[0029] In use, rice seeds to be sown are placed in the seed chamber 6 of the sowing unit 3, and seedling soil is placed in the covering chambers 13 of both the first covering unit 2 and the second covering unit 4. The operator places the seedling trays sequentially onto the conveyor platform 1, which then moves the trays from below through the first covering unit 2, the sowing unit 3, the second covering unit 4, and the water spraying unit 5. When the trays pass the first covering unit 2, the belt conveyor 14 of the first covering unit 2 spreads soil into the trays, forming the base soil. When the trays pass the sowing unit 3, the sowing roller 8 rotates, dropping rice seeds intermittently onto the trays, completing the sowing process. When the trays pass the second covering unit 4, the belt conveyor 14 spreads soil onto the trays, covering the rice seeds, completing the covering process. When the trays pass the water spraying unit 5, the nozzles 25 of the water spraying unit 5 spray water onto the trays, completing the watering process.
