Saline-alkali land is a big problem in agricultural production, which seriously affects the growth and yield of crops. In order to improve the saline-alkali land, it is very important to choose the right fertilizer.
Suitable fertilizer should be selected for saline-alkali land improvement. Organic fertilizer can improve soil structure and fertility. Compound fertilizer has comprehensive advantages and provides multiple nutrients; Certain fertilizers, such as ammonium sulfate, neutralize alkalinity. The method and amount of fertilization should be controlled to avoid pollution. Reasonable selection and application of fertilizer can effectively improve saline-alkali land and improve crop yield and quality.
Organic fertilizer is also called "farm fertilizer". Including human manure, manure, compost, green manure, cake fertilizer, biogas fertilizer and so on. It has many kinds, wide sources, long fertilizer effect and so on. The nutrients contained in organic fertilizers are mostly organic, and it is difficult for crops to directly use them. Through the action of microorganisms, a variety of nutrients are slowly released, and a steady stream of nutrients are supplied to crops.
Compound fertilizer refers to fertilizers containing two or more kinds of nutrient elements in nitrogen, phosphorus and potassium. Compound fertilizer has the advantages of high nutrient content, less by-components and good physical properties, which plays a very important role in balanced fertilization, improving fertilizer utilization rate and promoting high and stable yield of crops. fertilizer production machine is also something we need to understand.

1, organic fertilizer turning machine: animal manure, domestic waste, sludge, crop straw and other organic solids for industrial fermentation treatment. The equipment is used to carry out comprehensive fermentation on the uniformity of the fermented material. This allows the fermentation tank front end to be free to feed or discharge, and waste such as feces can be retained for a long time.
2, semi-wet material crusher is a professional crushing equipment for high humidity, multi-fiber materials, the use of high-speed rotating blades, crushing fiber particle size is good, high efficiency, semi-wet material crusher is mostly used for manure production and processing, chicken manure, sodium humate and other raw materials crushing effect is good.
3, the mixer mixing speed is fast, uniformity is good, can mix the viscous material adding 30% liquid. When working, there are two relatively rotating blades and rotors in the middle of the mixing, due to the multiple special angles of the blades, regardless of the shape, size and density of the material, it can be quickly and effectively mixed. Using the lower door, fast discharge speed, very little residue.
4. Granulation: the selection of granulation mode is very important in the production of Manure. The production of granulators of various models and specifications, disc granulators, Manure agitating teeth granulators, new type agitating teeth rotary granulators, and Organic fertilizer granulators has the advantages of uniform granulation particles, stable performance, and long service life. They can produce both Manure and inorganic fertilizer and organic inorganic compound fertilizer. The disc granulator is selected for this process.
5. Drying: Although most of the materials after granulation have already formed particles, the moisture and strength of the particles do not meet the standards, and drying treatment must be carried out. A rotary dryer is a rotating cylinder filled with lifting plates inside. Under the action of the plates, the material is fully lifted to exchange heat with the hot air generated by the hot air furnace. As a result, the temperature of the material is raised, and the moisture in it will quickly diffuse outward due to the temperature and steam partial pressure difference. The diffused moisture is carried away by the wind, achieving the effect of drying the material and improving its strength.
6. Cooling: The dried material is transported to the cooling machine through a belt, and the rotary cooling machine is also a rotating cylinder filled with lifting plates inside. Under the action of the plates, the granulated material is lifted and exchanged with the cold air sucked into the cylinder for heat exchange, cooling to near room temperature, further improving particle strength and reducing moisture.
7. Screening: After cooling, there are powdery materials present. A screening machine is used to screen out all the fine powder and large particles. The fine powder is directly returned to the mixer through the return belt conveyor and mixed with the raw materials before participating in the granulation process again. After the large particles are crushed, they are returned to the mixer through the same return belt conveyor as the fine powder. In this way, a complete production cycle is formed, and the semi-finished products enter the coating process.
8. Packaging: Qualified finished products are packaged using a scale for manual weighing or an automatic packaging machine.
9. Conveyor: Configure belt conveyors, bucket elevators, or screw conveyors according to the actual needs of customers.
In summary, the best fertilizers to improve saline-alkali land include organic fertilizers, compound fertilizers and some specific types of fertilizers. These fertilizers can improve soil structure, improve soil fertility, neutralize soil alkalinity, and provide a variety of nutrients needed by crops, so as to effectively improve saline-alkali land and improve crop yield and quality. In practical application, suitable fertilizer and reasonable fertilization scheme should be selected according to the specific situation of saline-alkali land and the needs of crops to achieve the best improvement effect.
Use fertilizer production machine to produce suitable fertilizer, change the soil of this land, so that farmers can increase food production, we have been improving the quality of Huaqiang Heavy Industry, welcome to the site exchange.
