摘要
为了进行烤烟合理布局和制订生产技术措施,利用贵州84个气象站点1961—2010年逐日温度资料,在GIS平台下推算并定点读取各乡(镇)起点温度和终止温度,确定贵州烤烟大田期的可利用日数。结果发现,贵州烤烟大田期可用日数各地差异很大,随着海拔高度的增加,烤烟大田期可利用日数不断减少。按照时限长短、分布地域、气候特点将贵州烤烟大田期可利用日数划分为4个类型区。除海拔2000 m以上地区外,其余地区大田期可利用日数均能保证烤烟的正常生长。根据各类型区的可利用日数和气候特点,提出了不同类型区的利用方式和技术要求,并对各类型区的移栽期和采收结束期提出了旬期安排建议。
Days available for tobacco-growing in fields as the basis were provided for the arrangement of its rational distribution and production technical measures.We used the daily data of 84 meteorological stations in Guizhou from 1961 to 2010 to analyze the initial temperature and final temperature for tobacco growing on the GIS platform to determine its available days in field.The results showed the days available for tobacco growing in field varied largely with locations,which reduce with the elevation.According to the length of time,geographical distribution and climatic characteristics,the days available were divided into four types of areas.Apart from the areas above the altitude of 2000 meters,available days in fields can ensure the normal growth for flue-cured tobacco.According to various areas of available days and climate characteristics,use patterns and technical requirements are presented for different types of areas,and arrangement propositions are proposed for the transplanting period and the end of harvest period for all types of areas.
