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...

Abstract

The invention discloses a soil column device for simulating leaching, greenhouse gas collection and ammonia volatilization. A soil column is vertically arranged on a round plate; water penetration holes are formed in the intersected surface of the round plate and the soil column and are covered with a filtering net; a round water blocking ring surrounds the periphery of the round plate; the bottom of the round plate is connected with a leaching solution water collection tank; a leaching solution collection pipe which is communicated with the leaching solution water collection tank is arranged on the round plate; simultaneously a bottom-free column-shaped box is arranged above the soil column, so that the greenhouse gas collection is realized; in addition, a beaker containing a boric acid solution is arranged in a body of the box, so that the determination of the ammonia volatilization can be realized. The soil column device disclosed by the invention can be used for performing quantitative monitoring on environmental behaviors of soil-plant system nutrients on three aspects including leaching, greenhouse gas collection and ammonia volatilization; and the soil column device is high in integration degree of parts and convenient tot assemble.

Description

technical field [0001] The invention belongs to the field of experimental simulation devices, and relates to a soil column device for simulating leaching, collection of greenhouse gases and volatilization of ammonia. Background technique [0002] At present, in the process of studying soil nutrient leaching, greenhouse gas emissions and nutrient volatilization, due to the difficulty and time-consuming outdoor in-situ experiments, people often arrange simulation experiments indoors. Some existing simulation devices can meet one of the three requirements of nutrient leaching, greenhouse gas emission and nutrient volatilization, such as the soil leaching simulation device with the publication number CN101088621A, the greenhouse gas emission measurement device with the publication number CN2725896Y and Publication number is CN203606187U simple and easy soil volatilization ammonia absorption device. The above-mentioned device only meets the research purpose of one side, but fail...
