Forestry seedling cultivation and irrigation method

The invention discloses a forestry seedling cultivation and irrigation method, a plurality of placement plates are slidably arranged in a cultivation shed, a plurality of placement grooves are formed in the tops of the placement plates, and rotating mechanisms are arranged in the placement grooves, and relates to the technical field of seedling cultivation. According to the forestry seedling cultivation and irrigation method, a water-saving irrigation mechanism, a layering mechanism and a mixing mechanism are arranged between a cultivation shed and a placement plate, so that seedlings cultivated in the placement plate can be irrigated through synchronous cooperation of the water-saving irrigation mechanism, the layering mechanism and the mixing mechanism when the seedlings need to be irrigated; by means of the arrangement, seedling root system soil in the cultivation pots in the placing plates can be comprehensively irrigated, the problem that a traditional water source adopts high-position concentrated atomi
