本文通过在高美施培养基中添加不同浓度的硫酸锌对三个供试平菇菌株的生理反应试验，证明锌是促进平菇菌丝生长发育和生物合成的微量元素之一；发现高美施对平菇母种菌丝吸收利用锌元素有增效作用；不同品种对锌营养的需求不同，200×10－6的硫酸锌是促进平菇菌丝生长发育所需的最佳锌营养条件。
In this paper, by adding different concentrations of zinc sulfate in high Meisch culture medium to three strains of Pleurotus ostreatus physiological response test showed that zinc is to promote Pleurotus ostreatus growth and development of one of the trace elements and biosynthesis; found that the United States Shi mushroom mushroom mycelium absorption and utilization of zinc synergistic effect; different varieties of zinc nutrition needs of different, 200 × 10-6 of zinc sulfate is to promote Pleurotus ostreatus growth and development of the best zinc nutrition requirements .
