摘要
Abstract
Temperature increasing in dry season was faster than in rainy season, which reversed to precipitation decreasing. Tspv, had an inconspicuous increasing trend and both increased temperature and precipitation should enhance Tspv,. However, precipitation was the main climatic factor that limited crop Tspv in linxiang District. The percentage of actual rice yield to homochronous Tspv, was low, but it was increased since 2004. The results suggested that, e. G. , solving agricultural production water problems , improving utilization efficiency of water resource, adopting new high-yield varieties and improving fanning technology level were good ways for increasing the application level of crop climate potential productivity.关键词
