摘　　要：利用朝阳市7个气象观测站2014年气象资料,分析农作物生长季的气候特征及影响。结果表明:2014年农作物生长季温度偏高,日照略少,热量条件较好;生长季降水总量偏少且时空分布极不均匀,作物苗期和成熟末期水分条件好,7—8月降水持续偏少,发生了1952年有气象记录以来最严重的"夏旱",给作物开花授粉和灌浆造成严重影响,农作物产量降低。总体来说,朝阳市2014年农业气象条件对农作物生长发育弊大于利。Using meteorological datas of 7 meteorological stations in Chaoyang City in 2014,the climate characteristics and affect crop growth season were analyzed.The results showed that the crops growing season temperature on the high side in 2014, slightly less sunshine, heat condition was good ;growing season precipitation total amount was lack spatial and temporal distribution was very uneven.Crop seedling and mature stage ,water conditionsL were good,July to August continuing low rainfall ,occurred the most serious ＇summer drought＇ since 1952 which had meteorological records. These factors have a serious impact to crop blossom pollination and grain filling.Overall ,the agricultural meteorological conditions in Chaoyang City in 2014 on the growth of crops were more harm than good.
