【摘要】：研究气象因子对芳香植物始花期的影响情况,根据始花期的早迟对指导当地农业生产具有重要意义。对2003—2014年芳香植物的始花期与平均温度、平均最高温度、平均最低温度、降水量、日照时数等气象因子的相关性进行了分析。研究结果表明:芳香植物的始花期与温度关系最密切,降水量和日照时数对始花期的影响不太大。文中还以所测数据建立了芳香植物始花期的预测模型,利用逐步回归分析结果表明:早春和冬季平均最高气温、冬末初春平均最高气温和平均最低气温及平均气温每升高1℃,广玉兰、白玉兰、二乔玉兰、含笑和香樟的始花期分别推迟1.8、5.5、1.4、2.3和2.8 d;冬季平均气温每升高1℃,阴香的始花期推迟4.5 d;开花前5周的平均最低气温每升高1℃,腊梅的始花期推迟2.2 d;晚春平均最低气温、开花前5周的平均气温和平均最高气温及平均最低气温每升高1℃,二乔玉兰、女贞、含笑始花期分别提早5.0、3.3、1.0和2.0 d。
[Abstract]:The influence of meteorological factors on the flowering of fragrant plants, according to early late flowering to guide local agricultural production has important significance. On the 2003 2014 flowering of aromatic plants and the average temperature, average maximum temperature, average minimum temperature, precipitation, sunshine time correlation between number of meteorological factors were analyzed. The results show that the aromatic plants flowering and temperature are most closely related to precipitation and sunshine time, the number of flowering effect is not too large. In addition to the measured data to establish a prediction model of aromatic plant flowering, using stepwise regression analysis results showed that the early spring and winter average maximum temperature, average in the late winter the highest temperature and the average minimum temperature and average temperature rise every 1 DEG C, Magnolia, Magnolia, two Qiao Yulan, smiling and flowering of Cinnamomum camphora delayed 1.8,5.5,1.4,2.3 and 2.8 D respectively; the average winter temperature of each A rise of 1 degrees Celsius, the burmannii delayed flowering time of 4.5 D; the average minimum temperature 5 weeks before flowering increased every 1 degrees, winter delayed flowering time of 2.2 D; the average minimum temperature in late spring, 5 weeks before the flowering of the average temperature and average maximum temperature, average minimum temperature increases every 1 DEG C, two Qiao Yulan, privet, smiling early flowering and 2 d. 5.0,3.3,1.0 respectively.
