中文摘要:
      利用2017年3月8日到4月8日鸭梨花芽发育观测照片对照同期气象资料,分析鸭梨花芽萌发后气象要素对鸭梨花芽发育物候期的影响。结果表明:气温和地温自始至终主导鸭梨花芽发育进度,开绽、露蕾、露冠和始花关键物候期需要满足较好的天气条件和适宜积温,物候期转变时都有10℃以上的温暖天气相对应;风速、日照、降雨等气象要素对鸭梨花芽发育影响程度,在花芽萌发到开绽、开绽到始花和花期三个阶段,其影响程度、利弊各不相同。本文试图通过对鸭梨花芽发育过程各生育期气象影响因子初步分析,为探讨符合鸭梨物候发育规律的花期预报方法,提供新的研究思路。
英文摘要:
      Based on the flower-bud development pictures of Yali pear and homochromous meteorological observation data at station of Guanxian County during 8 March to 8 April in 2017, the effects of meteorological factor on the phenological periods of flower-bud development were analyzed. The results showed that the air and ground temperature dominated the development status of Yali pear’s flower-bud, the excellent weather conditions and effective accumulated temperature must be satisfied, the changes of phenological periods corresponded with warm days over 10℃. The effects of wind speed, sunlight, precipitation and other meteorological factor on Yali pear’s flower-bud development were different from the germination, beginning florescence and florescence period. This paper attempts to provide a new research idea for the prediction method of flowering period in accordance with the phenological development law of yali pear through the preliminary analysis of meteorological factors influencing the development of flower bud of yali pear in each growth stage.
