溧阳白茶种植的气候适应性分析

Analysis on Climate Adaptability of White Tea Planting in Liyang

利用常州溧阳市多年气候资料,通过与白茶原产地的气候条件对比,分析了白茶在当地种植的适应性。结果表明,溧阳地区光温水条件符合白茶的生长要求,为白茶种植适宜区。在白茶的关键生长期春季,当地气候能满足白茶对温度变化的敏感要求并保证白化期的完成,由于气候变暖大背景,当地白茶萌动期考虑在3月下旬之前并有提早趋势;当地春季降水略欠缺,需要注意水分变化并及时人工补充喷灌。茶园的科学管理需要考虑南北山系的不同气候特点,通过合理密植创造适宜茶树生长的小气候条件,重点防范春季茶树出芽后出现的霜冻和暴雨灾害,重视肥培管理和病虫害防治,根据天气变化合理安排采摘。

With years of climate data of Liyang, Changzhou, white tea planting adaptive in the local was analyzed by contrasting to the climat- ic conditions in white tea origin. The results showed that the light, temperature and moisture conditions in Liyang areas met the growth require- ments of white tea so that Liyang was white tea planting suitable areas. In the critical growing season-spring, local climate met sensitive re- quirements of white tea to temperature changes to ensure the completion of the whitened period. Due to the background of climate warming, lo- cal white tea germination period was considered before the end of March and had early trends. Local spring precipitation slightly lacked so that there need to pay attention to moisture changes and increase artificial irrigation in time. The scientific management of tea plantations needs to consider climatic differences in north and south mountain ranges, to create micro-climatic conditions suitable for tea growing through rational close planting, to focus on prevention of frost and storm disasters when tea tree sprouted in spring, to place emphasis on fertilizer management and pest control, and to make reasonable arrangements for tea picking according to the weather changes.
