Straw returning is an important way to increase soil nutrients, increase soil organic matter content, improve soil physical and chemical properties, potassium and phosphorus nutrient conditions, and enhance soil microbial and enzyme activities.
Especially in recent years, the early straw cultivation, the late rice no-till cultivation techniques, the wheat field, rapeseed, Chinese milk vetch and the early crop cover grass technology not only adapt to the characteristics of current agricultural production, but also play the role of grass and fattening. It has multiple functions such as moisturizing grass, adjusting grass with grass, protecting grass with grass, pressing grass with grass, and saving labor. It has multiple advantages of organic fertilizer, biofilm and soil protection vegetation. This technology not only has the basic characteristics of traditional agriculture, but also has the characteristics of modern agriculture, with strong vitality and broad development prospects.
Developing economic green manure to develop green manure production is an effective way to increase organic nitrogen sources and enrich phosphorus, potassium and trace elements in soil. At the same time, green manure is the link between agriculture and animal husbandry. The nitrogen resources contained in green manure exist in the form of protein. It can directly provide the source of protein necessary for humans and animals, and is a high-quality livestock feed. To develop green manure production, it is necessary to take the road of grain and fertilizer, vegetable fertilizer and fertilizer, and improve the direct economic benefits of green manure to fully demonstrate the strong vitality of green manure in agricultural production.
Increasing the utilization rate of manure and manure The preservation, accumulation and application of farmyard manure have a long history in China. In the 1960s, the “four diligences†(diligence sweep, diligence, diligence, diligence) summed up by farmers Eight have" (the cow has a bar, a pig has a circle, a gray house, a manure pool, a person has a toilet, a chicken and duck have a soil temple, a season has a manure, and there is a green manure in the field). The experience is still not outdated, we have to further Seriously sum up the experience of these traditions, and gradually improve them and continue to carry forward.
Promotion of commercial organic fertilizers Since the beginning of the 21st century, refined organic fertilizers and organic-inorganic compound fertilizers have become "newcomers" in the fertilizer industry. Looking forward to the development trend of fertilizers in this century, organic fertilizers will be applied to the soil in the form of commercial organic fertilizers and organic-inorganic compound fertilizers, except directly or after being treated and returned to farmland. As the demand for organic fertilizers in green food production continues to increase, organic-inorganic compound fertilizers will gradually develop to organic fertilizers, and a small amount of inorganic fertilizers will be transported to the concentration of organic fertilizer resources to regulate nitrogen and phosphorus in organic fertilizers. The proportion of potassium or the increase in available nitrogen in organic fertilizers to fully exert the role of organic fertilizers.
The application of organic fertilizer combines traditional agricultural technology with modern agricultural science and technology. It is the relationship between inheritance and development. It is also the best way to recycle materials during production and life. Only multi-fertilizer fields can be used with fertilizer. Achieve the purpose of enhancing the ground force.
Anodizing treatment is a surface finishing process for aluminum that forms a protective oxide layer on the surface of the metal. The process involves immersing the aluminum material in an electrolytic solution and passing an electric current through it. This creates a uniform and durable oxide coating that enhances the corrosion resistance and aesthetic appeal of the metal.
There are two main types of anodizing treatment: sulfuric acid anodizing and hard anodizing. Sulfuric acid anodizing is the most common type and produces a thinner, more decorative layer of oxide coating, while hard anodizing results in a thicker, harder, and corrosion-resistant layer that is ideal for industrial and automotive applications.
Anodizing treatment provides numerous benefits to aluminum products. It increases their resistance to corrosion and wear and tear, making them suitable for use in harsh environmental conditions. The process also enhances the strength and durability of the metal, extending its lifespan and reducing the need for maintenance.
Another advantage of anodizing treatment is its ability to add color and texture to aluminum products. Different dyes can be added to the electrolyte solution to produce a range of colors, from bright and vibrant to more subdued tones. Additionally, different textures and finishes can be achieved through specialized anodizing processes, such as matte anodizing or brushed anodizing.
Anodizing treatment is commonly used in various industries, including aerospace, automotive, construction, and consumer goods. It is an eco-friendly process as it uses no hazardous materials and produces minimal waste. However, it is important to note that anodizing treatment may affect the dimensional accuracy of the product and may mask defects that are present on the surface of the material.
Overall, anodizing treatment provides an effective way to enhance the functionality and appearance of aluminum products. As research and innovation continue to advance, even more advanced and innovative applications of anodized aluminum are expected to emerge.
