Problems solved by technology

At present, most of the raw materials used in traditional anti-caking oil products come from petrochemical products, which are coated on the outside of compound fertilizers, which can alleviate the agglomeration of compound fertilizers, but these mineral oils are not easy to degrade when used in the field, pollute the soil, and cause Increased oil content of the soil reduces soil productivity
On the other hand, the current effective utilization rate of granular compound fertilizer is about 32%, resulting in most of the nutrients not being absorbed by the crops, resulting in a waste of resources

Embodiment 1

[0017] A method for preparing a corn fertilizer for preventing pests and diseases, comprising the following steps: using high-content solid water-soluble fertilizers together with surfactants such as wetting agents, suspension aids, and defoamers as raw materials, shearing them evenly in a mixing kettle, and using The screw pump is pumped into a sand mill equipped with grinding media for grinding and mixing. After grinding to a particle size, it is blended in a brewing kettle to obtain a corn fertilizer for preventing pests and diseases.

[0018] Further, the high-content solid water-soluble fertilizer is made of minerals rich in phosphorus, potassium, calcium, zinc, iron, manganese, magnesium, boron, molybdenum, barium and other elements, and the N-P-K content is >60%.

[0019] Further, the wetting agent is one or more compounds of sodium lauryl sulfate, alkylnaphthalene sulfonate, fatty alcohol polyoxyethylene ether, and sodium dodecylbenzenesulfonate, and the dosage is 0.01...

Embodiment 2

[0024] A method for preparing a corn fertilizer for preventing pests and diseases, comprising the following steps: using high-content solid water-soluble fertilizers together with surfactants such as wetting agents, suspension aids, and defoamers as raw materials, shearing them evenly in a mixing kettle, and using The screw pump is pumped into a sand mill equipped with grinding media for grinding and mixing. After grinding to a particle size, it is blended in a brewing kettle to obtain a corn fertilizer for preventing pests and diseases.

[0025] Further, the high-content solid water-soluble fertilizer is made of minerals rich in phosphorus, potassium, calcium, zinc, iron, manganese, magnesium, boron, molybdenum, barium and other elements, and the N-P-K content is >60%.

Abstract

The invention discloses a preparation method of diseases and pests controlling corn fertilizer. The method comprises the following steps: uniformly shearing raw materials of high content solid water-soluble fertilizer and surfactants of a wetting agent, a suspension aid, a defoaming agent and the like in a mixing kettle, pumping the materials into a sand mill loaded with grinding medium through ascrew pump, grinding and mixing, reaching the grain diameter through grinding and blending in a blending kettle to obtain the diseases and pests controlling corn fertilizer. According to the obtaineddiseases and pests controlling corn fertilizer, the fertilizer can rapidly disperse and dissolve in water, and does not block an irrigation system in case of use, the packaging is simplified, the utilization rate of the fertilizer is improved, the used raw materials are environmentally friendly and easily degradable, the soil and environment are not influenced after long-term use, trace element content of the soil is improved, and therefore the quality of cultivated crops is better.

Description

technical field [0001] The invention relates to a water-soluble fertilizer, in particular to a corn fertilizer for preventing pests and diseases. At the same time, the invention also relates to a preparation method of corn fertilizer for preventing pests and diseases. Background technique [0002] Compound fertilizer is one of the main fertilizers in our country at present. It can not only improve soil fertility, but also an important measure to increase the product per unit area of ​​crops. It is the most basic and most important material input in agricultural production. The early compound fertilizers in my country were mainly based on pellet technology, and the fertilizers produced were mostly granular in appearance, and there was crystallization and agglomeration during the storage period. The countermeasure was to add corresponding anti-caking agents to block water and prevent crystal bridging. Ensure the looseness of compound fertilizer. At present, most of the raw ma...
