A variable fertilization system was developed and implemented by integration of expert system and crop monitoring models on the basis of the variable of the wheat growing process of LAI.Component object model connected with expert system and the database,wheat growth model base formed a complete system,which offered fertilization guidance for different regions and wheat varieties,including total amount of N,P,K fertilization before sowing and precise N amount after sowing.Field experiments of wheat with variable nitrogen fertilization model were respectively carried out at Research Station of Henan Agricultural University and Agricultural Research Institute of Hebi.The results showed that the system can accommodate the factors of weather,soil and wheat growing,which means a lot for developing precise agriculture in the further.
