【Abstract】 In this paper was studied relationships between yield fluctuations of groundnut and meteorological conditions.The conclusions ware as follows:A.To analyse the yield alignment of groundnut crop in a certain province,city autonomous region and the whole nation.It was found that there was not only an ascendant trend in varying degree,but also the fluctuation year by year.B.The change of yield negative fluctuation by time was estimated and the years with significant yield negative fluctuation were pointed.The fluctuations of precipitation,temperaturs and the meteorological calamities by it’s influence were the weather and climatic causes of yield fluctuation.C.Because of the climatic possibility took place significant change,it is very important to raaserch on the relationships between the groundnut yield fluctuation and meteorological conditions and to inquire into certain measures.更多还原
