Abstract Gobi desert is characterized by severe water leakage, high surface temperature and strong evaporation. A set of solar-based pipeline equipment for culturing vegetables of sand culture is assembled, including a photovoltaic power generation system, a pipeline system for vegetables of sand culture and an automatic control system. The photovoltaic power drive pump ensures the regular liquid feed and back flow of the culture system. On the basis of comparing the cucumber, tomato and water melon in such a way and those planted in the field, this paper measures the chlorophyll fluorescence parameters, tests the individual plant characteristics, and makes a comparative study on anatomical structure of stems. The results show that, compared with those planted in normal way, the vegetables cultured with the solar-based pipeline equipment have higher original photosynthetic transformation efficiency of photosynthesis system Ⅱ (PSⅡ), more dwarf individual and stronger stems; The marrow and vascular bundle developed and the cortical layer thickness increases. These features show that the equipment is suitable for vegetable culture in Gobi desert and has development and application prospect.
