南方冬春气温低,一般在12℃以下,平菇生长缓慢,甚至子实体还会发生冻害。因此,搭盖小拱棚予以保温,可加快其生长,缩短生产周期,提高效益。现将其技术要点简介如下:一、小拱棚的搭建选取竹(木)条或竹片,搭成高1.5～2.6米,宽1.2～3米,长随田块而定的弓形架。且每隔3～6米留一侧天窗,棚的两端各留一窗一门。竹木条弓的两边、及顶部用绳子牵拉加固,竹木条要光滑平整,以免刺破棚膜。弓架、竹木条的间隔,约是1.5～2.5米,粗的宜
South winter and spring temperatures are low, generally below 12 ℃, mushroom growth is slow, even fruiting bodies will occur frost damage. Therefore, take a small arch shed insulation, can accelerate its growth, shorten the production cycle and improve efficiency. Brief introduction of its technical points are as follows: First, the construction of small shed selection of bamboo (wood) or bamboo, take the height of 1.5 to 2.6 meters, 1.2 to 3 meters wide, long with the field of the bow frame. And every 3 to 6 meters to leave one side of the skylight, shed at both ends of each leaving a window. Bamboo bow on both sides of the bow, and the top rope reinforcement, bamboo strips should be smooth and flat, so as not to puncture the film. Bow stand, the spacing of bamboo, about 1.5 to 2.5 meters, coarse should
