First, improper thinning of branches can lead to sparse growth. Many growers remove a large number of shoots after fruiting, causing the flowering rate under the tree to exceed 40%. This leads to the regrowth of old leaves that were previously pruned, which hinders flower bud formation and results in sparse foliage. Reduced leaf density limits photosynthesis, negatively affecting the overall health and vigor of the tree.
The correct approach is to perform girdling after the spring tip growth has stopped, depending on the tree's condition. Girdling should be done for about a week to help redirect nutrients and prevent excessive flower bud formation without harming it. The number of branches to thin should be based on the tree's canopy area, with the shading coefficient maintained at around 30% after thinning. Focus on removing branches that are too long on the outer edges, thin or crowded inner branches, leggy branches with no space, competing branches, and those growing in unwanted directions.
Second, many fruit growers improperly open branch angles in spring, leading to backstrips and poor flowering. For new shoots that need better angles, they should be manipulated during semi-lignification to slow their growth. For main lateral branches with small angles, it's better to open them in autumn to avoid backstrips.
Third, some farmers twist shoots indiscriminately, increasing branch density and reducing light penetration. When there's enough space, once new shoots reach 35 cm or more, twist the tip in the semi-lignified stage (5–8 cm below the head center) to encourage flowering on the back side without blocking light. On the same main branch, twist only 3–5 tips, and keep the rest open.
Fourth, heavy pruning and short cuts often cause re-growth, leading to poor light penetration and weak flowering. Instead of heavy topping, use light pruning. Allow three to five large leaves to remain on branches that regrow after cutting, ensuring proper nutrient distribution.
Fifth, some farmers mishandle secondary shoots. Some cut them entirely, while others remove their tips or simply discard them. These practices disrupt the natural nutrient flow, reducing fruit size. The right method is to leave the fruiting shoots at the top untouched, allowing nutrients to concentrate where needed. By following these techniques, growers can ensure healthier trees, better fruit quality, and improved yield.
