| 摘 要： | 对甘肃省嘉峪关市洋葱根际土壤线虫种类及其在洋葱生长期间的种群密度动态进行了研究，
结果表明，从洋葱根际土壤样品中共分离到植物寄生线虫2 目4 科5 属，非植物寄生线虫3 目5 科12 属。
各类线虫在洋葱移栽前数量最少，在洋葱鳞茎膨大期数量最多。燕麦真滑刃线虫（Aphelenchus avenae）
是该地区洋葱根际土壤植物寄生线虫的优势种，中杆属线虫（Mesorhabditis spp.）为该地区洋葱根际土壤
非植物寄生线虫的优势种。在洋葱的各个生长时期，洋葱根际土壤中非植物寄生线虫的密度均大于植物寄
生线虫。瓦斯乐斯卡指标（WI 值）为8.09，表明甘肃省嘉峪关市洋葱种植田土壤健康指数较高，土壤健
康状况良好。

| Abstract: | Species of nematodes in onion（Allium cepae）rhizosphere and its population density
dynamics were studied in Jiayuguan city of Gansu Province．The results showed that 2 catalogues，4
families and 5 genera of plant-parasitic nematodes and 3 catalogues，5 families and 12 genera of nonplant
parasitic nematodes were seperated．The number of various kinds of nematodes was the least
at onion pre-transplant time，while its number at onion enlargement period reached the peak．The
dominant species of plant-parasitic nematodes in this region was Aphelenchus avenae，while the nonplant
nematode was Mesorhabditis spp．During various onion growing period，the population density
of non-plant-parasitic nematodes in onion rhizosphere in Jiayuguan city was higher than that of plantparasitic
ones．Wasilewska index value was 8.09，indicating the health index of onion planted soil in
Jiayuguan city was higher，and the soil health condition was fine. |
