摘要
在连续11年对516株固定样株测产的基础上,运用灰色关联分析方法,对17个气象因子进行分析。结果表明,上年11月日照量、上年7-8月蒸发量、1月平均温度和年日照量等因子对油茶产量影响最大。
On the basis of yield investigation in 516 oiltea plants for as long as 11 years, 17 meteorological elements were analysed using grey correlation analysis. The results show that the hours of sunshine in November of the previous year, the state of evaporation in July and August of the previous year, the mean temperature in January as well as the annual hours of sunshine exerted the greatest influence on the yield of oiltea plant ations.
