Abstract: Study on adaptability of Anji white tea introduced in Zongyang, by comparing Zongyang, Anqing’s climatic data and the soil fertility index for years with those in white tea origin Anji, we analyzed white tea cultivation adaptability in Zongyang Anqing. Results showed that Zongyang County could provide suitable light-warm, water and soil fertility for the white tea cultivation. The comparing obtained revealed that the three indexes mentioned were similar. Firstly, the spring white tea growing temperature through the beginning date of10℃ was earlier than that in Anji, but time interval between 10℃ and 15℃ was 24 d, slightly more than that in Anji, which guaranteed the white tea whitening. The ascending through 10, 15, 20℃ of Zongyang was clear, leading to early arrangements for picking. Secondly, in March, less precipitation in Zongyang, timely irrigation was required according to moisture change, in May, however, because of intensifying precipitation, much more attention should be paid to the prevention of flood disaster. The third category was soil fertility. The soil organic matter, total nitrogen, available potassium and pH except phosphorus exceeded white tea planting requirements, suggesting a reasonable spreading CaCO3, mixed fertilization, and other measures are needed to maintain fertility and humidity in Huanggongshan tea garden of Zongyang.
