信阳大棚草莓农业气象灾害预警指标研究及应用

摘要：［目的］研究信阳大棚草莓生长期间主要气象灾害指标和应用。［方法］利用信阳市气象局观测站气象资料和信阳市农业技术推广服务中心提供的大棚草莓生长、产量、主要资料，对信阳市农科院草莓种植园内气象要素光、温、水与棚内草莓产量关系，采用相关分析法进行分析；棚内温度与气温关系模型，采用多元线性回归法。［结果］在建立棚内温度与外界气象站气温关系模型的基础上，进一步研究了大棚草莓生长、产量与气象因子的关系和农业气象灾害的影响，确立了大棚草莓生长期间气象灾害预警指标及防御对策。［结论］在品种和生产技术相同的条件下，草莓单产的高低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，为信阳草莓生产期间开展气象专题服务提供技术支撑。同时根据建立的指标，通过农业智慧气象小气候仪进行超极限温度报警和干旱肥水一体化自动灌溉装置，为大棚草莓生产管理提供方便。

Research and Application of Strawberry Agro-meteorological Disaster Warning Index in Xinyang GreenhouseLU Shu-xian et al (Meteorological Bureau of Pingqiao District, Xinyang City, Xinyang, Henan, 464000)

Abstract: Objective] To study the main meteorological disaster indicators and application during the growth period of strawberry in Xinyang greenhouse. Method] Using the meteorological data from the observation station of Xinyang Meteorological Bureau and the greenhouse strawberry growth, yield, and main data provided by Xinyang Agricultural Technology Extension Service Center, the meteorological elements in the strawberry plantation of Xinyang Academy of Agricultural Sciences, light, temperature, water and shed The relationship between strawberry production in the house is analyzed by correlation analysis method; the relationship model between temperature and air temperature in the shed uses multiple linear regression method. Result] Based on the establishment of the relationship model between the temperature in the greenhouse and the temperature of the external weather station, the relationship between the growth, yield and meteorological factors of the strawberry in the greenhouse and the influence of agrometeorological disasters were further studied, and the meteorological disaster warning indicators and indicators during the growth period of the strawberry in the greenhouse were established. Defense countermeasures. Conclusion] Under the same conditions of variety and production technology, the per unit yield of strawberry is affected by both the meteorological conditions in the shed and the meteorological disasters outside the shed. Summarize the agro-meteorological disasters and early warning indicators during the strawberry growth period, and provide technical support for the development of meteorological special services during the strawberry production period in Xinyang. At the same time, according to the established indicators, the ultra-limit temperature alarm and the integrated automatic irrigation device of drought, fertilizer and water are carried out through the agricultural intelligent meteorological microclimate, which provides convenience for the management of strawberry production in the greenhouse.
