Method for cultivating saline-alkali plant suaeda glauca under plant factory condition

The invention discloses a method for cultivating saline-alkali plant suaeda glauca under plant factory conditions, which comprises the following steps of: putting pretreated seeds into seedling cotton, putting the seeds into a seedling tray, culturing in a shading manner, adding a seedling nutrient solution after the seeds germinate, and transferring to a place with sufficient light for seedling culture, thereby obtaining the saline-alkali plant suaeda glauca. After seedling roots are exposed out of the seedling growing cotton, the seedlings are transplanted to a planting plate of a plant factory, a nutrient solution is adopted for water culture, an LED lamp with a specific wavelength proportion serves as a light source for culture, and suaeda glauca can be harvested after 35-50 days. The cultivation method provided by the invention gets rid of the limitation of the growth of the saline-alkali plant suaeda glauca on the conditions of soil fertility, temperature, illumination, salinity and the like, the yield
