The invention discloses a solar multifunctional tatami for rural residences, and relates to the technical field of tatami, the solar multifunctional tatami comprises a roof and a tatami, the outer surface of the upper end of the tatami is fixedly connected with a telescopic column, the outer surface of the upper end of the telescopic column is fixedly connected with a desktop, and the roof is provided with a solar tube; the tatami achieves a heat preservation effect according to hot water transmission of solar pipes, a heat preservation box, a heating pipeline, a water collector and a tatami heat preservation plate are arranged in the tatami, the heating pipes are wrapped by heating pipes, hot water generated by the solar pipes enters the heat preservation box to serve as heating water, the tatami heating plate is controlled by a switch, and a building roof adopts the solar pipes for heating. The obtained hot water heated in the solar pipe can be supplied to the indoor tatami, energy for heating work is provided, meanwhile, water resources are reasonably utilized, the consequences that a large number of non-renewable resource coal and the like need to be consumed for heating in winter, the environment is polluted, and a large number of resources are consumed are avoided, and energy conservation and environment protection are achieved.
