Talking about the fertilization mode of low carbon emission reduction

The development of a low-carbon economy is a major trend in the global economic development. Under the current favorable situation, further development of fertilizer production, energy conservation and carbon reduction functions is of great significance to the development of low-carbon economy.

 

Seeking fertilization mode for low carbon emission reduction

 

Since fertilization is a technical measure that must be taken in human agricultural production activities, and the ecological environment is related to the survival and development of human beings, the fertilization model for low-carbon emission reduction is sought for the current problem of ecological environmental pollution caused by unreasonable fertilization and unscientific fertilization in China. It is the only choice for humans at present.

 

Improve fertilization

 

Fertilizers should be avoided and applied as much as possible, especially nitrogen fertilizer. When used as a base fertilizer, it can be combined with deep tillage before planting to bury the fertilizer in the ground to avoid the loss of nutrients. Phosphate fertilizer is generally used as a base fertilizer, and no top dressing is used. When the crop is topdressed, fertilization on the shady surface can not only improve the fertilizer utilization rate, but also promote the growth of the roots of the shady surface and enhance the lodging resistance of the crop. Pay attention to the application of organic fertilizer when fertilizing. Organic fertilizer can not only balance the nutrient ratio of soil, but also promote the breeding of soil microbes, improve the water retention and fertilizer retention capacity of the soil, and improve the soil.

 

Soil testing and formula fertilization

 

Soil testing and formula fertilization is based on soil testing and fertilizer field experiment. According to crop fertilizer requirement, soil fertility performance and fertilizer effect, based on rational application of organic fertilizer, nitrogen, phosphorus, potassium and medium and trace elements are proposed. The amount of fertilizer applied, the period of fertilization and the method of application. The core is to regulate and solve the contradiction between crop fertilizer and soil fertilization. At the same time, it can specifically supplement the nutrients needed for crops. What elements are added to the crops without any elements, how much will be needed to achieve a balanced supply of nutrients, not only to meet the needs of crops, but also to reduce the amount of fertilizer and avoid environmental damage. Pollution.

 

Developing new fertilizers

 

Controlled slow-release fertilizers, bio-organic fertilizers, organic-inorganic compound fertilizers and other new fertilizers can directly or indirectly provide essential nutrients for crops; regulate soil pH, improve soil structure, improve soil physical and chemical properties and biological properties; adjust or improve The growth mechanism of the crop; improving the quality and properties of the fertilizer and increasing the utilization of the fertilizer. The development trend of new fertilizers is closely related to the development trend of agriculture. Only by accelerating the development speed of new fertilizers can agricultural production be developed along the direction of high yield, high quality, low consumption and high efficiency.

 

to sum up

 

Under the situation that the world is advocating a low-carbon economy, only by vigorously developing a fertilization model with low-carbon emission reduction, can the economic, social and environmental benefits of modern agriculture be organically integrated, develop modern ecological agriculture, and protect the ecological environment. Harmony and unity between human and ecological environment.

 

Water Level Meter

The steel ruler water level meter is the most accurate way to measure the water level. A metric or imperial scaled steel ruler attached to a probe that is mounted on a metal or plastic steel. It is usually used to measure the water level in wells, boreholes and water level pipes. It is especially suitable for the observation of groundwater level in hydropower projects or the manual inspection of dam body immersion lines of earth and rock dams. The devices are characterized by a simple, fast and reliable measurement acquisition.
