The latest course of apricot pruning techniques and methods

Apricot trees like light very much. no matter they use natural round head shape, natural happy shape or open hierarchical tree shape, there are not too many main branches, but the interlayer should be large, so that sunlight can enter the inner chamber, improve ventilation conditions and improve light energy efficiency. Reasonable pruning can make young trees rapidly expand their crown, increase the number of branches, bear fruit ahead of time, have high yield in the early stage, achieve high and stable yield in the full fruit period, and prolong the full fruit period.

De-adorning

De-sprouting means that after sprouting in spring, the unsuitable position and excessive number of crowded buds or twigs should be erased in time, so as to reduce nutrition consumption and make the remaining branches get sufficient nutrition and light. This method is mostly used for young trees. It is better to wipe the buds as early as possible, and the length of the shoot should not exceed 3-5 cm. At this time, the branches are not yet lignified and can be erased with their hands, and the wounds caused are easy to heal. When old trees are renewed, many useless twigs are also easy to sprout near the shears and saws, which should also be erased as soon as possible.

Pull branches

Some varieties of young trees, easy to produce some vigorous growth of erect branches, resulting in the crown is not open. For this kind of branch, a rope can pull it into a certain angle after the sap flows to sprout, so as to ease its growth, promote the growth of fruit branches and bear fruit earlier. The angle of the branch should not be too large, 45-50 degrees is appropriate, the angle is too large or flatten it, and upright branches will occur on the back, which will still grow and affect the flowering and fruiting.

For this kind of upright branches, if the branches are not cut slowly or pulled, part of the fruit branches can be formed in the front (upper) part, but after the result, the lower part is easy to be bald, reducing the fruiting part and affecting the yield and quality.

Pick the heart

To pick the heart is to pick the young part of the new shoot. For the upright branches with suitable germination position in the crown and favorable light conditions, the regenerated shoots, the elongated branches, and the upright growing mediocre branches on the back, they can all be taken out of the heart, especially when the new shoot is about 40 cm long. However, the extended branches of the main and lateral branches at all levels and the branches that replace the extended branches can not be plucked, such as increasing the angle and increasing the grade of the branches, but the number of coring should not be too much, so as not to enrich the branches.

About 10 days after the coring of the new shoot, the lower part can be branched and Lignification can be reached. However, if the heart is picked for more than 3 times, when the branches are not full, it may cause frost injury, or weaken the tree because of too many branches.

When pruning, we should pay attention to the light conditions, as long as the light is sufficient, we can produce enough nutrients to meet the needs of growth, and prevent the inner chamber from balding and the fruit part from moving out. Therefore, the tree structure should be small at the top and large at the bottom, and the distribution of branches should be sparse at the top and dense at the bottom, and big branches and twigs should be dense at the top, so that the expected effect can be achieved.
