Description
Technical field
The present invention relates to agriculture compound manure technical field, especially a kind of composite fertilizer of containing Lumbrukinase, can keeping soil from packing together.
Background technology
At present, use chemical fertilizer on agricultural, have following problem: 1, life-time service chemical fertilizer, cause soil compaction; 2, straw-returning, the organic matter in soil can not decompose very soon; 3, nutrient loss is serious, groundwater pollution.
In addition, in China's agriculture production, this season utilization ratio of chemical fertilizer is very low.At present, China's utilization rate of nitrogen fertilizer is about 30%-35%, and external utilization rate of nitrogen fertilizer is 50-55%, and utilization rate of fertilizer low is the huge waste that causes economically, investigation report for years shows, in the loss of nitrogenous fertilizer of state-owned nearly 1/4th ultimate productions outside the farmland; The 2nd, serious environment pollution, the loss nitrogen is with greenhouse gases N
2The forms such as O spill in atmosphere, cause Greenhouse effect.The nitrogen of loss also can enter underground water and surface water, directly causes body eutrophication, and water quality deterioration and hydrobiont are dead.Cause simultaneously underground water and tap water nitrate content to exceed standard, directly the serious threat human health.
Lumbrukinase is to extract a histone lytic enzyme of preparation in the middle of the earthworm, has the hydrolysis fibrinolytic protein, activates profibr(in)olysin and become the plasminogen function, medically is being widely used.In recent years, Lumbrukinase also comes into one's own in the middle of plant-growth and agriculture production gradually.There are some researches show, Lumbrukinase contains two kinds of antagonistic microbes (styreptomyces globispotus strain and syringin streptomycete) and can also kill virus, the harmful bacteria in soil and plant-growth is had inhibiting material.Find according to test-results for many years, Lumbrukinase can promote stalk to decompose, improve soil and improve the rhizospheric microorganism environment, and the containment soil-borne disease strengthens crop resistance, not only significantly improve crop yield and quality, and reduce applying quantity of chemical fertilizer and improve fertilizer utilization efficiency.Yet current Lumbrukinase is used very limited in agriculture production, on the one hand, due to technical reason, the peasant is difficult to grasp to Lumbrukinase application process and consumption, and the input cost that has increased material and personnel's work is used in the field on the other hand, makes overall economic benefit not obvious.Utilize modern industrial technology, with composite fertilizer and Lumbrukinase common granulation by a certain percentage, in the farmland, disposable applying can effectively address the above problem, and also there is no at present the report about compound Lumbrukinase fertilizer.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of Lumbrukinase composite fertilizer and preparation method thereof, the products obtained therefrom environmental protection, and long-term application may be improved soil aggregate effectively, eliminates soil compaction, strengthens soil penetrability; Improve the shock-absorbing capacity of soil, can alleviate the soil secondary salinization that causes because of excessive fertilization to the harm of crop; Promote that in soil, beneficial microorganism grows, improve utilization rate of fertilizer; Promote crop root growth, well developed root system, strengthen resistance against diseases, obviously volume increase.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows.
A kind of Lumbrukinase composite fertilizer, it comprises following composition: basic chemical fertilizer, antifreezing agent, Lumbrukinase, synergistic agent; Wherein, the content that calculates described antifreezing agent according to the weight permillage is 1.17 ‰-4.90 ‰, and the content of Lumbrukinase is 0.16 ‰-1.20 ‰, and the content of synergistic agent is 0.17 ‰-1.50 ‰.
As a preferred technical solution of the present invention, described basic chemical fertilizer is one or more mixtures in ammonium chloride, ammonium sulfate, urea, powdery monoammonium phosphate, powdery Repone K, powdered potassium sulfate.
As a preferred technical solution of the present invention, described anti-hard caking agent is one or both mixtures in paste anti-hard caking agent, powdered anti-caking agent.
As a preferred technical solution of the present invention, the enzyme activity of described Lumbrukinase is not less than 10000u/mg.
As a preferred technical solution of the present invention, described synergistic agent is one or both mixtures in a-Nafusaku, linear polyacrylamide.
As a preferred technical solution of the present invention, also include binding agent, sulfuric acid, liquefied ammonia in its composition; Described binding agent is one or both mixtures in attapulgite, wilkinite.
The preparation method of above-mentioned Lumbrukinase composite fertilizer, its step comprises:
A, raw material pulverizing, metering, mixing: take basic chemical fertilizer and binding agent, pulverize respectively, be transported to stirring and evenly mixing in mixer;
B, granulation: the raw material of mixing is transported in the spray drum tablets press, sulfuric acid, liquefied ammonia are joined in the spray drum tablets press through the TAV tubular reactor; Under atmospheric pressure state, utilize the chemical reaction heat of sulfuric acid, liquefied ammonia will be the raw material of homogenizing carry out granulation;
C, screening, drying, cooling, regrading: the product that tablets press is produced meets the requirements of particle through screening, send in drying cylinder, drying cylinder opening for feed temperature is controlled at 120 ℃-210 ℃, carry out drying, 50 ℃-70 ℃ of dry rear temperature of charge enter in refrigerating unit, normal temperature is taken out cold wind and is carried out countercurrent ventilating, be cooled to below 35 ℃, through regrading, qualified granular fertilizer is done anti-caking through the cylinder coating machine and is processed;
D coating: add Lumbrukinase and synergistic agent to anti-hard caking agent in the process of coating in, thereby take anti-hard caking agent as carrier, evenly add to Lumbrukinase and synergistic agent in composite fertilizer; Wherein the consumption of anti-hard caking agent, Lumbrukinase and synergistic agent guarantees that the content of antifreezing agent in Lumbrukinase composite fertilizer finished product is 1.17 ‰-4.90 ‰, and the content of Lumbrukinase is 0.16 ‰-1.20 ‰, and the content of synergistic agent is 0.17 ‰-1.50 ‰; Permillage is calculated by weight;
E, metering packing: the fertiliser granulates after cylinder coating machine anti-caking is processed is finished product through metering packing.
Wherein, in step C, drying cylinder opening for feed temperature is controlled in accordance with following standard: be controlled at 120 ℃-130 ℃ during high nitrogen formula, during the high phosphorus formula, be controlled at 190 ℃-210 ℃.
Wherein, in step D, when adopting the paste anti-hard caking agent, the addition means of Lumbrukinase and synergistic agent is as follows:
D-1, the paste anti-hard caking agent is added in dissolving tank, heating for dissolving is added Lumbrukinase and synergistic agent, stirring and evenly mixing; Count by ratio of weight and the number of copies, paste anti-hard caking agent, Lumbrukinase, synergistic agent adding proportion are (5-6): (1-1.5): (1-1.5);
D-2,, the paste liquor that contains Lumbrukinase and synergistic agent that will stir after the volume pump pressurization, be sprayed at the composite fertilizer surface; Every 1000kg finished product, the ratio of adding above-mentioned paste mixture is 2kg-3.5kg.
Wherein, in step D, when adopting Powdered anti-hard caking agent, the addition means of Lumbrukinase and synergistic agent is as follows:
D-1, Lumbrukinase and synergistic agent are added in powdered anti-caking agent to stirring and evenly mixing; Count by ratio of weight and the number of copies, Powdered anti-hard caking agent, Lumbrukinase, synergistic agent adding proportion are (7-9): (1-1.5): 2;
The pulverulent mixture of D-2, mixing is added in parcel cylinder with the speed governing screw feeder, and by the rotation of parcel cylinder, the anti-hard caking agent that is mixed with Lumbrukinase and synergistic agent will be adsorbed onto the compound fertilizer granules surface; Every 1000kg finished product, the ratio of adding above-mentioned pulverulent mixture is 4kg-6kg.
