Design of Rice Factory Three-dimensional Carpet Raising Seedlings System Engineering

The factory raising seedlings is a large-scale concentrated raising seedlings method, which is often used to develop seedlings of rice, vegetable and flowers. The technology and application of factory raising seedlings were introduced in this paper. Three kinds of raising seedlings modes, which have been put in use in China, are small raising seedlings greenhouse, intelligent raising seedlings greenhouse and factory raising seedlings respectively. The disadvantages are that, they belong to tray raising seedlings mode which needs large fields and trays, and the labor intensity is too hard. In order to reduce the area and raise the level of raising seedlings mechanization, a kind of rice factory three-dimensional raising seedlings system was presented, which is consisted of greenhouse, seedlings frame, carpet seeder and so on. A new carpet raising seedlings was also put forward and can produce long seedlings carpet that is twice as wide as seedlings tray at least. And a carpet seeder designed can flat the nutritional tape into seedlings frame and put seeds and topsoil on the tape. Integrating with multiple stratifications, carpet raising seedlings and intelligent control technology, the factory three-dimensional carpet raising seedlings system provides technical support for the seedlings industrialization development in future.
