摘　　要：对2018-2019年度湖北省油菜生长发育气象条件进行分析。结果表明,2018-2019年度湖北省油菜生育期间总的热量、雨量条件达到油菜生长需求量,光照条件稍欠不足;前期经历苗期干旱、越冬期低温雨雪寡照等农业气象灾害,立春苗情普遍较弱;花期全省平均最低气温未达到冷害标准,未出现分段结实现象,全省平均气温低于菌核病子囊盘萌发适温,未出现连阴雨天气,菌核病发生较常年明显偏轻;角果期晴雨相间,未出现大面积倒伏。与2017-2018年度相比,冬前播种出苗期气象条件两年度相当,越冬期气象条件各有利弊,春季蕾薹-角果成熟期气象条件好于2017-2018年度。The meteorological conditions of rapeseed growth and development in Hubei province from 2018 to 2019 were analyzed.The results showed that during the growth and development of rapeseed of 2018—2019 in Hubei province,the total heat quantity and rainfall in the main rapeseed-producing areas could meet its growing demand.However,there was a light deficiency.The seedling growth statues was weak because it went through agrometeorologica disasters like drought in the seedling stage,low air temperature and deficient light with rain and snow during the overwintering period.During the flowering stage the average lowest air temperature of the whole province was higher than the temperature criterion of chilling damage.There was no segmental fruiting phenomenon.The average air temperature of the whole province was lower than the suitable temperature for apothecia germination of Sclerotinia sclerotiorum.Moreover,there was no continuous rain and a mild occurrence of Sclerotinia sclerotiorum.During the pod-filling stage sunny day and rainy day alternated without a large scale of lodging.Compared with 2017—2018,there was similar meteorological conditions in the seedling stage.But the meteorological conditions showed different advantages or disadvantages during the overwintering period.There was better meteorological conditions this year than 2017—2018 from budding stage to pod-maturing stage in spring.
