Description

technical field [0001] The invention relates to the field of soil detection, in particular to a detection device for soil components and a detection method thereof. Background technique [0002] Soil is the main body of nature composed of layers of mineral components with different thicknesses. The difference between soil and parent material lies in its shape, physical properties, chemical properties, and mineralogy properties. Due to the interaction of the earth's crust, water vapor, atmosphere and biosphere, the soil layer is different from the parent material layer. The rocks on the earth's surface are gradually broken into loose mineral particles of different sizes after weathering. , while soil is formed and evolved under the comprehensive action of various soil-forming factors such as parent material, climate, organisms, topography, and time. The composition of the soil is very complex. Generally speaking, it is composed of three phases of solid, liquid and gas such a...

The composition of the soil is very complex. Generally speaking, it is composed of three phases of solid, liquid and gas such as minerals, organic matter produced by the decomposition of animal and plant residues, water and air. The full determination of soil minerals: that is, the determination of silicon, aluminum, iron, content of manganese, titanium, phosphorus, potassium, sodium, calcium, magnesium), soil active silicon, aluminum, iron, manganese content, soil total nitrogen, total phosphorus and total potassium content, soil effective nutrients: organic matter, ammonium state Determination of nitrogen, nitrate nitrogen, available phosphorus and potassium content, soil trace element content and available trace element (iron, boron, manganese, copper, zinc and molybdenum) content determination, soil organic matter content determination, and soil pH, soil cation exchange Quantity, determination of soil exchangeable base composition, etc., soil pH detection, including total soil mineral content, organic matter content, total nitrogen content, effective nutrient content, soil pH, soil water content, soil water potential, saturated and unsaturated hydraulic conductivity , water constant, soil seepage rate, soil mechanical composition, soil specific gravity and soil bulk density, soil porosity, soil structure and microaggregates, soil consolidation, soil expansion and contraction, soil air composition and respiration strength, soil temperature and Thermal conductivity, soil mechanical strength, soil bearing capacity and stress distribution, as well as soil electromagnetic cation exchange capacity and exchangeable base composition all need to be tested to know. When testing soil, in order to obtain accurate results, multiple tests are generally carried out , the detection efficiency of the existing detection equipment is low, and the soil particle size is not the same, and the detection accuracy is also different. In view of this situation, a detection equipment and its detection method for soil composition are proposed
