摘要:

本研究基于2012—2021年在盐池县收集的黄花菜生长周期观测数据以及同一时期盐池国家基本气象站的地面气象观测资料,分析了黄花菜初花期与气象因素之间的关系。分析结果显示,黄花菜初花期与4月上旬—6月中旬的日照时长以及气温稳定超过11℃的累积温度有较强的相关性。利用这一发现,我们构建了一个预测模型,并对2022—2023年的黄花菜初花期进行了预测,预测结果与实际观测值的偏差仅为1~2 d。这表明所建立的预测模型能够准确预测黄花菜的初花期,这对于满足当地特色产业的服务需求、促进县域旅游业和经济发展具有积极意义。

Abstract:

Based on the observation data of the growth period of daylily in Yanchi County from 2012 to 2021, and the ground meteorological observation data of the national basic meteorological station in Yanchi County during the same period, the correlation between the beginning of flowering period of daylily and meteorological factors was analyzed. The results showed that there was a high correlation between the beginning of flowering of daylily and the sunshine duration from early April to mid-June and the accumulated temperature of 11℃. By using stepwise regression analysis, a multiple regression prediction model was established for the flowering period of daylily from 2012 to 2021, with a high degree of fitting. The beginning flowering time of daylily in 2022-2023 was predicted, and the actual value was different only by 1-2 days. The results show that the forecast model can accurately predict the beginning of flowering time of daylily, meets the business service requirements of characteristic industries, plays a positive role in promoting county-level tourism and local economic development.
