一九五一年春,我参加了四川省棉花枯萎病防治研究协作组,到射洪县驻点,一方面学习当地棉农和棉花病虫害作斗争的经验,另一方面和协作组的同志一道,对涪江流域棉区的棉花枯萎病蔓延流行情况、病菌及病株的农业生态系等进行调查研究,摸清环境条件、栽培技术等与棉株的生长发育和病菌的发生发展的相互关系,从而提出有效的防治措施。经过多年的科学研究和生产实践证明,防治棉花枯萎病的根本途径是以选育、种植抗病品种为中心,结合加强栽培管理等一整套综合协调防治措施。现将本人参加这一工作的情况和体会简述如下。研究工作一开始,我们就对当时国内外
In the spring of 1951, I participated in the Collaboration on Cotton Fusarium Disease Prevention and Control Research in Sichuan Province and went to Shehong County to set a spot where I learned about the experience of local cotton farmers in combating cotton pests and diseases. On the other hand, Epidemic situation of Fusarium wilt in the cotton area of Fujiang River Basin, and the agroecosystems of pathogens and diseased plants were investigated to find out the relationship between environmental conditions, cultivation techniques and the growth and development of cotton plants and the occurrence and development of germs Put forward effective prevention and control measures. After many years of scientific research and production practice has proved that the fundamental way to combat cotton blight is breeding, planting resistant varieties as the center, combined with strengthening the cultivation and management of a comprehensive and coordinated prevention and control measures. Now I participate in the work of the situation and experience outlined below. At the beginning of the research work, we at home and abroad at that time
