影响板栗产量的气象条件分析及产量评估方法

Analysis of the Weather Conditions Affecting Chestnut Yield and the Study for the Assessment Methods of the Yield

统计近24年兴隆县板栗的产量资料与生育期的气象资料,分析了板栗产量与气温、降水、日照等气象条件的相关关系,选取与板栗产量相关好的气象要素为预报因子,用多元回归的方法建立了板栗气象产量评估方程,并进行了回代和检验。

By using the chestnut yield material and the meteorology data in the period of chestnut growth in Xinglong County for recently 24 years,the relationships between the chestnut yield and the weather conditions such as air temperature,rainfall and sunshine hours were analyzed.With the meteorological elements significantly correlated with the chestnut yield as the forecast factors,the assessment equation of the meteorology yield for chestnut was established by using the multiple regression methods,and the back substitution and testing to the equation were finished.
