| Abstract: | Based on the conventional meteorological data of temperature,accumulated temperature,precipitation,sunshine,frozen soil and frost-free period from five stations(including Liaozhong,Kaiyuan,Dawa,Donggang and Zhuanghe) in Liaoning Province from April to September during 1960-2009,the climatic changes in growing season in rice producing area of Liaoning Province were analyzed.The results showed that average temperature,frost-free days and accumulated temperature increased in growing season in rice producing area over the past 50 years,while average maximum depth of frozen soil,precipitation and sunshine duration went down with fluctuation. |
