摘要
为明确黔西南州烤烟种植气候特点,本研究选用烤烟大田期不同月份的气温、降水量、日照时数,采用比较研究、相似性分析和聚类分析方法,研究了黔西南州与国内外主要烟区烤烟大田期气候的差异和相似性。结果表明:黔西南州烤烟大田期的日平均温度在20℃以上,降水量在900 mm以上,日照时数在700 h以上,具有日均温中等,降水量较多,光照和煦的特点,具备了优质烟叶种植基本条件和优势。黔西南州烟区烤烟大田期气候与国内的遵义、玉溪和龙岩中度相似,与国内的郴州和国外的巴西、津巴布韦相似度较低。贞丰县与其他5个县(市)烤烟大田期气候差异较大。采用烤烟大田期的月均气象因子更能明晰烟区气候特征。
To clarify the climate characteristics of tobacco planting in Qianxinan of Guizhou,the temperature,precipitation and sunshine duration of tobacco field period in different months were selected,and then comparative study,similarity analysis and cluster analysis were used to study the difference and similarity of climate in tobacco field period between the region with major domestic and overseas tobacco-growing areas.The results show that:the average daily temperature in Qianxinan of Guizhou during tobacco field period is above 20℃,the precipitation is above 900 mm,and the sunshine hours are over 700 hours.It has the characteristics of moderate daily average temperature,more precipitation,sunshine and warmth,and has the basic conditions and advantages of high quality tobacco planting.The climate of tobacco field period in the region is moderately similar to Zunyi,Yuxi and Longyan in China,but less similar to Chenzhou in China and tobacco planting areas in Brazil and Zimbabwe.The climate of tobacco field period in Zhenfeng County is quite different from that in other five counties(cities)of the prefecture.Thus,the monthly average meteorological factors in the tobacco field period can better clarify the climate characteristics of the tobacco area.
