The active accumulated temperature of 0.0°C is 5299°C, which is higher than the counties in Huaibei and second only to the Jianghuai region.

Generally, the two-cropping system can be implemented when the accumulated temperature is above 0.0℃ and above 4600℃. Therefore, from the perspective of crop growth needs, the heat conditions in Sihong County are very sufficient to meet the annual two-cropping system of wheat-rice.

?Climate characteristics: Sihong County is located in the transition area from the warm temperate semi-humid climate zone to the subtropical humid climate zone, and has transitional and monsoon climate characteristics.

The monsoon is significant, the four seasons are distinct, the rainfall is concentrated, the rain and heat are in the same season, the spring is warm and changeable, the autumn is crisp, the light is sufficient, and the heat is abundant.

Sihong is located on the west bank of Hongze Lake, where winds from east to southeast prevail in summer and autumn.

The air is humid, and there are 7 rivers in the territory flowing into Hongze Lake, forming a unique natural microclimate.

Because it is located on the west bank of Hongze Lake, the terrain is low-lying, mostly clay soil, with good water retention properties. In addition, the groundwater level is high and the soil moisture is sufficient, so the probability of drought is low, which is conducive to the growth of later rice and old-age rice.
