September is a good time for apricot tree autumn shears. Pruning apricot trees in autumn not only saves tree nutrients, opens up light, eases tree growth, promotes flower bud formation, but also reduces the workload of winter pruning. In order to allow the majority of growers to better pruning, on August 26, the reporter interviewed Liu Zhenzhong, an associate researcher at the College of Horticulture, Northwest A&F University.
Opening angle Liu Zhenzhong told the reporter that the opening of the branches can promote the branches of the lower branches to form flowers, prevent the result parts from moving outward, and the phenomenon that the flowers are "high".
The thinning branches of the branches are mainly used to remove too many branches in the upper part of the tree, so that the inner scorpion sees light, so that the flower buds are formed, and more nutrients are preserved for the wintering of the tree. Moreover, at this time, the pruning branches should be cut off from the bottom. If a short pile is left, a large number of branches will be sprouted, which will cause nutrient loss and unfavorable flower bud formation.
Liu Zhenzhong said that the excessive height of the tree will increase the demand for nutrients, which will inevitably increase the cost of planting. Therefore, in view of the fact that the existing tree is generally high, it is necessary to do a good job of controlling the height and control the height of the tree at 1.5 to 2 meters. He suggested that it is best to carry out the growth of the new shoots of the fruit trees after the growth of the new shoots. The wounds after the fall are first smeared with bactericide and then wrapped with plastic cloth to prevent the wound from flowing.
