Specific implementation mode
To keep the technical problem to be solved in the present invention, technical solution and advantage clearer, specific implementation will be enumerated below
Example is described in detail.
The object of the present invention is to provide a kind of nano-sized carbon synergy fertilizer, contain potassium nitrate (weight percent) 20-
25%, calcium nitrate (weight percent) 7-10%, magnesium nitrate (weight percent) 5-7%.Not only can to crop provide nitrogen,
The nutrients such as potassium, calcium, magnesium, but also be the important activator of nano-sized carbon.So-called activator is to refer to activation organic matter
Substance, substantially a kind of oxidant, potassium nitrate, calcium nitrate, magnesium nitrate are all a kind of strong oxidizers, and nano-sized carbon passes through oxygen
Agent is converted into special small molecule organic matter, bioactivity enhancing, functional group quantity and matter to the oxidation of biomolecule
Amount all increases substantially, and physiological stimulation effect is also more strong；
It contains urea (weight percent) 20-23%, potassium nitrate (weight percent) 20-25%, calcium nitrate (weight
Percentage) 7-10%, so, the present invention equally, contains amidonitrogen and nitre state simultaneously with the world advanced " no pressure nitrogen solution "
Nitrogen, crop are easy to absorb, and fertilizer efficiency is good.Amidonitrogen molecular volume is small, and diffusivity is big, readily penetrates through cell membrane and enters cell, inhales
High income, and crop root can be promoted from the more nitrogens of soil absorption.Nitrate nitrogen exists with anionic form, mobility
Greatly, fertilizer efficiency is fast, directly effective to crop after fertilizer dissolving, even if in the case where soil moisture content is low, and so.Two
The nitrogen collective effect of kind form can make fertilizer efficiency not only quickly but also lasting；
It contains potassium dihydrogen phosphate (weight percent) 10-14%, is the source of P2O5 and K2O.Potassium dihydrogen phosphate is current
It is chiefly used in soaking seed, sprays or pouring root, so is the preferred raw material of the present invention.Furthermore the phosphorus that crop can absorb, mainly phosphoric acid
Hydrogen salt state phosphorus, wherein with dihydrogen phosphate ions (H2PO4) most easily absorb；
It contains calcium nitrate (weight percent) 7-10% and magnesium nitrate (weight percent) 5-7%, can be carried to crop
For two kinds of moderate-elements of calcium (Ca) and magnesium (Mg).Meanwhile complementary ion of the magnesium as calcium, the validity of calcium can be promoted, make utilization
Rate greatly improves.Calcium nitrate and magnesium nitrate are why selected, and does not have to other, is because calcium nitrate and magnesium nitrate not only provide calcium
(Ca) and two kinds of nutrients of magnesium (Mg), but also it is the important activator of nano-sized carbon in the present invention；
It contains zinc sulfate (weight percent) 3.0-4.0%, manganese sulfate (weight percent) 2.5-3.0%, sulfuric acid
Ferrous (weight percent) 2.0-2.8%, copper sulphate (weight percent) 1.2-1.5%, boric acid (weight percent) 1.5-
2.3%, the micro-element nutritions such as zinc (Zn), manganese (Mn), iron (Fe), copper (Cu), boron (B) can be provided to crop.Due to the present invention
Containing nitrate nitrogen, and manganese can promote the oxidation-reduction process in crop body as reductant-oxidant, when crop absorbs nitrate nitrogen
When, just it must can just be reduced to amino nitrogen (- NH with the presence of the manganese as reducing agent, nitrate nitrogen2) and with organic acid knot
Conjunction forms amino acid, is further formed protein；
It contains nano-sized carbon (weight percent) 0.5-0.8%.Nano-sized carbon mainly plays synergistic effect in fertilizer effect.
Nano-sized carbon is very small, is easy movement in the soil, while nano-sized carbon has extremely strong adsorptivity, can adsorb the nutrient in soil.
Therefore, nano-sized carbon is added in fertilizer, is conducive to absorption of the crop to nutrient, promotes crop yield,
After nano-sized carbon is applied in soil jointly with fertilizer, there are three types of effects：First, nano-sized carbon improves nutrient around root system
Concentration.The nano-sized carbon being moved to around crop root, it is easy to it is adhered to by root exudates, and the adsorptivity of nano-sized carbon, it improves
The concentration of nutrient around root system, meets demand of the root system to nutrient.Second, nano-sized carbon reduces nutrient loss.Nanometer carbon adsorption
Nutrient in chemical fertilizer reduces NH4 +Volatilization, phosphorus fixation and K+The loss of leaching.Third, nano-sized carbon are supported with soil colloid competition
Point.Nano-sized carbon is electrically identical as soil colloid, but the current potential of nano-sized carbon is higher than soil colloid, can be with soil colloid competition for nutrients.
Nano-sized carbon be a kind of small scale, high surface energy activity, surface with negative electrical charge, property is stable and the micro-nano granules of dispersion.It should
Substance has great specific surface area, with a large amount of unstable high energy electrons around it, forms a huge substance
A large amount of zwitterion can be adsorbed in reacting environment, and fertilizer nutrient is then the situation with zwitterion, is absorbed by crops profit
With.In soil, nutrient, plant three's system, nano-sized carbon acts as the role of nutrient carrier.The small-size effect of nano-sized carbon,
The metabolism for accelerating plant, under nano-sized carbon effect, the mitochondria in plant cell largely increases, and increases plant ATP
Energy level and intermediate product generation, to accelerate the respiration of plant, to improve root system to nutriment
Active transport ability.Nano-sized carbon itself is negatively charged, and the nutrient ion around rhizosphere is adsorbed by chemical bond force, and due to root system
The surface H of secretion, root system pectin and root system+、HCO3Exchange ion can capture nano-sized carbon, thus nano-sized carbon can carry nutrient from
Son gathers nutrient surface.Root system surface ion concentration increases as a result, by along chemical potential gradient, promoting various nutrients a large amount of
Into root cell, to improve the utilization rate of fertilizer；
It contains D-sorbite (weight percent) 0.8-1.2%, to chelated microelement zinc, manganese, iron, copper.Together
When, D-sorbite is also a kind of stabilizer and wetting agent, can improve the physicochemical property and function and effect of the present invention, product is made to have
Good adhesive force and plate-out ability can uniformly and completely be attached to blade surface, improve absorptivity and utilization to the utmost
Rate；
Its sodium tripolyphosphate (weight percent) 1-1.5%, sodium tripolyphosphate is a kind of inorganic dispersant, to solids
Matter has extremely strong dispersion force and suspending power, nano-sized carbon can be made to be distributed evenly in solution, will not cause molecule since concentration is big
Between assemble, to keep the commodity of good solution property and product；
It contains citric acid (weight percent) 1.0-1.3%, pH value and stablizing solution for adjusting solution.Simultaneously
Citric acid or a kind of high carbon source organic matter, can not only dissolve fixed phosphorus in soil, and shape can be utilized by so that it is changed into crop
State, but also be the good medium of crop carbon nutrition, crop carbon nutrition can be strengthened, crop C/N ratios are adjusted, be conducive to plant
Growth and development and metabolism.
The present invention nano-sized carbon synergy fertilizer active ingredient (weight percent) be：Nano-sized carbon 0.5-0.8%；Nitrogen (N)
13.4-16%；Phosphorus (P) 5.2-7.2%；Potassium (K) 12.6-16.2%；Calcium (Ca) 1.5-2.1%；Magnesium (Mg) 0.8-
1.0%；Zinc (Zn) 0.7-0.9；Manganese (Mn) 0.6-0.8%；Iron (Fe) 0.4-0.5%；Copper (Cu) 0.3-0.4%；Boron (B)
0.3-0.4%；Sodium tripolyphosphate 1.0-1.5%；D-sorbite 0.8-1.2%；Citric acid 1.0-1.3%；Calcium nitrate 7-
10%；Magnesium nitrate 5-7%.
