Abstract: 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.
