宿根蔗生长后期叶面喷施KH2PO4和石灰水，能有效地提高甘蔗蔗糖分，降低蔗汁还原糖分，以KH2PO4效果较好。KH2PO4和石灰水处理使甘蔗叶片的酸性转化酶活性降低，Mg2+－ATP酶和Ca2+－ATP酶活性则明显提高。KH2PO4处理明显降低了甘蔗叶片水溶性蛋白质含量，而提高了中性转化酶活性。石灰水处理提高叶片水溶性蛋白质和类胡萝卜素含量，而使水分含量和过氧化物酶、多酚氧化酶活性降低。
Abstract：At late growth stage of ratoon crop of sugarcane, spraying KH2PO4 or limewater on the leaves increased the sucrose content in cane and decreased the reducing sugar in juice, so Improved the cane quality as compared with the control, and the KH2PO4 treatment produced a better result. Both the KH2PO4 and limewater treatments decreased the activity of acid invertase, but increased the activities of Mg2+- ATP ase and Ca2+-ATPase in leaves significantly. The KH2PO4 treatment obviously decreased the water soluble protein content, but remarkably increased the neutral invertase activity in leaves. The limewater treatment increased the contents of water soluble protein and carotenoid, but decreased the content of water, and the activities of peroxidase and polyphenol oxidase in leaves.
