银合欢木屑栽培香菇的配套技术

The comprehensive techniques of growing Lentinus edodes with sawdust of Leucaena leucocephala

研究了银合欢木屑的营养成分及利用其栽培香菇的技术措施 ,并筛选了适用优质香菇菌株和高效益栽培方式。试验结果 :1可用银合欢木屑替代 50 %麸皮 ,既降低原料成本 ,又使感染率降低 11.8个百分点 ,鲜菇产量提高 5.1%。 2选用高产香菇菌株 785,可比其他 4个菌株增产鲜菇 14.8%以上。 3 (短 )袋栽培比用菌筒或菌块栽培法增产 ,而且可以减少高温制种感染率高的危害。 4与红栲木屑栽培相比 ,银合欢木屑栽培可增产鲜菇 52 .4 % ,生物效率提高 2 6.7个百分点。该技术措施适合于在高温低海拔地区应用 ,具有省工本、抗感染、高产和高效益等优点 ,在闽南地区示范应用推广 ,增产鲜菇 55.6% ,生物效率提高 2 5.

The nutritive composition in sawdust of Leucaena leucocephala and its culture practices in growing Shiitake( Lentinus edodes )were studied The optimal medium composition,high\|yielding and excellent\|quality strains and culture patterns were showed as follows:①The sawdust of L leucocephala were used as nitrogenous additives to subsitute 50% of wheat bran,and the cost was lower,the infection rate reduced by 11 8% and the yield of shiitake increased by 5 1%.②Strain 785 was better than other 4 strains for the sawdust culture,and the yield of shiitake increased by 14 76%～69 5%.③Using the small plastic bags to hold the sawdust instead of making the sawdust into rolls reduced the damage caused by the infected strains cultivated during hot days.④Compared with the cultivation using the sawdust of Castanopsis hystrix, the yield of shiitake increased by 53 6% and biological efficiency increased by 26 7%.The techniques are suitable to lower altitudes with high temperature They have many advantages,such as saving labour and cost,resistance to infected strains and high\|yielding with excellent economic returns Using the techiques will increase yield of shiitake by 55 6% and biological efficiency by 26 7%
