Abstract: It was about 30 days for sweet cherry to bloom after heating by opening the mulching straw matress with which the blooming period lasting 10 days to 2 weeks. The physiological drop occured 17 days to 21 days after blooming , and the periods between physiological drop to fruit colouring were different during different years which lasted 29 days to 43 days. And there were little differences in the periods between fruit colouring to ripening which
were all about 10 days . Dynamic growth patterns of flushes of sweet cherries in green house were typical“double S”, and the second fast growth period was compensatory growth which was more vigorous than the first one with almost all the axillary buds germinating in longer internode . The number of new roots decreased rapidly with opening the mulching film because of leaf premature senescence , and increased with shoot compensatory growth in a slight degree.
