基于灰色关联法的柑橘生产气象影响因素分析——以衢州地区为例

Meteorological Factors' Effects on Citrus Production Based on Grey Relational Analysis

采用灰色关联分析法,对衢州地区柑橘生长期中影响其产量的气象因素进行了研究。结果表明,柑橘在生长过程中受到平均日照、平均温度、平均降水量以及最高最低气温等因子的共同影响。在柑橘生理落果期、果实膨大期和冻害期,各气象因素影响相对较小,而在萌芽期、开花期和采摘期,各因素对柑橘产量有明显影响。其中,平均气温对柑橘产量影响最大;在萌芽期与冻害期平均降水量与柑橘产量呈负相关;平均日照对柑橘的整个生长过程及柑橘产量影响较大,并且相对稳定持续。

The use of gray correlation analysis, citrus production factor screening comparison can clearly identify the key factors influencing the citrus production. This paper is the use of gray correlation analysis, respectively Quzhou citrus bud growth, flowering,physiological fruit drop of fruit enlargement period, picking and associate degrees of frost damage analysis, and concluded that: Citrus receive the combined effect of average sunshine, temperature, maximum and minimum temperatures and average precipitation in its growth process. The largest impact on the citus production is the average temperature; various factors have an small affecting on physiological fruit drop and enlargement in citrus period. And the average precipitation and freezing of citrus production was negatively correlated. For citrus, such as different growth factors on yield different effects, and to take relevant measures based on the maximization certain citrus production.
