Embodiment 1
[0030] The experimental garden is located in Yinjiazhuang Village, Xiazhang Town, Daiyue District, Tai'an City, Shandong Province. The sweet cherry varieties are "Brooks", "Meizao" and "Sumit", and the rootstock is Gisela No. 6. The 3-year-old seedlings with branches were planted in 2015, with a row spacing of 1 meter x 3 meters and an area of 2 mu.
[0031] Erection of support: The support is composed of 4 steel wires with fixed heights of 1.5 meters, 2.2 meters, 3 meters and 3.5 meters respectively, and the central stem is bound to the steel wires; the distance between plants and rows is 0.8-1.0m×2-3 m, 667m 2 Plant 220-420 plants, and the specific planting density should be appropriately adjusted according to the growth potential of the variety and rootstock combination, soil fertility conditions and planting mechanization degree; Upright and strong, the trunk height is about 50-60cm, and 30-50 fruiting branch groups grow evenly on it, with a length of 5-50cm; the first...
Embodiment 2
[0048] The experimental garden is located in Yinjiazhuang Village, Xiazhang Town, Daiyue District, Tai'an City, Shandong Province. The sweet cherry varieties are "Hongmi", "Brookes", "Sumit" and "Meizao", and the rootstock is Gisela 6. The 2-year-old seedlings were planted in the spring of 2017, with a row spacing of 0.7 m x 2 m and an area of 2 mu.
[0049] When planting, the tree is bound to the steel wire of the support, and the stem is not fixed. From a height of 50cm above the ground, every 10-15cm, select high-quality buds in different directions, and engrave the buds at 0.5cm above the buds to promote directional branching. Make the small fruiting branches distributed in a spiral shape ( Figure 7 ). Maintain the advantage of the central trunk extending the shoot, cultivate the branches that germinate on the main trunk as the fruiting branch group, and pick the new shoots continuously; in winter, the branches that germinate on the central trunk are cut short, and th...
