一、甘蔗体内的水分甘蔗是含水分量很高的作物,在组成甘蔗的化学成分中,水是主要的一个成分。据报道,甘蔗根部的水分含量为68.79%,茎部为74.95%,叶部为74.38%,种子为11.03%,可见,甘蔗根、茎、叶含水量是很高的。总之,在甘蔗鲜重中含有的元素,碳、氢、氧共占99%,在这99%中约有75%为水,其余为干物质。蔗株体内的水分有两类,即自由水和结合水。自由水是借助一定外力能自由流动的水,这种水在生物化学上可作为溶剂和能结冰的水。由于蔗株的生理过程酶促的生化反应都是 First, water cane sugar cane is a high moisture content of the crop, the chemical composition of sugar cane composition, water is a major component. It has been reported that the moisture content of sugarcane root is 68.79%, the stem is 74.95%, the leaf is 74.38% and the seed is 11.03%. It can be seen that the water content of sugarcane root, stem and leaf is very high. In summary, 99% of the elements contained in fresh weight of sugar cane, carbon, hydrogen and oxygen, about 75% of which are water and 99% of dry matter. There are two types of moisture in sugarcane plants, namely, free water and bound water. Free water is a free-flowing water that is biometrically able to act as a solvent and ice-free water. Due to the physiological processes of sugarcane enzymatic biochemical reactions are
