Abstract:: In this paper,the changes in greenhouse environment of assembled arch shed and bamboo arch shed for leek was studied by ‘Wenshi Wawa’,from the National Agricultural Information Engineering Technology Research Center.Structure of trough solar greenhouse,the internal light intensity,air temperature,air relative humidity,soil temperature and other environmental parameters were measured in extreme cold conditions in arid region of Ningxia.The results showed that the environmental parameters of the diurnal variation curve comparison could be found;two kinds of structure of arch shed in assembly leek special arch shed temperature,light intensity,soil temperature and air humidity was significantly better than the bamboo arch shed.The prefabricated arch shed in the vast areas of the Middle Arid Zone of Ningxia,Yellow River irrigation area was suitable for promotion.
