菏泽牡丹初花期的气象条件分析

Analysis on the Influence of Meteorological Conditions on Heze Peony in the Early Florescence

本文利用曹州牡丹园历年牡丹初花期资料及菏泽气象资料全面普查可能影响牡丹初花期的气象因素,较全面分析牡丹初花期与气象条件关系。气象要素的时间尺度从旬逐步扩展到8个月。结果表明:2~3月积温和上年4~6月积温对牡丹初花期有显著相关,尤其是2~3月积温是决定牡丹初花早晚的重要因素;秋季到前冬的空气相对湿度和冬季到初春的日照时数对初花期影响也有一定影响;某气象要素特征持续1个月以上影响,才能对牡丹初花期产生明显影响;初春平均气温与牡丹初花期历史序列历史资料曲线演变趋势相似且同时发生了突变。对研究牡丹生理生化、牡丹栽培、牡丹初花期调控及牡丹初花期中长期预报有较好的参考作用。

The influence of various meteorological conditions on Heze peony in the early florescence is comprehensively studied based on detailed investigation and analysis for the historic meteorological records of Heze peony in early florescence in Heze City. The time scales of the meteorological conditions extend from ten days to eight months. The results showed that the accumulated temperature from April through June of last year and that from February through March of current year had strong effects on Heze peony in the early forescence, especially the latter; Heze peony in the early florescence was also influenced by the air relative humidity from atittm^n to early winter of previous year and from winter of previous year to the spring of current year; however, it took at least one month tbr a certain meteorological condition to exert notable influence on Heze peony; the historic variations of mean temperature of early spring and the early florescence were tbund to have a similar trend. This work was believed to be helpful tbr the study of THe physiology and biochemistry of peony, the cultivation, the regulation of early florescence, as well as the mid-term and long-term tbrecast of the early florescence of peony.
