摘　　要：云南省地处低纬高原,特殊的地理条件和气候条件,为马铃薯提供了得天独厚的生长环境,四季种植,周年收获。冬作马铃薯面积和产量均接近全省马铃薯种植面积和产量的10%。该研究分析比较了不同马铃薯冬作区1981~2010年30年11~4月平均气温、降水量和相对湿度等气候要素在马铃薯生育期的时间变化规律,并较详细地评述了这些气候特征对马铃薯生长的影响。结果表明,发展冬季马铃薯在云南具有得天独厚的气候优势。Yunnan Province is located in the low latitude plateau,with special geographical and climatic conditions.It provides a unique growth environment for potato,which can be planted and harvested in four seasons.The area and yield of winter cropping potato are nearly 10% of the whole province.In this research,the time variation of meteorological indexes,such as average temperature,precipitation and relative humidity,from November to April in different winter potato cropping areas in the past 30 years(from 1981 to 2010) were compared.The advantages and disadvantages of these climatic characteristics on potato growth were reviewed in details.The results showed that Yunnan Province has climate advantages for the development of winter cropping potato.
