摘要
本文利用1957~2018年蓟州地面常规气象观测站逐日平均气温、最低气温、最高气温、降水量,以及43个区域站从建站到2018年逐小时气温和降水等资料,应用5d滑动平均法、克里金插值法分析了蓟州区核桃树主要物候期内气象条件,结果表明:1) 蓟州区核桃树萌芽期时段内平均气温、极端最高气温、极端最低气温、平均日最高气温、平均日最低气温、降水量分别为11.1℃~13.3℃、24.1℃~29.2℃、?1.3℃~0.2℃、18.1℃~19.6℃、2.1℃~7.9℃、2.7~27.7 mm;展叶期分别为14.1℃~15.5℃、26.1℃~31.3℃、?0.3℃~6.3℃、20.7℃~22.0℃、5.0℃~10.8℃、16.3~27.0 mm;开花期分别为18.7℃~19.5℃、33.2℃~34.9℃、3.8℃~5.9℃、24.2℃~26.9℃、10.7℃~12.3℃、10.6~25.8 mm;果实生长期分别为22.5℃~25.4℃、38.8℃~40.2℃、6.4℃~8.2℃、28.1℃~31.3℃、17.2℃~20.1℃、409.5~636.4 mm。2) 萌芽期、展叶期、开花期平均日最低气温以及果实生长期平均气温、平均日最高气温均通过了0.05显著性检验,气候倾向率分别为0.3℃/10a、0.3℃/10a、0.3℃/10a、0.3℃/10a、0.2℃/10a。
This paper uses the daily average temperature, minimum temperature, maximum temperature and precipitation of the Jizhou Ground Conventional Meteorological Observatory in Tianjin from 1957 to 2018, and the data from 43 stations to the hourly temperature and precipitation in 2018, applying the 5-day moving average. The method and Kriging interpolation method analyze the meteorological conditions of the main phenological period of the walnut tree in Jizhou, Tianjin. The results show that: 1) the average temperature, extreme maximum temperature, extreme minimum temperature, average daily maximum temperature, average daily minimum temperature and the precipitation during the germination period of walnut trees in Jizhou district are respectively 11.1?C - 13.3?C, 24.1?C - 29.2?C, ?1.3?C - 0.2?C, 18.1?C - 19.6?C, 2.1?C - 7.9?C, 2.7 - 27.7 mm;those during the leaf extension period are respectively 14.1?C - 15.5?C. 26.1?C - 31.3?C, ?0.3?C - 6.3?C, 20.7?C - 22.0?C, 5.0?C - 10.8?C, 16.3 - 27.0 mm;those during the flowering period are respectively 18.7?C - 19.5?C, 33.2?C - 34.9?C, 3.8?C - 5.9?C, 24.2?C - 26.9?C, 10.7?C - 12.3?C, 10.6 - 25.8 mm;those during the fruit growth period are respectively 22.5?C - 25.4?C, 38.8?C - 40.2?C, 6.4?C - 8.2?C, 28.1?C - 31.3?C, 17.2?C - 20.1?C, 409.5 - 636.4 mm. 2) germination period, leaf spreading period, average flowering period, the daily minimum temperature and the average temperature of the fruit growing season, the average daily maximum temperature have passed the 0.05 significant test, the climate tendency rate is 0.3?C/10a, 0.3?C/10a, 0.3?C/10a, 0.3?C/10a, 0.2?C/10a, respectively.
