Abstract：Using 8-year-old sweet cherry cultivar ‘Meizao’ and other varieties, the change of growth environment , phenophase , fruit cracking rate , physiological characteristics and fruit quality in fixed plastic rain-shelter were studied .The results showed that the temperature and humidity in rain -shelter were not significantly different from those in the open field .The light intensity in rain-shelter was lower than that in the open field , which had certain influences on the sweet cherry .Compared with control , rain-shelter cultiva-tion promoted the vegetative growth , increased the length of shoots and internode length , but decreased the di-ameter .The content of chlorophyll increased , but the ratios of carotenoid/chlorophyll and chlorophyll a/b de-creased.The mature stage of sweet cherry was delayed by 2 ~3 days.The fruit cracking rate was below 6 .2%, which was significantly lower than that of control .And the effect of preventing frost was obvious .The rain-shelter cultivation had no obvious effects on the fruit quality of sweet cherry , except that the VC content was significantly lower than that in the open field .
