| 摘 要： | 利用呼和浩特1971—2007年气象资料与1988—2007年物候资料,分析了玉米适宜播种期与春季树木物候期的相互关系。结果表明:春季树木物候期与气温存在很好的相关性,用冬春季气温预报春季树木物候期,再由树木物候期确定玉米适播期,或用树木已出现的物候期预测下一个物候期,从而预报玉米适播期等方法均取得较好的预报效果。

| Abstract: | Using the meteorological data from 1971 to 2007 years and phenological period data from 1988 to 2007 years in Hohhot,the correlations between the sowing period of corn and the phonological period of trees in spring was analyzed.The results showed that phonological period of trees in spring had a strong relativity with temperature.It was able to use temperature of Winter and Spring to forecast phonological period of trees in Spring,then to forecast sowing period of corn,or use front phonological period to fo... |
