Embodiment Construction

[0015] In the thermal decomposition ammonium bicarbonate method for fertilization in greenhouses according to the embodiment of the present invention, the weight ratio of ammonium bicarbonate and water is 95:5 or 90:10 and the reaction shown in Figure 1-2 Heating in the device causes the ammonia bicarbonate to begin to decompose and release ammonia and carbon dioxide; after the water is filtered, the ammonia dissolves into the water to form nitrogen fertilizer, and the carbon dioxide is released into the greenhouse as a gas fertilizer.

[0016] As shown in Figures 1-2, the thermal decomposition ammonia bicarbonate reaction device for fertilization in greenhouses according to the embodiment of the present invention includes a double-cavity barrel 1, an electrical box 2, a sealing cover 3, and a nozzle 5. The double-cavity barrel body 1 is provided with a handle 4 at the middle of the top end, a sealing cover 3 is arranged on both sides of the handle 4, a nozzle 5 is fixed on the se...

Abstract

The present invention relates to a thermal decomposition carbonic acid hydrogen ammonia method, the ammonium bicarbonate and water are mixed with a certain proportion and are heated in the reaction device, the ammonium bicarbonate is leaded to decompose and the alkaline air and carbon dioxide are discharged; after water filtration the alkaline air is dissolved into the water to form the nitrogenous fertilizer, and the carbon dioxide is discharged to the greenhouse to be used as gas fertilizer. The invention has the following beneficial effects: the operation is convenient, quick and safe; NH4HCO3 is converted to aqueous ammonia and CO2, the aqueous ammonia is applied along with water or is ploughed under the farmland after mixing with the farm manure to remain the function of the nitrogenous fertilizer, the CO2 decomposed from NH4HCO3 is fully used and the cost of using CO2 gas fertilizer is reduced, and the output value can be added for 20% above; the directly inputting of NH4HCO3 to the farmland and the emitting of CO2 are avoided and the environment protecting is facilitated.

Description

Technical field [0001] The invention relates to the field of agricultural fertilization, in particular to a thermal decomposition ammonium bicarbonate method for fertilizing in greenhouses. Background technique [0002] Since the 1960s, with the in-depth research on the application of carbon dioxide fertilization in facility cultivation, its effect of increasing production by 20-30% has been widely confirmed and recognized. Therefore, this technology is widely used in developed countries. The main method is Burn kerosene to obtain carbon dioxide. However, due to the high energy consumption and high investment in my country, this method is neither in line with China’s resource and agricultural basic economic reality, nor in line with the sustainable development strategy. Therefore, since the 1990s, Chinese scientific and technological workers have carried out various aspects of carbon dioxide generation. Methodological research. The main methods currently demonstrated are: 1) coke...
