The range of accumulated temperature ≥ 10℃ is 1800 ~ 2800℃, and the accumulated temperature decreases about 1 00℃ with the increase of latitude in plain area; For every increase of 100 m in mountainous area, the accumulated temperature decreases 100℃ ~ 170℃. The frost-free period in the whole province is between 100 ~ 150 days, and between 140 ~ 150 days in the south and east.
