This invention provides a method for planting multiple crops of fast-growing crops per year with alternating periods of vigorous growth and seedling stage. The method includes soil improvement in the planting area to ensure that the organic matter content in the soil is greater than or equal to a preset value, eliminating the need for tilling for two years; dividing the planting area into a first zone and a second zone, with a wheeled or tracked path between them; inhibiting crop growth in the first or second zone to alternate between vigorous growth and seedling stage crops; and applying fertilizer to the first or second zone, specifically in the following situations: applying fertilizer to the first or second zone after harvest; and / or applying fertilizer to the first or second zone during the seedling stage. This invention achieves alternating periods of vigorous growth and seedling stage crops on the same land by inhibiting crop growth in the first or second zone, thereby improving sunlight utilization. Furthermore, the wheeled or tracked path prevents damage to the root system during the vigorous growth or seedling stage.
