义乌县蔗区冬季平均气温低,常年最低温度零下6～7℃,有的年份零下8～9℃,无霜期短,甘蔗生长期一般在210～240天。“立冬”边如遇寒潮袭击即有初霜出现, “小雪”边有重霜, “大雪”边后有严重冰冻,这是我县气候发生的规律。俗语“有糖无糖‘立冬’榨糖”是有一定根据的。过去,我厂就是根据气候条件的特点,每年榨季只好在“立冬”前后开榨,12月中旬结束,榨期仅40天左右,才能避免甘蔗受冻害。几年来,在厂党委领导下,我们在生产实践中,不断掌握唯物辩证法,逐步摸索和掌握原料蔗的贮藏技术,积累了一些经验,延长了 The average temperature in winter in Yiwu sugarcane area is low, with the annual minimum temperature of minus 6 ~ 7 ℃, some of the years of minus 8 ~ 9 ℃, frost-free period is short, sugar cane growth period is generally 210 ~ 240 days. “Li Dong ” side in case of cold wave attack that there is the first frost appears, “snow ” side heavy frost, “heavy snow ” side of the serious freezing, this is my county climate occurs.
