摘要

[Objective]The research aimed to study the best serve way of agricultural rice weather forecast product for production of rice in Xuancheng area. [ Method] Based on (he enhancement comprehension of importance on agricultural weather forecast, the contents of agricultural rice weather forecast product and needs of real production of rice in Xuancheng area were analyzed combined with meteorological conditions and actual work experience for rice production services. [Result] The results showed that the content of agricultural weather forecast of rice in Xuancheng area should mainly contain agricultural activities, agricultural meteorological disaster. Agricultural activities weather forecasts con-tain forecasts of rice suitable sowing time,suitable transplanting stage,field ferterlizing time,control of diseases and pests,field drying and tiller control time, irrigation and drainage,harvest and sun-cure lime. Agricultural meteorological disaster devices contain forecasts of chilling injury, high temperature damage, flood producing torrential rain,strong winds and relative coumermeasures,snow disasters. [Conclusion]The agricultural weather forecast and its servies can be done well on the premise of understanding of location agricultural activities and planting distribution , the familiarity of growth dynamics, weather index and practical agronomic technique .%[目的]为使宣城地区水稻农用天气预报更好地为水稻生产服务.[方法]在加强农用天气预报重要性认识的基础上,结合宣城地区水稻生产过程遇到的天气条件和实际工作的开展,分析宣城地区水稻农用天气预报的内容及实际水稻生产的气象预报需求.[结果]宣域地区农事活动的预报项目有水稻适播期预报、水稻移栽期预报、农田施肥期预报、病虫害防治预报、晒田控蘖期预报、灌溉排水预报、收获晾晒期预报等.农业气象灾害服务产品包括低温冷害预报、高温热害预报、暴雨洪涝预报、大风预报和灾后措施、雪灾预报等.这些预报产品在实际水稻生产中起到了重要的指导作用.[结论]充分了解服务范围内水稻种植布局、种植制度和农事活动是编制、开展好水稻农用天气预报服务的前提.熟悉水稻的生长动态、相应的气象指标和可行农技措施是开展好农用天气预报服务的基础.农业情报共享是做好水稻农用天气预报服务的支撑.
