不同钾肥对虎奶菇菌核产量与氨基酸含量的影响

Effects of different K fertilizers on the yield and the contents of amino acids of Pleurotus tuber-regium^,s sclerotium

摘要: 运用灰色系统理论，探讨了不同K肥相同含K量添加培养料栽培虎奶菇菌对产量与不同种类氨基酸总量的影响。结果表明，以硝酸钾为K肥对虎奶菇菌核产量与氨基酸含量影响的关联度最大，其次为氯化钾处理，硫酸钾处理关联度最小，这与栽培试验结果相一致。

Abstract: Effects of different kalium fertilizers on the yield and the contents of amino acids of Pleurotus Tuber-regium's sclerotium were studied with the grey-system theory. The results show that the correlative coefficient between the yield, the content of amino acid of Pleurotus Tuber-regium's sclerotium and KNO₃ treatment is highest, KCl treatment is the second.The correlative coefficient of K₂SO₄ treatment is the minimum,which is consistent with the experimental result.
