Summary of the invention
The objective of the invention is to make a kind of paddy rice-dedicated fertilizer material take biomass power generation waste and biological black wood charcoal as main raw material, energy-conserving and environment-protective are that paddy growth improves nutrient, improve the output of paddy rice.
Another object of the present invention is to provide a kind of preparation method of paddy rice-dedicated fertilizer material.
To achieve these goals, the present invention by the following technical solutions
A kind of paddy rice-dedicated fertilizer is characterized in that comprising following component by weight percentage: 20%-25% biomass power generation waste, the biological black wood charcoal of 2%-5%, 30%-38% urea, 20%-25% primary ammonium phosphate, 15%-20% Repone K and 5%-10% tackiness agent add the water granulation and form.
Tackiness agent is red soil, and the addition of tackiness agent and moisture all can affect size and the compactedness of granulation, so tackiness agent is the 5-10% of gross weight; The interpolation weight of moisture is the 1%-5% of gross weight, and it is too many to add water, and then tack of materials is too large, can't granulation; Add water very little, then material is loose, and granulation can not be shaped.
A kind of preparation method of paddy rice-dedicated fertilizer material is characterized in that first biomass power generation waste and black wood charcoal being mixed, and adds tackiness agent, mixes rear adding primary ammonium phosphate, water, mixes; Add again afterwards Repone K and urea, adopt the disc-type granulating machine granulation.
Because power station waste and biological black wood charcoal are alkalescence, and the water-retaining capacity of urea is strengthened under alkaline condition, and can cause the volatilization of ammonium, and then weakens the fertilizer efficiency of fertilizer.Invention mixes power station waste and biological black wood charcoal first with tackiness agent and the primary ammonium phosphate of acidity, pH adds Repone K and urea after transferring to about 6 again, will reduce like this volatilization of ammonium.The process need of simultaneously granulation carries out at normal temperatures, so also can reduce nitrogen loss.
Biological black wood charcoal surface porosity, porous that the present invention adopts, have larger specific surface area and adsorptivity, fine granularity biomass power plant waste has stronger water-absorbent, the fertilizer of preparation is particulate state, diameter is 3-4mm, pH is about 6, the shortcoming of avoided traditional primary ammonium phosphate to be easy to volatilize, smell being choked the people; Water content is 7.19%, and unit weight is 5.32g/cm
3, overcome the shortcoming that urea itself is easy to deliquescence.
Table 1 is the contained component of biomass power generation waste and physical and chemical index table, and wherein silicone content is higher, and silicon is the beneficial element of paddy growth.Practice shows that silicon has important effect to Rice Photosynthesis, enhancing plant intensity, the plant type of improving, raising to the aspects such as resistance, alleviation heavy metallic poison and raising output of lodging and disease and pest.
The contained component of table 1 biomass power generation waste and physical and chemical index
The particle diameter of biological black wood charcoal has certain adsorptivity less than 0.25 mm, can increase the compactedness of gained particle in the granulation process.And because biological black wood charcoal density is little, if consumption is too large, then greatly finally cause the granulation failure because of the shared volume of biological black wood charcoal; And the ash element that biological black wood charcoal contains such as K, Ca, Mg are soluble state, thereby increase the content of soil ash element.Magnesium is the essential element of crop growth, is the composition of chlorophyll and hormone, is the activator of plurality of enzymes in the plant materials, can promote the synthetic of protein, to the photosynthesis important, can promote the growth of paddy rice, improves rice yield.
Biological black wood charcoal not only contains a large amount of element silicons, contains simultaneously the organic matter of high level, abundant phosphorus, potassium element (seeing Table 2).Organic matter helps to improve the quality problems of soil.And potassium element can improve the leaf photosynthesis characteristic, delays to bloom to ripening period functional leaf and Senescence of Root System.The researchs such as Yin Wen think, execute potassium and make rice tillering early, and the middle and later periods blade is blue or green elegant, and life has enlarged photosynthetic area, has improved photosynthetic productivity, is conducive to form more photosynthate, have promoted the grouting, solid of seed.
Table 2 is the contained component of biological black wood charcoal and physical and chemical index tables that wheat stalk is made
