Embodiment
[0027] The chemical control method that large cherry forms high-yield tree shape in advance, described method comprises the following steps:
[0028] (1) Variety selection
[0029] Select 2-year-old large cherry saplings, Huazhibao (developed by Henan Luoyang Forestry Research Institute), PBO (Tangshan Hualong Biotechnology Co., Ltd.), bud carving knife (ordinary saw blade);
[0030] (2) Specific steps
[0031] ①The big cherry adopts a slender and tall spindle shape. Due to the strong dominance at the top of the young tree, it is easy to grow excessively, and it is difficult to form a high-quality fruiting branch group; remove the top dominance at the 2-3m of the young tree and start setting the poles to cultivate the fruiting branch group;
[0032] ② 10-15 days before germination, select high-quality target buds, use a small brush to dip the small grain-sized Huazhibao and apply it evenly on the target buds, and then lightly carve 1-2cm above the target buds with a saw blade...
