Common misunderstandings and countermeasures of seedling pruning
Pruning is a key task in the maintenance of garden seedlings. Improper pruning tends to cause the seedlings to grow weak, the trees are not beautiful, and the flowers are less or the viewing effect is not good. Some common misunderstandings and countermeasures for seedling pruning are introduced below for readers' reference.
Re-tree shape is beautiful, light seedling growth pruning the seedlings, first of all to ensure that it can grow normally, and secondly, it has a more beautiful tree shape, which is conducive to viewing, which is the basic principle of seedling pruning. However, in daily work, many people put the cart before the horse, taking the United States as the first priority, and taking measures such as cutting the branches to adjust the tree shape, affecting the normal growth of seedlings. Therefore, before trimming, we must first carefully design the pruning scheme, which does not affect the normal growth of seedlings as the first priority of pruning.
Heavy branching, short cuts, lightly flowering buds In order to reduce the amount of flowering, the flowers are large and the flowering period is long. We often carry out sparse branches or short branches of flowering shrubs such as peach, eucalyptus and plum. In fact, during the pruning process, especially in the winter or early spring pruning process, under the premise of ensuring the normal growth of the seedlings and the beautiful tree shape, the stripping or short cutting of the branches can be appropriately reduced, and the excessively dense flower buds can be thinned. Buds can also effectively concentrate nutrients, so that the flower buds that remain under the flowering are large and the flowering period is long.
During the dormant period, the pruning is carried out in the light and long-term, and many people pay more attention to the dormancy of the seedlings, while neglecting the pruning in the growing period such as picking and germination. As everyone knows, the pruning of seedlings in the growing season is also very important. The pruning is reasonable, which not only makes the seedlings grow vigorously, but also forms a beautiful canopy, and can effectively reduce the workload of dormancy during the dormancy period. For example, from the middle of May to the middle of June, the topping treatment of the peach can effectively control the flower position to move up, improve the fullness of the flower bud, and the small tree topping can be formed early. In the middle and late July, the removal of dense branches can effectively improve the ventilation and light transmission conditions of the canopy, and promote the transfer of nutrition to flower bud differentiation. In addition, in the middle and late August, the topping of some flowering shrubs can also effectively control the growth of new shoots, promote the filling of branches, and improve the wintering ability of shoots.
Trimming before heavy flowering, trimming at work after light flowering, people often pay attention to the pre-flowering pruning of flowering seedlings, because pre-flowering pruning can guarantee flowering quality. Post-anthesis pruning is often overlooked, which affects the growth of such seedlings, the differentiation of flower buds, and the quality of flowering in the coming year. Post-flowering pruning is also a very important job and must be done. For example, flowering shrubs such as peach, eucalyptus, and peony should be cut off in time after flowering. If the residual flower is not cut off in time, the result will be caused, which will consume a lot of nutrients and affect flower bud differentiation, resulting in less flowers or small flowers in the coming year. . In addition, flowering shrubs such as crape myrtle, rose, etc. should be pruned in time after each flowering, which can promote new shoots and open new flowers.
Heavy short cuts, light updates for some flowering shrubs, pay attention to the short cuts of the branches when trimming, and ignore the update of the branches. For example, when pruning the sea otter, the habit of stalking the old branches of the sea otter is misunderstood, and only some branches are short-cut, while the renewal of some flowering old branches is neglected. In fact, the most luxuriant flowering of the sea otter is 3 to 5 years old, and the flowering ability of the old branches over 5 years is gradually weakened. Therefore, the flowering old branches should be updated in time to keep the whole plant in a state of blooming and blooming.
Heavy trunk culture, light main branch culture in the work, we often go to some of the street tree trunk straight, but the distribution of the main branches is not uniform, are growing on a trajectory, got a neck disease. This situation is due to the neglect of the selection of the main branch. This not only affects the opening of the canopy, but also after the strong convective weather and heavy snow, the big branches and the trunk are very prone to chapped. The correct method is to choose the main branches in the different directions when selecting the main branch. The selected branches must be evenly distributed, and the branches must be scattered up and down, so that the canopy can be opened more. The ability to wind and snow is stronger.
Heavy crown ventilation, light seedling life When pruning seedlings such as eucalyptus, plum, and paulownia, many people like to trim it into a cup shape. It is also more famous for its cup-shaped crown, which is not easy to cause pests and diseases. . As everyone knows, although the cup-shaped canopy is well ventilated, it is too much for the removal of the branches, which violates the growth habits of the seedlings and shortens the life of the seedlings. The correct method is to take a happy shape for the flowering shrubs such as eucalyptus, plum and other peaches, so that the entire canopy is oblate, which not only makes the plants ventilate and light, but also facilitates the growth of seedlings. For Fatong, if there is no wire as above and no pipe underneath, the natural round crown should be used, which not only has a large shade area, but also facilitates plant growth.
