中文摘要:
      基于1959—2019年气象站观测资料和2011—2020年覆盆子产量资料,分析了江西省德兴市农业气候变化及其对覆盆子产量的影响。结果表明,与覆盆子产量显著相关的气象因子分别为无霜期日数、稳定通过10 ℃初终日期间隔日数、稳定通过10 ℃积温、年极端最低气温和3月极端最低气温。5个气象因子总体呈上升趋势,但阶段性特征不同。稳定通过10 ℃积温在1980—1989年呈减少趋势,其他时段均呈增加趋势;年极端最低气温在1960—1969年和2000—2009年呈略下降趋势,其他时段呈升高趋势;1990年以前,无霜期日数、稳定通过10 ℃初终日间隔日数和3月极端最低气温总体呈下降趋势,对覆盆子生长不利,而1990年以后呈显著上升趋势,有利于覆盆子生长。
Abstract:
      Based on atmospheric sounding data observed during 1959-2019, and raspberry yield during 2011-2020, the agricultural climate change and its influence on the yield of raspberry in Dexing City of Jiangxi Province were analyzed. The results showed that, five meteorological factors exhibiting high correlations with the yield of raspberry were determined, including days of frost free periods, the duration days between beginning and ending 10 ℃, accumulated 10 ℃, annual extreme minimum temperature and extreme minimum temperature in March, and the evolution of which in the near 61 years was discussed. The results showed that the five meteorological factors presented positive trend in the near 61 years, but with obvious stage characteristics. The accumulated 10 ℃ showed a downward trend in the 1980s and an increasing trend during other periods. The annual extreme minimum temperature exhibited a small decreasing trend in 1960s and 2000s, and an increasing trend in other periods. The other 3 meteorological factors showed a downward trend before 1990, which was not good for the growth of raspberry, but after 1990, the meteorological 3 factors showed a significant upward trend, contributing to the growth of raspberry.
