexes of the inoculation treatment were better than those of control treatment.After the inoculation host plants and mycorrhizal could form good symbiosis,rhizosphere mycelium density were much higher than control treatment.Arbuscular mycorrhizal inoculation increased the quantity of soil microorganism and content of available soil nutrient.Arbuscular mycorrhizal inoculation could improve soil nutrient and root microenvironment,could obtain better ecological benefits,which was great significance to the local ecological restoration.
