本文采用逐步回归法对角倍产量与它前期气象因子的关系作了主导气象因子的筛选,指出影响角倍产量的主要时期及主导气象因子是越冬若蚜速生期的极端气温;翅蚜出现期的平均气温;性蚜生育期的降雨量或湿度;干母生育期的平均气温。本文还提出,用主导气象因子建立的回归模式建行角倍产量预报和产地气候区划的可能性。
In this paper, we use the stepwise regression method to determine the dominant meteorological factors of the relationship between the relative doubling yield and its previous meteorological factors. It is pointed out that the main period and dominant meteorological factors that affect the yield multiplication are the extreme temperatures of wintering wintering. Of the average temperature; the sexual aphid during the rainfall or humidity; dry mother during the average temperature. The paper also proposes the possibility of using the regression model established by the dominant meteorological factors to predict the timescaled production and the regional climate zonation.
