胶东丘陵区冬小麦生育期低温冷害预警模型研究
Study on Early Warning Model of Low Temperature and Cold Damage during Growth Period of Winter Wheat in Jiaodong Hills Area of Shandong Province
摘要
Abstract
Based on the data of winter wheat yield and temperature during growth period in 30 years from 1979 to 2009, the variation rules of mean temperature in a period often days and its relationship with relative meteorological production were analyzed to make sure the probable low - temperature risk appeared during the growth period of winter wheat. The results showed that the mean temperature of the middle ten days of January and the first ten days of March affected the relative meteorological production significantly with the correlation coefficient as -0.44 and 0.37 respectively. There were 5 temperature factors in the warning model, and the significance of the model reached 0.01 level.关键词
