"Wheat corn intelligent decision system" passed the appraisal in Beijing

Introduction: a "wheat corn continuous cropping intelligent decision system" which can simulate, monitor and predict the whole production process of crop planting, growth, quality and yield by computer has passed the expert appraisal in Beijing recently This intelligent decision-making system, which is presided over by researcher Zhu Yeping of the scientific and technological documentation center of the Chinese Academy of Agricultural Sciences, uses artificial intelligence technology, network technology, simulation visualization technology and database technology to analyze the utilization of agricultural resources in these two major crop areas, reasonably mix the items, select the sowing date, and optimize the management of water and fertilizer; system application system dynamics principle and Simulation Technology For the first time, the model of wheat corn continuous cropping system is established and its application environment is developed The users can see the simulation working environment and state on the computer and network, and can call it remotely The system integrates fuzzy logic, genetic algorithm and artificial neural network technology, and develops a data modeling tool, which can predict crop production intelligently The system applies multimedia technology, The knowledge base of wheat and corn production management was established By using this system, input the given data of wheat, corn variety, soil, weather and experience water and fertilizer, select the management mode, run the single cropping or continuous cropping model, and then get the daily value and visual curve of yield, character, plant, soil and climate, and the utilization of water and nitrogen; after inputting the correlation coefficient, we can get the limited irrigation amount and irrigation The system can monitor the growth and development of wheat and corn; after selecting the decision-making objectives of maximum yield, maximum net income, and maximum yield ratio, the best variety combination and planting scheme of continuous cropping can be obtained according to different varieties and fertilizers to realize intelligent decision-making It is reported that this system has been applied in Beijing, Hebei and other places The English version of the system has been exported to Namibia.
