东北玉米热量指数预测方法研究(Ⅰ)——热量指数与玉米产量
Study on Forecasting Methods of Corn Heat Index in Northeastern China(Ⅰ)——Heat Index and Corn Yield
摘要
Abstract
The change tendency of corn heat index and its correlation with com yield in different provinces in Northeastern China is calculated and analyzed by using the meteorological data of typical stations in 1961-2005 and corn yield in 3 provinces. The results show that the heat index is of a decreasing tendency in Iiaoning province, because of climate warming. But the heat index indicates an increasing tendency in Jillian and Heilongjiang provinces due to the beneficial influence of climate warming on corn production in Jillian and Heilongjiang provinces. The heat index can fairly reflect the correlation between corn yield and environmental temperature. Therefore, low temperature disaster prediction by com heat index forecast can provide basis for decision making of agricultural disaster prevention and mitigation.关键词
