水稻白叶枯病一九五六年在我区发现,一九七一年已有九个县的42000余亩发病,成为水稻高产稳产的一大障碍。近年来,由于贯彻综合防治措施,各地不同程度的取得了防病保产的初步效果,在田间发病后,使用高效农药是防治的有效措施。我站同贫下中农和工人同志一起,于1972年对有关单位提供的多种新农药,在本站及汉中县新沟桥公社新校二队、南郑县草堰公社文革六队的秧田、大田的轻病田、重病田、接种田(面积共250余亩)进行了试验、示范、初步肯定了叶枯灵、叶枯青、7123、川-506、川-504的防病增产效果。现将试验、示范结果整理于后:
Rice bacterial blight In 1956, it was discovered in our district that over 42,000 mu of disease in nine counties in 1971 has become a major obstacle to the high and stable yield of rice. In recent years, due to the implementation of comprehensive prevention and control measures, the initial effect of disease prevention and protection has been obtained in varying degrees all over the country. After the onset of the disease, the use of highly effective pesticides is an effective prevention and control measure. I stood with the poor middle peasants and laborers together in 1972 on a variety of new pesticides provided by the relevant units in this site and the new bridge in Hanzhong County commune commune two teams, Nanzheng County Grassland commune Cultural Revolution six teams of seedlings, Field of light sickness, severe disease field, inoculation (covering an area of a total of more than 250 acres) were tested, demonstrating and initially affirmed Yeku Ling, Ye Kuqing, 7123, Sichuan-506, Sichuan -504 disease prevention and yield enhancement effect. Now test, demonstration results are arranged in the post:
