1. Priority research in the implementation of "precision agriculture" Research and development of new-generation agricultural machinery and equipment technology, and research and development of information technology-based crop production management decision support systems, etc., have been "accurate agriculture" for nearly six or seven years. Technology has made it possible to enter important conditions for increasingly extensive experimental practice. Today, several important agricultural machines supporting “precision agricultureâ€, such as grain combine harvesters for automatic harvesting of wheat, corn and soybeans with yield maps, and grain precision seeders, fertilizer applicators, and pesticides for variable-prescription farming Machines and irrigation equipment have already existed in some types of commercial products abroad, but they need to continue to be perfected and extended to more fields for agricultural machinery operations. In recent years, several developed countries have begun research on yield measuring sensors for harvesting machinery such as cotton, sugar beets, potatoes, rice, sugar cane, pasture, and fruits. The results of relevant experimental studies have been reported at the International Conference on Precision Agriculture and important publications. Research prototype has entered the test application. According to the social and economic conditions of different countries and regions, the application of “precision agriculture†can focus on improving production, cost-saving and environmental protection, adopting different technology assembly methods, and gradually improving the scientific and detailed production management of crops. Level. Among them, the establishment of a complete precision agricultural technology system requires the integration of multiple technical knowledge and advanced technical equipment, which provides agricultural machinery engineers with opportunities for technological innovation. Studying the agricultural machinery equipment and planting characteristics suitable for different countries, and adapting to different crops and more precise intelligent technologies of the above-mentioned links are still challenges faced by agricultural machinery engineers. The demonstration experiment of “precision agriculture†has become an important entry point for applying information and high technology to achieve technological innovation in agricultural machinery. The following topics can be used as a priority area for promoting innovation in agricultural machinery and equipment.

2. Science and technology issues that need urgent research in the study of "precise agriculture" Because crop production is affected by many factors, the fine management of current crop production is based on the analysis of information on the distribution characteristics of the community to formulate prescription management decisions. Crop yield is the result of comprehensive effects of many natural environmental factors and planting and management levels. Therefore, obtaining the differential information of crop yields and spatial distribution in the farmland area is the key to the practice of precision agriculture. With the harvesting machinery output measurement equipment and the plot production map production system, farmers can analyze the causes of differences in output and community output according to their own experience and knowledge, select economically applicable countermeasures, and take appropriate measures to implement regulation under realistic and feasible conditions. . According to the conditions of technical and economic development, the use of advanced scientific and technological means or intelligent variable prescriptions can also be used to automate the process of agricultural machinery production. To study the real-time measurement of production and the automatic generation of production maps in the "precision agriculture" system, the following scientific and technological issues need to be resolved.
(1) Further improvement in measurement accuracy, stability, versatility, and ease of calibration of the flow sensor.
(2) In the output measurement, the water content of the harvested product, the actual cutting width and the forward speed of the harvester are also obtained.
(3) The production yield map technology and its required spatial resolution are not greater than the DGPS positioning system for harvesting machine work width.
(4) A grain transport process model for the grain from the header to the flow measurement point was established for different harvesting machines to correct the dynamic error of the production distribution information.
(5) Study the location data and production data coding format and fast storage transmission method. These data are usually stored on a floppy disk or smart card, can store all the data in at least one job class at a time, and then they are sent to the PC for processing and production yield maps.
(6) Develop software based on PCs and PDAs that can generate yield maps, including file structure, data structure, error correction, data visualization, and display methods.
The grain combine harvester electronic device, including the automatic measurement of grain output and the automatic generation of production volume maps, is an important direction for contemporary agricultural machinery research and should also be one of the priorities for the development of mechanical and electrical integration and informatization research of agricultural machinery and equipment in China. The importance of improving the informationization awareness of agricultural operations, promoting scientific management of crop production, and supporting the improvement of the scientific and technological level of services for ex situ harvesting and the socialization of farm machinery have important practical significance and demonstration functions. It should be an important innovation in China's agricultural machinery technology in the new century. Question.
