宁夏贺兰山农牧场温室蔬菜根际土壤线虫的初步鉴定

Research on Rhizosphere Soil Nematode on Vegetable in Greenhouses of Helanshan Farm in Ningxia

于2009年7-8月,对3种宁夏贺兰山农牧场温室蔬菜即黄瓜、辣椒、茄子的根际土壤线虫进行了取样、线虫分离和形态鉴定等研究。结果表明：该地根际土壤线虫有3个目、3个亚目1、0科1、3个亚科的21个属;在西北地区,由于棚室蔬菜大面积种植为根际土壤线虫的繁殖提供了良好的生活环境,尤其是棚室蔬芽复种指数的增加使得根际线虫的种类和数量逐年增多。

By nematode isolation and morphological identification on rhizosphere soil of three kinds vegetables in greenhouse（cucumber,pepper,eggplant） of Helanshan farm in ningxia.The results showed that the nematodes in rhizosphere soil had three objectives,three sub-orders,10 families,13 subfamilies,21 genera.In the northwest area,as a large area cultivation in greenhouse vegetable,the nematode reproduction in rhizosphere soil provides a good living environment,especially the increase in greenhouse cropping index makes the foundation of the type and number of nematodes
