The invention discloses a paddy rice matrix half-water sprout cultivation method, and the method comprises the steps of using a muddy sprout cultivation seedbed that has a modern agriculture rainproof, insulating or sunshade facility; employing a sprout cultivation plated matrix for sprout cultivation; maintaining the matrix moistening; disposing the sprout cultivation plate in the muddy sprout cultivation seedbed; and keeping no irrigation in the sprout cultivation seedbed surface in the whole sprout cultivation process. The detail method comprises the steps of A preparing the sprout cultivation seedbed; B matching the matrix; C preparing a sprout cultivation apparatus and related apparatuses; F packaging the matrix in plates, disinfecting and sowing in a seeder streamline; G accelerating germination; H cultivating a matrix half-water sprout cultivation seedbed; and I managing cultivation. The method solves the problems of both water sprout cultivation and dry sprout cultivation; at the same time, the technical problems of sprout cultivation in a factory is solved; growth and management in southern paddy rice sprout cultivation is benefited; mechanical transplanting requirement like high and uniform seedling density, of the cultivated seedling, vigorous sprout, good root junction, light weight and convenient transportation are realized.
