| In north agricultural facilities, greenhouse and it's production are main items for agriculture development zone. The region and scale of greenhouse are large and it's standard is high. Through research and development to greenhouse shed many years, it's structure is gradually ripe and it's standard is higher. Greenhouse is developing to plant rare breed of crops with high benefit and quality. There are many questions for example low science technique content fall behind management means and low unit economic benefit etc. About today greenhouse shed with the rapid development of accurate and control agriculture. In the condition about high temperature and damp many cloudy rain and snow, the environment of greenhouse can't be controlled effectively because of fall behind management equipment and means. So there are huge economic loss greenhouse production. Since under the condition of normal weather, how to make use of modern and high new technique and measures adjusting to control the glasshouse environment and water automatically fatty, how to feat growth environment of the construction farm crop, how to improve farm crop quality and adjust to control the farm crop growth especially the time of valuable species, valuable flower to appear on market, making sure they appear on market properly to the season, are the key technique problem and needing the actual production and controlling problems which could raise the economic performance of the glasshouse production and make glasshouse production keeping on the fast development and having the delay effect of development, with the development of glasshouse production's scientific, modernize and intensive management, this antinomy will gradually outstand. For this, studying the suitable glasshouse structure and state of nation for our country, constructing the feat glasshouse production environment, raising the unit glasshouse environment's economic performance of intelligent supervision system, are the currently medium demanding practical technique in agriculture production, having vast market needs. With the rapid development of country economy and constant increase of farmers income, increasing investment to agricultural facilities and regulating agricultural planting structure improve standard of greenhouse construction and maturate gradually the research on shed structure. However, the research on scientific management means and measures cannot keep up with the development of shed structure. Especially, with the improvement in shed standard and increase in investment, it is required to plant rare breed of crops with high benefit and quality, to have better production management and growth environment including advanced scientific management measures and means.With the development of science and technology, especially the wide application of computer technology, a big technical problems demanding prompt solution rises, that is, how to use fully computer technology to inspect and control shed environment automatically, to create a good environment for crops growth, to collect environmental data in time and correctly to do real-time calculation on possibility of plant diseases and insect pests, and to establish necessary synthetic protection mode.In the light of actual greenhouse production in area of 38 -42 latitude in China, this research applies computer technology to the supervision and control of greenhouse environment and gets the following important technological achievements:1. Have established integrative assemblage of automatic supervision and control system in sunlight greenhouse environment that is suited to Chinese national conditions;2. Have established mid and short term real-time calculation model and synthetic prevention and cure model to cope with plant diseases and insect pests;3. Have established integrative production management mode on greenhouse environment including automatic supervision and control technology, irrigation technology, calculation and forecast techno1ogy and synthetic prevention and cure techn...
