| 摘 要： | 2010年4-5月,于小麦抽穗至灌浆期,采用5点取样法,取根际5～20 cm土壤,运用漂浮法分离孢囊,统计100 g土孢囊数量,用生物形态学方法鉴定,结果表明,小麦禾谷孢囊线虫调查的39个县市中20个县市均有分布,南部县市尚未发现小麦孢囊线虫,关中地区发生普遍且较重.其中,周至县、岐山县、西安市临潼区、扶风县、眉县、杨凌、三原县、高陵县、泾阳县、华县的小麦禾谷孢囊线虫密度较大,每100g土壤的平均孢囊含量达9.8～63.0个.小麦孢囊线虫在陕西省分布广、危害严重,呈快速传播态势.这是首次报道陕西中南部地区小麦禾谷孢囊线虫的发生状况与分布,为陕西省全面防治小麦孢囊线虫提供依据. |

| Abstract: | Investigation on occurrence and distribution of Heterodera avenae in central-south Shaanxi province were carried out during wheat heading to milking stage in April to May 2010.Soil sampling were taken in five to twenty centimeters underground around the infected wheat plants in filed based on random sampling method of five-point.Cysts were isolated from one hundred grams of the mixed soil in terms of Fenwick's method.Identification of nematode was performed based on morphology characters of H.avenae.Of thir... |
