黑木耳人工栽培在吉林已有多年,但在生产过程中,多用大径木做耳材。在产量上,周期平均每立方米的单产仅有5kg左右。严重影响生产者的经济收益和森林资源综合利用效益。为了充分利用林区的小径木(枝丫梢头),达到节省木材,合理利用木材,降低成本,提高效益.我们于1983—1987年在松花湖实验林场用小径木进行黑木耳栽培试验,取得了周期平均每立方米耳木产量达11.5kg的高产。经过近几年在全地区推广,获得了令人满意的效果。小径术做耳材,它的特点是,投资少、产量高、出耳早、产量集中在当年和2年生、周期短、见效快、成本低、管理方便、能节省大量木材。
Cultivation of black fungus in Jilin for many years, but in the production process, the use of large diameter wood ear materials. In terms of output, the average yield per cubic meter is only about 5 kg per cycle. Seriously affecting the economic benefits of producers and the comprehensive utilization of forest resources. In order to make full use of the woods in the forest area, the wood is saved, the wood is used rationally, the cost is reduced and the benefit is improved.We conducted the black fungus cultivation experiment with small-diameter wood in Songhua Lake Experimental Forest Farm from 1983 to 1987, An average yield of 11.5kg per cubic meter of earmuffs. After several years of promotion in the whole region, it has achieved satisfactory results. Small diameter surgery ear materials, which is characterized by less investment, high output, ear early, the output concentrated in the current year and 2 years, short cycle, quick, low cost, easy management, can save a lot of wood.
