我场地处湘北洞庭湖区,位于北纬28.49°,东径112.54°,无霜期265天,年平均气温16.6℃,初霜期出现在11月中、下旬,终霜期3月上,中旬。11月份平均气温11.7℃、12月份平均气温5.9℃,1月份4.3℃,2月份5.2℃,极端最低气温出现过—12.8℃。冬季常有霜雪冰冻,是属高纬度中部温带蔗区。如何根据我场的气象条件和季节特点,因地制宜地推广良种,搞好早、中熟品种搭配,是提高蔗茎产量和蔗糖份,实现多产糖、产好糖的重要措施。但因我场是新植蔗区,缺乏经验,大面积种植晚熟种台糖134,品种单一,霜前不
My field is located in the area of Dongting Lake in the north of Hunan Province. It is located at 28.49 ° north latitude, 112.54 ° east longitude and 265 days frost-free season. The annual average temperature is 16.6 ℃. The first frost period occurs in mid-November and late frost season, and the last frost period is mid-March and mid-March. The average temperature in November was 11.7 ℃, the average temperature in December was 5.9 ℃, the temperature in January was 4.3 ℃, the temperature in February was 5.2 ℃ and the extreme minimum temperature was -12.8 ℃. Frost and snow often frozen in winter, is a high latitude central temperate cane area. How to promote good varieties according to local conditions according to the meteorological conditions and seasonal characteristics of my field, and do a good job of matching varieties of early matures and medium matures is an important measure to increase cane yield and sucrose content and achieve more sugar and good sugar production. However, due to my field is a new sugarcane area, lack of experience, large-scale cultivation of late-maturing species Taiwan sugar 134, a single species before the frost
