Abstract: 【Objective】Jinpingmang is a new mango variety bred jointly by Institute of Fruit Tree Research, Guangdong Academy of Agricultural Sciences and Institute of Fruit Tree Research of Chaozhou City from a single plant in a seedling population. In order to fully exploit the application and promotion potential of new varieties, the key techniques of rain shelter cultivation were studied in order to provide a theoretical basis for the rain shelter cultivation technology to be widely applied to mango production in rainy areas of southern China.【Method】Taking open field cultivation as control (CK), full rain shelter cultivation was conducted on Jinpingmang and the effects of two cultivation modes on the male and female flower rate, fruit setting rate, fruit yield and quality, fresh-keeping and storage resistance of this variety was determined and compared.【Result】Under rain shelter cultivation mode, the contents of total sugar, sucrose, soluble solids and vitamin C of the new variety Jinpingmang mango were higher than those of Zihuamang, while the contents of reducing sugar, total acid, titratable acid and crude fiber were lower than those of Zihuamang. The number of bisexual flowers, fruit quantity and fruit setting rate of Jinpingmang were significantly higher than those in open field cultivation, but under the open field cultivation conditions, they were lower than those of Zihuamang. The average yield per 667 m2 reached 608 kg in the second year after grafting, 788 kg in the third year and 1 280 kg in the fourth year. The Jinpingmang mango began to bear fruit two year after top grafting with a yield of 608 kg per 667 m2 and the yields were 788 kg and 1280 kg, respectively three and four years after top grafting. The average yield per 667 m2 increased by 348.27 kg and 72.67 kg, respectively, compared with that of open field cultivation and Zihuamang, and the income per 667 m2 increased by 5 224.05 yuan and 5 186.7 yuan, respectively, showing higher yield and economic benefits. The contents of total sugar, reducing sugar, sucrose, total acid, titratable acid, soluble solids, vitamin C and crude fibre of Jinpingmang fruit were 112 g/kg, 25.8 g/kg, 85.5 g/kg, 4.17 g/kg, 4.16 g/kg, 17.9%, 23.4 g/kg and 0.2%, respectively. Total sugar, sucrose, soluble solids and vitamin C of Jinpingmang were higher than those in openfield cultivation, while reducing sugar and total acid were lower than those in open-field. The special double-layer fruit bags with red outer and black inner had the best effect. The fresh-keeping effect was best when 40% Baikede and 50% Wanlide were mixed with 1 000 times liquid.【Conclusion】Rain-shelter cultivation technology has certain application and promotion value in mango planting in rainy areas of southern China.
