银合欢木屑栽培香菇的配套技术

分析了银合欢木屑的营养成分,研制了最适宜的培养基,选用了高产优质的香菇菌株和高效益的栽培方式。发现银合欢木屑作为氮素添加物可替代50％麸皮,降低原料成本,使感染率降低11.8％,鲜菇产量增加5.1％;高产香菇菌株785比其他4个菌株至少可增产鲜菇14.8％;短袋栽培比菌筒或菌砖栽培增产,而且可以减少高温制种感染率高的危害;与红栲木屑栽培香菇相比,银合欢木屑增产鲜菇53.6％,生物学效率提高26.7％。该技术措施适合于在高温低海拔地区应用,在闽南地区增产鲜菇55.6％,生物效率提高25.8％。

Comprehensive Technique in the Cultivation of Shiitake with Leucaena leucocephala Sawdust

The nutritive compositions of Leucaena leucocephala sawdust and its application in the cultivation of shiitake (Lentinula edodes) were studied. The optimal compost composition, the high-quality strains and the cultivation methods were also studied . The L. Leucocephala sawdust was used as nitrogen additives instead of 50% wheat bran, resulting in the reduction of infection rate by 11. 8% and the increment of the shiitake yield by 5.1%. The yield of shiitake 785 increased by 14.8% than that of the other 4 strains cultivated with sawdust compost; while the yield of shiitake cultivated with sawdust put in short bag was higher than that cultivated with sawdust put in compost - tube or made into compost - brick, and the infection rate reduced compared with the spawns produceed at high temperature. Comparing with the treatment using Cas-tanopsis hystrix sawdust as compost, the yield of shiitake cultivated with L. leucocephala sawdust increased by 53.6% while the biological efficiency increased by 26.7%.
