【中文摘要】 选用 2 0种配方进行猴头菌的栽培试验。培养料配方为棉籽壳、木屑和麦麸 ,其含N量为 0 .2 2 %～ 1.4 2 %。试验结果表明 ,猴头菌子实体干物质绝对生物学效率 (ABE %=y1)、经济效益 ( y2 )与培养料含N量 (N %=x1)之间的动态关系符合Logistic方程 :y1=10 .0 0 / ( 1+3.4 2 4 2e- 2 .32 15x1) ,r′y1x1=- 0 .8648 ,P >0 .0 1;y2 =3.0 0 / ( 1+8.6791e- 2 .954 9x1) ,r′y2 x1=- 0 .8568 ,P >0 .0 1。y1、y2 与x1的相关性极显著。配方中培养料最佳含N量为 1.0 0 %～ 1.2 0 %,虽然成本较高 ,但产量最高 ,经济效益最好
【英文摘要】 compost formulae were used for the cultivation of Hericium erinaceus.The compost formulae were consisted of cotton seed hull, sawdust and wheat bran. Their nitrogen content was about 0.22%～1.42%. The results of the experiments showed that the dynamic relation between the yield (absolute biological efficiency of dry fruitbody=ABE%,y 1), the economic benefits (y 2) and the nitrogen content(N%=x 1) of the compost conformed to the logistic equation:y 1=10.00/(1+3.4242 e -2.3215x 1 ), r′ y 1x 1 =-0.8648 ** ,P>0.01; y 2=3.00/(1+8.6791e -2.9549x 1 ),r′ y 2x 1 =-0.8568 ** , P>0.01. And it was proved that the relativity between y 1, y 2 and x 1 was extremely significant, and that the optimum N content in the compost formulae was 1.00%～1.20%. The production cost of this formula was higher than others, but the yield of the fruitbody was the highest and the economic benefit was the best.
