Abstract

The invention relates to a small detachable soil column simulation device, which is characterized in that the device includes: a liftable support platform; a soil column bottom unit; and a number of combined column units with openings at both ends connected in series from top to bottom. , the bottom of the combined column unit at the bottom can be detachably connected to the top of the soil column bottom unit; a detachable screen is fixed above the interior of the soil column bottom unit. The detachable screen can prevent direct mixing between soil and quartz sand. ; An infrared lamp located above the uppermost combined column unit and fixedly installed on the top of the liftable support platform for simulating the evaporation process; a liquid adder fixedly installed on the top of the liftable support platform for simulating the water adding process; and , a jet is hung above the uppermost combined column unit, and the liquid doser outlet is connected to the jet through a pipeline. The invention can be widely used in soil column simulation tests.

Description

technical field

[0001] The invention relates to a small detachable soil column simulation device and belongs to the technical field of agricultural soil sampling. Background technique

[0002] Soil is the basic condition for human survival and all social activities. It is an important factor to ensure the growth and development of crops. With the rapid development of modern industry and the continuous increase of the world population, the demand for agricultural land is also increasing. Therefore, , Improving the physical and chemical properties of soil, improving soil quality, and increasing the yield and quality of crops in limited land are important guarantees for agricultural development and sustainable agricultural development. Among them, soil science research is to improve soil quality and crop yield in limited land and quality of the important way. The packed soil column simulator is a commonly used equipment in soil science research. It can use scientific means to ...
