Problems solved by technology

[0002] At present, most of the chemical fertilizers needed for crop cultivation in the market are high-nitrogen compound fertilizers, high-nitrogen organic-inorganic compound fertilizers, organic fertilizers, microbial fertilizers, etc. The conventional production process of high-nitrogen compound fertilizers and high-nitrogen organic-inorganic compound fertilizers is difficult. Very large, high cost, easy to harden in storage
Organic fertilizers, microbial fertilizers and other nutrients are very low, and the fertilizer efficiency is low. In order to solve these problems, urea is often added and mixed with it to increase nitrogen and increase fertilizer efficiency. However, due to the high solubility of urea, the water solubility is very good. Due to the high dissolution speed, it is easy to burn the seedlings when the amount is large, the nitrogen utilization rate is low, only about 30%, the loss is large, the groundwater pollution is caused, and the duration of the fertilizer effect is short, resulting in the defertilization of crops in the later stage.
At the same time, when mixed with organic fertilizers, organic-inorganic compound fertilizers, and fertilizers containing humic acid and amino acids, they tend to absorb water or bond together with chemical reactions.
In order to solve these problems, urea is usually wrapped with materials such as polyurethane and soluble resins. Although it has the effects of controlled release, improved fertilizer efficiency, and reduced losses, the wrapped film is difficult to dissolve or tolerate in a short time, resulting in secondary pollution of the soil. , the peasants are miserable

[0065] Experimental Example 1 Coated Microorganism Modified Granular Urea

[0066] Overview: Urea is a simple chemical fertilizer with a nitrogen content of 46%. Nitrogen exists in the form of amide nitrogen. Its chemical properties are alkaline and its pH value is between. It has some physical and chemical properties of alkaline inorganic salts and organic salts. The fertilizer effect is single, the dissolution rate is fast when applied, the loss is large, and the utilization rate is low. According to these properties, several raw materials such as threonine, lysine, acetic acid, etc. are selected for physical and chemical reactions with urea, and urea threonine salt, urea lyonate or urea with strong adsorption is generated on the surface of urea Acetate changes the structure and form of amido nitrogen to adhere to and protect various functional bacteria from being killed by amido nitrogen, and protect the long-term survival of beneficial bacteria. The corresponding protecti...
