馬鈴薯瘡痂病綜合防治策略

摘 要：多年連作引起馬鈴薯瘡痂病發(fā)生嚴重，而生產(chǎn)中缺乏抗性品種和專用防治藥劑，使病害防治困難。研究從引起馬鈴薯瘡痂病的致病鏈霉菌分類及致病因子特性、馬鈴薯抗性品種及鑒定方法、土壤理化性質(zhì)及土壤微生態(tài)3個角度分析瘡痂病的發(fā)生特點，提出瘡痂病綜合防治策略，為瘡痂病發(fā)生機理研究及田間綜合防控提供思路。

Integrated Control Strategy of Potato Scab

Abstract Many years of continuous cropping caused the serious occurrence of potato scab， and the lack of resistant varieties and special control agents in production made it difficult to control the disease. The occurrence characteristics of scab disease are analyzed from three aspects： the classification of Streptomyces causing scab disease and the characteristics of pathogenic factors， the resistant varieties of potato and identification methods， the physical and chemical properties of soil and soil microecology. A comprehensive control strategy for scab disease is proposed， which provided ideas for the study of the pathogenesis of scab disease and the comprehensive prevention and control in the field.
