The first is the time to pull the branches. The first dwarfing was in the spring and autumn. It is appropriate to pull branches with tree height 1 m, and the angle of pulling branches should be between 55-65 degrees. It should be tied to 2/3 branches with plastic tape and pulled at a certain angle with small wooden stakes on the ground. Note that the first branch pulling is the basis of forming dwarf crown, but it is not completely required, especially it is not suitable to pull down the growing point.
The second time, the branches were dwarfed, forming a happy dwarf crown tree. Dwarfing gardening technology should be put into production in the third year after planting, so the implementation of secondary dwarfing technology is particularly important, and it is best to choose two and a half years after planting, that is, May and June. At this time, pulling branches to change the growth angle of branches will significantly affect the nutritional supply of growing points, inhibit the nutritional growth of branches, promote the reproductive growth of branches, and start the differentiation of flower buds. This gardening technique is a technical measure to cultivate happy short-crowned trees, which can physiologically adjust the relationship between vegetative growth and reproductive growth and has obvious effect on promoting early flowering. The angle of pulling branches depends on the specific tree shape. Generally, the height of trees put into production in three years is controlled at about 2 meters, and the mature trees are controlled below 2.5 meters, which is convenient for manual measures such as flower thinning, fruit thinning, bagging and fruit picking.
