皖东农业气侯变化及其对茶树影响的研究

STUDIES ON AGROCLIMATIC CHAGES IN THE TEA GROWING REGION OF EAST ANHUI AND THEIR EFFECTS ON TEA PLANT

对近四十年气象资料进行系统的统计、分析和研究,发现皖东荼区的热量、水分和光照等农业气候条件均有明显的变化(如冬季变暖、夏季变凉、生长期延长、春茶开采期提前、降水量增多、蒸发量减少、湿度增大、光照减弱等)。农业气候的这一变化趋势对茶树生长的影响是有利的。建议充分利用农业气候的有利变化,因地制宜地发展皖东茶叶生产。

After analysing and studying meteorolgical data for the recent 40 years in the tea growing region of East Anhui, it is found that agroclimatic elements (heat, water, sun light etc.)have been changing greatly, such as warmer winters, cooler summers, longer duration of tea plant growing period, earlier beginning date of picking spring tea, more precipitation, less evaporation, higher air humidity, weaker light etc. All these are of great benefit to tea plant growth. We suggest that we take advantage of the agroclimatic changes and develop tea production according to the local conditions in East Anhui.
