摘要: 为明晰甘蔗遭受不同寒冻害类型影响的症状变化及其产量、糖分含量损失情况,进而完善甘蔗寒冻害等级指标体系。综合2007/2008—2010/2011年冬季广西南、中、北甘蔗主产区不同甘蔗品种遭受寒冻害影响调查分析与典型寒冻害年份甘蔗产量、蔗糖分含量损失与气象资料相关关系分析。建立和完善甘蔗辐射型、平流型寒冻害等级指标及甘蔗产量、蔗糖分含量寒冻害损失指标,规范甘蔗不同寒冻害类型等级下受害表观症状。研究结果对开展甘蔗寒冻害动态监测预警与灾损量化评估及灾情调查、灾害防御等有积极意义。

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.
