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

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。

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, KCI treatment is the second. The correlative coefficient of K2SO4 treatment is the minimum, which is consistent with the experimental result.
