摘要:
利用双孢蘑菇废菌渣不发酵直接连栽姬松茸,结果表明:4月15日播种的姬松茸产量为3.41 kgm-2,分别比3月15日和4月1日播种增产8.20%、3.31%;姬松茸不同营养配方平均产量差异达极显著水平,以大豆粉1.0 kg、酵母粉0.25 kg、硫酸铵0.2 kg的营养配方,菌丝生长速度最快,菌丝浓白;以大豆粉1.5 kg、酵母粉0.75 kg、硫酸铵0.2 kg的配方产量最高,平均产量达3.76 kgm-2,比对照增产9.62%;不同姬松茸菌株产量差异达极显著水平,姬松茸A5、A6菌株菌丝生长最快,日均生长速度达0.29 cm,菌丝浓白,A8菌株产量最高,平均单产为3.42 kgm-2。双孢蘑菇废菌渣不发酵直接栽培姬松茸缓解栽培双孢蘑菇、姬松茸争夺原料的矛盾,降低食用菌栽培成本,提高培养料生物转化率。
Abstract:
Agaricus Blazei Murrill was cultivated in sequential cultivation with the unfermented waste from Agaricus bisporus cultivation.The results suggested that the method was applicable.The yield of A.Blazei Murrill cultivated on April 15 was 3.41 kgm-2, which increased about 8.20% and 3.31% as compared to those cultivated on March 15 and April 1, respectively.Formulation of the culture medium significantly affected the growth vigor and color of the hypha.The medium consisting of 1.0 kg soybean powder, 0.25 kg yeast powder and 0.2 kg ammonium sulfate resulted in the fastest growing white hypha.On the other hand, the greatest yield was found with the mushrooms grown on the medium containing 1.5 kg soybean powder, 0.75 kg yeast powder and 0.2 kg ammonium sulfate, with an average of 3.76 kgm-2, which was a 9.62% increase over the control.There were significant differences on the yields among different strains of A.Blazei Murrill.For instance, A5 and A6 grew the fastest, averaging a daily growth rate of 0.29 cm; and, A8 had the highest yield of 3.42 kgm-2.This cultivation practice appeared to have a potential for wide application that could lessen the burden of competing for raw materials between A.Blazei Murrill and A.Bisporus cultivations, reduce the cost of cultivating edible fungi, improve the biological efficiency of composting and waste recylcling, and improve the profibility of the mushroom farming.
