How to Print-Seed Rice: Printed Seeding Technology for Rice

The traditional rice cultivation method is to first sow pre-germinated seeds in a seedling nursery, and after the seedlings grow, transplant them into the paddy field. This not only makes it difficult to further increase the survival rate, but also involves high labor intensity for farmers and low planting efficiency. With the development of the rural economy, more and more rural labor will move to cities and towns, and crop cultivation will gradually transition to simplified, light-labor cultivation. As rice is the most important food crop in China, the development and research of direct seeding technology will have very important practical significance.

(1) Spread the straw pulp paper out on the workbench:

(2) Brush the adhesive onto the paper according to the set plant spacing and row spacing; the adhesive is rice paste. The specific brushing method is: place a plastic board frame flat on the paper; the plastic board of the plastic board frame has multiple small holes punched according to the set plant spacing and row spacing; use a brush dipped in rice paste to evenly brush across the surface of the plastic board, so that the rice paste passes through the small holes and sticks to the paper, thereby adhering the seeds:

(3) Place the rice seeds at one end of the paper obtained in step (2), and roll this end of the paper on which the rice seeds are placed. As the paper rolls, the rice seeds are evenly adhered to the paper, resulting in a roll-shaped seed paper:

(4) Lay the above roll-shaped seed paper flat in the plowed and leveled paddy field; the straw pulp paper decomposes quickly upon contact with water and will not affect seed germination. Through observation, the seedling formation rate reached 97%.
