The invention discloses a method for intercropping and cultivating flos rosae rugosae and edible fungi. The method includes steps of (1), preparing edible fungus culture materials; (2), carrying out double-row intercropping among rows of flos rosae rugosae older than 4 years; (3), separately sowing seeds on two layers by the aid of layer sowing processes; (4), firstly, immediately covering material surfaces with plastic films after the seeds are sown, covering the films with soil and preventing the internal temperatures of land pieces from being higher than 28 DEG C under the control, secondly, immediately uncovering the films after small fruiting bodies appear, erecting small plastic arch sheds, covering the small plastic arch sheds with grass curtains, opening two ends of each film for ventilation for 10 min at noon on a daily basis and spraying water to keep moist, thirdly, harvesting primarily germinated mushrooms, culturing secondary mushrooms and carrying out other management measures identical to management measures at fruiting phases. The method for intercropping and cultivating the flos rosae rugosae and the edible fungi has the advantages that pleurotus ostreatus and pleurotus pulmonarius are intercropped among the rows of flos rosae rugosae by the aid of shallow-land-piece cultivation processes, natural shading effects can be realized by the flos rosae rugosae, and the method is low in cost and high in benefit; organic fertilizers further can be provided for the flos rosae rugosae, and virtuous cycle can be formed; lands can be reasonably utilized, and accordingly the utilization rate of the lands can be increased.
