摘要
通过盆载接种和离体根接种．证明上海唐菖蒲根腐病由Ｆｕｓａｉｕｍｏｘｙｓｐｏｒｕｍ；Ｆ．ｓｏｌａｎｉ，Ｆ．ｓｐｐ．引起．并且证实球茎和土壤都能带菌．球茎切面伤口用不同方法促进愈合，然后接种病原．结果表明对病菌侵染有不同抑制作用．田间用加深排水沟，球茎浸药，球茎随采收随收贮．前期保温保温，后期常用保湿贮藏等措施防治唐菖蒲根腐病．使唐菖蒲球茎贮藏后后完好率和品质显著提高，播种后出苗和成苗过程中生长旺盛．成花率提高，并增产出相应致量的大球茎，经济效益明显．
According to inoculating on detached root and Pot plants,the pathogens of Gladiolus root rot,including Fusarium oxysporum F.solani and F.spp.are evidenced in Shanghai. The Pathogens are carried by corms and soil. Different temperatures in saturated relative moisture for wound healing prevent fungi infection significantly.Deepening the drainage system,dipping corms in fungicide, storing the corms instantly after plucking. maintaining the temperature and saturatcd relative at the earlier stage, maitaining normal tempetature.high relative moisture at the later stage and so on to control the root rot of gladiolus corms attain better quality of corms,a good seedling, more cutting flowers and more large corms. The economic value of this control method is van significant.
