摘要
Abstract
The average annual temperature data in Recent 30 a ≥10 ℃ accumulated temperature by selected 50 meteorological stations of Liaoning province in 1980 ~2015.the changing seasons and periodic variation tendency and its effect on agricultural production.The results show:the Liaoning ≥10 ℃ accumulated tem-perature increased in 1980 ~2015,the increase for several days,in advance of the initial date,the date of termination of the extension,combined with the introduction of different regions and cropping peanut varieties meteorological factor analysis,the presence of multiple cropping area of cultivation boundaries northward ex-pansion trend by ≥10 ℃ accumulated temperature as the main division basis,combined with meteorological data in different regions,the regional division of Liaoning Province potato cropping distribution to take advan-tage of light and heat resources,increasing multiple cropping index,improve land utilization.关键词
