Description
Technical field
The invention belongs to the technical field of chemical fertilizer, the more particularly to technical field of fulvic acid composite fertilizer.
Background technology
Existing biochemical fulvic acid composite fertilizer nutrient content is more single, generally comprises only nitrogen, phosphorus, potassium, is easily caused work
Because producing nutritional deficiency phenomenon and undergrowth, for the defect, part biochemical fulvic acid composite fertilizer takes and adds in composite fertilizer thing
The method for entering inorganic microelement, but after these inorganic trace elements are added, plant is relatively low to its absorption rate, causes
Nutritional deficiency phenomenon is yet suffered from, on the other hand, increasingly serious currently used for the disappearance of plant growth element in the soil of long-term cropping,
In the situation without the composite fertilizer for being available for efficient absorption, crop is difficult to healthy growth.
The content of the invention
It is an object of the invention to propose a kind of nutrient content fully, crop absorption ratio is high, absorption rate is fast, and fertilizer efficiency is from list
One functional fertilizer is changed into the biochemical fulvic acid composite fertilizer of multifunctional fertilizer.

N、P2O5、K2The total content meter of O, accounting is 30.0 ~ 50.0%.
Wherein protein hydrolysate powder is that animal protein is hydrolyzed to the powder obtained after amino acid, such as a kind of preferred preparation
Method is:Heated in jar using hydrochloric acid and animal hair, pressurizeing is hydrolyzed, and animal protein is converted into amino with this
Acid, is neutralized thereafter using liquefied ammonia, is then peeled off, is concentrated, being dried, and obtains protein hydrolysate powder.
Preferably:Nitrogenous fertilizer includes amidonitrogen, nitrate nitrogen and ammonium nitrogen in the azophoska.
Further preferably:The nitrogenous fertilizer includes amidonitrogen, the nitre of 5 ~ 30% percentage compositions of 50 ~ 90% percentage compositions
State nitrogen and 5 ~ 30% ammonium nitrogen.
Another preferred version of the biochemical fulvic acid composite fertilizer is:B component presses matter in the biochemical fulvic acid composite fertilizer
Amount part meter, including 5 ~ 20 parts of biochemical fulvic acid, 5 ~ 15 parts of sodium humate, 10 ~ 25 parts of protein hydrolysate powder, biochemical fulvic acid chelating is more
10 ~ 20 parts of element powder, DA-6(Diethyl aminoethyl hexanoate)0.1 ~ 1.0 part, 5 ~ 50 parts of tobacco leaf powder of straw.
Another preferred version of the biochemical fulvic acid composite fertilizer is:Also include the fertilizer containing magnesium elements in the component A.
Another preferred version of the biochemical fulvic acid composite fertilizer is:The fertilizer containing magnesium elements is magnesium sulfate.
Another preferred version of the biochemical fulvic acid composite fertilizer is:The azophoska is by urea, ammonium nitrate phosphorus, sulfuric acid
Ammonium, MAP, potassium sulfate composition.
Another preferred version of the biochemical fulvic acid composite fertilizer is:The biochemical fulvic acid composite fertilizer is by following components group
Into:100 ~ 500 parts of urea, 50 ~ 100 parts of ammonium nitrate phosphorus, 30 ~ 300 parts of ammonium sulfate, 80 ~ 200 parts of MAP, potassium sulfate 100 ~
300 parts, 5 ~ 10 parts of magnesium sulfate, 10 ~ 20 parts of biochemical fulvic acid powder, 10 ~ 15 parts of sodium humate, 15 ~ 25 parts of protein hydrolysate powder is biochemical
12 ~ 20 parts of fulvic acid chelated multielement powder, DA-6(Diethyl aminoethyl hexanoate)0.5 ~ 1.0 part, 10 ~ 15 parts of tobacco leaf powder of straw.
Its further preferred version is:The biochemical fulvic acid composite fertilizer is composed of the following components:250 parts of urea, nitre
100 parts of sour ammonium phosphorus, 200 parts of ammonium sulfate, 80 parts of MAP, 300 parts of potassium sulfate, 10 parts of magnesium sulfate, 15 parts of biochemical fulvic acid powder,
10 parts of sodium humate, 12 parts of protein hydrolysate powder, 12 parts of biochemical fulvic acid chelating multielement powder, DA-6(Diethyl aminoethyl hexanoate)1.0 parts, tobacco leaf
10 parts of powder of straw.
Further preferred version is its another kind:The biochemical fulvic acid composite fertilizer is composed of the following components:Urea 500
Part, 20 parts of ammonium nitrate phosphorus, 10 parts of ammonium sulfate, 100 parts of MAP, 300 parts of potassium sulfate, 10 parts of magnesium sulfate, biochemical fulvic acid powder
10 parts, 10 parts of sodium humate, 15 parts of protein hydrolysate powder, 14 parts of biochemical fulvic acid chelating multielement powder, DA-6(Diethyl aminoethyl hexanoate)1.0
Part, 10 parts of tobacco leaf powder of straw.
The base case of the present invention further increases biochemical fulvic acid powder on the basis of azophoska, sodium humate,
Protein hydrolysate powder, biochemical fulvic acid chelating multielement powder, DA-6(Diethyl aminoethyl hexanoate), tobacco leaf powder of straw, wherein biochemical fulvic acid powder its
The effect of itself includes stimulating plant growth, activating soil to strengthen crop anti-adversity, improves quality of agricultural product, and sodium humate is certainly
The effect of body also includes swashing plant growth, and activating soil strengthens crop anti-adversity, improves quality of agricultural product, while itself and nitrogen phosphorus
Nitrogenous fertilizer in potash fertilizer can suppress the loss of the nitrogen of different shape by modes such as complex reactions;Biochemical fulvic acid chelates multielement powder
It is the product after biochemical fulvic acid is chelated with trace element, it has chelated calcium, magnesium, zinc, iron, manganese, can effectively provide work
Required essential elements is grown on thing, while absorbed by crops with the form of organic chelate, thus absorptivity is high;DA-6
(Diethyl aminoethyl hexanoate)Flower and fruit protecting can be played, stimulates the effect such as plant growth;Tobacco leaf powder of straw itself is rich in nicotine, can kill insect,
Guarantee that plant growth is healthy and strong.
From for system, with content fully, biochemical fulvic acid is except effects such as offer nutrients for the element species of the present invention
Outward, the absorption that biochemical fulvic acid chelates multielement powder can be strengthened, thus makes crop to lack various trace elements, and absorb speed
Rate is fast.
Nitrogenous fertilizer includes amidonitrogen, nitrate nitrogen and ammonium nitrogen in further preferred version, and wherein amidonitrogen is in soil
Ammonium nitrogen, ability utilization absorbed by crops, without volatilization, when fertilizer efficiency is played must be hydrolyzed into earth in the presence of urase
Between relatively late, but fertilizer efficiency period is longer, can reach more than 1 month;The characteristics of ammonium nitrogen, can directly be absorbed by crop, high volatility, fertilizer
Effect is rapid, but fertilizer efficiency period is short, and utilization rate is minimum;Nitrate nitrogen can directly be absorbed by crop, and fertilizer efficiency is rapid, than ammonium nitrogen faster, its
Volatility is low with respect to ammonium nitrogen, but denitrification can occur when using under the environment such as rice terrace, becomes nitrogen volatilization loss,
The present invention has taken into full account the respective performance of this three, is allocated as being best suitable for crop and carries out long-acting, efficient nitrogen absorbing
Combination.
The invention has the advantages that:
(1)Several functions agent synergy, with obvious fertility synergistic effect, makes suction of the crop to every kind of component in the present invention
Receipts and utilization rate are above situation about individually using;
(2)While fertility synergy, demand of the crop to different elements is taken into full account, provided under less component composition
Sufficient nutrient;
(3)Amidonitrogen, nitrate nitrogen, ammonium nitrogen used in nitrogenous fertilizer, and the adjustment effect that passes through other components, make the crop can
Keep in a long time fully absorbing nitrogen;
(4)Except fertility is abundant, in addition to comprehensive nutrition, the present invention is also equipped with the pest-resistant ability such as disease-resistant, with multifunctionality.
