气象因子与春茶及中高档春茶产量的灰色关联分析

利用灰色关联分析法,分别以春茶产量、中高档春茶产量作为参考母序列,以春茶、中高档春茶生长期内2—3月降水量、3月空气相对湿度、4月中旬平均气温为参考子序列,对春茶和中高档春茶产量与气象因子的关联程度进行相关分析。结果表明,与春茶产量关联度最大的是3月空气相对湿度,其次是4月中旬平均气温,最小是2—3月降水量;与中高档春茶关联度最大的是2—3月降水量,然后依次是3月空气相对湿度和4月中旬平均气温。基于气象因子与春茶及中高档春茶产量的关联度,生产上应该采取措施以提高春茶和中高档春茶的产量。

Grey Connection Analysis of Spring Tea and High-middle Grade Spring Tea Yield with Meteorological Factors

Using grey connection analysis,upon the fresh spring tea leaves,yield and the high-middle grade production of fresh tea leaves as the reference for the mother sequence,upon the high-grade tea,and the growth period February to March rainfall,March air relative humidity,and middle April average temperature for reference the son of sequence,the correlation degree of spring tea and middle and high grade spring tea yield with climate factors was conducted.The results show that,the biggest correlation degree of climate factors with the fresh leaves yield is the March air relative humidity,then mid April average temperature,February-March rainfall.The biggest correlation degree of climate factors with the high-grade fresh leaves yield is February to March rainfall,then the March air relative humidity,middle April average temperature.Therefore,based on the correlation degree of spring tea and high-middle grade spring tea yield with meteorological factors,measures in the production should be taken to improve the production of tea and high grade tea production.
