近些年来,不少地区儿童缺锌的报告频频见诸报刊。人们通过对作物施用锌肥,提高作物的含锌量,由此改善食物链中的缺锌状况。也有不少在食用菌培养基中施用锌素的试验,但一般都侧重于产量的提高上,还未见到食用菌富锌和耐锌能力的报导。本文以平菇(Pleurotus ostreutus)为研究对 In recent years, many areas of zinc deficiency in children’s reports frequently seen in newspapers. Zinc fertilizers have been used to increase the zinc content of crops, thereby improving zinc deficiency in the food chain. There are also many tests on the use of zinc in edible fungi culture medium, but generally focus on the increase of yield, but have not yet seen the report of zinc-rich and zinc-resistant ability of edible fungi. Pleurotus ostreutus is the research object in this paper
