[Objective] The aim was to study growth and development law of grape under forced dormancy,and provide a reference for prolonging its picking period and enriching urban agricultural production.[Method] The rising temperature time was October 15th,30th and November 15th.[Result] The results showed that the picking period could be prolonged above 4 months by cold storage and greenhouse cultivation.Compared with the growth period under the condition of normal open field cultivation,the growth period under the condition of forced dormancy was postponed.Therefore,if ensuring to come into the market in setting time,the time to break the dormancy of grapes should be 10~15 days earlier than the time required for the open field cultivation.[Conclusion] The study provides a theoretic basis for grape cultivation under forced dormancy.
