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.
