Abstract: To extend the supply period of fresh fruit of Chinese bayberry, 17 years old trees of‘Dongkui’are used as materials. Insect net and umbrella cloth covering the trees is used for delayed cultivation (DC), single insect net covering is used for insect-proof cultivation (IPC), and trees of open field cultivation is used as control (CK). Fruit ripening date, yield and economic efficiency under different patterns are investigated, and fruit quality is tested for two consecutive years. The results revealed that the ending date of fruit harvest of DC and IPC were delayed for 14 d and 5 d in 2016, respectively, and delayed for 16 d and 4 d in 2017, respectively, compared with that of CK. DC and IPC had better fruit quality and economic efficiency. In the year of 2017, with rainy fruit ripening period, single fruit weight, soluble solids and total sugar of DC were higher than the other two treatments. Therefore, delayed cultivation could achieve delayed maturity, improve quality and economic benefits, and the effect is more significant in rainy years.
