Significance of intelligent agriculture

China is a big agricultural country, not a strong agricultural country. In recent 30 years, the high yield of orchards mainly depends on a large number of inputs of pesticides and fertilizers. Most fertilizers and water resources are not effectively used and discarded everywhere, resulting in a large number of nutrient loss and environmental pollution. China's agricultural production is still dominated by traditional production methods, and traditional farming can only rely on empirical fertilization and irrigation, which not only wastes a lot of manpower and material resources, but also poses a serious threat to environmental protection and soil and water conservation and poses a severe challenge to the sustainable development of agriculture. In view of the above problems, this project uses the real-time and dynamic agricultural Internet of Things information collection system to realize the rapid, multi-dimensional and multi-scale real-time monitoring of orchard information, and on the basis of informationization and planting expert knowledge system, it realizes the automatic control of intelligent irrigation, intelligent fertilization and intelligent spraying of farmland. Break through the bottleneck of technical development such as difficulty in obtaining orchard information and low intelligence.

At present, most fruit production in China mainly relies on artificial experience and special management, lacking systematic scientific guidance. The development of protected cultivation technology has a far-reaching impact on the process of agricultural modernization. Protected cultivation has played an important role in solving the consumption structure of urban and rural residents, increasing farmers' income and promoting the adjustment of agricultural structure. Greenhouse cultivation has played an important role in agricultural production. Information acquisition is one of the most important key technologies to realize high-level facility agricultural production and optimize facility biological environment control. As the high integration of three foundations of modern information technology (sensor technology, communication technology and computer technology), wireless sensor network is a brand-new information acquisition and processing technology. The network consists of a large number of intelligent sensor nodes with low energy and low power consumption. It can work together to monitor, perceive and collect the information of various environments or monitored objects in real time, and process it to obtain detailed and accurate information, which is transmitted to the base station host and users who need this information through the wireless transmission network. At the same time, users can also transmit instructions to the target node through the network, so that it can perform specific tasks.
