In the study of soil moisture, the single use of water content can not explain the whole situation of soil moisture and its effectiveness. The observation results show that different soils treated by the same method have different moisture content; if the soil content is the same, the water content is the same, the plant growth and development The impact is often different. At present, the thermodynamic meaning is more commonly used in the world, but still using the mechanical point of view to explain the water energy state in the soil, collectively referred to as soil water potential. The main advantages of using soil water potential to describe soil moisture are[2]:1 It shows that the energy state of soil moisture, rather than a simple quantitative relationship, can explain well when the soil moisture is more or less. Due to the difference in the work done by the plant's water absorption, the crop growth situation is different; the water index is unified and the application is provided. Convenient (the static soil moisture content does not have a reunification for different soils) the moisture index, such as the field moisture content of the water constant, there are great differences in the sand and clay, the results are difficult to compare with each other.); » can be unified Measure the state of water at any time and anywhere in a soil-plant-atmosphere continuum, and relate soil water to plant growth and meteorological factors, taking into account water The circular motion.
The traditional view did not regard soil, plants and atmospheric continuum as a whole, and did not consider various factors that may affect the water status of the system. With the development of soil-plant and atmospheric-moisture-related theories and experimental techniques The improvement in the precise determination of the interrelationship between water potential, heterotrophy, moisture content and water flux in soils and plants has become possible. There is currently an update on the effectiveness of soil moisture, ie the rate at which plants absorb water. The sum is not only a function of soil moisture content and soil water potential, but also depends on the ability of the root system to absorb water from the soil it is in contact with, as well as on the ability of the soil to supply water and transport water to the root system at a sufficient rate; these Depends on the characteristics of the plant; also depends on the soil properties; at the same time largely depends on the meteorological conditions.
Soil moisture determination by soil moisture analyzer can be concluded that the assessment of the effectiveness of soil moisture needs to fully consider the three major factors, soil, plants and meteorological conditions. All need to be based on the theory of moisture transport in the soil, and must also be combined with the growth, reaction and yield of the crop.
Measurement of Soil Moisture in Farmland by Soil Moisture Analyzer
The state of soil moisture directly affects the characteristics of the soil and the growth of plants, and also affects the distribution of plants and changes in microclimate. Under natural conditions, there is a certain contradiction between the water supply of dry farmland and the water requirements of crops, especially in arid and semi-arid regions. The soil moisture content can not always meet the growth of crops, and it seriously affects the growth, development and yield of crops. Therefore, it has very important guiding significance for the study of soil moisture determination. Soil moisture measurements can be measured using a soil moisture analyzer.
