我国小麦根腐性病害研究现状及防治对策

 系统论述了我国小麦根腐性病害的研究现状，内容包括：（1）发生、分布及危害；（2）根病危害上升的原因；（3）病原学及发病规律；（4）根病防治对策。重点介绍了危害我国小麦的4类根病，即全蚀病、纹枯病、镰孢菌根腐病、蠕孢菌根腐病。小麦根病的防治应立足于土壤生态控制，增施有机肥和磷钾肥，选用抗耐病品种，实施健身栽培，以及应用三唑类内吸杀菌剂拌种。

THE PRESENT RESEARCH SITUATION AND CONTROL COUNTERMEASURE OF ROOT ROTS IN WHEAT

The present research situation of root rots of wheat in our country are discussed in this paper, which includes:(1) Their occurrence, distribution and harmness; (2)The reason for rising of root rots;(3) The aetiology and generation law of the diseases; (4)Controlling countermeasure to the diseases. There are mainly four kinds of root rots of wheat in our country: Take-all (Gaeumannomyces graminis), sharp-eye spot (Rhizoctonia spp.), root rot caused by Fusarium spp.and root rot caused by Bipolaris spp. The preventions to root rots of wheat should be aimed at soil ecology control, applying more organic fertilizer, phosphate fertilizer and potash fertilizer, breeding disease-resistant and enduring varieties. cultivation healthy population,using triazoles systemic fungicides to treat seed of wheat.
