In a greenhouses of the factory-type seedling center in Jiangxi Province, a printed seeding and raising technology’s been introduced. The technology involves putting rice seeds into a printing sower that can be positioned precisely, laying a special bamboo charcoal fiber seedling sheet on it, applying edible glue to the roller fixing holes, and then fixing the seeds to the sheet with a roller. Finally, the sheet is rolled up into a tube, completing the seed “printing” process. The seedling sheet with the “printed” seeds can be stored in a rolled up state and stored for long periods of time, and can be taken out and grown when needed, making it possible to adjust the sowing time and disperse the work period.

In a nearby plastic greenhouse, seedling sheets with “printed” rice seeds were spread out in an orderly fashion and laid on top of nutrient-rich soil. The seedling sheets were then covered with culture soil and moderately watered to ensure that the seeds absorbed sufficient nutrients and sprouted smoothly. It took only a dozen days from sowing to transplanting.

The newly introduced “printed seedling technology” allows the sowing amount to be digitally controlled, so one printing sowing machine can complete the seedling work of 400 mu (about 26.7 hectares) of rice paddies in eight hours. This technology solves the problems of uneven seeding, large amount of seed use, and variable seedling quality in traditional sowing, effectively saving time and labor costs in late rice seedling cultivation, reducing the cost and improving the efficiency of agricultural production.
