Ningbo Viticulture New Technology And Promotion Strategy

Grape is one of the most important fruit in Ningbo, and plays a major role in rural economics development. This thesis analyzed the factors that affect Ningbo grape industry development, summarized the status of facility cultivation for grape. In order to improve the current planting system of grape, it is great important to introduce new technology and method for the growth of fruit trees, perform the research on new pattern green-house structure, grape bagging and root restriction cultivation.The modified grape green-house system consists of concrete, steel tubes and steel strings, which meet the environmental conditions in Ningbo. The main materials for the green house are concrete pole, steel tube and strand. One row per shed, width of individual shed and distance between concrete poles are fixed. The concrete pole is fixed vertically and horizontally by strand, the top of which are covered with steel tube and green-house roof. Steel tubes between individual sheds are connected by steel strings and strands. This modified type of green-house might be widely applied since it is characterized by simple structure, wide application, easy operation, wind resistance, better light transmission.Grape fruit bagging greatly decreased the incidence of a disease of grape, and improved the outlook quality. Soluble solids concentration increased and the grape berry showed good color when bags are removed 10 days prior to harvest. There was no significant difference among different types of bags except white bags, which had best fruit qualities.Results of 'Meirenzhi' grape in root resistance showed that growth of root and above surface in different cubage differs greatly. As the cubage of the box reduced, the weight of fresh and dry root, the number of roots reduced and the growth of the part above ground is restricted apparently, with main phenomenon that the diameter becomes thinner, growth becomes slower, branches turns out to be fewer and shorter in length, the weight of the root cap reduces but the total length of roots and branches increases.It was showed that root resistance controlled the growth tendency, restrained the length of the new shoot tips, shorten the length between burls, and increased incidence of bourgeoning of buds of branch tip and the possibility of developing into branches in next spring.In addition, the present results also showed that root restriction contributed to the size and quality of fruit. The effect of the root restriction with box mainly appeared in the second growth period, while the effect of root restriction with bag was seen throughout the whole growth. Root restriction significantly increased weight of fresh fruit, soluble solids concentrations, and promoted accumulation of dry matter and forming of fruit flavor.The strategy in the expanding and development of technology for grape planting in China was also discussed.
