Abstract Based on the analysis of heat resources in Shuangyashan City， the trend of climate warming in recent decades was analyzed， and suggestions were put forward to make rational use of heat resources， and timely and early sowing to capture accumulated temperature; According to the analysis of the correlation between the natural phenology “poplar sprout” and the field sowing date， the index of early sowing of field crops at the beginning of poplar sprout was found， the prediction equation was established， and the reliable and objective sowing time was calculated， so as to make full use of the local temperature resources and improve the yield per unit area.

Key words Heat resources; Early sowing; Suitable sowing time
