example 1

[0020] Example 1: Preparation and disinfection of soilless vegetable greenhouse nutrient solution by using oxidation potential According to the calculation of various nutrient elements required for vegetable cultivation in greenhouses, it is determined that the content of various elements in the formula is 2442 mg / L, so 1 ton of nutrient solution is prepared. A total of 2.442kg of various elemental compounds is required. To prepare 1 ton of nutrient solution, according to the ratio of 1:300, about 996.7 liters of soft water and about 3.3 liters of oxidation potential water are required. After diluting the above nutrients with soft water, they are mixed with oxidation potential water and injected into the nutrient solution pool.

[0021] The prepared nutrient solution is supplied, collected and circulated to the vegetables grown in the greenhouse according to conventional supply equipment. During the working process, if the controller 7 detects that the pH value of the nutrien...

Abstract

The invention provides a system device and a method for conducting sterilization and disinfection on nutrient solution of soilless culture through the application of electrolyzed oxidizing water. According to the invention, the electrolyzed oxidizing water of a certain proportion is injected into the nutrient solution of the soilless culture to conduct disinfection on the nutrient solution. The system device comprises an electrolyzed oxidizing water preparation device, an electrolyzed oxidizing water output device, an electrolyzer input device, an automatic detection device and a controlling device. The electrolyzed oxidizing water is adopted to replace disinfection manners of high temperature disinfection, ultraviolet ray disinfection, oxidant disinfection and the like in conventional use, and has no influence and residue for plant growth, no pollution for the environment, and low cost.

Description

technical field [0001] The invention relates to the disinfection of a soilless culture nutrient solution to prevent various diseases in a soilless culture system, and mainly belongs to the field of disease prevention of agricultural planting. Background technique [0002] Since its inception, soilless culture technology has been rapidly popularized and applied in vegetable facility cultivation at home and abroad. Soilless cultivation technology can not only save arable land, but also has the incomparable advantages of conventional soil cultivation in overcoming the obstacles of continuous cropping of crops, resisting the adverse external environment, and producing pollution-free vegetables. Therefore, the scale of application of soilless culture technology has gradually expanded, and the degree of automation has become higher and higher. However, the core of soilless culture lies in the preparation and management of nutrient solution. The recycling of nutrient solution inev...
