[Objective] The aim was to analyze and conclude highlights of meteorolog- ical services for agriculture with the case of Celery industry belts in regions of Hulu River. [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.

Asian Agricultural Research 2013年第6期5卷 78-81页

作者： Jun SUN Cunlu SU Guangyang WE xufeng qi Ningxia Laboratory for Meteorological Disaster Prevention and Reduction Xiji Meteorological Bureau in Ningxia Agricultural Technology Promotion Center in Xiji County

By using climate data in national stations in Xiji County,Ningxia during 1981 and 2020,a regression analysis was carried out on weather data in crop growth season in three automatic weather stations in Hulu River Valley. The results showed that celery belts of Hulu River Valley was divided into two groups: early-maturing region of south Xinglong-Xiaohe where is warm and rainy,serotinous region of north Jiqiang-Xinying where is warm and cold and rainless. Four subregions: Xinlong,Xiaohe,Jiqiang,Xinying. Each sub-region was divided into five regions according to climate layer and observation in growth season: temperature accumulating planting period,low temperature seedling period,suitable temperature for external leaf growth stage,high-temperature for celery mulching-sanded plantation in different sowing periods, water and fertilizer,insect prevention,time to market sales.
