Soil is the basic environment on which plants depend. Therefore, the quality of soil is directly related to the growth of plants, which in turn affects the yield and quality of crops. In soil quality, the most important concern in the past was soil moisture, because plant growth was inseparable from water, and plant moisture was mainly obtained from soil, but the relationship to soil temperature was often insufficient, and in fact, attention was paid to ground temperature regulation. , It is also one of the important measures to effectively improve the crop cultivation efficiency. The following takes the measurement results of the ground temperature thermometer as an example to explain why we must pay attention to the temperature regulation.
Geothermal thermometer is a professional instrument for measuring soil temperature. A large number of measurements and studies have shown that ground temperature is closely related to the growth of plant roots. With the decrease of temperature, the vitality of the root system is increasingly limited, and the cold resistance of the roots determines the growth force. Key factor. When the temperature dropped to 10°C in the local area, the root activity dropped by 70-80%, and the crop would have insufficient supply of fertilizer and water. The disease manifested as increased disease, especially as systemic diseases increased, and growth was slow and poor. When the ground temperature drops to 5°C, the basic function of the root system will be lost, and the crop will have a shortage of fertilizer and water in a large area, manifesting as aggravation of the disease and systematic diseases or full-scale outbreaks, which will cause irreversible effects on crop yield and quality. This shows that the management of ground temperature is of great significance for crop roots and growth.
During the period from late autumn to winter, the ground temperature is generally low, and it is very easy to cause low-temperature damage to crops in this period. Therefore, it is necessary to pay special attention to the regulation of ground temperature during this period. We recommend that professional ground temperature thermometers be used to monitor ground temperature, perform scientific low-temperature control, and monitor and control the effects. For ground temperature management, the main methods that can be adopted include: raising ground temperature, adopting membrane or heating measures; avoiding cooling, less watering or not watering; strengthening insulation, taking measures to improve the insulation performance of the back wall, and improving the roots of crops Ability and so on.
