Using soil thermometer matters needing attention

The soil thermometer can accurate judgment, and measuring soil temperature, compact design, easy to carry, can replace the traditional thermometer USES. A thermometer is an instrument of temperature measurement of high precision. Depending on the temperature measurement of material of different and different temperature range, with kerosene thermometer, alcohol thermometer, mercury thermometer, gas thermometer, resistance thermometer, thermocouple thermometer? Thermometer, radiation thermometer and light, bimetallic thermometer, etc. Depending on the purpose, has been designed and manufactured a variety of thermometer. The basis of its design are: the use of solid, liquid and gas is influenced by temperature and heat bilges cold shrink phenomenon; Under the condition of constant volume, gas ( Or steam) The pressure due to different temperature change; The role of thermoelectric effect; The change of resistance with temperature changes; The influence of thermal radiation, etc. Generally speaking, any physical properties of all matter, as long as it along with the change of temperature and drab, significant changes in, and made available to signal temperature thermometer. On soil temperature and humidity monitoring and recording, we should fully consider the monitoring and recording the environmental influence on the result, so using the soil thermometer, when determining the soil humidity, focusing on agriculture, forestry and animal husbandry, agriculture is the first, at the same time balancing the needs of Lin Muye, in addition to the soil moisture rich zone, northeast plain, the agricultural region on the loess plateau in the huang-huai-hai plain and has more stations, which are some grain and cash crops, mostly in the form of national soil moisture station county. In pastoral areas and forest were also set up a certain number of soil moisture and soil temperature, it makes the soil moisture data can provide better service for agriculture, forestry and animal husbandry production. Soil thermometer can be widely used in agriculture, soil moisture monitoring system, standard fertile land project, smart irrigation control project, soil moisture and satellite remote sensing monitoring system's monitoring system, real-time monitoring system of soil moisture, geological exploration, plant breeding and other fields, play a crucial role.
