摘  要:
2009~2010年从采自漾濞彝族自治县的500份核桃根际土壤样品中分离到3个属18种捕食线虫真菌,其中检出频率较高的是Arthrobotrys musiformis和Monacrosporium thaumasium,检出率分别为16.97%和12.96%。通过对四个季节捕食线虫真菌多样性分析,发现夏季和秋季的物种多样性指数较高,分别为2.38和2.35;其次是春季,为2.00;冬季的相对较低,为1.76。在所有检测到的捕食线虫真菌中,产黏性网的捕食线虫真菌占77.78%。

摘  要:
500 soil samples were collected from walnut rhizosphere at Yangbi county in 2009 and 2010,and investigated for nematode-trapping fungi.18 species which were assigned into 3 genera were isolated.Arthrobotrys musiformis and Monacrosporium thaumasium were dominant species,with their positive rate was 16.97% and 12.96%.The diversity of nematode-trapping fungi was higher in summer and autumn,as the diversity index was 2.38 and 2.35 respectively.The diversity index in winter was 1.76,which was lower than other seasons.The species forming adhesive nets were dominant,the positive rate of them was 77.78%.
