一、原料蔗贮存的意义1、避免霜冻危害、减少蔗糖损失义乌糖厂蔗区地处北纬29度,常年终霜期较迟(一般在3月21日),初霜期较早(一般在11月18日)。甘蔗生育期一般只有7～8个月,甘蔗蔗糖份上升期在10月下旬以后。糖厂一般在立冬过后开始收蔗榨糖。近年,蔗区面积相应得到集中和扩大,以保证糖厂有足够的原料蔗加工。众所周知,糖厂不可能在霜冻前把全部原料蔗压榨完毕,义乌糖厂过去每年约有60%的甘蔗在田间受霜冻危害,对甘蔗蔗糖份、纯度影响很大,造成了严重的经济损失。据1972、73两个榨季化验数据得出,受霜冻后的甘蔗(印度290)蔗糖份 First, the significance of raw material storage of sugarcane 1, to avoid the dangers of frost, reduce the loss of sucrose Yiwu sugarcane plant is located at latitude 29 degrees north latitude, late perennial frost late (usually in March 21), early frost earlier (usually in November 18th). Sugar cane growth period is generally only 7 to 8 months, sugar cane sugar rise in late October after. Sugar plants generally start after the winter harvest sugar cane sugar. In recent years, the sugarcane area has been accordingly concentrated and expanded to ensure that sugar cane processing plant has enough raw materials. As we all know, it is impossible for sugar mills to squeeze all the raw cane before frost. About 60% of sugar cane in the past in the past was endangered by frost in the field, causing great impact on the sugar content and purity of sugar cane and causing serious economic losses. According to 1972,73 two crop season laboratory data obtained, after the frost of sugar cane (India 290) sucrose
