A PRELIMINARY STUDY ON THE APPLICATION OF CROP SIMULATION MODELS IN AGROMETEOROLOGICAL SERVICES

Aimed at the requirement of agrometeorological services and based on meteorological data and crop data in 1961—2000 in 5 typical meteorological stations, the impact of regional meteorological condition on maize growth and development was assessed by using crop model. The method of calculating average simulated biomass as evaluation standards under average climate condition was studied. The resolution to real-time dynamic evaluating and evaluation summary for agrometeorological conditions during crop growing season was proposed, including change in biomass and effects of temperature and soil moisture. Several case studies were presented. The validation results show that the method is satisfied.
