Soilless culture nutrient solution mixing device

Abstract

The invention discloses a soilless culture nutrient solution mixing device, and belongs to the technical field of soilless culture. The device structurally comprises a box body. A culture chamber is arranged at the upper portion of the box body. A plurality of stock solution storing chambers are fixed to the lower portion of the culture chamber. A feed port is formed in each stock solution storingchamber. The bottom end of each stock solution storing chamber is connected with a mixing chamber through a second pipeline. The bottom end of the culture chamber is connected with a mixing chamber through a first pipeline. The bottom end of the mixing chamber is connected with a mixed liquid storing chamber through a conveying pipeline. A filtering area, a stirring area and a plurality of filtering plates in the filtering area are sequentially arranged in the conveying pipeline. The filtering plates are arranged in the filtering area. A stirring mechanism is fixed into the stirring area. Themixed liquid storing chamber is connected with the culture chamber at the upper portion of the box body through a water pump by means of a liquid conveying pipe. The mixed liquid storing chamber is fixed to a bottom plate. A control device is arranged on the wall of the box body. Stirring can be effectively conducted without losing time, the filtering plates are used for filtering out mediums, plant roots and stems and other large-particle waste left in a nutrient solution, and diseases are avoided.

Description

technical field [0001] The invention belongs to the technical field of soilless cultivation, in particular to a soilless cultivation nutrient solution mixing device. Background technique [0002] Soilless cultivation refers to the method of fixing plants with seedling substrates and supplying nutrients with nutrient solution to cultivate plants. Soilless cultivation systems can be divided into two categories: open and closed according to whether the nutrient solution is recovered and reused. In the open soilless cultivation system, the nutrient solution is not recycled, and the excess nutrient solution is discharged into the environment after being absorbed by the crops, which will cause certain pollution to the environment, such as surface or groundwater, and soil. In the closed soilless cultivation system, the nutrient solution is collected and recycled, saving water and fertilizer, and reducing environmental pollution.

AI Technical Summary

Problems solved by technology

[0003] Nutrient solution is a new type of nutrient solution synthesized by using environmental biological ecological symbiosis technology and the principle of mycorrhizal symbiosis through biological fermentation, chemical integration and physical activation. Nutrient solution is the key to soilless cultivation, and different crops require different nutrient solution formulas At present, there are many formulas published in the world, but they are similar, because the original formula is originally derived from the chemical composition analysis of the soil extract. Among the nutrient solution formulas, the biggest difference is the ratio of nitrogen and potassium. The plant nutrient solution is generally multi-component. Compound nutrition, in the form of water, the concentration is not as high as that of solid fertilizers, and it has less impurities, which is easy for plants to absorb. Generally, the nutrient solution is used every 7 to 10 times and 3 to 5 drops each time, so it is best to dilute it with water in proportion and then apply it to the leaves. Spraying, as soilless cultivation requires more and more nutrient solutions, the nutrient solution cannot be used directly, it needs to be mixed evenly, and there is no ideal mixing device at present

[0004] In order to reduce the pollution caused by the discharge of nutrient solution to the environment, the soilless cultivation system at home and abroad is gradually changing from open to closed. Chance of Exposure to Pathogens

Therefore, root-borne diseases are more likely to occur in closed systems, and they spread rapidly, such as cucumber wilt, cruciferous soft rot, and tomato wilt.
