The invention discloses a rainwater-collecting and water-saving type device for slowly releasing solid waste organic fertilizer nutriments and a method. The device comprises a trapezoidal cylinder body and a base which are integrally connected; vertical holes are formed in the cylinder body; adjusting holes in the same line are respectively formed in the cylinder body and the base; the base is provided with bulges and grooves both having wrinkles. A tree trunk base part in barren and arid hillside woodland is annularly sleeved by the device by the adjusting holes of the device, and the solid waste organic fertilizer is arranged in the device. Through the method, moisture and fertilizer nutriments are slowly released in the woodland, and the utilization rate of both the fertilizer nutriments and the moisture is increased; meanwhile, solid waste is prevented from being directly applied to soil to avoid secondary pollution risk of harmful substances such as heavy metal. According to the method ...
