Problems solved by technology
It is difficult to accurately control the water and nutrients in the substrate of each container because it is difficult to control the amount of nutrient solution and irrigation in the pot test. Not only is the test management difficult, the test error is difficult to eliminate, and the observation of the root system at any time is also difficult to achieve.
[0003] Hydroponic experiments can accurately control the concentration of nutrient solution, but the root system must have a relatively sufficient oxygen supply, that is, it is necessary to change the water frequently, or keep the nutrient solution in a circulating state, or continuously add oxygen (add air) to the nutrient solution.

The invention relates to a stereoscopic automatic control plant aerial fog culture apparatus with a novel nutrient solution supply system. The nutrient solution supply system comprises a nutrient solution storage container, pressurization equipment, a nutrient solution atomization spray nozzle, a nutrient solution conveying pipe and a flow division and mixing prevention device; and the nutrient solution atomization spray nozzle is communicated with the nutrient solution storage container by the pressurization equipment and the nutrient solution conveying pipe. According to the invention, the automatic control atomization supply of plant nutrient solution can be implemented; the accurate control on the concentration of the nutrient solution can be implemented; the relative consistency of growing environments of tested plants is ensured; test errors are reduced; and the temperature environment suitable for a plant root space can also be ensured. The advantages of the stereoscopic automatic control plant aerial fog culture apparatus can be summed up as follows: the stereoscopic automatic control plant aerial fog culture apparatus is automatically controlled and is convenient to manage; and the error of the atomization nutrient supply is reduced.
Description
technical field [0001] The patent of the present invention relates to scientific experiment equipment, and relates to a plant research equipment, in particular to equipment for plant planting experiments, which are applied in the fields of botany, agronomy, forestry and other related plant research and teaching. Background technique [0002] Plant nutrition research is an important part of plant physiology research and cultivation technology research and development, and potted or hydroponic methods are often used to cultivate test plants. It is difficult to accurately control the water and nutrients in the substrate of each container because it is difficult to control the amount of nutrient solution irrigation and irrigation in pot experiments. Not only is it difficult to manage the experiment, it is difficult to eliminate experimental errors, and it is also difficult to observe the condition of the root system at any time. [0003] Hydroponic experiments can accurately con...
