摘要
本文分析了溧阳地区引进种植白茶品种‘白叶1号’10年以来,前期气象条件与茶树萌动、春茶开采的关系,制定白茶萌动期和开采期预报方案,结果表明:日均温大于10℃后进入春茶生长关键阶段,本地白茶的萌动起点应在稳定通过5℃和6℃的初日之间;开采期积温预报法需要过10℃有效积温达到67℃或稳定通过6℃有效积温达到147℃,其中过10℃有效积温指标的稳定性更高;气象因子预报法选择气温和降水为主要影响因子,拟合回归方程进行预报。实际生产中综合参考各项指标,并结合白茶生长情报,可以跟踪指导茶区适时开采,对提高产量和经济效益有一定意义。
This paper analyzed the relationship between early meteorological parameters and tea sprouting or plucking date white tea cuhivar White Leaf 1 ＇ in Liyang, based on the data collected of the past decade. The results showed that critical temperature of spring tea sprouting appeared when daily temperature in the early spring was above 10℃. The first buding date started at the day after which the temperature was above 5℃. The effective accumulated temperature for reasonable plucking date was 67℃.
