黑龙江省玉米产量预报模式的研究

A Study on Forecast Model for Maize Climate Yield in Heilongjiang Province

通过对玉米生长过程的干物质累积曲线进行逐时段的温度和水分订正,建立了黑龙江省玉米气候产量的预测模式,为玉米产量预报提供了科学依据。

A forecast model for maize climate yield in the Heilongjiang Province was established, through modifying the curve of accumulated dry matter of maize by temperature and water demands for each growing period. The model provided a scientific base for predicting maize yields in the Heilongjiang Province.
