Abstract
The invention discloses a fertilizer and a method for enhancing the stability and fertilizer effect of ammonium bicarbonate. The fertilizer is a biomass char/ammonium bicarbonate composite particle fertilizer, wherein the mass ratio of the biomass char to the ammonium bicarbonate is (10-30):100. The method for enhancing the stability and fertilizer effect of ammonium bicarbonate comprises the follow steps of: uniformly mixing the biomass char with the ammonium bicarbonate in the mass ratio of (10-30):100; preparing the mixture into biomass char/ammonium bicarbonate composite particles of which the diameters are between 0.5 millimeters and 3 millimeters to fulfill the aim of reducing volatilization, moisture absorption and agglomeration degrees of ammonia gas in ammonium bicarbonate. The method has the advantages of abundant raw materials, simple technology, low cost, good effect and the like. The fertilizer has a certain carbon emission reduction capability and the functions of improving the physical, chemical and biological behaviors of soil and enhancing soil fertility, and is particularly suitable for soil depletion regions.
Description
Technical field
The invention belongs to technical field of fertilizers, particularly a kind of fertilizer and a kind of method that improves bicarbonate of ammonia stability and fertilizer efficiency.
Background technology
The bicarbonate of ammonia volatile salt of weighing again is called for short the carbon ammonium, belongs to ammonium fertilizer, account for China at present the nitrogenous fertilizer ultimate production about 50%.Carbon ammonium molecular formula is NH
4HCO
3, white crystals, soluble in water, react acid in water.Carbon ammonium highly volatile has the strong impulse stink; Open wide when putting and easily decomposite ammonia, cause nitrogen loss, residual water accelerates deliquescence and makes carbon ammonium caking.Since the carbon ammonium occurred, people were studying the method for decrease carbon ammonium volatilization always.Method commonly used comprises mixing with fertilizer to be used, and mixes with the strong fluorite particle of adsorptivity etc.
Biomass char is the condensation product of biomaterial under the high temperature anoxia condition, has huge specific surface area and very strong surface adsorption ability.The present invention utilizes this character to improve bicarbonate of ammonia stability and fertilizer efficiency.
Summary of the invention
Deposit the problem of ammonia loss by volatilization in the process and the problem of moisture absorption caking in order to solve bicarbonate of ammonia, the invention provides a kind of fertilizer and a kind of method that improves bicarbonate of ammonia stability and fertilizer efficiency.
A kind of fertilizer is characterized in that: the biomass char/ammonium bicarbonate fertilizer of this fertilizer for being formed by biomass char and bicarbonate of ammonia, and wherein, the mass ratio of biomass char and bicarbonate of ammonia is (10～30): 100, preferred (10～20): 100.
Described biomass char is the condensation product of biomaterial under high temperature (200～700 ℃) anoxia condition.Its proportion is 0.5～1.2g/cm
3, black has abundant surface-area, and particle diameter is 0.2～2mm.
Described biomaterial comprises wheat stalk, maize straw, rice straw, Pericarppium arachidis hypogaeae, fruit tree pruning, shrub branch etc.
A kind of method that improves bicarbonate of ammonia stability and fertilizer efficiency, it is characterized in that: the biomass char particle is mixed in the bicarbonate of ammonia, wherein, the mass ratio of biomass char and bicarbonate of ammonia is (10～30): 100, preferably (10～20): 100, mix, make biomass char/bicarbonate of ammonia composite particles, the ammonia that reduces in the carbon ammonium volatilizees and the purpose of moisture absorption degree of agglomeration to reach.
Described biomass char adopts following method preparation:
The first step: biomaterial (wheat stalk, maize straw, rice straw, Pericarppium arachidis hypogaeae, fruit tree pruning, shrub branch etc.) is ground into particle;
Second step: as for (such as lab muffle furnace and other carbonization device) in the resistant to elevated temperatures encloses container, the charing of carrying out under 200～700 ℃, anoxia condition is processed with particles of bioglass;
The 3rd step: after being cooled to room temperature, pulverizing and make the biomass char particle that size is 0.2～2mm.
The advantages such as the present invention has abundant raw material, technology is simple, cost is low, effective, product have certain carbon emission reduction ability and the function of improving the soil physical chemistry biological character, increasing soil fertility simultaneously, are particularly useful for the area of soil depletion.
