【摘要】 通过对信阳7县2区茶叶生产状况的调查,利用9个气象台站1971~2000年气候整编资料及局地农业小气候观测资料,在对信阳绿茶产区自然地理和生态环境进行考察的基础上,按照茶树栽培环境和茶园地理特征将其细分为淮南丘陵茶区、豫南山地茶区两种类型,并对茶区光、热、水等农业气候资源进行了分析评价。结果表明信阳茶区茶树生长季节的热量条件适宜,降水量适中且分布均匀,年平均相对湿度为75%,日光散射辐射的比例高,云雾天数最长可达160 d,光、热、水气象要素同期协调递增,其优越的自然生态环境和独特的过渡气候条件,是造就“信阳毛尖”名品绿茶质量的真正原因。并提出了“信阳毛尖”走可持续发展道路的策略。更多还原

【Abstract】 According to the meteorological data from 1971 to 2000 and the local agricultural microclimatic observation data in 9 meteorological observatories in Xinyang,the green tea production area was divided into South of Huai-River hilly plantations and Yu’nan mountainous plantations based on the cultivation environment and geographical characteristics.The agricultural climate resources such as light,heat and water were analyzed and evaluated.The results showed that the heat condition was favorable,precipitation was moderate and evenly distributed,the mean annual relative humidity was 75%,proportion of scattering daylight was high,the number of cloudy and misty days in a year could get to 160 d,and light,heat and water increased by degrees in line during the corresponding period.All these favorable conditions add to the good quality of the famous brand "Xinyang maojian".The strategies for "Xinyang maojian" to sustainably develop were put forward.更多还原
