Embodiment 1
[0017] A method for monitoring orchard soil ammonia volatilization emissions, comprising the following steps of monitoring method: Step 1: selecting a peach orchard with 3m*3m peach trees as the monitoring object, wherein the fertilization area is required to be within the range of 0-60cm from the trunk;
[0018] Step 2: Select the air exchange room;
[0019] Step Three: Consider NH 4 + For the influence of the migration of nutrient ions, 3 sampling boxes of ammonia volatilization closed air exchange rooms are arranged in the 3 distance intervals of 0-45cm, 45-90cm, and 90-135cm from the vertical direction of the trunk;
[0020] Step 4: There are two columnar ventilation holes on the top of the air exchange room, one is connected to the pvc ventilation rod with a height of 2.5m on the ground through a threaded pipe; One airway tube, filled with 100ml 0.05moL / L H in a glass bottle 2 SO 4 The ammonia gas absorption liquid, another conduit is connected to the vacuum pump, the...
