| 摘 要： | 根据浙江省临安县和余姚市两地共20年各主要气象资料及与其相应的春茶适采期等调查资料,利用逐步回归分析程序,从45项气象因子中筛选出影响春茶适采期的主要气象因子是:3月下旬有效积温,3月份日照时数,上年10—12月的蒸发量和晴雨指数和4月上旬的有效积温、日照时数及晴雨指数,并建立了适采期预报的主体模型。同时,根据多年多点观察结果,得出茶园海拔、茶树品种、坡向等因子对适釆期预报值的修正值,利用分析过程中得到的一系列中间数据和信息。笔者还对适采期预报模型的研究方法、不同时期影响茶树生育的主要气象因子等问题进行了

| Abstract: | Twenty-year data of meteorological observation and relevant pluckingdate of spring tea from Linan and Yuyao are investigated.Based on thesedata the analysis of stepwise regression is done and the key meteorologicalfactors which affect the plucking date of spring tea is selected from 45factors.The predicting model is made out:(?)According to the observation in several districts for several years,revisionof optimum plucking date of elevation,variety,and slope direction is obtained.The problem of study method and the different key factors which affectthe growth of tea plant in different time are also discussed in this paper. |
