SHANGHAI VEGETABLE SUPPLY AND LOCAL PRODUCTION
The vegetable production industry has developed greatly in the last 40 years in Shanghai which includes greenhouse crop production. Prior to 1964, vegetables were grown in the open field, but since that time, vegetables have been produced under small plastic tunnel, large plastic tunnels and then expanded to multi-span glasshouse culture. Dutch-style heated glass greenhouse designs have been successfully used in vegetable culture in Shanghai, providing yield of tomato and cucumber that are up to four to six times greater than the tunnel culture. In the 1990s, vegetables grown out of Shanghai began to enter the city, and gradually held most of the local market, which brought about great impact on Shanghai vegetable production. Under the condition that local vegetable production is gradually losing local market share by the impact of huge supply all over the nation, Shanghais vegetable industry is facing the challenge to improve its competitive ability by targeting the segment market and developing products characterized by freshness and quality. Shanghai has to adjust crop proportion, promote protected cultivation, expand resource saving and environment friendly cultivation area, and enhance the cooperation with national vegetable production base. Besides, agriculture parks also have great development potential. At the same time, for sustainable development of vegetable industry, local government should give more support in scientific research and breeding competitive vegetable enterprise.
