烟炕房是烟叶产区用来烤烟叶的场所,每年冬春季都闲置着、为了提高烟坑房利用率,笔者于1989年利用坑房进行生料栽培金针菇试验。每座栽培面积约30平方米,投棉籽壳400公斤,除去成本纯收入750元以上。生料栽培可收3～4潮菇,整个生产周期3～4个月。生物效率一般都在90%以上。最高达150％。现将主要技术介绍如下:
Tobacco kang room is the tobacco producing areas used to flue-cured tobacco leaves every year in winter and spring are idle, in order to improve the smoke pit room utilization, the author in 1989 using raw materials for cultivation of flax mushroom experiment. Each cultivated area of about 30 square meters, cotton seed hulls cast 400 kg, net cost of removal of more than 750 yuan. Raw material cultivation can receive 3 to 4 tidal mushrooms, the entire production cycle of 3 to 4 months. Biological efficiency are generally more than 90%. Up to 150%. The main technical introduction is as follows:
