Effects of different K fertilizers on the yield and the contents of amino acids of Pleurotus tuber-regium,s sclerotium
不同钾肥对虎奶菇菌核产量与氨基酸含量的影响

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.
