| Abstract: |
| ［Purpose］This paper introduces the development and application of the Maize Nutrition Expert System：a computer software system for guiding the application of maize fertilizer. ［Method］The development of the Maize Nutrient Expert System is based on a large number of field trial data. The QUEFTS model is used to simulate the optimal nutrient uptake of maize under different ecological conditions，according to the relationship between yield response and agronomic efficiency，and the soil nutrient balance. The best fertilization amount is recommended under different conditions，which would optimize the field management measures. This paper finally summarizes the characteristics，principles，development history and field application effects of the software.［Result/Conclusion］The software was developed by the International Plant Nutrition Institute（IPNI）. Since it is introduced in China in 2009，it has been upgraded and re-edited many times. From the initial computer version，it has launched the online version of the webpage，smart phone WeChat version，etc. After years of field trials，the results show that comparing to farmers’ traditional fertilization，the software can achieve more accurate fertilization recommendations，reduce fertilizer input，and increase maize planting production income. Therefore the software has good application prospects. With the continuous integration of artificial intelligence and Internet technology，the operation of“ Maize Nutrient Expert System” will be more convenient and accurate，with good application and development prospects. |
