The invention discloses a no-tillage cultivation method for mid-season rice in a winter and spring fallow field. The method comprises the following steps: field straw is reserved after late rice is harvested, and field dry cultivation is maintained to promote weed growth in winter; in a second year, adult ducks trample the weeds twice in 5 consecutive days to form an ecological carpet prototype composed of the weeds, mud, duck manure and unrotten straw on the field surface; a skid-mounted grass-pressing plate is adopted to act on the weeds and the unrotten straw in the ecological carpet prototype to form an ecological carpet, and ecological planting holes used for sowing and ecological fertilization holes used for fertilization are formed in the ecological carpet, so that the ecological carpet is constructed to be an ecological hole carpet; under no-tillage no-irrigation conditions, sprouted rice seeds are sown in the ecological planting holes, then the ecological planting holes are covered, a fertilizer is applied into the ecological fertilization holes, and the ecological fertilization holes are covered; and on the basis of conventional field management, when the rice grows to anearly tillering period, young ducks are thrown to prevent and control diseases, pests and weeds, a compound fertilizer is applied in an active tillering period, a compound fertilizer is applied againin a booting stage, and therefore no-tillage cultivation for the mid-season rice in the winter fallow field is completed. The method provided by the invention improves a utilization rate of chemicalfertilizers, and reduces an amount of water used in a steeping field and a use amount of pesticides.
