Zusammenfassung:The present disclosure provides preparation and use of a seedling-strengthening agent added fertilizer solution-impregnated base fabric for rice mechanical transplanting and seedling raising in tray, and belongs to the technical field of rice seedling raising. The preparation and use include the following steps: (1) preparation of a hemp fiber base fabric for seedling raising; (2) preparation of a seedling-strengthening agent-added fertilizer solution; and (3) impregnation of the base fabric for seedling raising. The present disclosure solves the problems that difficulty in uniform mixing of guest soil with a seedling-strengthening agent and a fertilizer affects the growth of rice seedlings and the speed and quality of mechanical transplanting and that the subsoil, the seedling-strengthening agent and the fertilizer are lost from the bottom holes in the tray. The twisting force of rice seedling roots is increased by 30%; the consumption amounts of rice-seedling soil and seed grains are reduced by 30%, respectively; labor employment is reduced by more than 50%, and the labor intensity is substantially reduced; each base fabric costs only about RMB 0.15 yuan; thus, the base fabric features low cost for rice seedling raising, excellent quality of rice seedlings, excellent mechanical transplanting quality, and high yield.
