根据一九五一年我们与山西省农业病虫防治总站,山西省农事试验场及山西农学院在北京,太原及太谷合作试验结果,榖子白发病的传染来源是以土壤为主,病户土壤的传染力可达百分之廿二;病户种子传染最多的仅达百分之十,一般约为百分之二;病户土粪传染力不过百分之三,因此用拔除白尖法来消灭病菌卵孢子的散布在目今是个合适的办法,各地反映也还容易推行。但是还有些技术上面的问题须要加以决定,我们针对这些问题做了些观察,可以初步解答如下:
According to the experiment conducted in 1951 in collaboration with Shanxi Agricultural Pest Control Station, Shanxi Agricultural Experiment Station and Shanxi Agricultural College in Beijing, Taiyuan and Taigu, the source of the infection of Baizi white disease was soil-based disease The infectivity of soil in the households reaches as high as 22%; the maximum number of infected patients is only 10% of the total, about 2% in general; however, the infectivity of soil sick households is only 3% Spike method to eliminate the spread of pathogen spores in the present is a suitable solution, reflected everywhere is also easy to implement. However, there are still some technical problems that need to be decided. We have made some observations on these issues and can be initially answered as follows:
