对不同品种、不同时期甜高粱茎秆汁液锤度变化规律研究的结果表明:主茎秆各节段锤度最高部位基本上出现在4～6节,并可用各节段锤度的平均值代表该植株汁液锤度。实际测定汁液中的总糖含量高于用WYT—I型糖量折光仪测得的锤度,说明总糖中除蔗糖、葡萄糖、果糖3种可发酵糖外,还存在其它糖类,并说明了汁液锤度与总糖含量之间存在着极显著直线相关性,在测定锤度后,用回归方程式可求得总糖的含量,为更好地利用甜高粱茎杆汁液中的总糖提供了理论依据。
The results showed that the highest part of the billet in each section of main stem appeared in 4-6 sections, and the average of the brix of each section could be used to represent The plant juice brix. The actual measured content of total sugar in the juice is higher than that measured by the WYT-I type of sugar refractometer, indicating that there are other sugars in the total sugar except 3 kinds of fermentable sugars, such as sucrose, glucose and fructose, There was a significant linear correlation between juice brix and total sugar content. After the brix was measured, the content of total sugar was determined by the regression equation. In order to make better use of the total sugar in the sweet sorghum stalk juice The theoretical basis.
