Multi-layer tide irrigation raise seedling device

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...

AI Technical Summary

Problems solved by technology

The invention has a reasonable design, can save water resources, does not pollute the surrounding environment, and is conducive to commercial planting of plants, but there are also some problems: (a) only one layer of space can be used; (b) it is not suitable for use in some small environments (such as semi-closed and airtight environment); (c) due to the protection of the opening on the top of the container, placed on the ground, it is easily affected by the external environment, such as rain, etc., which will affect the precise irrigation of water and nutrient solution
