为了获得粮糖双丰收扩大糖料来源,在试验推广半年蔗栽培的基础上,我们从一九七七年秋季开始又引入粮糖兼用高粱进行试种和制糖试验.本县的高粱一年二熟,早季高粱的茎秆产量虽然较高,但含糖低,病虫害较多;而晚季的高粱籽粒早熟高产,千粒重大,茎秆含糖率高,当籽粒充分成熟后,高粱秆可在田内继续生长和存留1～2个月,这时已是寒冷的冬季(无霜),茎内的糖份即可明显上升.为了把高粱秆内的蔗糖煮出来,根据外地介绍的煮糖经验结合本地煮蔗糖的方法,单独用高粱秆在大锅内只能煮出糖浆和片糖,不能结晶成
In order to obtain a double crop of grain and sugar to expand the sources of sugar supply, we experimented and sorbed sugar experiments with grain-sorghum for the first time in the autumn of 1977, In the second crop, sorghum had higher stem yield in early season, but had lower sugars and more pests and diseases. In late season, sorghum grains had high yield of early maturity, high grain yield and high sugar content in stem. After the grain was fully matured, sorghum culm Can continue to grow and remain in the field 1 to 2 months, when it is already cold winter (frost-free), the sugar within the stem can be significantly increased in order to cook the sorghum stalk sucrose, according to the introduction of the field Sugar experience combined with the local method of cooking cane sugar, sorghum alone with straw in the cauldron can only boil sugar and sugar, can not crystallize into
