在０，５，１０℃下人工接种８种大白菜贮藏期主要真菌分离物。结果有５种可在１０℃的条件下侵染大白菜。其中甘蓝链格孢、希金斯刺盘孢及灰葡萄孢可在０～５℃下产孢。而芸薹链格孢、萝卜链格孢则仅在１０℃条件下可以产孢。鉴于管理正常的传统型及强制通风型大白菜窖的窖温一般不超过５℃，故带入窖中的芸薹链格孢及萝卜链格孢可侵染白菜而不能产孢。因此在北京郊区引起大白菜烂窖的黑斑病的发生程度，主要决定于田间携入病菌量的多少。希金斯刺盘孢、甘蓝链格孢、灰葡萄孢在０℃下能产孢，因此，这几种菌的菌量在上述两种窖中仍可增加。田间携入量与病害在窖中的发生程度关系较上述两种菌要小。控制窖温对抑制这些病菌在窖中的蔓延有着重要的意义。
The main fungal isolates of eight kinds of Chinese cabbage were inoculated at 0, 5, 10 ℃. There are 5 species that can infect cabbage at 10 ° C. Alternaria alternatus, Higgins spore and Botrytis cinerea sporulation at 0 ~ 5 ℃. Alternaria brassicae, Alternaria alternata can sporulation only at 10 ℃. In view of the normal management of traditional and forced ventilation cabbage cellar temperature generally does not exceed 5 ℃, so into the cellar Alternaria brassicae and Alternaria alternata can infest cabbage and sporeless. Therefore, the occurrence of black spot in the rotten caves of Chinese cabbage in the suburbs of Beijing mainly depends on the amount of bacteria carried in the field. Higgins spore, Alternaria alternata, Botrytis cinerea sporulation at 0 ℃, therefore, the bacteria in these two kinds of bacteria in the two pit can still increase. Field carrying amount and disease incidence in the pit than the two kinds of bacteria to be small. Control of pit temperature on the inhibition of these bacteria in the cellar in the spread of great significance.
