河南省固始县茶区茶树生长的自然地理条件研究摘要二十一世纪是注重健康和饮食的时代，作为绿色饮品的茶叶日益受到人们的 关注和青睐，而对茶树生长环境的研究也在不断深入进行中。本论文以北亚热带 的河南省固始县茶区的茶树为研究对象，采用实地考察和资料分析相结合的方 法，从气候、地形，土壤等因子入手，分析该区自然地理条件对茶树生长的作用， 以揭示影响该区茶叶产量和品质的自然因素，为本区茶叶生产服务。通过对气候条件的研究发现，本区≥10℃活动积温、平均气温和 5cm、25cm 两层土温和国内高产茶区相比偏低，导致春季茶园开园迟、轮采次数少、茶叶单 产低，却在一定程度上对提高茶叶品质有利。与国内其他茶区相比，本区年降水 量适中，各月降水量与茶树生理需求相符，空气湿度大、云雾条件优、日温较差 大、光照时间长，这些因素对茶叶品质的提高有利。茶区海拔在 419-603m 之间，相对较低，与基带的热量要求基本一致。主要茶 园在坡向和坡度上选址合理，但地表反射能力强，茶园的小气候条件差，对气温 的调节能力有限；区内土壤理化性质好，全 P 和速效 P 含量偏低，说明茶区有缺 P 的现象，应注意追施 P 肥。PH 值和国内高产茶区相比偏高，影响本区茶叶单 产的提高。微量元素含量丰富，重金属含量低，符合有机茶园土壤环境标准。总体本区茶叶单产量偏低，品质优越；春茶量大质优、夏茶产量居中，秋茶 量小苦涩味浓。关键词：茶树生长 气候地形 土壤 茶叶产量和品质 影响因素Research on physico-geographical condition of tea plants in Gushi tea region, Henan province AbstractThe 21st century is the time of health and diet, and the tea which is regard as a kind of green food has been gradually concerned by people, so the study on the growth environment of tea plant goes deeper. In this paper, based on the field work, data analysis and beginning with climate,topography，soil and so on, we took tea plant of north subtropical zone inGushi tea region, Henan province as study object and investigated how the ecological environment effected the growth of tea plant so as to further reveal the factors that effected on the yield and quality of the tea in this area and serve the tea production.By studying the climate condition, we found that the ≥10℃ activeaccumulated temperature, the mean temperature and soil temperature of 5cm and 25cm in this tea region are lower than higher-yielding regions at home, led to the delay of begin plucking of the tea garden, the reduction of times of cycle plucking and the low per unit area yield of the tea, and also led to advance the quality of tea in certain extent. The annual precipitation in this region is moderate and monthly precipitation is comfort to the physiological requirements of the tea plants. Besides, high air humidity, superior cloud and mist, excessive temperature differentials, long l
