The significance of the existence of instruments for measuring soil temperature

Plant roots are the main part of absorbing nutrients.
There are many factors that affect the growth of crop roots, and soil temperature is one of them
.

The soil temperature that affects crop root growth refers to the soil temperature in the shallow subsurface
.

Soil temperature is closely related to crop root growth
.

One is the effect on root metabolism, and the other is the effect on root soil ecology
.

First, let's talk about the relationship between soil temperature and crop root growth, and the relationship between root metabolism
.

Roots need to breathe
.

Low soil temperature inhibits respiration, while proper soil temperature enhances root respiration
.

Water conductivity and active nutrient transport decreased significantly when the root system was at a lower root temperature
.

Root zone temperature affects the synthesis, content and activity of substances in roots
.

In addition to substances such as malondialdehyde and soluble sugar (sucrose), crop roots also contain a variety of enzymes, such as catalase, peroxidase and superoxide dismutase
.

These substances are related to the nutrient composition (sugar content, water content), respiration, stress and disease resistance of crops
.

　　Second, the effect of soil temperature on root zone ecology
.

Microbes in the root zone are very rich, and they are no less sensitive to temperature than the root system
.

Their role in the soil is to break down organic matter, transforming nutrients that plants can take up
.

Low temperature in the root zone will affect their activity and inhibit their biological enzyme activity
.

The root zone temperature affects the pH value of the root zone soil, which directly affects the soil environment and crop growth
.

　　To sum up, the soil temperature around the root system of crops can measure the growth of plants, so it is necessary to use a soil temperature tester when measuring the soil temperature.
The soil tester was developed for this important work, which can quickly measure the soil temperature.
temperature, providing data support for plant protection and agricultural production
.


The soil moisture temperature rapid measuring instrument is a scientific instrument used in modern agriculture
.

It is mainly used to measure the soil moisture of each soil layer, realize continuous and automatic observation, and upload the collected data through GPRS communication technology, so as to facilitate the technical study of soil moisture changes and guide agricultural irrigation more scientifically and effectively
.

Compared with the traditional soil observation methods in the past, the GPS soil moisture rapid measuring instrument has the characteristics of high measurement accuracy, fast speed, wide range, portability and convenient maintenance
.

Being able to understand the continuous changes of soil moisture and the degree of soil "thirst" in a timely manner, improve the timeliness of soil moisture monitoring data, and play an important role in judging whether the current soil moisture meets the normal needs of crop growth
.

　　The soil moisture and temperature rapid measuring instrument uses the power of science and technology to serve "agriculture, rural areas and farmers", realizes the transformation of soil moisture observation from traditional manual observation to automatic observation, and injects scientific and technological power into the further promotion of "agriculture, rural areas, and farmers"
