Planting method for mixed planting of Australian mangoes and custard apples

The invention discloses a planting method for mixed planting of Australian mangoes and custard apples. The planting method comprises the following steps of planting mango and custard apple seedlings in an interlaced manner, grafting Australian mango scions on branches of the mango seedlings, reserving main branches and auxiliary main branches according to round-head-shaped crowns, using second-layer auxiliary main branches as fruiting branches , and trimming fruiting trees four times every year; and after new buds of the custard apple seedlings germinate, reserving main branches and branches to be prepared into open-center tree shapes, and trimming fruiting trees three times every year. According to the planting method, by adjusting the custard apple production period, the Australian mangoes and the custard apples are planted in a mixed manner, the space, nutrient and water competitive relation of the two kinds of fruit trees in the annual growth period is reduced, and the utilizationefficiency of limited lan
