Abstract

The invention relates to a seedling device of multilayer tidal irrigation in an agricultural technical field, which comprises a seedling bedstead of multilayer tidal irrigation, a nutrient solution cycle device, a fertilizer preparation device, an automatic control device, a sterilization device and an air mixer. The fertilizer preparation device is connected with the nutrient solution cycle device through a pipe and connected with the automatic control device which is used for adjusting the concentration and pH value of the nutrient solution; the nutrient solution cycle device is connected with an inlet pipe of the sterilization device through an output pipe; an outlet pipe of the sterilization device is connected with an inlet pipe of the air mixer; an outlet pipe of the air mixer is connected with the seedling bedstead of multilayer tidal irrigation which is connected with the nutrient solution cycle device. The seedling device of multilayer tidal irrigation of the invention is characterized by automatic supplemental lighting and efficient space usage, can automatically control irrigation of water and nutrient solution accurately, and is particularly suitable for green house and other environment of small space.

Description

technical field [0001] The invention relates to a seedling raising device in the field of agricultural technology, in particular to a multi-layer tidal irrigation seedling raising device. Background technique [0002] Tidal irrigation is an advanced water-saving irrigation. Using it to intelligently manage the water and nutrient solution required by plants can increase the growth rate of plants, reduce labor intensity and reduce management costs. At present, the United States, Japan, the Netherlands and other countries have a trend of widespread application, and the country has just started. [0003] After searching the literature of the prior art, it was found that the U.S. Patent: Ebb and Flood Irrigation System, whose application number is 07 / 892,240, stated as: an irrigation system, including a large number of plants placed on the ground and placed in protective containers grow container. The protective container is connected to a piping system with inlet and outlet va...
