How to graft the spade tree, what tree is the queen of spades grafted

For the grafting of spade trees, the general fruit growers are accustomed to using spring and summer grafting. After years of practice, the author can actually graft in autumn and winter, which can increase income. Here's how:

1. Spring grafting: from mid-February to the end of April, the moisture of the rootstock has risen at this time, and it can be cut at 8-10 cm from the ground, and the scion of the variety can be grafted by cutting and grafting. The survival rate of this method can reach more than 95%.

2. Summer grafting: from mid-May to early August, at this time, the sap flows vigorously, the peach tree germinates and spreads leaves, and the new buds are not yet full, which is a good period for bud grafting. Dormant buds can be cut at the lower end of growing branches or germinating branches as scion, and budding can be carried out at a smooth place on the sunny side of the rootstock about 10 cm from the ground.

After two weeks, the interface site is obviously bloated, and some colloids are secreted, and the budding eyes are turquoise, indicating that they have been revived. After 2-3 days, cut the anvil stem outward at the centimeter above the interface, and the cut is horseshoe-shaped to facilitate rapid wound healing. When the new shoots grow to 6-8 cm, insert support columns on the rootstock welt, tie the new shoots, and guide the growth in the upward direction.

If it is found that there is no grafting to survive, a second grafting can be carried out in time.

3. Autumn grafting: from late July to late September, when the leaves of the new bud buds have been formed, the scion with petioles can be cut for bud grafting. Seven or eight days after grafting, if the retained petiole is touched off, it proves that the graft is alive.

After grafting, the anvil can be cut off at the centimeter above the interface before budding in the spring of the following year (late February to mid-March). It can also be planted directly by the semi-seedling method.

4. Winter grafting: From the beginning of November to the end of January of the following year, the rootstock sap has stopped flowing, and the rhizome grafting method can be used at this time. That is, cut off the anvil at the upper end of the rhizome, remove the soil around the rhizome for grafting, gently cover the moist fine soil around and let the scion expose a little after grafting, and then cover with mulch, which plays the role of moisture preservation, heat preservation and drought prevention, so as to facilitate wintering.

In the following spring, the scion will germinate quickly, so the mulch can be removed from mid-to-late March to early April. However, it is necessary to observe on time, and remove the mulch film early for the early germination of the docking ear, and remove the mulch film late for the late germination. In short, it depends on germination.

The buds of the spade tree are connected to the fruit early.

Hello, the Queen of Spades is a variety of Western pear, commonly used grafted trees are the source of the hand sparrow pear and the European pear. These two trees, when grafted, can improve the yield and quality of the Queen of Spades. Wild pear is a common fruit tree, its canopy is widely distributed, cold-tolerant, drought-resistant, barren-tolerant, and adaptable to potato withering.

Although the fruit of the wild pear is not as large as the European pear, it is delicious in taste, rich in hail and rich in early hail, and contains a variety of vitamins and minerals, which help to strengthen the body's immunity. European pear is a high-grade fruit, its fruit is sweet and delicious, the flesh is delicate, rich in nutrition, help regulate the stomach, lower blood lipids, protect cardiovascular and so on. The European pear has a beautiful canopy and is an excellent ornamental tree species for gardens.

In addition to wild pears and European pears, the Queen of Spades can also be grafted with some other fruit trees, such as apples, cherries, etc. Different grafted trees will have a certain impact on the growth and development of the queen of spades and the quality of the fruit, so it is very important to choose the right grafted tree. In conclusion, grafting is a common way of propagating fruit trees, through which the growth rate of fruit trees can be faster, and the fruit quality is better.

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.

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.

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.

Peach trees can generally be grafted all year round, but the survival rate of grafting in spring and autumn is the highest, peach trees are grafted first to pick strong branches, and then prepare the rootstock of the Rosaceae family of peach for grafting, you need to wrap the branches and rootstocks together with cloth strips and plastic film, put them in a cool and ventilated place, and wait for the branches and rootstock wounds to heal and connect.

Peach trees can actually be grafted all year round, but the survival rate of grafting in spring and autumn is the highest, which can make the wounds of branches and rootstocks heal quickly, and the temperature in summer is too high and the temperature in winter is too low, and it is difficult to connect branches and rootstocks together, so it is best to graft in spring and autumn.

First of all, it is necessary to pick the branches that have grown for about 1 2 years and have not suffered from any pests and diseases, and the length of the branches should be between 10 and 15cm, and all the leaves at the upper end should be disposed of, and 2 or 3 leaves should be retained, and then sprayed on the wound to disinfect to prevent pests and diseases during grafting.

In the process of grafting peach trees, it is necessary to choose the right rootstock grafting, and can not choose the rootstock grafting that is not the Rosaceae genus, otherwise the branches and rootstock wounds can not be healed and connected together, and it is necessary to choose mahogany, small trees and other woods to make the rootstock of the peach tree, so that the success rate of grafting is higher.

In fact, the peach tree grafting method is very simple, first use a knife to cut the lower end of the branch obliquely, and then cut the upper end of the rootstock into a 3 5cm deep small hole, the treated branch is inserted into the rootstock, wrapped with cloth strips, plastic film, put it in a cool and ventilated place and wait for half a month.
