Abstract

The invention discloses an ammonium bicarbonate compound stabilizer and a preparation method thereof. Zeolite, magnesium oxide, activated carbon, monoammonium phosphate, sepiolite, bentonite and semi-hydrated gypsum are subjected to smashing pretreatment and mixed according to weight ratio to obtain mixture; and then the mixture is mixed with ammonium bicarbonate in a ratio of (4-25):(75-96), so that stability of ammonium bicarbonate can be effectively improved. According to the invention, the zeolite, magnesium oxide, activated carbon, monoammonium phosphate, sepiolite, bentonite and semi-hydrated gypsum which contain a lot of essential nutrient elements for plant growth are taken as the raw materials for preparing the ammonium bicarbonate compound stabilizer, technology is simple, complex equipment is not required, and stability of ammonium bicarbonate can be improved after the compound stabilizer is mixed with ammonium bicarbonate in proportion; and when the compound stabilizer is applied to agricultural production as fertilizer, effect period of fertilizer can be greatly prolonged, production cost can be reduced, soil conditions and quality of agricultural products can be improved, and crop yield can be increased.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to an ammonium bicarbonate composite stabilizer and a preparation method thereof. Background technique [0002] Due to the unstable chemical properties of ammonium bicarbonate, it is easy to agglomerate, volatilize and decompose, and it is extremely inconvenient for transportation and storage. When it is used as an agricultural fertilizer, improper application will also cause a large loss of nitrogen and decomposition loss, resulting in Ammonium bicarbonate fertilizer has a short effective period, low nitrogen utilization rate, pollutes the environment, wastes energy, reduces crop yield and quality of agricultural products, and makes the rate of return on agricultural inputs lower and lower. [0003] In order to overcome the above-mentioned shortcomings of ammonium bicarbonate itself, some people try to develop large particle ammonium bicarbonate, coated ammonium bicarbonate ...
