A kind of preparation method of energy-saving and environment-friendly hydroponic vegetable planting nutrient solution

Abstract

The invention discloses a method for preparing an energy-saving and environment-friendly hydroponic vegetable planting nutrient solution, which belongs to the field of nutrient solution preparation. The solution realizes that a motor drives a fixed cylinder and an extruding cylinder to rotate, causes the carbon dioxide aqueous solution to shake, and promotes the overflow of carbon dioxide gas to the telescopic soft In the tube, make it extend to drive the extrusion plate to squeeze the heavy metal capture liquid for ejection, and cooperate with the rotation of the fixed cylinder to fully mix it with water, realize chemical reaction with various heavy metal ions, and quickly produce flocculent precipitation. At the same time, the heat generated by the operation of the motor is conducted to the memory toggle bar, making it heated and straightened, and after being straightened, the insulating capsule is extruded to deform it, which promotes the dispersion of the insulating powder, and the cold air emitted by the cooling block is transmitted to the extrusion. Toggle the bar to deform it again to restore the original state, and then deform and straighten it again by heating, so as to realize the deformation while rotating, and toggle the heavy metal capture liquid to fully react with the heavy metal ions, so that it precipitates quickly and enhances the purification effect.

Description

technical field [0001] The invention relates to the field of nutrient solution preparation, and more particularly, to a preparation method of an energy-saving and environment-friendly hydroponic vegetable planting nutrient solution. Background technique [0002] Soilless cultivation refers to the cultivation method in which water, peat or forest humus, vermiculite and other media are used as the substrate for plant roots to fix plants, and the plant roots can directly contact the nutrient solution. Hydroponics refers to the direct contact between plant roots and nutrient solution. The cultivation method without substrate does not need to be attached to the quality of the soil, and the nutrient solution is used in a container, which can be recycled and will not flow into the soil to cause pollution to the environment, and there are many types of hydroponic nutrient solutions. , There are culture solutions for different growth stages of plants, as well as nutrient solutions fo...

Problems solved by technology

[0003] In the prior art, when the nutrient solution is prepared, the water quality requirements play a role that cannot be ignored. At present, in some areas, groundwater, reservoir water, river water and other water sources contain toxic substances such as heavy metals, which is not conducive to the preparation of the nutrient solution and affects vegetable cultivation.
