How to digitalize soil fertility?
The discussion of soil fertility is a prerequisite for agriculture, but how to use digital to reflect soil fertility, or to measure the quality of soil fertility, how is this process completed? In the past, the level of soil fertility of plants under the same atmospheric conditions was determined by the presence of soil internal matter and energy, and the extent to which they were transformed by plants.
Nowadays, with the advancement of science and technology, soil fertility can be expressed numerically. The soil nutrient quickness meter can help us determine the status of soil nutrients in order to judge whether the soil fertility is good or bad. The values ​​measured by the soil nutrient fastness tester include soil nitrogen and phosphorus. Potassium content, pH, pH, salinity, etc., provide the basis for the measurement of soil fertility.
This understanding has attributed soil fertility to both soil and plant factors. On the same soil, that is, when the soil has a certain amount of matter and energy, the ability to absorb and utilize plants is not the same. Therefore, it can be expressed as two fertility conditions at the same time. For plants that are ecologically suitable for such soils, The ability to absorb and use is strong, and the soil shows high fertility. However, plants that are ecologically unsuitable for such soils have a weak ability to absorb and use them, and the soil exhibits low fertility.
Fertile or infertile soils should be plant-oriented. Therefore, it is easy to understand the ecological relativity of soil fertility from the ecological requirements of plants, but for a long time, it was considered that soil fertility was the highest. The amount of water and nutrients, as well as the view that fertility or infertility is only relative to the parent material, have long held the minds of people and led to the prevalence of natural or human cultivation.
Because of the different plant ecological requirements, it will be a fertile soil for an ecologically demanding plant, and the plant for another ecological requirement may be such an objective fact that it is not fertile, but it is not paid attention to by people. Therefore, soil fertility is ecological, and the ecological relativity of soil fertility is based on the concept of soil fertility.
Train Piston Pin, a cylindrical pin mounted on the skirt of the piston, passes through the small hole in the middle of the connecting rod and is used to connect the piston and the connecting rod, passing the gas force on the piston to the connecting rod. It is usually made of high quality alloy steel and made hollow.
Train Piston Pin materials are generally low carbon steel or low carbon alloy steel, such as 20, 20 mn, 15Cr, 20 cr or 20 MNV. The outer surface is hardened by carburizing and then refined and polished. This not only improves the surface hardness and abrasion resistance, but also ensures high strength and impact toughness.
