摘要
调查了亚麻白粉病在新疆的发生及危害情况,对亚麻白粉病病原菌及田间发生规律进行了初步研究。调查表明,亚麻白粉病在新疆亚麻种植区均有发生,是亚麻田的主要病害;亚麻白粉病的分生孢子在15-30℃均可萌发,20-25℃是适宜萌发温度,在自然条件下白粉病分生孢子侵染的潜育期为8 d;亚麻白粉病田间发生规律初步研究表明,新源县亚麻白粉病始发生期与6月上旬气温和降雨关系密切,气温低、降雨多的年份亚麻白粉病发生相对较晚。
The filed occurrence law and pathogen of flax powdery mildew were initially studied in Xinjiang, the occurrence and damage of flax powdery mildew in.Xinjiang was investigated. The results showed that the flax powdery mildew was a major disease of flax and widely occurred in flax planting area in Xinjiang. The pathogenic fungus of flax powdery mildew conidia can germinate in the temperature range of 15 -30℃, the opimn is 20- 25℃; The occurrence of flax powdery mildew has a familiar relation with air temperature and rainfall in Xinyuan., it occurred relatively to low air temperature and much rainfall in the first ten- day period of June.
