硫酸锌浓度对香菇生长发育的影响

Effects of Zinc Sulfate on Growth and Yield of Lentinula edodes

在香菇栽培料中加入不同浓度的硫酸锌（ZnSO4.7H2O）,观察香菇菌种萌发、菌丝生长、子实体产量以及霉菌污染等情况,并检测不同处理收获的子实体中的锌含量。结果表明,一定浓度的锌离子能促进香菇菌丝生长,提高香菇产量,并对霉菌污染有一定的抑制作用。硫酸锌添加量为500-600 mg/kg干培养料,香菇菌丝体长势、子实体产量和富锌量均最佳。当硫酸锌添加量为500 mg/kg时,香菇子实体含锌量最高（172 mg/kg）。

Added zinc sulfate in different content into the material to culture Lentinula edodes. Then watched the growth and yield of Lentinula edodes and measure the content of zinc sulfate in Lentinula edodes. The results showed that the zinc ion of certain density could promote the mushroom hypha growth, improved the output of Lentinula edodes, and there was certain inhibition on the mildew pollution. The suitable density of the zinc sulfate was 600 mg/kg.
