摘要
根据草莓大棚栽培生长、产量和同期青浦区气象资料,应用数理统计中的相关分析方法分析了大棚草莓生长、产量与气象条件关系。结果表明:草莓大棚内10 cm高日平均温度、日最高温度、日最低温度,在晴天天气下比青浦区气象站分别高4.9℃、14.3℃和2.3℃,在多云天气下分别高5.2℃、15.1℃和1.7℃,在阴雨天气下分别高3.0℃、7.5℃和1.9℃;大棚草莓的农业气象灾害在繁苗期和移栽生长期是高温、暴雨和热阵雨,在开花收获期是连阴雨、暖湿天气、低温冻害、高温、大风和暴雪积雪;在此基础上建立了草莓农业气象灾害预警指标,为青浦地区草莓气象业务服务提供技术支撑。
According to the strawberry growth and yield data in vinyl-house culture and the meteorological observation data of the corresponding period,the relationship between the strawberry growth and yield and the meteorological conditions were analyzed by mathematical statistical method.The results showed that compared with the Qingpu Weather Station-observed values,the daily average temperature,maximum temperature and minimum temperature at 10-cm height inside vinyle houses were respectively 4.9 ℃,14.3 ℃ and 2.3 ℃ higher in sunny days,respectively 5.2 ℃,15.1 ℃.and 1.7 ℃ higher in cloudy days,and respectively 3.0 ℃,7.5 ℃and 1.9 ℃ higher in rainy days;The agrometeorological disasters of strawberry vinyl-house culture were high temperature,rainstorm and hot shower at seedling stage and transplanting and growing stages,and rain for several days,warm and wet days,cold injury,high temperature,gale,heavy snow and accumulated snow at flowering and harvesting stages.According to the above results the agrometeorological disaster early warning indicators of strawberry were established so as to provide technical support for the agrometeorological service to strawberry production in Qingpu area.
