How to prune peach plum seedlings? How to prune a newly planted peach tree?

The so-called plastic surgery is to cultivate an ideal high-yield crown structure by means of pruning. The peach-shaped plum saplings have vigorous growth, strong germination power, many branches, strong growth advantage at the top of the branches, erectness, small branch angle, and inconspicuous central stem. In order to promote the opening of the canopy, the branches are reasonable, the forest is formed early, and the fruit is borne early, it is necessary to strengthen the canopy shaping.

The method is: in the first year, cut the top 60-80 cm from the ground at the time of planting or before spring budding. After the first shoot is extracted from the spring budding, all the new shoots on the main stem 30-40 cm above the ground are erased and customized as the main stem, 30-40

According to the requirements of Shengzhou peach-shaped plum tree for planting environment, the light requirements are not strict, and the requirements for air and soil moisture are high, and the yield can be increased by appropriate dense planting. In order to facilitate mechanized management, it can also be planted in a wide row. The planting distance of orchards with good conditions can be 6 4 meters, and the row spacing of 5 3 meters can be used in the narrow slopes and sandy beaches in the north of Tucheng, or in places with a high level of management.

It is planted sporadically in the corners of the field, in front of the house and behind the house, and can be determined by the terrain. Many areas of our province are planted on wide paddy ridges and grow well. Now planting peach-shaped plum seedlings, all pay attention to high-yield dense planting, about 60 per mu, and about 5,000 kilograms per mu during the harvest period, which is a high-yield tree species.

Most varieties of Shengzhou peach-shaped plum have the phenomenon of self-flowering infertility, and must be mixed with other varieties in order to obtain a good yield. The proportion of pollinated varieties is about 10-20% of the main varieties. If the purpose is fresh fruit**, it is advisable to plant early, middle and late ripening varieties, and choose varieties with the same flowering period to pollinate each other.

The flowers of peach-shaped plums are generally in the peak season of blooming in mid-April every year, and the peach-shaped plums in Shengzhou begin to be marketed in mid-July every year, just in the middle of July to mid-August in the scorching summer.

Peach-shaped plum is a small deciduous tree of the Rosaceae family, and its flowering period is from late March to early to mid-April. The fruiting performance of this variety is very good, and the long-fruiting branches, medium-fruiting branches, short-fruiting branches and bouquet-shaped fruiting branches can bear fruit, and there is a cluster-like fruiting phenomenon. The fruit ripens from late July to early August and has a good seasonal consumer market.

Peach-shaped plum is drought-tolerant, cold-resistant, the soil requirements are not strict, the fertilization is made of Ramla special fertilizer, where it is suitable for cultivating peaches and plums can be planted, winter planting should be carried out after the seedlings fall leaves, late November to mid-January of the following year is the best time, and spring planting can be carried out in February to March. Set the dry 35 to 40 cm, put the root system of the seedling into the pit, fill the soil tightly, and water the planting water.

Peach-shaped plum pruning technology points:

First, look at the growth of the tree, soil fertility and tree age, and adopt the corresponding pruning method.

Second, pruning procedures: first cut thick, then fine, control up and down, adjust the direction of branch growth, so that each other does not overlap, there is a certain distance between the branches, do not cross each other, under the influence of typhoon, the branches do not fight with each other, the branches are not densely distributed, and there are branches everywhere, make full use of the land space, each main branch has sufficient light.

3. Adjust flower buds: re-pruning the senescent tree, remove some short fruit branches for the fruit tree, try to retain the bouquet-like branches, let the fruit hang on the main trunk or thicker main branches, and the amount of hanging fruit should be moderate, and all measures should be taken to increase the weight of a single fruit and improve economic benefits.

Fourth, after pruning, the garden should be cleared under the pruning, timely and meticulously spray stone sulfur mixture, generally spray twice, spray 3 5 degrees in winter, spray 0 3 degrees during the tooth eruption period, can eliminate overwintering germs, can also prevent the trunk from flowing gum, and then, reuse base fertilizer, generally 25 50 kg of fertilizer per plant, or 2 kg of cake fertilizer Bo Shemai compound fertilizer. By next spring, depending on the growth of the tree, paclobutrazol will be used.

Some yellowing branches and leaves should be pruned, and the most important thing is that some branches that do not grow fruit must also be pruned in the process, so as to ensure that other branches grow better.

At this time, it is necessary to choose the right pruning time, and be sure to add some bad roots or some weak roots to prune them in time, so that it will not lead to the loss of nutrients from the tree, and it can also ensure the yield of peaches.

The stumps should be pruned in time, and the wilted leaves should be pruned clean, and they should also be pruned to a beautiful shape, and some pesticides should be sprayed in time to avoid being attacked by insect infestations.

Main branch pruning: In the process of young tree growth, it is necessary to select well-developed branches as the main branches, and the length of the main branches is about 70cm, and then the top operation is carried out. 3-4 branches are usually left under the main branch cutting, the dorsal branches and dorsal lower branches are removed, the flat oblique branches are retained at 40cm, and the removed branches are left with basal buds to avoid empty branches.

Pruning auxiliary branches: The main branches of annual peach trees need to be retained to ensure the growth of the main branches, and their growth is controlled by retraction, and the fruit branches are pruned according to the distance of 20cm on the same side, and the over-dense fruit branches are thinned.

Pruning side branches: The side branches on the main branch also need to be pruned, choose one-year branches (or secondary tips or previous year branches), and the length of pruning is shorter than 60cm. To ensure that the side branches can bear normal results, the branch angle between the side branches and the main branches is about 60 °, stretching outward obliquely, the length of the pruning is slightly shorter than that of the main branch extension, and the cut buds generally leave the outer buds.

Avoid the disadvantage of overlapping the side branches and the main branches causing mutual shade.

Pruning group: Pruning should be combined with cultivation and utilization. The degree of pruning should be reasonably controlled for large branches, and the degree of manual stimulation pruning of the extended branches should be heavier than that of the side branches, and attention should be paid to the direction of the cutting buds and the extended branches to ensure their normal growth.

The ability of large and medium-sized branches in the canopy is reduced and the base is rejuvenated, and the weak branches can be thinned.

At the seedling stage, the young leaves and shoots grown at the top should be removed during the peach tree seedling period, and the branches that grow too long should be truncated by one-third; In the early fruiting stage, after the peach tree enters the first fruiting stage, it is necessary to prune off the branches that stretch too messily and densely; During the peak fruiting period, it is necessary to prune off the branches with poor growth and poor growth in time, so that the nutrients can be concentrated on the growing and robust branches.

In the peach tree seedling stage, it is necessary to take the pruning method of topping for pruning, you can use the sterilized sharp scissors to prune off the buds and tips that grow at the top of the peach tree, and cut off the branches that have grown too long by one-third, so as to control the growth height of the branches and promote the peach tree to germinate new branches for fruiting.

After the peach tree enters the first fruit stage, the pruning is mainly based on shaping, pruning off the too messy and dense branches on the peach tree, improving the ventilation and light transmittance between the branches and leaves, and finding that the diseased branches need to be cut and destroyed in time, so that the peach tree can grow healthily, and after the pruning is completed, it is necessary to spray carbendazim solution to the wound for disinfection.

In the full fruiting period of peach trees, it is necessary to take the pruning method of weak retention and strong retention, prune off the branches with poor growth and poor growth, so that the nutrients are concentrated to the branches that grow strong and wide, and the damaged branches need to be inspected from the base to reduce unnecessary nutrient consumption.

After the peach tree bears fruit, the trunk of the first fruit needs to be pulled to make the angle open larger, and the newly extracted, overgrown branches should be pruned in time, and when the branches reach 30 cm, they need to be topped in time to control the growth length, so as to improve the yield and quality of peach tree fruits.

The peach tree is a small deciduous tree, and in the process of peach tree growth and management, poor management will easily cause crazy growth, or even only flowering and not bearing fruit. Today, let's talk about one of the most important things in the peach tree management process - pruning skills!

Juvenile trees.

First of all, it is necessary to select three branches with uniform orientation and basically the same growth as the main branches. Generally, the length of the extended chain bend tip is 50 60 cm, and the secondary tip that has been topped in summer can be appropriately shorter. If the orientation of the three branches is uneven, the method of pulling the branches can be adopted to ensure that the distribution of the large branches is reasonable; The angle of the base of the large branch is 50 60 degrees as the standard, and the method of pulling or bracing can be used if it is too large or too small; The rest of the twigs can be appropriately grown and left for more; The branches that are competitive with the three major hail should be removed.

Three-year-old peach trees.

The key to the extension of the tip is to choose a good side branch, and leave a side branch on each large branch; The three lateral branches should be left in the same direction; The position of the branch is about 40 to 50 cm above the base of the large branch; The angle should be greater than the main branch, and the growth should be smaller than the main branch; The direction should be on the anticline side, and if it does not meet the requirements, it can be pulled manually; For the rest of the fruiting branches, little or no remains on the back, and more on other parts; Other large branches that may affect the tree's potential must be thinned and cut off; Ensure the growth advantage of the three main branches and the side branches.

Four-year-old peach tree.

It has entered the fruiting period, and the extension tip can be extended by a small head change method; Proper control of apex advantage; And focus on cultivating the second side branch, the second side branch is 60 80 cm away from the first side branch, and should be selected in the opposite direction with the first side branch; At this point, the tree shape of the three main branches and nine heads of a peach tree is basically a foregone conclusion.

Adult trees.

If the growth is vigorous, the extension tip continues to take a small head change method, one is conducive to controlling the height of the peach tree does not exceed the meter, and the other is to control the top advantage to ensure the reasonable germination of the middle and lower branches, and prevent the middle and lower parts from emptying; Secondly, the growth of the dorsal and upper branches in the middle and upper parts should be strictly controlled to prevent "trees in trees" from affecting the light. The dorsal branches of the upper part are basically sparse; The long branches in the middle should be used to cultivate the branch group, and the methods of climbing, pulling, twisting, and shrinking should be adopted.

Weak trees for old age.

Pay attention to the pruning method of rejuvenation and renewal, with the principle of more interception and less sparseness. Generally, 8 10 buds are left on extended shoots and long fruit branches; 4 6 buds of medium fruit branches; 2 3 buds of short fruit branches and weak branches; Retract the thin branches that have been planted in the previous year. Fewer branches and more openings are conducive to the revival of the tree.

The pruning methods of peach trees are divided into thinning, pinching, short cutting, long tip pruning, and germination pruning.

1. Thinning

Sparse pruning is to prune off all the excess branches at the root of the peach tree to avoid poor permeability of the peach tree. Sparse pruning is generally to cut off peach trees that are too densely grown, overlapping branches, etc.

2. Pinch the chain of songs

The main purpose of pinching the branches is to inhibit the growth of new shoots of peach trees, control the vegetative growth rate, and promote the growth of new branches of peach trees in the future. It is commonly used for young tree shaping and adult tissue culture.

3. Chopping

In order to improve the nutrient absorption of branches, improve growth ability, and promote the growth of new shoots, Chen Zheng cut off about 1 3 branches.

4. Long tip pruning

When pruning, pay attention to the age and growth period of the peach tree. For branches within a year, we should not re-prune. We can cut and throw them appropriately.

After pruning, the germination ability and growth ability of the shoots increased, but the growth decreased. However, its growth is large and the nutrients are dispersed, which can promote the differentiation of flower buds, flowering and fruiting.

5. Germination and pruning

When a peach tree sprout germinates, it is necessary to remove the excess shoots from the branches, which are mainly competitive clumps of buds. Typically, half of the buds are wiped off, and then the growth direction is adjusted appropriately during the molding process.

During the growth period of the peach tree, it is necessary to pluck the top of the plants that are too tall, in order to remove the top advantage and control the height of the peach tree, you can cut off the top branches and let the branches develop to the surroundings to form a round crown, which is conducive to increasing light and ventilation. 2. When pruning peach trees with thinning leaves for peach tree pruning, it is necessary to cut off the over-dense branches of the plant, because the growth of peach trees is vigorous, after a year of growth, the branches will become disorganized, at this time, it is necessary to cut off the branches that affect the tree potential such as over-growth, crossing, overlapping, etc., and only retain the thick and sparse branches to improve the fruit-bearing rate of the plant. 3. Pruning the peach tree with diseased branches In the process of peach tree pruning, it is necessary to cut off the injured branches and diseased branches in time to reduce the occurrence and spread of pests and diseases, change the lease and retain the branches that develop horizontally around the tree, so as to expand the area of the canopy, which is conducive to improving the ventilation and light transmittance between plants.

Topping: During the growth period of the peach tree, it is topped to control the plant height and balance the state of the peach tree. Thinning of branches and leaves:

Cutting off densely growing, crossing, overlapping branches and reducing nutrient consumption is conducive to improving the fruiting rate of peach trees. Pruning diseased branches: remove wounded branches and pest-mested branches to reduce the occurrence of pests and diseases.

1. Topping

During the growth period of the peach tree, it is necessary to pluck the top of the plant that grows too high, remove the top advantage for it, in order to control the height of the peach tree, you can cut off the top branches, let the branches develop around, form a round crown, which is conducive to increasing light and ventilation.

2. Thinning branches and leaves

When pruning for the peach tree, it is necessary to cut off the over-dense branches of the plant, because the growth of the peach tree is vigorous, after a year of growth, the branches will become disorganized, at this time, it is necessary to cut off the branches that affect the tree momentum such as over-dense, crossing, overlapping, etc., and only keep the thick and sparse branches to improve the fruit-bearing rate of the plant.

3. Prune diseased branches

In the process of pruning peach trees, it is necessary to cut off wounded branches and diseased branches in time to reduce the occurrence and spread of pests and diseases, and to retain the branches that develop horizontally around to expand the area of the canopy, which is conducive to improving the ventilation and light transmittance between plants.
