以485份桃资源为材料，结合气象数据，分析2013年春季异常气候对桃开花物候期、蚜虫发生及坐果率的影响。结果表明，春季温度回升早，变化波动大且持续时间长，使得桃树花期延长，并有利于蚜虫的发生；低温对桃自然授粉坐果率有一定影响，自花授粉结实率影响稍小，桃树花量大，有花粉品种的产量基本未受影响。
以485份桃資源為材料，結閤氣象數據，分析2013年春季異常氣候對桃開花物候期、蚜蟲髮生及坐果率的影響。結果錶明，春季溫度迴升早，變化波動大且持續時間長，使得桃樹花期延長，併有利于蚜蟲的髮生；低溫對桃自然授粉坐果率有一定影響，自花授粉結實率影響稍小，桃樹花量大，有花粉品種的產量基本未受影響。

The effects of spring abnormal climate on the flowering phenological period, aphid occurrence and fruit-setting rate of 485 peach accessions in the year 2013 were studied according to meteorological data.The results showed that the earlier rising, and great and long-time fluctuation of spring temperature extended the flowering period of peach, and promoted the occurrence of a-phids.Low temperature in spring had some effects on the open-pollinated fruit-setting rate of peach, while it had slightly little effects on self-pollinated setting rate.Because peach had plenty of blossoms, the yield of peach accessions with pollens was basi-cally not affected by spring low temperature.
