  • 摘要:采用江西省宜黄县烟叶种植的数据,使用模糊隶属度函数构建风险评估模型,针对苗床期中播种前、播种期、苗期等环节的气象灾害风险进行评估。研究结果表明:播种前,根据未来10 d的天气预报计算平均气温,并计算平均气温低于10 ℃的天数,来决定提前播种的天数,从而保证烟叶的播种顺利;播种期,测量大棚内温度,根据烟叶适宜的不同温度区间,采取不同的增温、保温或者降温措施,从而保证烟苗发芽的措施;苗期,监测棚内外温差,采取不同的增温、保温或者降温措施,从而促进烟苗的正常生长。

  • Abstract:Based on the data of tobacco planting in Yihuang County of Jiangxi province,a fuzzy membership function was used to construct a risk assessment model to evaluate meteorological hazards in seedbed stage.Results showed that:before sowing,determining sowing date by calculating average temperature of next ten days according weather forecast in order to ensure smooth sowing of tobacco;sowing time,via measuring temperature of greenhouse and temperature range which was suitable for tobacco,adopting measures of temperature increase,heat preservation or cooling in order to ensure sprouting of tobacco seedlings;during seedling stage,measures of temperature increase,heat preservation or cooling was adopted to promote normal growth of tobacco seedlings by monitoring temperature difference inside and outside greenhouse.
