摘要: 为了提升气象服务能力,合理掌握日光温室保温帘揭盖时间,进而提升生产水平和经济效益,利用日光温室揭开保温帘时间的数学模型,对安塞冬季日光温室保温帘揭开时间进行分析验证。根据安塞县温度和光照气候资料,计算出安塞冬季各旬平均揭帘时间,并利用数学模型和天气预报,建立了揭帘农用天气预报指数,用于指导农业生产。结果表明,数学模型适合在安塞应用,天气预报指数符合生产实际,指导意义明确,按计算所得保温帘揭开时间达到了预期效果。

Abstract: In order to enhance meteorological service capability and make a more reasonable uncover time for manufacture to control heat preservation curtain of solar greenhouse, which will further improve production level and increase economic benefits. By mathematical simulation on uncover time of heat preservation curtain, the author analyzed and verified the uncover time in winter at Ansai County. According to temperature and sunlight data of Ansai County, the auhor could calculate an average uncover time of every 10 days in winter. Meanwhile, with the support of mathematical simulation and weather forecast, the author set up the weather indexs about curtain uncover time, which would guide agricultural production. The results indicated that mathematical calculation and weather index had clear guiding effects, met production requirements, and got expected result.
