What are the precautions for pruning a kiwifruit tree?
When planting a kiwifruit tree, you must do a good job of pruning, and when pruning kiwifruit you should pay attention to adjusting the pruning method according to the tree vigor and tree age, so as to prevent over-pruning. When the pruning work is done well, it can improve the ventilation and air permeability of the fruit tree, enhance its photosynthetic capacity, and increase yield and quality. However, there are many points we need to pay attention to when pruning. Below, the editor brings you the precautions for kiwifruit pruning. Let's take a look!
1. Prune according to the tree
When pruning, we should pay attention to observing all aspects of the kiwifruit tree, such as its variety and growth years, because due to these different factors, the method and intensity of pruning will change to a certain extent. Many fruit growers do not take these factors into consideration when pruning and prune blindly. And using the same pruning method alone for a long time leads to vigorous trees not growing and causes undesirable phenomena such as alternate bearing.
2. Winter pruning time
Winter pruning is a necessary task that many fruit growers know about, but most of the time everyone prunes immediately after harvest. Pruning immediately actually wastes a great deal of nutrients. The period from harvest to leaf fall is the nutrient accumulation period of the kiwifruit tree, and the leaves can still continue photosynthesis. If the pruning time is too early, it will reduce nutrient accumulation and affect the flowering and fruiting of the coming year. However, pruning too late is also not good. If pruning is too late, it will delay the phenological period of the kiwifruit, reduce the branching rate, and cause deformed fruit, etc. Generally, pruning about 10 days after leaf fall is best.
3. Dispose of pruned branches
When pruning in winter, most branches carry disease and insect pathogens, and the main targets of pruning are also branches such as old dead branches and diseased and pest-infested branches. If they are not cut off in time, these branches will become the source of spread of diseases and insect pests in the orchard the following year. Therefore, when we prune in winter, we must dispose of these branches in time. If they are not disposed of in time, the disease and insect pathogens will regain vitality in the following spring, spread through the branches, and seriously affect planting benefits.
4. Prune decisively
When pruning, be careful not to be reluctant. Many friends cannot bear to cut off those vines that grow robustly and have many branches and leaves when pruning. This causes the tree shape of the kiwifruit tree to become chaotic, forms too many excessive vegetative and vigorously growing branches, and seriously reduces the permeability of the fruit tree. It will not only consume too many nutrients, but also reduce the flowering and fruiting rate of the kiwifruit tree, increase the workload of management, and reduce the economic benefits of planting.
5. Pay attention to the cut bud
Many friends who are planting for the first time will not pay attention to the condition of the cut bud when pruning for the first time. They cut the bud at every head and keep heading back, resulting in too many branches, forming overly dense branches, and making the branches unable to form flowers. When heading back, we should appropriately adjust the treatment method according to the different branches, and determine it according to factors such as variety and growth vigor. We should promptly thin out branches with no growth value, such as long dense, crossing, and overlapping branches, to improve the permeability of the fruit tree.
The above is a brief introduction to the precautions for pruning a kiwifruit tree. Although the pruning work is rather tedious, it is the key to ensuring the healthy growth of the kiwifruit tree, so everyone must master a correct pruning method.
