Monitoring System of Root Growth Distribution by Root Analysis System
The growth distribution of crop roots is closely related to the yield and quality of crops. Roots analysis systems are often used for root research in crop cultivation and scientific research. The root analysis system is also called a root analyzer and can automatically measure the length, surface area, and volume of each diameter of the root system with high accuracy and operation method. The growth and distribution of roots in soil depends, on the one hand, on the characteristics of the roots of different plants, and on the other hand on environmental conditions such as soil moisture, temperature and composition. The feeding roots of many trees are mainly distributed in the 15cm soil layer of the soil layer, which is usually rich in organic matter.
According to the distribution in the soil, it can be divided into two types: deep-rooted and shallow-rooted. In general, straight roots are often distributed in deeper soil layers and belong to deep-rooted parts. The fibrous roots are often distributed in shallower soils and live in shallow roots.
In production, the rooted plants can be fertilized properly, and the fibrous roots plants can be adapted to the facilities. However, deep rooting and shallow rooting are relative. If the same plant grows in a fertile soil, rows of trees and ventilation, light is sufficient, and the groundwater level is low, the common root system is more developed and can penetrate into deeper soil layers. If it is grown on earth embankments with poor fertility, poor drainage and ventilation, and high groundwater levels, it is very underdeveloped and mostly distributed in shallower soil layers. Therefore, ploughing and improving soil and combining rational application of 5E can create conditions for the development of the root system.
The growth distribution of the root system is related to the growth and development of the upper part of the plant. That is to say, the plant absorption surface and the photosynthetic surface maintain a balance and seedling period, and the absorption surface is usually much larger than the photosynthetic surface. With the growth of the plant, the proportion It gradually becomes smaller. If the root system is severely damaged, the absorption surface will be reduced, and the growth of the plant's aerial parts will be affected by the lack of water, minerals, and hormones reported. Under natural circumstances, the roots of the plant are often injured or dying due to various factors, plus high temperature, frost, soil nematodes, bites of the hoppers, etc. However, the roots of medlars will quickly form. Therefore, the number and density of roots are as dynamic as the growth of stems and noon. Even if you open carefully during the transplant, many fine roots remain in the soil, and the underground newspaper and ground branches of the plant will be damaged. Cutting off some leaves can ensure the success of the transplant.
Vessel Plate SA516 Gr.70 Plate
Pressure vessel steel plate covers a range of steel grades that are designed for use in pressure vessel, boilers, heat exchangers and any other vessel that contains a gas or liquid at high pressures.
Familiar examples include gas cylinders for cooking and for welding, oxygen cylinders for diving and many of the large metallic tanks that you see in an oil refinery or chemical plant.
There is a huge range of different chemicals and liquid that that stored and processed under pressure. These range from relatively benign substances such as milk and palm oil to crude oil and natural gas and their distillates to highly lethal acids and chemicals such as methyl isocyanate. So of these processes need the gas or liquid to be very hot, whilst others contain it at very low temperatures. As a result there is a wide variety of different pressure vessel steel grades that meet the different use cases.
In general these can be divided into three groups. There is a group of carbon steel pressure vessel grades. These are standard steels and can cope with many applications where there is low corrosion and low heat. As heat and corrosion have more effect on the steel plates chromium, molybdenum and nickel are added to provide additional resistance.
