商都县地处乌盟后山地区,气候严寒,无霜期短(100～110天),为了解决小麦、莜麦育种的就地加代繁殖问题,去年我们采用了塑料薄膜温室冬播繁殖,初步获得成功。试验用的温室,采用北京改良式加热温室,土木结构,砖墙(北墙为空心墙),东西长6米,南北深5米,总面积30平方米,栽培床18平方米,利用率60％。栽培床下面40厘米用砖砌成炕洞式的冻土隔离层,以保证有和室温相应的土温。采光窗用塑料薄膜,其他如复盖、加温设备等同于一般温室。从
Shangdu County is located in the mountainous area of Ujwamun with cold climate and short frost-free period (100-110 days). In order to solve the problem of on-site multiplication of wheat and oatmeal breeding in winter, we adopted the winter sowing of plastic film greenhouses and achieved initial success . The greenhouses used in the experiment are Beijing modified heating greenhouses, civil engineering structures and brick walls (with a hollow wall on the north wall), 6 meters long from east to west and 5 meters deep from north to south with a total area of 30 square meters and a cultivation bed of 18 square meters with a utilization rate of 60 %. 40 cm below the cultivation bed made of brick clay karst permafrost insulation to ensure that there is room temperature and the corresponding soil temperature. Light window with plastic film, other such as cover, heating equipment equivalent to the general greenhouse. From
