The effect of soil temperature on plant roots

User:JXCTUpload time:Sep 26 2021
Effects on root physiological metabolism:

First of all, there is a close relationship between soil temperature and root respiration. Studies have shown that low root zone temperature inhibits root respiration and ultimately leads to nutrient absorption and root growth are affected; and in low temperature environments. With the increase of root zone temperature, root respiration will gradually increase. Secondly, soil temperature is a key factor affecting root nutrients and water absorption.

Even small changes in root zone temperature can cause changes in root nutrient absorption. When the root system is in a low root temperature environment. Water conductivity and active nutrient transport are significantly reduced. Finally, soil temperature will affect the synthesis, content and activity of the substances in the root system. The roots of crops contain a variety of enzymes. Such as catalase, peroxidase and superoxide dismutase. In addition, it also contains other substances, such as malondialdehyde, soluble sugar (sucrose) and so on. And these substances and the nutritional composition of crops (sugar content, moisture). Respiration, stress resistance and disease resistance are all related.

Soil temperature is closely related to plant growth. Warmth induces vegetation development in terms of water and nutrient absorption and overall plant growth. Low temperature inhibits water absorption due to lower water viscosity and slows down the process of photosynthesis. Therefore, for the growth of crops.

How to monitor:

Early morning is the best time to monitor the temperature. The soil may warm up later in the day, but you need to know that your seeds will experience the coldest temperatures. Sowing in soil that is too cold will prevent germination and your seeds may rot. To measure temperature, a soil temperature and humidity sensor is required. Insert the sensor into the soil to get the temperature and humidity conditions. Like water and fertility, it plays an important role in controlling plant growth. Plant species have different temperature requirements. You can monitor the temperature at the site to show when you start to restrict plant growth.
