寄主与病原物相互关系的定量研究工作中,难于解决的是定量接种。其难点有二:一是难于准确地在植株上接种一定的菌量;其次是无法检查接种到植株上的病原菌孢子数。我们从研究小麦的慢叶锈性的需要出发,在1982、1983两年探索叶锈菌定量接种方法,用“植株直接定量接种法”、“水洋菜薄膜定量接种法”和“空气压缩喷粉沉降纸片定量接种法”。经过两年几十次接种试验比较认为:“植株直接定量接种法”同一处理误差可达50％以上,无试验意义;“水洋菜薄膜定量
Quantitative study of the relationship between host and pathogen In the work, it is difficult to solve quantitative inoculation. The difficulty is twofold: First, it is difficult to accurately inoculate a certain amount of bacteria on the plant; followed by the inability to check the number of spores inoculated to the pathogen on the plant. Based on the study of the need of slow leaf rust of wheat, we explored the methods of quantitative inoculation of leaf rust in 1982 and 1983, using the methods of direct quantitative inoculation of plants, quantitative inoculation method of aquatic vegetables and air compression spray Powder sedimentation paper quantitative inoculation method. “ After dozens of inoculation experiments for two years, the author thinks that the same treatment error of ”direct quantitative inoculation of plants" can reach more than 50% with no experimental meaning;
