在棉花生产中使用农药较多,特别是使用剧毒农药“1059”、“3911”及不易分解的“滴滴涕”、“六六六”农药,最易污染环境及棉株,利用棉子壳培养的食用菌,在它的子实体内有无农药残留?食用后对人体有无危害?这是很多人关心的一个问题。早在七十年代,我们利用棉子壳培养食用菌成功后,就碰到了这个问题。当时,我们没有科学化验手段,经饲喂动物试验,结果没有异常现象。然而,我们自己由小量到大量的试验性食 In the cotton production more pesticides, especially the use of highly toxic pesticides “1059”, “3911” and difficult to decompose “DDT”, “BHC” pesticides, the most easily pollute the environment and cotton plants, the use of cotton seedling culture Of edible fungi in its fruiting body without pesticide residues?
