Abstract

The invention relates to an airborne walking type composite sensor for synchronous real-time measurement of soil compaction and moisture content, comprising a main arm beam, a rear arm beam and a cone fixed on the main arm beam; a blade bracket is vertically fixed on the main arm beam, and the main The arm beam vertically fixes the movable bracket through the movable fulcrum, a chain is fixed on the movable bracket, and a pressure sensor is fixed between the branch chain and the rear arm beam, and the signal of the pressure sensor is output to the signal processor; there is a blade at the front under the blade bracket, The cone is vertically and fixedly connected to the bottom of the movable support, and a moisture probe is compounded on the cone, and its output forms two standard 0-5V voltage signals after passing through the signal processor; respectively representing the compaction degree and the moisture content value.

Description

technical field [0001] The invention relates to a soil moisture measurement and pressure measurement technology, in particular to an airborne walking composite sensor for synchronous and real-time measurement of soil moisture and compaction degree Background technique [0002] In the process of agricultural production, soil not only provides physical support for plant growth, but also serves as a nutrient bank for plant growth. A large number of research results have shown that soil moisture content and compaction are two crucial physical parameters that affect the growth of crops. Water is the lifeblood to ensure the growth of crops. A series of reactions in the soil, energy and material exchange are all related to water, which is directly related to crop yield and quality. Soil compaction is not only closely related to the germination rate of seeds and root development of plants, but also directly affects the migration process of soil moisture. Since TOPP et al. (1980) a...
