摘　　要：为研究不同无机氮源对姬松茸产量及氨基酸含量的影响,采用碳酸氢铵、硫酸铵和尿素3种无机氮源栽培福姬5号,并对其产量和各类氨基酸含量等指标进行分析。结果表明:以碳酸氢铵为无机氮源的福姬5号子实体产量最高,且与硫酸铵和尿素处理间差异达到极显著水平,其子实体中17种氨基酸含量均高于尿素和硫酸铵处理,其中谷氨酸、缬草氨酸、甲硫(蛋)氨酸、异亮氨酸、亮氨酸和精氨酸含量分别比尿素和硫酸铵处理含量高11.05%、10.61%、11.83%、11.01%、12.22%、17.83%和34.51%、35.19%、21.94%、34.44%、34.67%、40.74%;各类氨基酸总量均高于尿素和硫氨酸处理,其中鲜味氨基酸总量、支链氨基酸总量、儿童氨基酸总量、必需氨基酸总量分别较尿素和硫酸铵高9.04%、11.40%、17.32%、9.80%和32.26%、34.77%、38.16%、30.84%。说明3种无机氮源中,碳酸氢铵最适宜用于姬松茸栽培。Effects of different inorganic nitrogen sources on Agaricus blazei yield and amino acid contents were studied.Fuji No.5 was cultivated with three inorganic N sources,including NH_(4)HCO_(3),(NH_(4))_(2)SO_(4)and CO(NH2)_(2).And its yield and contents of various amino acids were analyzed.The results showed that the yield of Fuji No.5 cultivated with NH_(4)HCO_(3)was the highest,which was higher than that of Fuji No.5 with(NH_(4))_(2)SO_(4)and CO(NH2)_(2)as inorganic N source,and the difference between treatments reached extremely significant level.Aspartic acid,glutamic acid,valine,methionine,isoleucine,tyrosine and histidinewere 11.05%,10.61%,11.83%,11.01%,12.22%,17.83%and 34.51%、35.19%、21.94%、34.44%、34.67%、40.74%higher than CO(NH2)_(2)and(NH_(4))_(2)SO_(4)as inorganic nitrogen sources,respectively.The total amount of amino acids was higher than Fuji No.5 with(NH_(4))_(2)SO_(4)and CO(NH2)_(2)as inorganic N source,among which,sulfur amino acids,branch chain amino acids,children amino acids and essential amino acids were 9.04%,11.40%,17.32%、9.80%and 32.26%、34.77%、38.16%、30.84%The results showed that NH_(4)HCO_(3)was the most suitable inorganic N source for Agaricus blazi.
