Aeroponic culture device with root core electrode

Abstract

The invention provides an aeroponic culture device with a root core electrode. The device comprises a planting groove, electrodes, an electrostatic spray device, a detection mechanism and a controller, wherein the planting groove comprises a planting plate, and a plurality of planting rings are arranged on the planting plate; the electrodes are arranged in the planting rings on the planting plate;the nozzle of the electrostatic spray device is positioned under the planting plate, and charges carrying in spray generated by the electrostatic spray device are unlike those generated by the electrodes; the detection mechanism comprises a humidity sensor which is used for detecting the humidity in the planting groove; the controller is respectively connected with the electrodes, the electrostatic spray device and the detection mechanism. According to the aeroponic culture device, after the electrodes arranged in the planting rings are electrified, droplets carrying unlike charges around theroot part of a plant are attracted by the charges of the root core part and reach the root core, so that the phenomenon that aeroponic cultured crops have an abnormally developed root system, droplets are difficult to reach the root core part, and have a 'wet-outside dry-inside' root system can be radically solved, and the aeroponic culture efficiency can be improved.

Description

technical field

[0001] The invention belongs to the field of agricultural engineering research, and in particular relates to an atomization cultivation device with a root core electrode. Background technique

[0002] Aerosol cultivation, referred to as fog cultivation, is a new soilless cultivation mode that meets the water and fertilizer needs of plant roots in the form of atomized nutrient solution. Compared with traditional soil cultivation and ordinary hydroponics, plant roots are directly exposed to water filled with atomized nutrients The air is the best cultivation mode to solve the contradiction between water and air in the root system of plants. During aeroponic cultivation, because the root system of the aeroponic crops is extremely developed, it is difficult for the mist to reach the core of the root system, and the phenomenon of "wet on the outside and dry on the inside" of the root system occurs, which reduces the efficiency of aeroponic cultivation, and may cau...
