| 摘 要： | 对1961－2000年冬季气候资料统计表明，40年来浙江省柑桔主产地不同等级冻害出现的频率，从时间分布特征来看，1月最大，12月次之，2月最小；从年代分布特征来看，60年代出现频率最大，70年代次之，80年代第三，90年代最小。柑桔明显减产时，多出现冻害，而且，较强冻害出现时，可以连续两年减产，冻害是影响浙江柑桔产量的一个重要因子。提出防冻措施，对确保柑桔优势高产有重要的现实意义。

| Abstract: | On the base of the climatic data for the winter during 1961 to 2000 in the main production areas of orange in Zhejiang province the frequency of freezing injury was characterized as follow: from the monthly distribution, the freezing injury happened the most frequently in the January, next in the December, and the last in the February. From the decade distribution, it happened the most frequently in the 1960's, the second in the 1970's, the third in the 1980's, then in the 1990's. The yields reduced obviously mainly due to the freezing injury. When the heavy freezing injury occurred, the reduction of yields could last for two years. The measures against the freezing are important for improving the quality and increasing the yield in the production of orange. |
