摘要:

目的:调查白马雪山牧场中捕食线虫真菌资源及其在不同基质中的分布情况。方法:2012年8月份从白马雪山牧场中
采集了97份牦牛粪样,95份土壤样品,进行捕食线虫真菌的分离培养及鉴定。结果:共分离出4属16种捕食线虫真菌,其中1种未定名,Arthrobotrys oligospora 和Arthrobotrys thaumasium 在土壤样品及牦牛粪便中都出现,频率较高。结论:土壤中的捕食线虫真菌比牦牛粪样中的丰富,具有三维菌网的Arthrobotrys 属菌株出现频率较高。

Abstract:

Objective: To investigate the species and distribution of nematode-trapping fungi in Baima Snow Mountain. Methods: 97 yak dung and 95 soil samples were taken from Baima Snow Mountain in August 2012 which were followed by isolated culture and identify work in lab. Results: 16 species including 1 unnamed species which belongs to 4 categories were isolated from samples. Among the isolated species, Arthrobotrys oligospora and Arthrobotrys thaumasium both were found in soil and yak dung with high occurrence. Conclusion: The species isolated from soil samples were much richer than yak dung. Species with adhesive nets were high frequently found.

Key words: Baima Snow Mountain, yak dung, nematode-trapping fungi, soil, resource
