马铃薯是我区的重要冬菜。但近年来,由于病害蔓延(发病率50—70%),减产严重,尤其是乌鲁木齐、昌吉州的一些社队,马铃薯单产已由原来的2,000—3,000斤下降到800—1,000斤,有的甚至收不回种子。为了弄清我区马铃薯主要病害的病原、病症及防治方法,我所一九七七年派员到乌鲁木齐县达板城公社西沟二大队二小队,与当地科研小组及由内蒙来的技术员,一起种植病薯,分离和接种病原菌,并对病菌进行生理生化测定,证明当地马铃薯生长期间严重死苗主要是黑胫病和环腐病侵染所致。 Potato is an important winter vegetable in our district. However, in recent years, due to the spread of diseases (the incidence rate of 50-70%), serious cuts have taken place. In particular, some communes and units in Urumqi and Changji Prefecture have reduced their yields to 800-1,000 kg from 2,000-3,000 kg, and some even Seeds can not be received In order to clarify the pathogen, disease and prevention methods of the main diseases of potato in our district, in 1977, we dispatched two teams to the second team of the Xigou No.2 Brigade in the Banban Commune of Urumqi County. In cooperation with the local scientific research team and technicians from Inner Mongolia, The pathogenic bacteria were isolated and inoculated and the pathogenic bacteria were isolated and inoculated. The physiological and biochemical determination of the bacteria showed that the severely dead seedlings were mainly caused by blackleg and ring rot during the growth of the local potato.
