信阳市大棚草莓农业气象灾害预警指标及防御措施研究

Research of Strawberry Agro-meteorological Disaster Warning Index in Xinyang Greenhouse and Its Defensive Measures

为了研究信阳大棚草莓生长期间主要农业气象灾害指标及防御措施,利用信阳市气象局观测站气象资料和信阳市大棚草莓生长、产量主要资料进行分析研究。结果表明,草莓苗期的主要农业气象灾害为阶段性干旱和高温,草莓苗定植后至盖棚膜前的主要农业气象灾害为高温干旱、热阵雨和暴雨,草莓棚覆盖薄膜后的主要农业气象灾害为低温冻害。通过分析,确立了大棚草莓生长期间农业气象灾害预警指标及防御对策。在品种和生产技术相同的条件下,草莓单产受棚内气象条件和棚外气象灾害的共同影响,总结出草莓生长期间的农业气象灾害及预警指标,可为信阳草莓生产期间开展气象专题服务提供技术支撑。

In order to study the main agro-meteorological disaster index and defensive measures during the growth period of strawberry in Xinyang greenhouse,the meteorological data from the observation station of Xinyang Meteorological Bureau and the main data of growth and yield of Xinyang greenhouse strawberry were analyzed and studied.The results showed that the main agro-meteorological disasters in the strawberry seedling are periodic drought and high temperature,the main agro-meteorological disasters from the planting of strawberry seedlings to covering film of greenhouse are high temperature and drought,hot shower and rainstorm,the main agro-meteorological disasters after covering film of strawberry greenhouse is low temperature and freezing injury.Through analysis,this paper established agro-meteorological disaster warning index and defensive measures during the growth period of strawberry in greenhouse.Under the conditions of the same varieties and production technology,the yield of strawberry was affected by both the meteorological conditions inside the shed and the meteorological disasters outside the shed.Summarizing the main agro-meteorological disaster index and defensive measures during the growth period of strawberry in Xinyang greenhouse could provide technical support for the development of meteorological services during the production period of strawberry in Xinyang.
