Soil moisture has five functions in the process of plant growth: 1. The soil moisture condition directly affects the absorption of nutrients by crops; 2. The decomposition and mineralization of organic nutrients in soil cannot be separated from water, 3. The chemical fertilizer applied to the soil is only Can be dissolved in water, 4, to raise the segregation of the root surface of the migration, 5, and the root system of nutrient absorption must be achieved through the moisture medium.
The above paragraph simply describes the effect of soil moisture on the plant. Insufficient or excessive soil moisture will affect the normal growth of the plant. The main expression is: in the absence of soil moisture, plants can easily die due to lack of water. When the soil moisture is insufficient, the plants will be relatively short and unable to grow normally; when the soil water is abundant, the plants can grow robustly and at the same time can produce high yields; when the soil moisture is too high, the roots of the plants can not be maintained. Breathe normally and die. The measurement of soil moisture can be measured using a soil moisture monitoring system. It can perform long-term, regular monitoring and recording of various types of soil, and can be quickly measured and recorded in real time.
The advantage of multi-point soil moisture monitoring system is not only this, it records the data is combined with the sampling date and time, at the same time this instrument has RS232 interface, can upload the measurement results into the computer, the instrument itself carries The calculation software has a powerful data processing function, which can form a graph of the collected data and display it visually. The collected data can also be stored as an EXCEL spreadsheet file, allowing users to save and process data, or use specialized software for data processing, drawing bars, pies, and prints.
The five functions of soil moisture show the importance of soil moisture
The five functions of soil moisture show the importance of soil moisture in the growth process of the crop can not be separated from all variables in the environment. Such as light intensity, carbon dioxide, soil moisture and so on. Although they are variables, we can regulate them properly and use appropriate environmental recorders to perform the process of understanding. Here's a simple look at soil moisture testing.
