strategies for sustainable development in the open, under the guidance of the new direction of agriculture. Crop yields from the point of view, it has a high output value per unit area。 if the greenhouse temperature below the set minimum deviation, the issue of regulation of puter instructions, open the ventilation system。s regulation to be convenient and effective, realizes the greenhouse plete intellectualized control. Therefore, the greenhouse expert control system technology is one kind is quite ideal, the parison to have the career development control mode. Modern largescale greenhouse to achieve intelligent control, puter control system must have natural ventilation system, external shading systems, internal insulation and finish systems, wet curtain / fan forced cooling system, CO2 Air System, micromist system, premium optical system, irrigation / fertilization system, breeding system, topspray system, heating system, plant protection systems, lighting systems, picking systems equipment. As a vector control greenhouse control system from the controller39。s corresponding movement, realizes the greenhouse intellectualized management and the production. The agronomist system has provided one brandnew processing plex agriculture question thinking method and the technological means for us. It can act according to the greenhouse environmental condition and the crops growth condition, applies the suitable knowledge expression and the regularization, the inference decisionmaking leaves most suits the greenhouse environment which the crops grow. Applies the agronomist system in the greenhouse realtime monitoring and the automatic regulation is the greenhouse development new luminescent spot. This control mode both can manifest the inherent laws which the crops grow, the display agronomist39。s control technology the agronomist system and the greenhouse automatic control technology organic synthesis, takes by the greenhouse bined environment factor gathering and the analysis object, through expert system39。s change, involves the inherent laws which with di
