With the economic development and agricultural structure adjustment, the rural labor force is transferring from farms to cities, and the aging of the population is appearing, so the factory raising seedlings technology will be one of the most important ways in advancing the process of cultivation mechanization, especially the development of rice factory raising seedlings in China, in which the cultivated land resources are less and less. Integrated with multiple stratification, carpet raising seedlings, and intelligent control technology, a kind of new factory three-dimensional carpet raising seedlings system was designed ,which applies carpet raising seedlings instead of tray raising seedlings and nutritional tape instead of subsoil, it can save the cost of production and reduce the consumption of the soil resources. Using multiple stratification seedlings technology instead of traditional single layer seedlings on the ground improves the land utilization efficiency. Fully mechanized operations reduce the labor intensity, and it also establishes a solid foundation for the rapid developing of seedlings industrialization in the future.
