Plum trees mainly bear short fruit branches and bouquets of short fruit branches, so pruning is generally based on the principle of light cutting and long release, ventilation and light transmission. In the first year, fruit tree shaping was the main task, and the pruning amount was appropriately increased to lay the foundation for high yield. Perennial trees basically take measures such as thinning, shrinking branches and pulling branches to alleviate tree vigor and control vegetative growth.

Pruning period is mainly in summer and autumn, and spring pruning is not recommended. Focus on thinning out over-dense branches, flourishing branches on the back, competing for branches, timely pinching, holding branches and twisting tips, strengthening ventilation and light transmission, and promoting flower bud differentiation.

Extended data:

First, the pruning time:

Pruning of plum trees is mainly carried out in two seasons every year, and the pruning methods in the two seasons are different, namely summer and winter. We continue to look down.

1, summer pruning

Summer pruning needs three to five times. When pruning, you must first know what you want to prune, because the first pruning is in long summer, that is, when spring is about to pass, the first pruning is the buds that are not growing well, the weak buds in the heavy buds, and the ineffective branches. These are all redundant branches. Pruning can bring a lot of nutrition to other branches. When the flowers fall, we prune them for the second time.

2, winter pruning

Winter pruning is only a supplement to the previous pruning, and there is no other purpose, that is, to keep the growth balance of branches and balance the plum trees as a whole.

Second, the pruning method of plum trees:

1, childhood pruning

First of all, plum trees are in the early stage of planting. At the beginning, the plum tree was in a period of vigorous growth, and the growth speed and trend of branches were very fast, and the trunk part was also growing very fast, so the main purpose of pruning was to make it grow into a good tree shape slowly.

Because we want to ensure the early fruit tree yield, we should not make it too hard, so that the branches can be loose, and the whole tree can grow in balance. In addition, some annual short branches can be removed to allow more short branches and middle branches to grow.

2. Prune at the initial stage of the result.

Plum trees will enter the fruiting period after two to three years of planting. At this time, the output can probably be predicted. The purpose of pruning at fruiting stage is to make the overall shape of plum trees grow better and the branches grow thicker and wider. Besides pruning, we should also pay attention to environmental conditions. When pruning, shorten the trunk as much as possible, which can reduce the branch density.

3. Pruning at full fruit stage

After the fruiting period is the harvesting stage, so the purpose of pruning at this time is mainly to improve the transport of nutrients. The nutrient consumption of plum trees in full fruit stage is very large, so it is necessary to minimize the nutrient consumption of some unnecessary branches and use more nutrients in the development of fruits to make them grow bigger and better.

The main thing is to cut off the main side branches, so that the branches of plum trees can grow better and reduce the consumption of some nutrients. The longer the tree is, the more perfect it will be, and the higher its grades will be.

4. Pruning during aging update

Finally, the fruit is pruned after picking. At this time, the tree is in a period of aging and withering, and it will slowly shed its leaves, reduce its fruit yield and wither its branches. At this time, what we have to do is to ensure that the branches can be updated faster and grow new branches, mainly by pruning the trunk, so that the trunk can grow new branches as soon as possible, promote its fruiting ability and grow new fruits as soon as possible.
