宣城地区水稻农用天气预报研究

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]宣城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。

Study on the Removing of Carbendazim Residue by Combination of Ca(ClO)2 and O3

Objective]The research aimed to discuss the influence of each factor in the combination of Ca(ClO)2 and O3 on removing carbendazim residue from kumquat.Method]By using Box-Behnken response surface methodology(RSM),the influences of initial concentration of carbendazim,soaking time of Ca(ClO)2 solution,soaking time of O3 water and Ca(ClO)2 concentration on the removing of carbendazim residue from kumquat were studied.Result]The effect of each factor on the removing of carbendazim residue from kumquat was ...
