| 摘 要： | 通过评价1958-2008年库尔勒香梨越冬期间及早春低温资料,分析了历年冻害发生情况及冻害成因.结果表明:1958-2008年,气温异常偏低年份有9年,香梨发生了6次严重冻害,其中5次严重冻害发生在越冬期间,早春冻害1次(2005),剩余3年气温在临界线附近,没有造成严重冻害;1958-1986年极端最低气温变化趋势基本正常,之后有升高趋势;2007-2008年冬季气温异常偏低,导致了大面积冻害;香梨冻害发生临界温度大致为-20 ℃;香梨冻害与极端低温、低温持续日数、降温幅度、降雪厚度及持续时间、立地条件及管理水平等因素有关. |

| Abstract: | The occurrence of freezing injury and its cause of Korla Fragrant Pear over years in Korla area of Xinjiang was investigated by the data observed in 1958-2008.The results showed that there were 9 anomaly cold years in 51 years,severe freezing injury occurred during 6 years in which 5 years were in over-wintering period,1 year was in early spring period(2005),and in the remaining 3 years air temperature were a bit lower than critical temperature,hence,there was no severe freezing injury occurred.The variatio... |
