Problems solved by technology

[0002] In the prior art, due to the increase in the amount of chemical fertilizer application year by year, especially the unbalanced fertilization for a long time, the soil nutrient content is unbalanced, the symptoms of soil nutrient deficiency are prominent, the soil is hardened, the bacteria increase, and the vitality decreases, which makes the fertilizer utilization rate decrease. Decreased quality of plant fruit
Due to the excessive chemical fertilizers in the soil and the lack of some elements, there are many chemical fertilizer residues and lack of nutrients in agricultural products.
Long-term human consumption of food with a lot of chemical fertilizer residues and lack of elements needed by humans will inevitably lead to a decline in human immunity and an increase in human diseases; it will cause serious adverse effects on human health

specific Embodiment approach

[0031] The specific embodiment Example 1 Weigh 280 kg of urea, 200 kg of monoammonium, 170 kg of potassium sulfate, 300 kg of attapulgite powder, and 50 kg of humic acid; according to the production method of conventional chemical fertilizers, proceed according to the following process steps:

[0032] Pulverization: Pulverize urea, monoammonium, potassium fertilizer, attapulgite powder and humic acid to 100 mesh respectively;

[0033] Mixing: Mix and stir the pulverized ingredients evenly to obtain a mixed material;

[0034] Chelating granulation: use equipment steam pressure boiler, belt conveyor and transfer granulation drum; use the belt conveyor to input the mixed material into the transfer granulation drum, and the steam pipe outlet of the steam pressure boiler is set at the entrance of the transfer granulation drum , before the mixed material enters the transfer granulation drum, the steam produced by the steam pressure boiler is sprayed into the mixed material through t...

Embodiment 2

[0038] Embodiment 2 Take by weighing 330 kg of urea, 180 kg of monoammonium, 120 kg of potassium chloride, 310 kg of attapulgite powder, and 60 kg of humic acid, according to the production method of conventional chemical fertilizers, carry out according to the following process steps:

[0039] Pulverization: Pulverize urea, monoammonium, potassium fertilizer, attapulgite powder and humic acid to 120 mesh respectively;

[0040] Mixing: with embodiment 1;

[0041] Chelating granulation: before the mixed material enters the transfer granulation drum, the steam produced by the steam pressure boiler is sprayed into the mixed material through the outlet of the steam pipe, so that the water content in the mixed material reaches 22%, and the rest are the same as in Example 1;

[0042] Drying: drying granular material with a moisture content of 8% after drying; the remainder is the same as in Example 1;

[0043] Cooling: with embodiment 1;

[0044] Screening: with embodiment 1.

Embodiment 3

[0045] Embodiment 3 Take by weighing 300 kilograms of urea, 150 kilograms of monoammonium, 150 kilograms of potassium sulfate, 350 kilograms of attapulgite powder, and 50 kilograms of humic acid, according to the production method of conventional chemical fertilizers, carry out according to the following process steps:

[0046] Mixing: Mix and stir the ingredients weighed above to obtain a uniform mixture;

[0047] Pulverization: pulverize the mixture to 80 mesh;

[0048]Chelating granulation: Before the pulverized mixed material enters the transfer granulation drum, the steam produced by the steam pressure boiler is sprayed into the mixed material through the outlet of the steam pipe, so that the water content in the mixed material reaches 24%, and the rest are the same as in the embodiment 1;

[0049] Drying: with embodiment 1;

[0050] Cooling: with embodiment 1;

[0051] Screening: with embodiment 1.

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 [0001] The invention relates to a fertilizer for plant growth, in particular to a natural multifunctional mineral compound fertilizer. . Background technique [0002] In the prior art, due to the increase in the amount of chemical fertilizer application year by year, especially the unbalanced fertilization for a long time, the soil nutrient content is unbalanced, the symptoms of soil nutrient deficiency are prominent, the soil is hardened, the bacteria increase, and the vitality decreases, which makes the fertilizer utilization rate decrease. The quality of the fruit of the plant decreases. Due to the excessive chemical fertilizers in the soil and the lack of some elements, there are many chemical fertilizer residues and lack of nutrients in agricultural products. Long-term human consumption of food with a lot of chemical fertilizer residues and lack of elements needed by humans will inevitably lead to a decline in human immunity and an increase in human di...
