Method for manufacturing standard capsule for plant seed sowing depth

The invention discloses a method for manufacturing a standard capsule for plant seed sowing depth. The method comprises steps as follows: parameter design, product modeling, mold design, material mixing, putting of the mixture into a mold, compression molding, heating and airing, feeding of base fertilizer and seeds, capsule body sealing, pasting of two-dimensional codes, overall packaging. The seed capsule fully meets different soil depth standard sowing requirements of seeds, a wood bit substrate provides certain insulation and moisturizing effects, so that the seed budding rate and the survival rate of buds are increased, and the budding consistency is improved. Nitrogen, phosphorus and potassium fertilizer in a standard ratio in the substrate can provide the seeds with scientific nutrients, and the seed capsule can protect the seeds from being invaded by birds and other animals during the budding. Glutinous rice glue of the formed seed capsule is environment-friendly, breathable and permeable and can be degraded completely, rapidly and naturally, and all information and big data of the seeds and an internet entrance can be known in real time with the adoption of a two-dimensional code technology.
