Ammonia volatilization is an important way for nitrogen nutrition loss, and ammonia entering the atmosphere can enter a natural ecological system again along with dry and wet sedimentation, so that the nitrogen content in soil and water is increased, and a series of environmental problems such as water eutrophication, soil acidification, biological diversity reduction and the like are caused. The ammonia volatilization process is not only influenced by the physical and chemical properties of soil such as pH, cation exchange capacity and the like, but also closely related to natural environmental factors such as illumination, temperature, moisture, wind speed and the like. Due to the rise and fall of tidal water, a narrow and long zone is repeatedly located between the high tide line and the low tide line near the sea-land boundary line, and the narrow and long zone is called as a tidal zone. The tidal zone has more frequent water level fluctuation and more variable weather has more influence on the accurate determination of the ammonia volatilization of the soil.
In the related art, the common collection method for ammonia volatilization adopts a ventilation method in many cases. The sampling device is made of a polyvinyl chloride hard plastic pipe, and two pieces of sponges uniformly soaked in a phosphoglycerol solution (a mixed aqueous solution of 5% phosphoric acid and 4% glycerol) are respectively placed in the plastic pipe at a certain distance. During sampling measurement, the sponge at the lower layer of the sampling device is taken out and is completely immersed into 300mL of KCl solution (1mol/L), oscillation is carried out for 1h, and the content of ammonium nitrogen in the leaching solution is measured by an indophenol blue colorimetric method. The following technical drawbacks exist:
(1) the sampling device is directly exposed in the air, so that the upper sponge layer is often influenced by the sedimentation process of the rain, snow and other atmosphere, and if the sampling device is applied to the tidal zone and other areas which are easily influenced by water level fluctuation, the seawater carrying exogenous impurities flows backwards into the ventilating device, so that the accuracy of the measuring result is influenced;
(2) during measurement, ammonia needs to be leached again, the leaching liquor in the sponge needs to be extruded by means of a tool, the operation is complicated, and measurement errors are easy to cause;
(3) the sponge soaked in the glycerol phosphate solution is easy to slide in the plastic tube, and the continuity of the sampling process and the stability of the measuring result are seriously influenced.
