摘要: 通过分析辽宁省玉米热量指数分布情况,为辽宁省玉米延迟型低温冷害的预测提供基础方法。利用1961—2010 年的逐旬气温资料、作物发育期数据和大气环流资料,建立了分区域玉米热量指数的滚动预测模型。结果表明:辽东、辽南、辽西、辽北及中部地区2000—2010 年的预测数据与实况数据相关系数分别为97.3%、95.4%、98.2%、97.5%、98.5%。模型的准确率较高,且稳定性较好,能较为准确地预测辽宁省玉米生长发育期间的热量状况。

Abstract: In this study, Using the average temperature of ten days from 1961 to 2010, the corn heat indexes in Liaoning province are calculated. Based on the statistic analysis between heat index and atmospheric circulation data, the forecasting models the corn heat index is developed. The results show that the correlation coefficients between the predicted and observed values of heat index in these 5 corn-growing regions that is the east Liaoning, the south Liaoning, the west Liaoning, the north Liaoning and the Central Region during the period from 2000 to 2010 are 97.3%,95.4%,98.2%,97.5% and 98.5% respectively. The model can be used to forecast heat status in the growth and development period of corn in Liaoning province.
