Abstract: When Yuanhong litchi was transplanted from Fuzhou to Cangnan (a southern county of Zhejiang province), changes of biological habit took place. Annual phenological phase of flower and fruit shortened for 7 days. There exist significant differences in ability to sprouting and bearing at different basal shoots in the next year. In order to obtain high and stable yield, a certain quantity of growth shoots were cultivated. The autumn basal shoots produced at the first 10 days of August gave high yield in the next year. The optimal differentiation of flower bud occurred at the end of October. The period of flower primordium formation in Cangnan was later than that in Fuzhou. Hence, it is emphasized that the early autumn shoots should be promoted and the late one controlled; the strong shoots should be cultivated and the flower production controlled; and the fruit retention and sound fruit are essential for litchi plantings in north Zhejiang.
