What is the difference between the function of soil water potential meter and soil moisture meter? There are not many people I am afraid to know. Let's learn and study together. The soil water potential meter measures the water potential of the soil and there are not many people who understand the soil water potential. Soil water potential is the energy needed to extract unit water from the soil under isothermal conditions. The unit is Ba soil moisture saturation, water potential is zero; water content is lower than saturation, water potential is negative, soil is more arid, negative value is greater. The general plant survival range is 0 to -15 bar. The soil water potential measurement process is not affected by various soil properties, and the measurement results can be directly used for irrigation indicators to overcome the disadvantages of taking into account different soil properties during the determination of the soil moisture thermometer. The function of the soil moisture quickness tester is naturally an instrument for detecting soil moisture content. Soil moisture is an important part of the soil and plays an important role in crop growth, water saving irrigation and so on. Through GPS positioning system to master the distribution of soil moisture (water content), to provide a scientific basis for the differential water-saving irrigation, and accurate water supply is also conducive to improving crop yield and quality. After introducing the instruments of soil water potential meter and soil water quickness meter, we will all think that it is not all related to soil moisture, but also data that reflects the soil moisture. Then the effect is not repeated. What about it? Need to know if the soil is suitable for crop survival. Just check soil moisture content? This is not the case, although the soil water potential meter also reflects the moisture content of the soil, but his measurement range is the same in different soil quality, so because of the same soil quality, the same measurement value of the soil water potential meter, Soil moisture is different in different soils. Here we come to a more detailed understanding of the concept of soil water potential: The forces acting on soil water mainly include gravity, the suction of soil particles, and the penetration of solute contained in soil water, so the total water potential of soil is usually expressed as the above various force components. The sum of the points. Soil water potential is generally expressed as a negative pressure and is therefore also referred to as soil moisture tension. The absolute value of the soil water potential is small when the soil is saturated, and the absolute value of the soil water potential is large when the soil moisture content is low. Therefore, the absolute value of soil water potential reflects the difficulty of soil moisture movement and plant water absorption. After reading here, everyone should also understand what is the difference between the function of the soil water potential meter and the soil moisture meter.
It is mainly used for cooling the hot pellets come out of Pellet Mill. The high temperature 70°C-90°C pellet after cooling is less than 3°C-5°C ambient temperature, and reduce to safe moisture content. The cooling pellets not only increase the pellets hardness but also prevent mildew, eaay for storage and transportation.
The counter flow cooling principle is adopted to cool the pellets with high temperature and high moisture. Hot air touches hot pellets and cool air touches cool pellets so as to avoid the pellet surface crack by shock cooling produced by direct contact between cool air and hot pellets. At the same time, the airclosed airclock is adopted for feeding and bigger air inlet area, therefore it can get better cooling effects.
