| 摘 要： | 利用赞皇县1971-2017年的逐日平均气温数据和2004-2017年的逐时气温数据,采用趋势分析、Morlet小波、皮尔逊系数等统计方法分析了赞皇县枣树需冷量7.2℃的界限温度变化规律,结果表明：赞皇县气温稳定升至7.2℃的初日、终日和持续日数变化不明显,初日多年平均日期是3月20日；终日多年平均日期是11月10日；持续日数多年平均日数是131天；气温稳定降至7.2℃的初日、终日和持续日数均存在一定的周期性变化规律,初日存在准12a的变化周期、终日存在准14a的变化周期、持续日数存在准12a的变化周期；气温在0-7.2℃的总需冷量多年平均小时数为1181小时；需冷量达到612℃的多年平均日期为1月19日。

Jujube in Zanhuang: Variation Analysis of Chilling Requirement and Boundary Temperature |
| |
| Abstract: | The paper aims to guide the planting of jujube trees in Zanhuang. Based on the meteorological data of the daily average temperature in Zanhuang from 1971 to 2017 and the hourly temperature data from 2004 to 2017, by using the trend analysis, Morlet wavelet, and Pearson coefficient and so on, we analyzed the variation rules of boundary temperature with chilling requirement of 7.2℃for jujube trees in Zanhuang. The results showed that: the initial day, the ending day and the duration days of the temperature rising steadily to 7.2℃ did not change significantly in Zanhuang; the average date for the initial day and the ending day was March 20, November 10, respectively; the average consecutive days was 131 days; there were some periodical changes in the initial day, the ending day and the duration days when the temperature decreased steadily to 7.2℃; and the initial day, the ending day and the duration days had a quasi-12-year, a quasi-14-year, a quasi-12-year change cycle, respectively; the average hours of chilling requirement with the temperature at 0-7.2℃ was 1181 h; the multi-year average date for the chilling requirement to 612℃ was January 19. |
