目前,我县平菇生产发展很快。为了提高生物效率,降低生产成本,我们探索了地沟双膜冬栽平菇,收到了较好效果。如1988年投棉籽壳料2500公斤,产鲜平菇4100多公斤,生物效率达164%,比常规袋式栽培提高60%左右。现将主要技术措施简介如下:(一)选地与地沟建造:选背风向阳场地,按东西走向挖沟。沟深180厘米、宽150—200厘米,长以30米左右为宜,南北墙分别高出地面20和40厘米,东西两头留出入口和通气口;出入口要低,通气口要高,使沟底成一个自然坡度。在距沟顶下15—20厘米处按东西方向拉一与沟长相等的铁丝,上铺薄膜与沟顶平行;沟顶用竹杆搭棚架,再覆薄膜和草帘。这种地沟
At present, my county mushroom production has developed rapidly. In order to improve the biological efficiency and reduce the production cost, we explored the ditch double film winter planted mushrooms, received good results. Such as the 1988 cast cotton seed hull 2500 kg, producing more than 4100 kg of mushrooms, biological efficiency of 164%, than conventional bag cultivation increased by 60%. Now the main technical measures are summarized as follows: (A) the election and construction of ditches: lee sunny ground election, according to something to dig ditch. Ditch 180 cm deep, 150-200 cm wide, about 30 meters long is appropriate, north and south walls were 20 and 40 cm above the ground, leaving the two things east and west entrances and vents; entrances and exits to be low, vent to high, so that the ditch Become a natural slope. At a distance of 15-20 cm from the top of the ditch, a wire of the same length as the ditch should be pulled in the east-west direction. The top film should be parallel to the top of the ditch. The top of the ditch shall be scaffolded with bamboo poles and covered with film and straw curtain. This trench
