为了提高段木栽培黑木耳的接种效率,减轻劳动强度,提高接种成活率,陕西省宁陕县农机研究所、农机修造厂,接受地区和县科委下达的研制耳棒钻孔机的任务。经过两年多的试制改进,终于研制成功了6EK-310型菌棒钻孔机,并于1982年通过了鉴定。该机系三头高速台钻,利用钻头切削成 In order to improve the efficiency of vaccination of black fungus in segment wood cultivation, reduce the labor intensity and increase the survival rate of inoculation, the task of developing earbud drilling machine issued by Ningshan County Agricultural Machinery Research Institute of Shaanxi Province and farm machinery repair factory was accepted. After more than two years trial improvement, finally developed a successful 6EK-310 bacteria stick drill, and in 1982 passed the appraisal. The machine is three high-speed bench drill, the use of bit cutting into
