| 摘 要： | 为明确不同时期甜高粱茎秆含糖量的变化规律,以12个甜高粱品种为试验材料,在自然状态下进行风干贮存,采用还原糖测定法,分别对收获时、半干状态和全干状态进行茎秆糖分含量测定分析。结果表明：甜高粱茎秆中可利用的糖分随着水分的减少而减少,达到半干和全干状态时,糖分含量仅为原来的40%左右;在收获至半干状态的时间内糖分含量下降较快,而半干状态至全干状态的时间内糖分下降缓慢,3个测定时期的糖分含量差异极显著。

| Abstract: | Taking 12 sweet sorghum as experiment materials,dry and store up under natural conditions,the sugar content in stem of newly harvest,the semi-dry state and the all-dry state were measured respectively with chemical methods to identify the change of sugar content in different stage.The results showed that the amount of sugar which could be used in sweet sorghum stalks reduced with water reduction.When it came to semi-dry stage or all-dry stage,the sugar amount became merely about 40% of that in newly harvest... |
