Vegetable aeroponic cultivation rhizosphere environment monitoring system for solar greenhouse

Abstract

The invention relates to a vegetable aeroponic cultivation rhizosphere environment monitoring system for a solar greenhouse. The vegetable aeroponic cultivation rhizosphere environment monitoring system comprises a signal acquiring device, a nutrient solution pond, at least one vegetable aeroponic cultivation rack, a nutrient solution monitoring sensor, aeroponic cultivation vegetable root system monitoring sensors and an intelligent terminal; the nutrient solution pond is arranged under the ground of an indoor environment of the solar greenhouse; the nutrient solution monitoring sensor is arranged in the nutrient solution pond, and is electrically connected with the signal acquiring device; the at least one vegetable aeroponic cultivation rack is arranged in the solar greenhouse, each aeroponic cultivation vegetable root system monitoring sensor is arranged on the corresponding vegetable aeroponic cultivation rack respectively, and the aeroponic cultivation vegetable root system monitoring sensors are electrically connected with the signal acquiring device; and the signal acquiring device is in communication connection with the intelligent terminal. According to the vegetable aeroponic cultivation rhizosphere environment monitoring system disclosed by the invention, various environmental factors of vegetable aeroponic cultivation rhizosphere are monitored, and the monitoring and controlling capability of an aeroponic cultivation environment of the solar greenhouse is improved, so that automatic production degree of vegetables of the greenhouse is improved.

Description

technical field [0001] The invention belongs to the technical field of facility agriculture, and in particular relates to a monitoring system for the root environment of fog-baked vegetables in a solar greenhouse. Background technique [0002] Soilless cultivation technology is currently one of the most effective means to solve the difficulties of soil pollution, salinization, and continuous cropping obstacles in facility production. , which deteriorates the oxygen supply of the root system and affects the growth of the plant. Therefore, the key to developing soilless cultivation technology is how to solve the contradiction between oxygen supply and liquid supply. Vapor mist cultivation is a soilless cultivation technique that uses a spray device to atomize the nutrient solution to the root system of the plant to provide the water and nutrients needed for plant growth. It is the solution to the root water-air contradiction in all soilless cultivation techniques best form. ...

AI Technical Summary

Problems solved by technology

At present, because the aeroponic system has strict requirements on nutrient solution and spray conditions, accidents such as poor management or power outages can easily cause crop growth damage or even death. In order to reduce the risk of aeroponic cultivation, it is urgent to equip an aeroponic monitoring system and improve System monitoring and management level
