花生荚果的大小，年份间差异较大，公斤果数变异系数达９．５７％。利用１９７９～１９９１年的徐系１号花生品种与主要气象因素进行分析。其中以７月下旬到８月下旬的日照时数与ｋｇ果数的相关系数（ｒ＝０．７３３１），达５％显著水准，直接通径系数最大（－０．７６７７），间接通径系数影响明显，与相关分析亦相吻合。表明中后期日照时数对荚果大小关系密切，影响较大。 The size of peanut pods, the year is quite different, the coefficient of variation of the number of kilograms of fruit 9.57%. The use of Xu Department No. 1 peanut varieties from 1979 to 1991 and the main meteorological factors were analyzed. Among them, the correlation coefficient (r = 0.7331) of sunshine hours and kg of fruit between late July and late August reached 5%, the direct path coefficient was the highest (-0.7677), the indirect path coefficient The effect is obvious, which is also consistent with the related analysis. Show that the sunshine hours in the late pod size is closely related to a greater impact.
