Abstract: The factory seedling-nursery for rice seedlings in throw-spreading is a new method in rice cultivation and production. This new method is a large reform of traditional rice production: It is not necessary to use seedling nursing land;it is not necessary to transplant the seedlings into rice field;in spreading seedlings, there is no regular spacing and rows;all seedlings are prepared and nursed in factory and greenhouse. This is a method to promote mechanization for rice seedling, planting and cultivation.In Iianjiao, Dali, Nanhai City of Guangdong Provincial Compprehensive Rice Mechanization Demonstration Center, a set of rice seedlings nursery in factory was built in early 1993. This factory includes: rice seedlings buds accelerating equipment and temperature controlling systems; rice-seed buds spreading line with soil;and greenhouse. Through Spring and Fall season experiments for rice seedlings nursing and field rice production, it was proved that this new method had many advantages not only on saving labor, time, seeds,and costs, but also gave high rice yield and efficiency, and that this method would give abrilliant future in rice cultivation and mechanized production.
