Abstract

The invention provides an experimental device for demonstrating soil characteristics. The device comprises a box body which is internally provided with a soil column experiment region, at least one accessory storage region, and a soil sample storage region; at least one hollow soil column is arranged in the soil column experiment region; a water tank is arranged in the accessory storage region, isa water tank with a controllable water level, and comprises a water tank body, a water tank top cover, a circular pipe, a water valve and a hose; at least one circular hole is formed in the soil sample storage region, and the hollow soil column is arranged in the circular hole; demonstrating is carried out from the aspects of soil profile, soil sample treatment, various characteristics of soil and the like through different combinations of equipment in different regions. In terms of device design, the device has the advantages of being simple in structure, transparent in whole body, easy to demonstrate and observe, compact and portable. In terms of function implementation, the device has multiple functions of soil profile simulation, soil sample treatment, demonstration of multiple characteristics of soil and the like.

Description

technical field [0001] The present application relates to the field of demonstration of soil properties, in particular to an experimental device for demonstration of soil properties. Background technique [0002] Soil is a loose material layer on the land surface, which is slowly developed from rocks through long-term weathering and bioaccumulation. It can supply and coordinate the fertility needed for plant growth, including water, nutrients, gas and heat, etc.; soil is the basis for our human survival, and its importance is manifested in four aspects: First, soil is the base of agricultural production . Agricultural production depends on the growth of plants, while the growth and reproduction of land plants must rely on soil. Soil is the nutrient pool of organisms. It has the function of rainwater conservation, supports organisms, plays an important role in nutrient transformation and cycle, and plays a stabilizing and buffering role in environmental changes. Second, so...
