[Method] In the research, a regression equation of celery growth and meteoro- logical factors was established, and meteorological indices of celery in growth period, meteorological disaster indices and highlights of meteorological service for farmers were analyzed in terms of meteorology based on observation of biomass, growth period, and information in national basic stations and automatic stations in regions of Hulu River. [Result] The sowing period and germination period of celery were more significantly influenced by lower temperature of spring in northern area, compared with southern area, hence, celery plants in northern area should be sown later. The suitable germination stage differed about ten days in the four regions from south to north from middle Apdl to middle May. In common climate, the regions in south of Xiao River are not suitable to grow celery under influence of higher temperature at 26 ℃. Hence, celery industry belts should be moved to the north along Hulu River. During growth period of outer leaf, however, celery were less influenced by hail. [Conclusion] The research lays foundation for meteorological service for agriculture.展开更多
