Scientific and technological innovation is the main theme of the future development of various industries, and agriculture is no exception. Then, how to apply science and technology to agriculture and provide a strong driving force for the high-quality development of agriculture?

Introduction to two technologies of smart agriculture

1、 Sensor technology

Agricultural sensors mainly include soil sensors and environmental sensors.

The soil sensor is used to detect the soil temperature, moisture and the content of nitrogen, phosphorus, potassium and other elements in the soil during plant growth, and digitize the soil environmental factors, so as to analyze the plant growth status. Environmental sensors are mainly used to monitor and analyze the environment where plants grow, such as water, soil and air, so as to timely understand environmental changes and ensure that plant growth and crop quality reach a high level. At present, the commonly used agricultural sensors mainly include temperature sensor, humidity sensor, pH sensor, gas sensor, biosensor, photoelectric sensor and pressure sensor.

2、 Internet of things technology

The difference between intelligent agricultural system and traditional agricultural system lies in the application of Internet of things technology.

Internet of things technology is the third revolution of information technology industry. Internet of things refers to connecting any object with the network through information sensing equipment and according to the agreed protocol. Objects exchange and communicate information through information media, so as to realize the functions of intelligent identification, positioning, tracking, supervision and so on.

The combination of Internet of things technology and sensor technology, the use of sensors and computer platform software, is a good connection between traditional agriculture and modern science and technology. Intelligent management such as visual remote diagnosis, remote control and disaster early warning can be realized through the Internet of things technology. The parameters such as temperature, humidity, light and CO2 concentration of the agricultural production site can be collected in real time through wireless sensors, and the agricultural production environment can be monitored remotely. At the same time, the collected parameters and information can be converted and summarized digitally and transmitted in real time through the transmission network, Upload to the relevant agricultural intelligent management system to effectively and continuously monitor the crop growth environment and drive the motor and other equipment to implement corresponding measures for the environment.

3、 Application scenarios of smart agriculture

Application of Intelligent Agriculture in field

Through the comprehensive application of sensor technology and Internet of things technology, smart agriculture supervises the growth of crops and soil quality, and uploads the detection report to the Internet system at any time. Through its intelligent analysis, we can accurately adjust according to the growth of crops and ensure the yield and quality of crops.

The role of smart agriculture in Greenhouse

Due to the growing popularity of off-season vegetables, greenhouse vegetables have been planted in many areas of many provinces. The application of Intelligent Agriculture in greenhouse is also a new form of agriculture. The system digitally and informatizes the growth process of vegetables in greenhouse through sensors such as soil temperature, humidity and light, so as to ensure the normal growth of vegetables, It also ensures that its process color, environmental protection and organic production can systematically manage greenhouse vegetables, ensure market supply and alleviate the tension of vegetable supply in China.

Introduction to two technologies of smart agriculture

The advancement of China's agricultural modernization is closely related to science and technology. As an important force of agricultural informatization, the Internet of things and sensor technology in smart agriculture have been highly valued and studied by all walks of life. The comprehensive application of sensor technology and Internet of things technology can not only improve labor productivity and land utilization, but also change the labor mode and management method of agricultural production, so as to promote agricultural informatization and agricultural modernization.
