| 摘 要： | 为优化农作物品种布局和种植结构调整,促进农业持续发展,利用自动气象观测站记录齐齐哈尔市2011~2013年生长季农业气象资料,通过对比分析3a生长季的气温、地温、降雨量和风速等气象因子的变化情况,揭示齐齐哈尔市近3年农业气象条件对农业生产的影响。结果表明:齐齐哈尔市近3年生长季气温变化幅度较小,活动积温受始霜期影响较大;降雨量高于往年平均水平,各月份降雨量分布不均匀,易发生春旱、夏涝现象;生长季的强风天气出现频率高,达到40d以上,是造成春旱、农作物倒伏的主要原因。

| Abstract: | In order to optimize layout crop varieties and planting structure adjustment,and promote the sustainable development in agriculture, according to the record of agricultural meteorological data growth season for the automatic meteorological observation station in Qiqihar from 2011 to 2013, the change of air temperature, ground temperature, rainfall, wind speed and other meteorological factors of crop growth season in recent three years were analyzed, the effects of agricultural meteorological conditions on agricultural production were revealed. The results showed that temperature had small variation, the active accumulated temperature was affected by first frost period;each month the uneven distribution of rainfall was higher than average level of previous years and likely to occur the spring drought and summer flood phenomenon ; high frequency of strong winds reached more than 40 d in the crop growth season,strong wind was mainly caused by spring drought and crop lodging. |
