Abstract: The aim of the study is to clarify the change characteristics of sugar-cane and its yield and sugar content loss after different types of freezing injury,so as to improve the grade indexes of sugar-cane chilly injury or freezing injury. The author investigated the sugar-cane field disasters in the winter from 2007/2008 to 2010/2011 and analyzed injury effect on the main sugar-cane varieties in different climate zones in Guangxi Province and the relationship between sugar-cane yield, sugar content loss and meteorological data in typical cold disaster years. The grade indexes of sugar- cane chilly injury or freezing injury and its loss were established or improved, and its apparent affected symptoms were formulated. The results had positive significance on the dynamic monitoring of sugar- cane chilly and frozen injury, early warning and loss evaluation, as well as the sugar-cane disasters investigation and prevention measures.
