Abstract

The invention discloses a device for measuring the multiple parameters of soil. The device comprises a hollow supporting rod, signal wires arranged inside the supporting rod, a data acquisition module and a power module arranged on the supporting rod, and moisture sensors and temperature sensors, wherein the moisture sensors and the temperature sensors are arranged alternately in the length direction of the supporting rod and connected with the data acquisition module via the signal wires; the moisture sensors are used for measuring the conductivity of the soil and the moisture content of thesoil at various depths; the temperature sensors are used for measuring the temperature of the soil at various depths and transmitting the measured moisture content, conductivity and temperature of the soil to the data acquisition module; and the data acquisition module is used for calculating the matric potential of the soil according to the received moisture content, conductivity and temperatureof the soil. Accordingly, the device provided by the invention is capable of measuring the multiple parameters of the soil and calculating the matric potential of the soil, thus detecting the conditions of the soil in a long-term, overall and effective way and providing better guidance to agricultural production.

Description

technical field [0001] The invention relates to the field of soil parameter measurement, in particular to a soil multi-parameter measurement device. Background technique [0002] For crops, soil provides important physical support for the growth and development of plants, supplies essential nutrients, water and air for plant growth, and can affect plant growth and food production by controlling soil factors. Among them, water is an important part of soil. Various nutrients in soil are absorbed by plant roots through water. The accumulation, transformation and migration of organic and inorganic substances in soil require the participation of water. Soil conductivity is a comprehensive physical parameter that reflects soil salinity and other properties. Excessive salinity in the soil will make it difficult for plants to absorb water, cause physiological drought, and even cause crops to wither and die gradually; it will also cause dysfunction in the absorption of nutrients by p...
