摘　　要：气温的变化是不可避免地引起土壤温度的变化,所以从气温的变化规律可以预测浅层土壤温度的趋势。东北气候四季分明作物生长只有一季,春季气温的变化是掌握作物播种时间的关键因素。The change of temperature inevitably causes the change of soil temperature,so the trend of shallow soil temperature can be predicted from the change law of temperature.There are four distinct seasons in the northeast climate.The change of spring temperature is the key factor to master the sowing time of crops.
