How to operate peach tree grafting? How to graft peach trees

There are 4 main methods of grafting peach trees, and today I will talk about the budding method of peach trees. The bud grafting of peach trees grows very quickly, and the fruit can be hung in the second year of grafting, and the fruit can enter the period when the fruit is relatively vigorous in three or four years. These advantages are indispensable for peach tree cultivation, and its grafting technology is relatively simple.

How to graft between the buds of a peach tree, the first step is to choose the right rootstock.

The rootstock should be selected to grow relatively robust and free of diseases and pests. For peach seedlings with stem thickness of more than centimeters, do not choose branches that are too thin. Then select the branches used for scion, and choose the best peach trees that have grown for more than three years to grow new branches.

The bark of these branches should be smooth, and the new ones should grow more robustly. At the same time, it should be free of pests and diseases, full of flower buds, and the stem thickness should be consistent with the thickness of the selected rootstock.

We need to choose a good time for grafting, which is generally grafted from late March to early April every year. Since the climate and environmental temperature are different in different places, it is necessary to properly judge the most suitable grafting time. It can also be judged by the growth of the peach tree, when the sap of the peach tree appears to flow in large quantities.

The buds are 3 to 5 days before opening, and the buds grow to about one centimeter, which is the best time for peach tree grafting.

In addition, it is also necessary to prepare some plastic bags for grafting. The third step is to select a fuller bud point on the rootstock, and first use a knife to circumferentially cut one centimeter above and below the bud point, which needs to reach the xylem layer of the branch. Then make a vertical cut on the opposite side of the bud to connect the bark and buds, and then gently pull it off.

When the branch is circumferentially cut again.

The action must be fast and light, and do not damage the wood core at the bud bag. Circumferentially cut a bud of exactly the same size on the scion, and be sure not to damage the spores. At this time, gently press the bud bud peeled off the scion in the original direction to make it stick tightly to the rootstock.

The parts that are in contact should be completely matched, at this time they should be wrapped in a plastic bag, and the buds on the rootstock should also be wiped off.

At this time, the grafting is completed, and a certain amount of attention is also required, and the sprouts born of the rootstock should be erased in time after grafting. It can make the nutrient supply more concentrated, and the bud grows vigorously. It is usually checked every other week until the grafted shoots have grown to 20 cm.

Tie a stick to the rootstock and tie the new shoots to the pillar to prevent them from being broken by the wind. Once the grafted wound is completely healed, the plastic bag can be removed.

At the same time, the newly grafted branches are susceptible to pest and disease infection, and 20% of 20% of the quick-killing butadiene emulsifiable concentrate can be sprayed with 50 kg of water. You can also use stone sulfur mixture to evenly spread on the rootstock to prevent the invasion of pests and diseases, and carry out topdressing in an appropriate amount. You can use urea solution to spray two or three times, or you can use 1% phosphate fertilizer to spray 1 2 times, each time after the top dressing needs to be watered.

When the peach tree is grafted, the skin grafting method can also be grafted by the bag method, the bark of the peach tree is not easy to break, it is more appropriate to use this grafting method, and the effect after grafting is also good, and the plastic strip can be tied after grafting.

Peach tree grafting should be carried out in spring and autumn, picking the branches with good growth, leaving 2-3 leaves. The rootstock can use myrtle, and the grafting of the same family is easier to survive.

Peach tree budding can be done using the method of square budding.

Before grafting, the rootstock needs to be trimmed, and the rootstock can be repaired, so that it is more convenient for the growth of the peach tree in the later stage, and the part of the budding is generally selected within 10 cm from the main branch of the peach tree.

When choosing budding, it is necessary to select a healthy and good quality peach tree as the mother tree, and select the full leaf buds that grow on the branches of the main branch of the rootstock with similar thickness and size as the budding. Use a sharp knife to cut a knife at the top centimeter of the selected bud, and the lower part is about a centimeter away from the petiole of the hail, and the strength needs to be deep into the wood, and then cut vertically on the left and right sides of the leaf bud, each with a knife, and the force is also deep into the wood, and then gently remove the leaf bud.

Precautions for peach tree grafting

1. The grafting time of peach trees can generally be carried out in spring, autumn and summer every year, but spring and summer are the most suitable among these three seasons. Spring is usually held from April to June each year. This time point is the time when the vitality of the peach tree is the most vigorous, and it is also the time when the grafting success rate is the highest.

2. Peach trees belong to the Rosaceae family, so if you want to graft a good peach tree, it is best to choose plants of the same family as the peach tree, such as mountain peach tree, apricot tree, plum tree, cherry tree, etc., which can be grafted with peach trees.

Make an incision deep into the xylem at a distance of 10 cm from the main branch of the rootstock, and then place the bud pieces in it, fixed with tape. 3. Precautions: Rainproof treatment should be carried out in rainy weather to avoid rainwater pollution of the interface.

1. Grafting time

Grafting peach trees can be carried out in spring, summer and autumn, the spring grafting time is from April to June every year, when the peach tree grows vigorously, and the summer grafting time is from May to August, at this time the sap of the peach tree is highly fluid, and the autumn can be grafted in July and September every year, and the plant survival rate is high at this time.

2. Grafting method

Grafted peach trees can take the bud grafting method, first prune the rootstock to ensure that the plant shape is full, then select the rootstock 10 cm away from the main branch to draw an incision, and then the bud with full buds and the incision are fully fitted, and the tape can be tightly wound.

3. Precautions

When grafting peach trees, the incision must go deep into the xylem, so as not to fuse the rootstock and the bud, after the grafting is completed, check the grafting interface regularly, if the bud is fresh, it means that the grafting is successful, the bud is black, it needs to be re-grafted, and rainproof measures should be taken in rainy weather to avoid the interface being polluted by rain and rotting.

1. Peach tree planting can be divided into spring and autumn planting, among which spring planting is generally carried out after the soil thaws and before germination, which is conducive to slowing down the seedlings and will not cause frost damage to the seedling roots; Autumn planting is generally carried out after the leaves fall in autumn and before the soil freezes, which is conducive to early budding in spring. The best grafting time is in mid-March in spring, followed by mid-to-early September in autumn, which is too early to produce gelatin, and too late to have a low survival rate. In production, more farmers prefer to graft in spring and summer, spring is generally between February and April, and summer is between May and August, and the survival rate is relatively high.

2. The skin with rootstock should choose the peach seedlings that grow robustly, have no diseases and pests, and the stems are thick to more than centimeters, which has the characteristics of fast growth and grows extremely fast after grafting. The new branches on the peach trees of excellent varieties that have grown for more than 3 years should be selected for the scion, and the branches and seedlings should be smooth and delicate, the growth is strong, there are no diseases and pests, the flower buds are full, and the stem thickness is consistent. In this way, it is conducive to the combination of cambium layers and improves the survival rate during grafting.

3. Prepare grafting tools, plastic bands, knives, etc., there are many methods of grafting in production, and the commonly used is the bud grafting method. Select a bud eye on the rootstock, peel it once with a knife 1 cm above and below it, go deep to the xylem, and then peel off the bark and bud eye together. Then use the same method to cut a bud bud of the same size on the scion, align it and press it into the peeled bud bud, fit it tightly, and then tie it firmly with a plastic wrapping strip.

4. After grafting, it is necessary to check every 7-10 days to erase the bud eyes of the rootstock mountain in time, so as to concentrate the nutrients and make the buds grow vigorously. In addition, after the wound of the grafting site is healed, the plastic bandage strip can be removed, so as not to spill the injury, after the grafting survives, the plant grows vigorously, the amount of fertilizer is large, and it is necessary to fertilize in time, mainly nitrogen fertilizer, you can spray foliar fertilizer, and promote the growth of the plant to hold the bucket quickly.

The method of grafting peach trees should grasp the grafting time and choose the right tree.

Peach trees can be grafted in spring, autumn and summer, with spring and summer being the most suitable. Spring is generally in April to June every year, summer is generally in May to August every year, and autumn grafting is generally selected from late July to late September every year. Peach trees are the most vigorous in spring, and the survival rate of grafting is very high.

In summer, the sap flow of peach trees is most vigorous, and the new buds have not yet grown to full capacity.

If the surface of the scion should be smooth, robust, full of flower buds and free of diseases and insects, new branches on the peach tree that have grown for more than 3 years should be selected. The rootstock should choose a strong stem and vigorous growth, so that it grows quickly. The wound can also be better integrated after grafting, thus improving the survival rate.

The rest of the methods

After that, wipe off the germination tillers on the anvil in time to promote nutrient concentration and vigorous budding, generally checked once every 7-10 days. In order to ensure the healthy growth of plants, it is necessary to apply an appropriate amount of chemical fertilizer in time, and the fertilizer is mainly nitrogen fertilizer, and foliar fertilizer can also be sprayed. The urea solution used in the early stage is sprayed 2-3 times, and then sprayed with 1% phosphorus bridge rental fertilizer filtration leaching solution 1-2 times in the cautious elimination period, and watered once after top dressing.

Peach tree grafting mostly uses the bud grafting method, first of all, select a bud eye on the rootstock, peel it 1cm above and below the bud eye, and the depth of the ring peel should reach the xylem, and then peel off the bark and the bud eye together. Then, using the same method on the scion, cut a bud of the same size, press it into the position where the bud was peeled, fit it tightly and wrap it with a plastic bag.

The grafting method of peach tree seedlings is as follows: the peach pit used as a grafted rootstock completes the vernalization stage in the wet sand, so that the hard shell is easy to crack and easy to germinate, sowing in March and budding in early April. There are seeds stored in the sand, peach seedlings can be sown in autumn, choose higher terrain to cultivate peach seedlings, seedlings grow rapidly, seedlings can grow 20-30cm high in autumn.

The bud grafting is generally in mid to late August, and the T-shaped bud grafting method is mostly used, or the grafting is carried out in early April in spring, and the cutting, ventral grafting and splitting methods are mostly used. In this way, the grafted peach seedlings with strong adaptability and good performance are basically over, and the rest is fertilizer and water management and selling seedlings.

You can find some peach trees that grow better, and then pick them and graft them onto other saplings, which can achieve such an effect.

The grafting time of peach trees is generally selected in July and August every year, that is, around June of the lunar calendar. The rootstock can be selected from mountain peach or peach seedlings, and sown and cultivated in advance. There are several methods of grafting, which can be grafted by cutting grafting, bud grafting, ventral grafting, and leaf grafting, and can be selected according to the situation.

After grafting, it can add water to the peach tree, which can improve the survival rate, and wipe it clean in time when there are sprouting tillers.
