不同培养料对姬菇产量和品质的影响

Effect of Different Composts on the Yield and Quality of Pleurotus cornucopiae

比较分析了以闽牧 4 2、蔗渣和稻草为主料栽培的姬菇产量、生物学效率和蛋白质及氨基酸含量。结果表明 ,闽牧 4 2培养料栽培的姬菇 ,生物学效率最高 ,为 1.14。变量分析表明 ,闽牧 4 2培养料栽培的姬菇比稻草培养料栽培的姬菇增产 6 0 .11% ,差异达极显著水平 ;比蔗渣培养料栽培的姬菇增产 19.2 8% ,差异达显著水平。蔗渣培养料栽培的姬菇比稻草培养料栽培的姬菇增产 34.2 3% ,差异也达到显著水平。三种培养料栽培的姬菇 ,粗蛋白含量均高于 31% ,氨基酸总量三者相近 ,均高于 2 2 % ,E/T值达 37%左右 ,接近FAO/WHO提出的 4 0

The yield, biological efficiency, protein and amino acid contents of Pleurotus cornucopiae cultivated with the composts using Minmu No.42, bagasse and rice straw as main materials were compared and analyzed. The result showed that the biological efficiency of P.cornucopiae cultivated with Minmu No.42 compost was the highest (1.14). The variance analysis indicated that,compared with the yield of P.cornucopiae cultivated with rice straw compost and bagasse compost, the yield increment rate of P.cornucopiae cultivated with Minmu No.42 compost was 60.11% and 19.28% resp., all reached 1% and 5% significant level resp. While the yield increment rate of P.cornucopiae cultivated with bagasse compost was 34.23%, compared with that cultivated with rice straw compost, it reached 5% significant level either. And the crude protein contents of P.cornucopiae cultivated with above mentioned 3 kinds of composts were all over 31%, the total amino acid contents were all over 22%, and the E/T ratios were all around 37%, near the consult model of 40% raised by FAO/WHO.
