银合欢叶代麸皮栽培金针菇的研究

Application of Leucaena leucocephala Leaves Instead of Wheat Bran in Cultivation of Flammulina velutipes

采用占基质总量１０％、１３．５％、１７％、２７％的银合欢叶代替基质中部分或全部麸皮作氮源，选用金针菇菌株１９、３０６、９８进行栽培试验，结果表明，采用上述四种基质栽培金针菇，菌丝长势良好，日长速均快于对照（添加２７％铁皮），增长４．０％～１８．０％，其中添加１０％银合欢叶、１７％麸皮的基质，菌丝长速最快，出菇最早，产量最高，比对照增产３．４％～５．０％。菌株１９增产最多，其次为菌株３０６。

The leaves of Leucaena leucocphala were used as nitrogenous additive instead of part or the whole of wheat bran，making up 10％,13.5％,17％and 27％,respectively,of the total media, Strain 19,strain 306 and strain 98 of Flammulina velutlpeswere selected for cultural experiment.The results showed that the hyphae of Flalnmuli-na veluties grew well in the above four media,The daily growth rate was higher thanthat of the control(added with 27％wheat bran),increasing 4.0％～18.0％. The hyphaegrew the fastest when the medium was added with 10％Leucaena leucocephala leavesand 17％wheat bran;the mushrooms brought into crop the earliest with the highestvield，increasing more 3.4％～5.0％mushrooms than the control.The strain 19 yieldedthe most and strain 306 the second.
