【摘要】 <正> 在糖高梁的综合利用上,茎秆锤度是影响产品产量与品质的重要因素之一。研究资料表明,在酒精工业生产中,茎秆锤度与酒精产量呈高度正相关。高锤度茎秆经榨制后的植株残渣,因干物质比率高,可以生产出优质饲料,从而提高糖高粱生产的经济效益。糖高梁茎秆榨制的汁液,实际上是各节段汁液的混合物,其锤度相当于各节段的平均锤度。本文的目的在于通过节段锤度的分析,研更多还原

【Abstract】 Brix degrees(BD)of different internodal segments in sweet sorghumbehaved a distribution of low-high-low with the largest BD of theinternodal segment on the upper section of the mother culm.The position ofthe low BD group in the mother culm was higher 2—3 internodes than the highBD group.The internodal segment which BD could represented the BD of themother culm was on the upper or lower see tion inthe mother culm for the highBD group,and on the middle section in the mother culm for the low BD group.The degree of varication of the internodal BD was smaller than that of thelength,diameter,fresh weight and dry weight of the internodal segment,and hadsignificantly negative correlation with the BD of the internodal segment.BDvalues of close internodal segments variated from nonsignificantly to extremelysignificantly.The BD of the mother culm extremely correlated with the dryweight,height,fresh weight and number of the internodal segment.The freshweight and dry weight expressed a higher positive effect on the BD of theinternodat segment of the mother culm.更多还原
