Developing precision agriculture is a core part of digital agriculture

The development of precision agriculture is a core part of digital agriculture. As a new concept of digital, information and knowledge management of agricultural production system, the practical application of precision agriculture will be revolutionary for promoting the application of modern digital technology and information technology to transform and upgrade traditional agricultural science and technology and agricultural equipment technology, advocating new ideas of scientific management and operation of agricultural production process, and achieving leapfrog and sustainable development of agriculture.

Precision agriculture is mainly the use of modern digital technology, information technology, agricultural high technology and the scientific combination of the three, dedicated to the efficient use of agricultural resources, improve output, save inputs, reduce costs and increase efficiency, adopt high technology, improve productivity, reduce environmental pollution, implement sustainable development, adapt to today's establishment of agricultural products quality assurance and food chain safety production tracking and product safety certification technology The new requirements of the food safety system and the safe production of food.

It mainly carries out integrated innovation of science and technology such as agricultural application of geospatial information technology, advanced sensing technology for rapid collection of spatial distribution information of farmland and efficient real-time information processing technology, decision support technology for refined management of farmland soil and crop production, intelligent variable operation and agricultural equipment technology and system integration and analysis technology.

Precision agriculture includes not only the application of geographic information system (GIS) technology to map out the distribution of elements (such as soil nutrients, soil moisture, the number and severity of pests and weeds, etc.) within a field, and agricultural machinery adjusts its operation according to the size of the element values in the map;.

Moreover, when the agricultural machinery operates in the field, it applies sensors to directly measure the element values, and at the same time automatically determines the amount of fertilizer application and drug application, etc. through the agricultural model, and then the agricultural machinery automatically adjusts the operation.

In this way, the amount of fertilizer, irrigation, medication and other operations are more accurate, and can simultaneously achieve high yield, high quality, high efficiency, and minimize pollution to the environment. Precision agriculture requires the integration of a series of modern high technologies, and China is still in the initial stage of exploring the practice of precision agriculture, therefore, it is necessary to establish experimental bases to improve the integration and demonstration of precision agricultural production technologies.
