通过对镰刀菌生长、产毒条件的观察，发现镰刀菌生长、产毒与环境条件关系密切：适宜温度（２０℃～３０℃）、湿度（４０％）条件下，真菌生长旺盛，孢子数量多；碱性（ｐＨ＞７．０）条件则明显抑制其生长，孢子数量也减少；无机元素对生长无影响；低温尤其是变温条件下，镰刀菌易产生Ｔ－２毒素；碱性条件可明显抑制真菌产毒；温度、湿度和ｐＨ之间存在明显的交互作用 Through the observation of Fusarium growth and producing toxin, it was found that Fusarium growth and toxin production were closely related to environmental conditions: under the suitable temperature (20 ℃ ~ 30 ℃) and humidity (40%), the fungus grew vigorously with more spores ; Alkaline (pH> 7.0) conditions significantly inhibited the growth, the number of spores also reduced; inorganic elements had no effect on growth; especially under variable temperature conditions, Fusarium easily produce T-2 toxin; alkaline conditions can be significant Inhibition of fungal toxin production; there is a clear interaction between temperature, humidity and pH
