Embodiment Construction
[0023] The present invention will be further described below in conjunction with the accompanying drawings.
[0024] Such as figure 1 and 2 As shown, a soil column device for simulating leaching, greenhouse gas collection and ammonia volatilization can be used for simulating leaching, greenhouse gas collection and ammonia volatilization respectively by assembling the device.
[0025] When the device is used to simulate leaching, the specific setting of the device is: the soil column 3 is vertically arranged on the circular plate 7, and the intersecting surface of the circular plate 7 and the soil column 3 (that is, the circular surface where the circular plate 7 and the soil column 3 contacts ) is provided with permeable holes and is covered with a filter screen 5 to prevent the soil from clogging the small holes or flowing into the lower sump with water. A water retaining ring 15 surrounds the circular plate 7 to form a water collection area. The bottom of the circular pl...
