摘要
利用宣城3种木本植物(侧柏、刺槐和楝树)1982—2020年的物候期观测资料和同期气象资料(气温、降水和日照),通过SPSS、Excel等统计工具使用回归分析法、相关系数等统计方法进行了分析,结果表明:温度对植物始花期的影响最明显,日照和降水量次之;对侧柏始花期影响最显著的是2月,对刺槐始花期影响最显著的是4月;对楝树始花期影响最显著的是3月。
In this paper,three kinds of woody plants(platycladus orientalis,Robinia pseudoacacia and melia azedar⁃ach)in Xuancheng were studied on phenological observation data and meteorological data(temperature,precipitation and sunlight)of the same period from 1982 to 2020.Statistical tools such as SPSS and EXCEL were used for analysis with statistical methods such as regression analysis and correlation coefficient,The results showed that:the effect of temperature on the initial flowering stage was the most obvious,followed by sunshine and precipitation.The early flowering season of Platycladus orientalis had the most significant effect in February,and the early flowering season of Robinia pseudoacacia had the most significant correlation in April.The most significant correlation was in March on theearly flowering season of neem azedarach.
