摘要
利用2017年鸭梨花芽发育影像照片、精准判定鸭梨花芽发育物候期,以物候期为依据对照分析鸭梨花芽自萌发到开花发育过程与气象影响因子的关系。研究表明:气温自始至终主导鸭梨花芽发育进度,前期以气温变化影响最大,花芽开绽后日照、风、降水等要素影响增大,不同发育阶段影响程度各不相同,后期物候期转变节点温度有明显特征。气象资料统计与鸭梨花芽发育物候期一一对应,严谨、精确、可靠;以积温历年平均值为预报指标制作花期预报,得到精准预报结果。该研究方法符合鸭梨花芽发育规律,为植物花期预报研究提供了新思路。
The phenology of Chinese pear germinate was accurately determined by the image of Chinese pear germinate in 2017, the relationship between development process of Chinese pear from germination to flowering and meteorological influencing factors was analyzed based on phenology period. The results showed that the temperature was the main factor in the development of pear germination, and the temperature was the most important factor in the early stage. The influences of sunshine, wind, precipitation and other factors increased after flower germination opening, which resulted in different effects on different development stages of Chinese pear. The temperature of the transition node in the late phenology period had obvious characteristics. The temperature and weather near the flowering period are the determinants of the opening of pear flowers. Flowering period forecast was made with the annual mean of accumulated temperature, obtaining accurate forecast results. The method accorded with the law of flower germination development and provided a new idea for plant flowering forecasting.
