From the development mode of modern agriculture, we can see the development trend of global agriculture in the future

From the agricultural development model of developed countries, the future trend of global agriculture Internet of things agriculture, big data agriculture, information agriculture, intelligent agriculture... ... with the introduction of agricultural technology in developed countries, these words are gradually known to us, and the agricultural development model in developed countries has become a“Benchmark” for us to learn.

Modern agriculture will replace the traditional agriculture from the traditional agriculture to the modern agriculture transformation process, is the industrial elements into agriculture to replace the traditional elements of the process. It is mainly manifested in the substitution of mechanical operation for animal and manual operation, the substitution of organic fertilizer for chemical fertilizer and other industrial input factors, and the substitution of experience-based agriculture for scientific knowledge and experiment-based agriculture The specialized commodity agriculture replaces the self-production and self-marketing agriculture. There are three main agricultural models in developed countries. The first is the American, Canadian and Australian Mechanised agriculture model, whose primary aim is to increase labour productivity The second is the biotechnology model represented by Japan, the Netherlands, Israel and other countries, the primary aim is to improve the rate of land output; The third is the model of combining Mechanised agriculture and biotechnology, represented by France and Germany. No matter what kind of agricultural model is adopted, all countries have entered a comprehensive agricultural modernization with mechanization, improved seed, chemistry, electrification, information and so on as the main contents.

Information technology has become an important means to improve the level of agricultural modernization agricultural information technology for agricultural producers, managers, managers and researchers to provide a variety of information support and services, has been widely used in all aspects of agriculture. Space Information Technology is an emerging technology that emerged in the 1960s. It mainly includes the theories and technologies of Global Positioning System (GPS) , geographic information system (GIS) and remote sensing (RS) , at the same time the combination of computer technology and communication technology. Agriculture is the earliest and most mature field of applying spatial information technology. Precision Agriculture is a modern agricultural mode of production that combines modern information technology with basic disciplines such as agronomy, geography, ecology, soil science and Plant physiology. Dividing farmland into plots (one plot per square metre or one plot per 100 square metres) or parcels of land in the process of growing, managing and eventually harvesting crops, 3s technology is used to acquire the information of soil, crop growth and epidemic disease in each plot in real time, to diagnose the cause of the spatial difference of crops, and to formulate the corresponding farming measures for different plots, in order to improve the utilization efficiency of water, fertilizer and medicine and reduce the environmental pollution, irrigation, fertilization and spraying are carried out in every district.

Circular agriculture and low-carbon agriculture are important ways to achieve sustainable development of agriculture, it is also an agricultural model that can bring better social, economic and ecological benefits. Many recycling agricultural models have been developed abroad, such as material reuse model, reduce resource input model, waste recycling model, etc. . The development of circular agriculture can promote the efficient flow and utilization of various agricultural resources in crop systems, for example, straw returning to the field, organic fertilizer instead of chemical fertilizer, bio-control of pests and diseases, integrated agriculture and animal husbandry, waste comprehensive utilization, and so on, to achieve energy-saving emission reduction and income increase goals for farmers. Low-carbon agriculture is a kind of agricultural model that can reduce the input of all kinds of resources and carbon emission as far as possible, and it is a sustainable agriculture. The development of low-carbon agriculture is mainly through the rational and more efficient use of fertilizer, water-saving irrigation, energy-saving cultivation, to achieve fertilizer, medicine, water-saving, energy-saving purposes. Industrial Technology is widely used in agriculture, so that the development of agriculture, at the same time, need to invest more and more resources, environmental pollution is more and more serious, such as excessive use of fertilizers, pesticides caused soil pollution, burning straw causes air pollution and the loss of nitrogen, phosphorus and potassium in the soil, large quantities of livestock and poultry excrement cause water pollution, plastic and other wastes from greenhouse agriculture cause pollution to the environment, etc. , it is an inevitable trend to develop circular agriculture and low-carbon agriculture. On the whole, agriculture will pay more attention to the combination of science and Technology and humanities, while improving the level of agricultural science and technology, to ensure the harmony between man and nature.
