本文报道在高ｐＨ值地区进行大白菜根肿病苗期人工接种抗病性鉴定的方法。试验表明，可用ｐＨ５．５的南方花卉营养土作培养基质，以１０００倍显微镜下，每视野有１０个休眠孢子囊浓度的悬浮液浸根接种，在人工控制ｐＨ值到５．５的条件下培养。我们于１９８７年开始用此方法对５份大白菜一代杂种进行了抗病性鉴定，结果表明此方法是可行的。
This paper reports the method of artificial inoculation resistance identification of Chinese cabbage clubroot disease in high pH region. Experiments show that the culture medium can be used southern flower nutrition pH5.5 culture medium to 1,000 times the microscope, each field has a suspension of 10 resting sporangium concentration immersion root inoculation, under the conditions of artificial pH control to 5.5 to cultivate. We started in 1987 with this method on five Chinese cabbage generation of hybrids were identified, the results show that this method is feasible.
