[Objective]The study aimed to analyze and predict the suitable period of laver along the coastal areas of Jiangsu Province.[Method] To enhance the ability of meteorology to service laver culture,using the modern weather forecast technology,agricultural weather prediction was developed according to the demands for meteorological conditions during laver production.[Result]From south to north,there were certain differences in the suitable periods of laver culture,breeding and harvesting,with slight variations.The forecast of the first and last days of certain water temperature could provide scientific references for the meteorological service of laver culture,and the service effect became better after it was modified with the aid of the medium-term and long-term weather prediction.[Conclusion]The research can offer theoretical bases for the culture of laver along the coastal areas of Jiangsu Province.
