Description

Technical Field

[0001] The utility model belongs to the technical field of fertilizer storage, and in particular relates to an underground regulating slow-release fertilizer device. Background Art

[0002] A slow-release fertilizer barrel is a container specially designed for loading slow-release fertilizers, which use special coating technology to achieve the slow release of nutrients to match the growth cycle of crops. The use of slow-release fertilizer barrels not only improves agricultural production efficiency, but also plays a positive role in environmental protection. Let's take a deeper look at various aspects of slow-release fertilizer barrels:

[0003] Slow-release fertilizers use specific technical principles to coat the surface of fertilizer particles with a waterproof membrane shell, so that liquid water cannot pass through, temporarily isolate the fertilizer particles from the outside world, and slowly release the fertilizer in the soil over a period of time or control its release rate. This type of fertilizer is designed mainly to reduce the loss of fertilizer nutrients, especially nitrogen, in the soil, reduce the number of fertilization operations, save labor and costs, and avoid damage to seeds or seedlings caused by excessive fertilization. Types of slow-release fertilizers: compounds that are difficult to dissolve in water, such as ammonium magnesium phosphate, etc., which can remain in the soil for a long time due to their insolubility and are gradually absorbed by crops. Coated or coated fertilizers: such as sulfur-coated urea, which achieve the effect of slow nutrient release by coating special materials on the surface of fertilizer particles. Carrier slow-release fertilizers: fertilizers in which fertilizer nutrients are physically or chemically bonded to natural or synthetic substances. This combination can also achieve slow nutrient release.

[0004] Slow-release fertilizer barrels provide a good storage environment for slow-release fertilizers, protecting them from external factors such as moisture and pollution. The barrel design facilitates the handling and transportation of fertilizers, especially for large-scale agricultural production. In addition to the above, some additional factors need to be considered. Although the initial investment of slow-release fertilizers may be higher than traditional fertilizers, in the long run, the overall cost may be lower due to its efficient utilization rate and reduced fertilization times. Different regions and crops have different fertilizer requirements. It is crucial to choose a slow-release fertilizer variety that suits the local environment and crop needs. Farmers may need professional guidance when using slow-release fertilizers to ensure the correct use of fertilizers and the best results.

[0005] In summary, slow-release fertilizer barrels are not only an indispensable tool in modern agricultural production, but also an important means to promote sustainable agricultural development. By efficiently utilizing resources and reducing environmental pollution, slow-release fertilizer barrels and the fertilizers they carry provide strong support for the realization of green agriculture. With the continuous advancement of technology and the continuous expansion of application areas, slow-release fertilizer barrels will play a more important role in future agricultural production.

[0006] The existing slow-release fertilizer barrels only play the role of storing and transporting fertilizers, and cannot further provide assistance for controlling the delivery of fertilizers. How to control the further storage of fertilizers and ensure the slow-release efficiency of fertilizers during the fertilization process are major problems in the current fertilizer storage and fertilization technology. In the existing field of slow-release fertilizer technology, the fertilization process after planting is generally to dig up the soil or drill holes for fertilization, which will cause certain damage to the environment. In addition, this fertilization method is also very inconvenient, with high labor costs and low fertilization efficiency. Utility Model Content
