小麦“三锈”、白粉病的严重为害,是我州小麦高产、稳产的巨大障碍,历年造成小麦减产轻则10%~20%,重则50%以上。研究小麦“三锈”、白粉病的发生、发展规律以及病菌生理小种的变化消长规律,选用抗病良种用于生产是一项经济有效的措施。从1987年开始,我们协
Wheat “three rusts”, powdery mildew seriously damaged, is a huge obstacle for high yield and stable yield of wheat in our country. Over the years, the wheat yield is reduced by 10% -20% and the weight is more than 50%. It is a cost-effective measure to study the “three rusts” of wheat, the occurrence and development of powdery mildew and the changes of the physiological races of pathogenic bacteria. Since 1987, our association
