Integrated bionic culture medium ion concentration online detection device and method

Abstract

The invention provides an integrated bionic culture medium ion concentration online detection device and method. The integrated bionic culture medium ion concentration online detection device comprises bionic leaves, a bionic stem, a main stem, a bionic root, an electrode unit, a water storage and drainage unit and a control unit. A communicating hole is formed in the bottom of the bionic leaf, the bionic stem is of a hollow pipeline structure, a water storage and drainage unit is arranged in the main stem, one end of the bionic stem is communicated with the communicating hole, the other end of the bionic stem is communicated with the water storage and drainage unit through the main stem, and the bionic root is arranged on the lower portion of the main stem and communicated with the waterstorage and drainage unit. The electrode unit is arranged at the bottom of the water storage and drainage unit. Moisture in the environment is collected through the bionic structure, moisture migration is accurately controlled, enough ion micro-solution is formed on the surface of the sensor electrode in the heterogeneous system, the ion concentration detection condition is met, and therefore on-line detection of the ion concentration of the culture medium is achieved.

Description

technical field [0001] The invention belongs to the technical field of agricultural cultivation information detection, and in particular relates to an integrated bionic cultivation substrate ion concentration online detection device and method. Background technique [0002] Substrate cultivation is one of the main methods of protected horticultural production. In order to adapt to the development direction of agricultural digitalization, networking and intelligence, protected horticulture puts forward requirements for the real-time collection and management of cultivation soil matrix nutrient information, so that according to the needs of plant growth, Precisely control the fertility of the soil matrix to improve the quality and efficiency of agricultural production, while reducing pollution and realizing energy saving and emission reduction. [0003] The soil matrix for cultivation is a heterogeneous system composed of various minerals, organic and inorganic particles, a ce...
