作物长势监测系统在作物产量预测应用中的探讨

A discussion about the crop growth monitoring system in yield forecasting

通过对作物长势监测系统(Crop Growth Monitoring System,CGMS)在黑龙江省四大作物产量预测中的应用进行改进并检验。结果表明,应用CGMS对四大作物(玉米、大豆、水稻、小麦)的系统参数进行分区处理是可行的,解决了用统一的一组参数对复杂气候区域作物生长过程模拟的局限性,提高了CGMS在复杂气候条件下的预测应用效果;并提出了CGMS在应用上存在的问题及今后的研究方向。

The CGMS applications of forecast yields were improved and tested for four chief crops in Heilongjiang Province. The results are better and viable that the system parameters are divided into different areas in CGMS for four chief crops（maize, soybean, rice, wheat）. The restrictions of crop growth simulation can be resolved with a set of united parameters under complicated climate areas; the application effects can be improved;the application problems and future direction of the study are put forward for CGMS.
