Abstract
A natural multi-function mineral complex fertilizer is characterized in that the fertilizer is made from the raw materials with the following weight percentages: 28-33% of urea, 15-25% of monoammonium, 12-17% of potassium fertilizer, 30-45% of attapulgite powder and 5-10% of humic acid by the preparation method of the conventional fertilizer. The attapulgite powder is a nano-grade porous nonmetallic mineral substance with physical properties of strong adsorbability, cation exchange property, large specific surface area, and the like, wherein, the water absorption rate is equal to or more than 60%, the cation exchange capacity is equal to or more than 20mmol/100g, and the specific surface area is equal to or more than 120m<2>/g; meanwhile, the attapulgite powder is rich in various nutrient elements of potassium, phosphor, calcium, magnesium, sulfur, iron, copper, zinc, molybdenum, manganese, boron, iodine, selenium, and the like; the humic acid can inhibit the activities of urase, and slow down the decomposition of the urea, and the complex compound produced can gradually decompose and release nitrogen, thus prolonging the fertilizer efficiency. The natural multi-function mineral complex fertilizer has the advantages of being applicable to all crops, and realizes the aims of reducing the fertilizer consumption, enhancing the utilization ratio of the chemical fertilizer, reducing agricultural production cost, increasing the yield and quality of farm products, and improving the soil.
Description
Technical field
The present invention relates to the fertilizer that a plant growth is used, specifically a kind of natural multifunctional mineral compound fertilizer.。
Background technology
In the prior art, because the rising year by year of chemical fertilizer amount of application, the particularly imbalance of applying fertilizer for a long time, cause soil nutrient content unbalance, the soil nutritional deficiency symptom is outstanding, and soil compaction, germ increase, vigor descends, and makes utilization rate of fertilizer descend, and the fruit quality descends.Because chemical fertilizer exceeds standard in the soil, some elements lack, and cause in the agricultural-food residual many, the nutrition of chemical fertilizer to lack.The human long-term edible residual food many, that lack human needs's element of chemical fertilizer then must cause the human immunity ability drop, and human body diseases increases; Human body health is caused serious detrimentally affect.The problems referred to above are familiar with by common human consumer already, and Just because of this, people more and more advocate green food.Agricultural science and technology worker's task guarantees us exactly this populous country promptly will allow limited arable land satisfy the demand that people eat, and allows good that people eat again, the health of eating, reduce applying quantity of chemical fertilizer, produce standard compliant vegetables grain, reduce the production cost of farm crop.
Summary of the invention
Purpose of the present invention just provides and a kind ofly can reduce the chemical fertilizer amount of application, replenishes the natural multifunctional mineral compound fertilizer of various trace elements simultaneously to soil.
The present invention realizes that the technical scheme that above-mentioned purpose is taked is: a kind of natural multifunctional mineral compound fertilizer, it is characterized in that it is by following raw materials by weight percent: urea 28～33%, an ammonium 15～25%, potash fertilizer 12～17%, attapulgite 30～45%, humic acids 5～10%; The making method of chemical fertilizer is made routinely.
With the above-mentioned materials of weight proportions making method of chemical fertilizer routinely, be made into technical process of the present invention and be: pulverizing → weighing and burden → batch mixing → chelating granulation → oven dry → cooling → screening.
Pulverize: with urea, an ammonium, potash fertilizer, attapulgite and humic acids separated pulverizing to 80～120 orders;
Weighing and burden: determine the weight percent of urea, an ammonium, potash fertilizer, attapulgite and humic acids, by the proportioning weighing and burden;
Batch mixing: with batch mixes stir batch mixing;
Chelating granulation: use equipment vapor pressure boiler, rotary conveyor and the granulation cylinder of transferring shares; With rotary conveyor with the batch mixing input granulation cylinder of transferring shares, the outlet of vapor pressure boiler vapour pipe is located at the inlet of the granulation cylinder of transferring shares, before batch mixing enters the granulation cylinder of transferring shares, the steam of vapor pressure boiler production sprays in the batch mixing through the vapour pipe outlet, make the water content in the batch mixing reach 22～25%, urea in the batch mixing, an ammonium, potash fertilizer dissolve and enter under the steam high temperature action in the attapulgite crystalline structure body, get the chelating material; The chelating material enters the granulation cylinder of transferring shares and finishes granulation through rotation, gets the chelating granule materials;
Oven dry: use equipment, dram; With chelating granule materials input dram, it is 7～9% oven dry granule materials that drying gets water content;
Cooling: use equipment, cooling cylinder; To dry granule materials input cooling cylinder, finish cooling, get the cooling particulate material;
Screening: according to the production standard regulation, the cooling particulate material is sieved, filter out the present invention who meets the particle diameter requirement.
Also have the packing of detecting after the screening process of the present invention: promptly same batch finished product is detected, the batch ingredients ratio that reaches regulation is salable product and packs.
Pulverizing in the technical process of the present invention and weighing and burden also can be adjusted order, behind the promptly first weighing and burden batch mixing are being pulverized together.
In the prescription of the present invention, except that a large amount of nitrogen of necessary for plant growth, phosphorus, potassium element, also comprise attapulgite and humic acids.Attapulgite is a kind of nanometer porous road nonmetallic mineral, has physical propertys such as stronger adsorptivity, cationic exchange and specific surface area are big, its water-intake rate 〉=60%, cation exchange capacity 〉=20mmol/100g, specific surface area 〉=120m
2/ g; Be rich in various nutrient elements such as potassium, phosphorus, calcium, magnesium, sulphur, iron, copper, zinc, molybdenum, manganese, boron, iodine, selenium simultaneously; Humic acids can suppress to urinate the activity of enzyme, the decomposition that slows down urea, and the complex compound of generation can decompose the release nitrogen gradually; Fertilizer efficiency is prolonged; Polygorskite is that the acting in conjunction of attapulgite and humic acids makes nitrogen, phosphorus, potassium slowly discharge in the farmland, discharge for a long time; in agriculture production, play protect fertile, joint is fertile, soil moisture conservation, water saving, replenish in effects such as trace element, balanced nutrients; thereby can realize reducing the chemical fertilizer amount of application; improve the chemical fertilizer utilization ratio; reduce agriculture production cost; improve quality of agricultural product and output, improve the soil the purpose of preserving the ecological environment.
The present invention is applicable to that various farm crop use.
Be content, method and the result of use of field test of the present invention below:
