仙游县(北纬25°11′～25°43′),气候资源丰富,年平均气温20.2℃,无霜期320天,大于10℃的活动积温7405℃,太阳总辐射量112.3卡/厘米~2年,生理辐射56.2卡/厘米~2年.年日照2015小时.能满足作物三熟高产的需要.7～9月日照时数和太阳辐射量均占全年的34%左右,平均气温28.8℃,有利甘蔗旺长和干物质积累.甘蔗成熟期的11～3月,日平均温小于20℃,温差大于9℃,有利蔗糖的合成与积累.年降雨量1600毫米其中82.3%集中于4～10月.高温与多雨同期.水利条件好,土壤以冲积土为主,偏酸性.对喜温作物的生长发育十分有利.
Xianyou County (latitude 25 ° 11 ’~ 25 ° 43’), rich in climate resources, the annual average temperature of 20.2 ℃, frost-free period of 320 days, greater than 10 ℃ active accumulated temperature of 7405 ℃, the total solar radiation 112.3 cards / cm ~ 2 years , Physiological radiation 56.2 cards / cm ~ 2 years. Year of the sun 2015 hours. To meet the needs of crop three high yield .7 to September sunshine hours and the amount of solar radiation accounts for about 34% of the year, the average temperature of 28.8 ℃, Favorable sugar cane flourishing and dry matter accumulation.The sugar cane maturity from 11 to March, the average daily temperature of less than 20 ℃, the temperature difference is greater than 9 ℃, favorable synthesis and accumulation of sucrose 1600 tons annual rainfall of which 82.3% concentrated in 4 to 10 Month.High temperature and rainy period.The condition of water conservancy is good, the soil is mainly alluvial soil, acidic.They are very beneficial to the growth and development of the thermophilic crops.
