【摘要】 对2015—2017年湖北省现代农业展示中心的中稻农情监测数据与本区域的气象资料进行时空上的相关性分析。结果表明,常年5—9月影响武汉市中稻生产的主要异常天气有营养生长期的低温、阴雨、寡照和抽穗扬花期的持续晴热高温天气,可影响中稻生长发育速度及对经济性状造成减产。结合中稻品种丰两优四号近3年的生育期和常年气象特点提出了该地区中稻生产预防、规避、减轻常年夏季高温气象灾害的建议性技术措施。更多还原

【Abstract】 The temporal and spatial correlation analysis is conducted between the monitoring data of mid-season rice farming conditions in collected at Hubei Modern Agriculture Exhibition Center in 2015—2017 and the meteorological data of Wuhan city. The results show that the major abnormal weather conditions affecting mid-season rice production from May to September in this area are low temperature, overcast and rain, insufficient sunlight in the vegetative stage and continuous high temperature and sunny days in the heading and flowering stage, leading to growth and development delay, or to a diminished production. According to the growth period of mid-season rice variety Fengliangyou No.4 in recent three years and the perennial meteorological characteristics, suggestive technical measures are proposed to prevent, avoid and alleviate the perennial drastic summer heat during mid-season rice production in Wuhan city.更多还原
