Seven plots selected from wanglang reserve were distributed in different types of forest and at different altitude, and different plot has different microclimate. soil property, microbial population, soil nutrient content of forest soil were determined in wanglang natural reserve, from may to october 2002 to july 2003, the ecological distribution of three main groups, bacteria, actinomycete and fungi were determined in the forest soils by the cell enumeration methods. six kinds of physiological groups, including ammoniation bacteria, nitrification bacteria, nitrosification bacteria, aerobic autogenesis azotobacter, aerobic cellulose - decomposing bacteria and anaerobic cellulose - decomposing bacteria were enumerated by the most - probable number ( mpn )
2001年10月在王朗自然保護區內設立了3個定位研究樣地和4個臨時樣地，通過多次現場采樣與室內實驗分析，測定了白樺林、岷江冷杉林、紫果雲杉林、繡線菊-羊茅群落、羊茅群落及高山柳灌木叢等6種不同植物群落內土壤微生物三大類群數量、功能微生物數量、土壤養分，並在固定樣地內使用埋袋法進行了三個埋藏深度的凋落物分解袋試驗，初步研究了枝條、闊葉、針葉等凋落物組分在不同分解階段所含養分的動態變化。Taken two heavy metal contaminated soils in copper mine field of hongtoushan area and lead - zinc mine field of qingchengzi area as sampling sites, studied the abundance and diversity of amf community and the relation of which to ecological factors ; two experiments were managed by pot culture and four - compartments culture system with festuca. rubra and red clover as host plants inoculated with gintraradices, gmosseae and gcaledordinum to study the effect of different amf on the uptake and accumulation of heavy metal in cd contaminated soil and cu > zn - pk cd complex - contaminated soil
採用盆栽、四室根箱培養的方法，研究了接種g . intraradicesg . mosseae和g . caledordinum在cd污染和cu 、 zn 、 pb 、 cd復合污染土壤中對紫羊茅、三葉草吸收、累積重金屬的影響，明確了叢枝菌根菌在重金屬污染土壤生物修復中的作用。主要結果如下： 1 、沈陽礦區重金屬污染土壤中，共發現叢枝菌根菌6個屬23個種，已鑒定22種， 1個未定種。The colonization of gintraradices, gcaledordinum and gmosseae can decrease the uptake and accumulation of heavy metals of festuca. rubra and red clover and then protect them from toxicity of heavy metals to some extent. there were consistent difference amongthe effect of different amf species, gintraradices had better effect on the decrease of heavy metal content in shoot of host plants than gcaledordinum and gmosseae
能明顯降低紫羊茅、三葉草體內重金屬山根系向地上部的運輸，在某種程度上減少了高濃度重金屬對植株的影響，有利於紫羊茅和三葉草在重金屬污染土壤中定植。不同菌種的菌根效應有較大差異，菌種gintraradice :在減少重金屬由根系向地上部運輸的作用上優于菌種gcaledordinum和gm口sseae 。The thesis approve research objects have representative character and universality after systematic analysis of zoology adaptability of poa pralensis, red fes cue and target percnnia ryegrass
本文在系統地分析了黑麥草、紫羊茅和早熟禾的生態適應性后，進一步證實了研究對象具有典型性和普遍性。分享友人
