The invention discloses a device for simulating a soil nutrient transfer rule. The simulation device comprises a rainfall component, a bracket, and a transparent box body used for containing soil to be simulated, wherein multiple sampling holes are formed in the side face of the box body; multiple drainage holes are formed in the bottom of the box body; the bracket comprises a base, a frame and an angle adjusting component; the angle adjusting component comprises two positioning rods and a supporting rod; the two positioning rods are arranged on the base opposite to each other; multiple positioning holes at preset intervals are formed in each positioning rod; the supporting rod penetrates through the two positioning holes in the two positioning rods and crosses the two positioning rods; the box body is arranged in the frame; one end of the frame is hinged to one end of the base; the other end of the frame is supported by the supporting rod; the rainfall component comprises a rainfall instrument, and a mounting rack through which the rainfall instrument is fixed above the bracket; the rainfall instrument comprises a water pipe and two water meters; multiple water outlets are formed in the water pipe; two ends of the water pipe are connected with a water source; the two water meters are arranged at two ends of the water pipe.
Description
technical field [0001] The invention relates to a simulation device, in particular to a simulation device for simulating the law of soil nutrient migration. Background technique [0002] Coal is the main energy source in my country, and its status as the main energy source will remain unchanged for a long time in the future. The large-scale mining of coal has promoted economic development, but at the same time brought a series of environmental problems. Land subsidence, surface water and soil loss, coal gangue occupying land, and groundwater loss caused by coal mining have seriously affected the ecological environment of the mining area. Coal mining leads to ground subsidence, forming slopes of different degrees, causing nutrients in the soil to migrate due to different slope angles, and affecting land quality. Therefore, it is necessary to study the influence of different subsidence ranges on the migration of soil nutrients under rainfall conditions, and to explore its mi...
