The Study Of Intelligent Agriculture Information Technique And Its Demonstration & Application Modes

Agriculture is the base of the national economic. Since the reform and opening policy carried out, Chinese agriculture has been well developed in past 20 years. Managemental method reforms such as application of cooperative contacting & liability productive system, accompanied by the advancement of agricultural technique and equipments, which both inspire the peasant' enthusiasm, accelerate the development of the agriculture. Agricultural production shortage problem has been resolved in china by now, and a new agricultural quantitative productive pattern is also formed, which guarantees the national economic going up healthily. However, compared with the advance agriculture productive patterns, China is still laid behind, such as; outdate technique means, low product quality and coexisting of relative overplus and shortage outputs. After affiliating to the WTO, facing the worldwide competitions, how to develop the agriculture production is the key to construct Xiaokang society, secure national agriculture and stable the economic basis. By using information technique, i.e. intelligent agricultural techniques, agriculture can be guide to qualitative development mode with an improved overall technical level and competitive edge.China is one of the pioneering countries in the study the intelligent agriculture expert system. It began as early as I980s'.since then; much research work and trial applications have been done. In 1990s', sponsored by national science and technology agency and "863-306" project group, most provinces have carried out the demonstration and application research of intelligent agriculture expert system. Today 23 demonstrating and application areas are covered 19 provinces. Because of the different regional natural, economic and social conditions, no two demonstrating modes selected by them are same. Based on the definition and research category of agricultural information, this paper analyzes and designs the structure, function and the developmental method of agricultural expert system, summarizes the previous successful experiences and its disadvantages both abroad and home. On the ground of investigating and analyzing the practicing process of national intelligent agricultural demonstrating project "863-11", the essay also raises the several different demonstrating and application modes under the different agricultural productive and technical conditions, such modes as "state farm +family farm", "agriculture related enterprise + government + fanner", "national technique spreading system+government+farmer", analyses the applying conditions of every mode. Finally, the essay also discusses the deficiency existed in practical demonstrating experience and its countermeasures, and provides theoretic and practical guide for further development..
