甘蓝枯萎病于2001年最先在北京延庆发现~([1]),目前已扩散到山西、河北、甘肃及陕西等北方甘蓝生产基地,重病区发病率高达80%以上,对甘蓝生产造成了严重的威胁。国内外对甘蓝枯萎病寄主范围的研究仅限于十字花科作物~([2-4]),对该病原菌是否侵入其他类蔬菜及1、2号生理小种侵染十字花科寄主的差异尚未见报道。本文采用人工接种的方法,综合分析甘蓝枯萎病菌对主要大田蔬菜作物的侵染寄生能力,为制定合理的轮作防病
Cabbage blight was firstly found in Yanqing, Beijing in 2001 ~ ([1]). It has spread to cabbage production bases in northern China such as Shanxi, Hebei, Gansu and Shaanxi. The incidence of severe cabbage is over 80% Serious threat. Domestic and international research on the host range of cabbage wilt disease is limited to cruciferous crops ~ ([2-4]), the pathogen is not invaded other vegetables and No. 1,2 physiological races infected crucifer host differences have not yet See report. In this paper, artificial inoculation method, a comprehensive analysis of cabbage Fusarium oxysporum major field vegetable crops infestation parasitism, in order to develop a reasonable rotation disease prevention
