The only way to improve the quality and efficiency of Agriculture

At present, China is in the process of changing from traditional agriculture to modern agriculture, and information technology has become an important way to transform traditional agriculture by using modern high and new technology. The development of agricultural informatization has roughly experienced four stages: computer agriculture, digital agriculture, precision agriculture and intelligent agriculture. Intelligent agriculture is an advanced stage of agricultural production, which integrates emerging technologies such as the Internet of things, big data, cloud computing and so on. The Internet of things is an extension and expansion on the basis of the Internet, through comprehensive perception, the Internet of everything and intelligent applications, to achieve the connection between things and things, things and people, all things and the network, so as to identify, manage and control. In China, the application of the Internet of things in agriculture has shown certain results, promoting the rapid development of agriculture in many aspects, such as greenhouse vegetables, field cultivation, flower cultivation, aquaculture and so on. Agricultural Internet of things related technologies, systems and products have been preliminarily applied in the field of agricultural and rural informatization in China. For example, common sensing technology, intelligent management system, remote sensing system, remote monitoring system, biological information and diagnosis system and so on. These technologies help to supervise the whole production and circulation process of agricultural products, and transfer the relevant information of each link to the database of agricultural products circulation center with the help of the Internet of things, which improves the level of safety and quality management of agricultural products and the effectiveness of logistics.

The research and application of agricultural Internet of things technology is not only the need of the development of modern intelligent agriculture, but also an important symbol to measure a country's comprehensive scientific and technological strength and agricultural development level. At present, while China's agriculture has made great achievements, it is also faced with severe challenges such as the increase of population, the reduction of cultivated land, the reduction of rural labor force, the increase of natural disasters, the aggravation of environmental pollution and so on. Therefore, the future agricultural production needs accurate monitoring and scientific management to achieve the rational allocation of resources, to achieve the maximum income with the least investment, to make efficient use of all kinds of agricultural resources, and to achieve the maximum economic and environmental benefits. In the future, the Internet of things in agriculture should meet the needs of intensive, high-yield, high-efficiency, ecological and safe development of modern agriculture. comprehensive use of wireless sensor technology, mobile communication technology, automation technology, crop safety production and efficient cultivation technology, integrated pest control technology, efficient utilization of soil fertilizer resources, etc. To achieve the goals of accurate monitoring of environmental information, accurate management of production process, intelligent implementation of fertilizer, water and medicine, intelligent diagnosis and early warning of diseases and insect pests, and supervision and traceability of agricultural products quality and safety under the support of interdisciplinary and multi-field high-tech comprehensive application. With the extensive application of sensor terminal equipment in agricultural production environment, agricultural production environment variables are converted into digital signals for transmission, storage, analysis and processing, and the amount of data is gradually becoming larger and larger. Under the environment of big data, the Internet of things technology such as comprehensive perception, reliable transmission and intelligent processing has innovated the application mode of the Internet of things in agriculture, and the utilization efficiency of various agricultural resources has been greatly improved. The energy consumption and cost of agriculture will be reduced to the maximum, the damage to the agricultural ecological environment will be reduced to the maximum, and the degree of intelligence and generalization of the whole chain, industry and process of agriculture will be improved. the realization of real-time monitoring, automatic control and digital management of agricultural production environment, and the overall optimization of agricultural production management system is also the inevitable trend of the development of agricultural Internet of things in the future.

Agricultural Internet of things through the effective combination of information technology to achieve a high degree of intelligence is the inevitable trend of China's agricultural development, and the promotion and application of agricultural Internet of things is an important way to achieve this goal. Under the promotion of the government and relevant scientific research institutions, China's agricultural Internet of things technology has made some progress, and its application has achieved good results, but its technology is still far from maturity, and there is still a lot of room for application. The specific performance is as follows: the application object of agriculture in our country has diversified characteristics, and the information collected is also very complex. Although China has played a leading role in the formulation of international standards for the Internet of things, there is no unified and effective standard system in China. The corresponding business model of the Internet of things in agriculture is not yet mature, the problem of repeated investment is more prominent, and the business model of sustainable development is less. In the future development, we should actively explore different kinds of agricultural products, different types of agricultural production and management main bodies of agricultural Internet of things technology application model and sustainable business model. In China, the refinement and automation of agricultural production is still relatively weak, and the popularization rate of existing agricultural monitoring and automatic control technology is low, which restricts the development of the application of agricultural Internet of things. The hardware equipment and technical level still need to be improved. In the future, we should strengthen the attention and research on the agricultural Internet of things, constantly improve the construction of its standard system and operating mechanism, and promote the standardization, scale and industrialization of the application of the agricultural Internet of things.
