In order to make ripe peaches have a good color, how do fruit growers prune?

Pruning branches that shade the fruit from sunlight or pruning small, unripe fruits will make the ripe fruit grow better.

Pruning is to make the peach tree have good ventilation and light transmittance, so that the fruit can be fully exposed to the sun and achieve the effect of uniform coloring. Therefore, it is necessary to cut off those branches that block each other and do not bear fruit to reduce the nutrient consumption of fruit trees.

After the peach tree is picked, it has to face a lot of things, because the peach tree grows a lot, the branches are naturally branched, and only thinning can make the crown balanced, and peach tree pruning can control the shape of the tree and ease the tree's momentum.

It is a semi-lignified part of the erect shoot, which is twisted by hand, so that the xylem and phloem are sprained at the same time without breaking. The sprained shoots droop or flatten, usually about 30 cm long and twisted at 15 cm from the base. Twisting the branches can transform the long branches into fruiting branches, improve the light conditions, ease the growth of the tree, and prevent the growth of the branches.

There are many varieties of kiwifruit, and a variety of varieties of development period is very different, after the fruit is fertilized, it takes 130-160 days to develop to maturity, the maturity period can be from August to October, and the planting area is wider, basically you can see kiwifruit on the market for a long time.

The color of kiwifruit fruit does not change much during the whole growth period, and there is no aroma, there will be a certain difficulty in harvesting, if it is harvested too early, the fruit is not rich in nutrients, not only easy to ferment and deteriorate, but also the fruit is small and light and astringent; It will affect the quality, and if the harvest is too late, the fruit will be too ripe, softened and deteriorated, and the peel will shrink and be unsightly. The storage period is not long, and it may also encounter the hazards of low temperature weather.

The original color of the peaches is red.

White peaches and yellow peaches are all lighter in color because they have a bag on the peaches and can't shine in the sun.

But as long as 15 days before ripening, remove the bag, it will be sunburned red and turn into hearts.

Some white peaches are red, which means that the shading of the bag is not good, or part of it is damaged.

The peach tree seedlings used as rootstocks are thick and strong to improve the survival rate of seedlings, so the seedlings should be topped when the seedlings are 25 30cm high, and the seedlings can be transplanted when the thickness required for grafting is reached. When transplanting, small seedlings can be bare roots or mud, and large seedlings need to bring soil balls to reduce the damage of seedling roots.

About 40% of the total number of branches are cut each year. In this way, more new branches can grow, and some old branches will not bear fruit, and it is a waste of nutrients to stay there. Remove the old branches and leave the more tender ones, which look pale pink.

Cut off some branches that never get sunlight and are dead.

Pruning the tree shorter will encourage outward growth rather than upwards.

In order to produce large, sweet fruit, about 90 percent of the fruit already on the tree must be removed.

If it's a mature peach tree, we need to shape the peach tree and just leave four to six old branches.

All pruned branches should grow at a 45-degree angle, too flat or too upright, and the branches will easily break when they bear fruit.

1. Be sure to prune the tree shorter, which will encourage it to grow outward, not upward. 2. In order to produce large and sweet fruits, about 90% of the fruit already on the tree should be removed. A healthy tree will often produce too much fruit to raise it all on its own, so it's important to remove most of them for optimal yield.

3. When pruning mature peach trees, it is necessary to shape the peach trees. This is the most important step in pruning, and it determines the growth form and yield of the tree. You only need to leave four to six old branches, and the rest can be cut off.

4. All pruned branches should grow at a 45-degree angle. If it is too peaceful or too li, the branches can easily break when they bear fruit. 5. If you look down, the branches wrap around the peach tree, making the trunk an open center that looks like a doughnut or ring.

Summary. If there is no fruit to stay on the side branches, the fruit of the lower branch can also be left, the method is the same as leaving the fruit of the side branches, first give priority to the side branch fruit, because the side branches absorb more nutrients, the lower branches block the sunlight for the side branches, the branches are thinner and the peaches do not have sufficient sunlight, and the quality and sweetness are not as good as the fruits of the side branches, so it is best to give priority to the side branch fruits.

Is it better to leave the peach with fruit, the side peach with the branches, or the underside of the branches?

If there is no fruit to stay on the side branches, the fruit of the lower branch can also be left, the method is the same as leaving the fruit of the side branches, first give priority to the high lead of the side branch fruit, because the side branches absorb more nutrients, the lower branches block the sunlight for the side excited branches, the branches are thinner and the peaches do not have sufficient sunlight, and the quality and sweetness are not as good as the fruits of the side branches, so it is best to give priority to the side branch fruits.

Natural cup-shaped bai

Cultivation of the canopy: After transplanting the grafted seedlings of one year, the main stem is left 1 meter high, the top tip is cut off, and the cut bud is left back to the strong bud. New branches are continuously drawn out at the answer site below 1 meter, and can be selected as the main branch.

Generally, the new branch at 30-40 cm above the ground is left as the first main branch; 20-30 cm above the first main branch, select a new branch as the second main branch; At a distance of 1 meter, the new branch extracted from the cut bud is the third main branch. The three main branches should be evenly distributed around the main trunk, and it is best not to grow in rotation. During summer pruning, remove the upright branches on the main branch, the sprouting tiller branches on the main trunk and the rootstock buds that germinate on the rootstock, so as not to affect the growth and early formation of the main branch.

In the second winter, each main branch is shortened, and the bud is cut to leave strong buds, so as to cultivate the extension branch of the main branch. In addition, choose suitable side branches on each main branch. It should be noted that the side branches of the same level should be left in the same direction to avoid the side branches crossing each other and affecting the tree shape and ventilation and light transmission.

Cultivation of natural heart-shaped canopy: After transplantation, annual grafted seedlings are dried at 40-60 cm. In the shaping zone above the fixed stem height, generally choose 3 main branches (a few also choose 4 or 5 main branches), the position of the main branches should be evenly distributed, and the central stem should be kept at about 45°, and grow radially.

The rest of the branches were all removed. In the second winter, the main branch is shortened at 30-50 cm to prepare for the development of lateral branches. Remove the other branches, the tillers on the trunk, and the buds on the rootstocks.

This creates a natural heart-shaped crown.

1. Peach tree pruning plan.

After the tree is harvested, the peach tree must be pruned once. If it is not carried out for a long time, the yellowing or death of new branches and leaves will occur in the lower shade closed places, resulting in disconnection and affecting the yield of the next year.

Smart peach farmers prune the peach fruit immediately after picking, so that the tree can achieve ventilation and light to grow robustly, and create good development conditions for raising flowers. However, some peach farmers lack experience, the technology is not up to standard, and the grasp is not in place, which is easy to cause mistakes in the method and promote the germination of buds, which seriously affects the formation of flower buds.

With the same amount of trimming, a little detail is problematic and the two effects are diametrically opposed. When done in place, fruiting branches rarely bud into buds. If you don't do it properly, the branches and buds will sprout into tender shoots, and even if there are flower buds, the fruit will not be too good the next year.

It is worth summing up experience, correcting technical mistakes, and doing the pruning in place to reduce unnecessary losses.

Second, the peach tree fertilization program.

Peach trees are more tolerant to barrenness, and the young tree stage needs less fertilizer, and the amount of fertilizer applied to adult peach trees should be applied with nitrogen (N) kg, phosphorus (P205) kg, and potassium (K2O) kg per 100 kg of fruit produced.

Fertilization is divided into two kinds of basal fertilizer and top dressing, basal fertilizer is generally applied after the fruit harvest in autumn, the dosage is 2 3 times of the yield, mainly organic fertilizer, with the application of inorganic fertilizer, generally 3000 3500 kg of farm fertilizer per mu or 400 450 kg of commercial organic fertilizer, 13 17 kg of diammonium phosphate, 6 kg of urea, 5 kg of potassium sulfate. There are three application methods: one is the outer canopy annular furrow application (suitable for young trees); the second is the extra-canopy radial furrow application (suitable for trees in the peak fruiting stage); The third is to sprinkle the whole garden (suitable for densely planted mature peach orchards).

If basal fertilizer is applied in early spring, it should be applied as early as possible. When the soil temperature is stable at 4 5, the root system of peach tree begins to move. When the soil temperature rises, the root activity accelerates, and if you do not pay attention to protecting the root system when digging a fertilization ditch, a large number of root injuries will affect the absorption of the root system.

Top dressing is generally 2 to 3 times a year, the first germination period: generally started about 2 weeks before germination. In order to supplement the lack of nutrients in the previous year, make the flowering neat, improve the fruit setting rate, and at the same time expand the leaf area and promote the growth of new shoots.

The fertilizer is mainly available nitrogen fertilizer, and about kilograms of urea are applied per plant;

In the second fruit hard core stage, this topdressing can promote embryo and nuclear development, germination and differentiation, fruit expansion and lay the foundation for the next fruit. Some Ribery Yanwo water-soluble fertilizer can be applied;

Fertilization after the third fruit harvest can supplement the consumption of the tree, strengthen the nutrient accumulation in autumn, and improve the overwintering ability. The type and amount of fertilization were the same as those of the second application.

It can't be pruned, it's not the growing season at this point.

It is best to prune after the fruit has been harvested.

Stub pruning, pruning peach branches by 1 3 or half.

Most of the peach trees in the peach producing area are pruned in winter by long-term pruning techniques, which are fast, stable and fruit-set. It subverts the traditional concept of stub pruning and pruning. It has been unanimously recognized by expert peach farmers.

Through stub pruning, the peach branch is cut off 1 3 or half, the fruit thinning is much faster, and the labor of the fruit is reduced at least several times, which not only saves labor costs, but also saves the amount of fertilizer.

Expand your knowledge - Fertilization methods for peach trees after fruit picking:

1. During the growth of the fruit, the peach tree consumes a large amount of tree nutrients, and the nutrients in the body are lacking, so it needs to be supplemented in time. Top dressing should be carried out in time to restore the tree's potential.

2. After the peach tree is picked, it is the nutrient accumulation period, at this time, the top dressing can make the tree strong, the flower buds are full and full, and lay a good foundation for the bumper harvest in the coming year. Top dressing is mainly livestock and poultry manure, straw and soil miscellaneous fertilizer, with an appropriate amount of high nitrogen type and trace elements such as iron, zinc and boron.

The topdressing method can take the method of digging a radial trench, and the length of the radial trench should exceed the projection area of the tree. Foliar fertilizer can also be sprayed, and ribery Yanwo amino acid foliar fertilizer can be used to improve plant disease resistance and stress resistance.

It is advisable to set the fruit reasonably. The first fruit thinning should be 1 3 more than the final fruit retention, first thinning the combined fruits, deformed fruits, small fruits, verticillal fruits, fruit on the back of fruit branches and diseased fruits, and retaining the middle and upper fruits of the branches, good fruits, long fruits, fruits on both sides of the branches and fruits growing downward.

The first time is carried out when the young fruit grows to the size of the apricot kernel, the second time when the fruit grows to the size of the green apricot fruit, the fruit is completed before the hard core, and the second time the fruit is thinned is also called the fruit.

It is best to leave the fruit at the middle and upper part of the long fruit branch and the fruit at the tip of the medium and short fruit branches, and pay attention to the evacuation distance, so that the fruit forms a triangular arrangement to avoid crowding together.

The main economic cultivation areas are in North China and East China, and the more concentrated areas are Haidian District, Pinggu District of Beijing, Jizhou District of Tianjin, Mengyin, Feicheng, Yidu and Qingdao in Shandong, Shangshui and Kaifeng in Henan and Funing in Hebei.

It is native to China and is widely cultivated in various provinces and regions. It is cultivated all over the world.

The more important varieties of peaches are: nectarine, peach, birthday peach, and peach. Among them, nectarines and peaches are cultivated as fruit trees, Shouxing peaches and peaches are mainly for ornamentation, and Shouxing peaches can also be used as dwarf anvils for peaches.

Branches should be pruned, reproduction management should be done, care requirements should be paid attention to, and regular watering should be carried out to ensure the fertility of the soil, so that fruits can be produced.

Be sure to prune the branches and leaves of the peach tree regularly, to avoid the peach tree growing too vigorously, and sometimes to increase the light transmission of the peach tree. Organic fertilizer should be applied in a timely manner, and vegetables and fruits should be managed.

The peach tree is a common cash crop in the north. After the peach tree blooms, it is important to pay attention to the care of the flowering period and prune the old branches regularly. In addition, the peach tree should be supplemented with nutrient solution.
