摘要: 研究洛阳邙山种植区1983—2010年 ‘迎日红’牡丹花期资料与气象资料,通过SPSS18筛选出日最高温度稳定通过0℃的积温、10 cm土层厚度处地温稳定通过4℃的平均温度和15 cm土层厚度处地温稳定通过4℃积温与牡丹盛花期有显著相关性,并利用SAS构建牡丹花期预测模型。通过对1983—2010年数据进行回代比较和2011—2012年进行试预报发现相对误差范围为-2.38%~1.51%,证明了该模型的可靠性。

Abstract: The relationship between meteorological data and flowering data of peony in Mangshan Mountain from 1983 to 2010 was investigated. The results showed that flowering data was significantly correlated with the soil temperature and accumulated temperature. Through the selected meteorological factors, a prediction model was made by using SAS system. Furthermore, the relative error between the forecasted and the factual values ranged from -2.38% to 1.51%. The model could exactly forecast the florescence, which provided a reliable reference to predicting florescence of peony.
