On the 30th, in the 265th "China Engineering Science and Technology Forum - Smart Agriculture Forum" closed in Beijing, Wu Wenbin, a researcher at the Institute of Agricultural Resources and Agricultural Regional Planning of the Chinese Academy of Agricultural Sciences, gave a title titled "Wisdom Agricultural Applications Driven by Sky and Big Data". Depicting the emerging and upcoming agricultural 4.0 era, through the integrated information gathering technology and equipment of the sky, the full resource elements of agriculture, the whole production process, full-time position perception, diagnosis, decision-making, thus achieving accurate planting and A beautiful picture of intelligent management.
Wu Wenbin said that agriculture has experienced four stages of development, namely, agricultural 1.0, the traditional agricultural stage with manpower and animal power as the main means of production; agriculture 2.0, the mechanized agricultural stage with agricultural machinery as the means of production and tools; Application of hybrids, extensive use of chemical fertilizers and pesticides to improve the level of agricultural production in the bio-chemical agriculture stage; Agriculture 4.0, information-based production elements, Internet, Internet of Things, big data, cloud computing, automation, intelligent robot applications stage.
He explained that the key technology of integrated agricultural information gathering in the field of agriculture in the era of agriculture 4.0, the sky, that is, space remote sensing observation, has the characteristics of large-scale and spatial continuity, composed of space, hyperspectral, microwave, lidar, etc.; That is, aerial remote sensing observation, with high precision and time continuity, consists of optical, multi-spectral, thermal infrared, laser, etc.; ground, ie ground-based Internet of Things observation, with high frequency, real-time observation characteristics, by environment and crop sensors, video , farmers' perceptions and other components. Realize perception through sky-integrated information gathering technology and equipment, including large data (multi-dimensional information) of farmland plots: physical information such as location, shape and area, ecological environment, planting type, input and output, and farmers' main attributes; Diagnosis, including dynamic monitoring of time and space, diagnosis, analysis, prediction; decision making, namely precision planting and intelligent management.
