Abstract


The study in 2003-2004, Jilin Province Black Soil cornfield soil as the research object, using the dilution plate method, soil particles leaching method and soil plate method by different methods of Jilin Province, elm, Dehui, Changchun and Gongzhuling Black Soil Corn Land 108 in four cities-like soil fungal isolates from 131 strains isolated and identified, fauna and ecological characteristics of the parts soil samples at the same time. The floristic research from soil fungi advantage is a number of soil fungi and genera, species seasonal dynamics, the number of soil fungi and genera, species vertical variation distribution analysis and discussion. Ecological characteristics under different fertility of black soil in maize reproductive period the number of fungi and six kinds of environmental factors (soil moisture, soil pH, soil organic matter, soil available nitrogen in the soil available phosphorus and soil potassium) between and the Black maize soil fungal flora in different tillage fertilization measures change. The classification study identified 25 genera, 55 kinds of four variants. Of which 14 kinds are newly recorded species of Jilin Province. 25 are respectively Acremonium Link Acremonium of Alternaria Nees Alternaria, case Arthrobotrys Corda Arthrobotrys genus Aspergillus, Aspergillus (Mich.)
