摘 要:通过对陕西人工竹林内凋落物中不同层次真菌的采集、分离培养,共鉴定出真菌48属(种),其中L层23属(种)F_1层22属(种),F_2层20属(种),H层19属(种)。这些真菌中鞭毛菌亚门占2.1%,接合菌亚门占8.3%,子囊菌亚门占10.4%,担子菌亚门占12.5%,半知菌亚门占68.8%。凋落物中的真菌在组成和数量上存在明显的随层次加深由寄生到腐生的演替现象。From the isolated culture of fungi to each litter layer of bamboo in Shaanxi and identified 48 genera (Species) of fungi. There are 23 genera (Species) in L layer, 22 genera (Species) in F1-layer, 20 genera (species) in F2- layer and 19 genera (species) in H- layer. The percentage of the identified genera in each subdivision are as following: Mastigamycatina was 2. 4, Zygomycotina was 8. 3, Ascomycotina was 12. 5,and Deuteromycotinavras 68. 8, the studies also showed that there is a succession of the fungi composition and relative quantity as the layer goes deeper, parasitic fungi is lessen and saprophyte is increase.
