Bayberry grafting technology, what rootstock seedlings are used for bayberry grafting

Bayberry is native to Yuyao, Zhejiang, and is now in East China.

It is distributed in Guangdong, Guangxi, Hunan and other regions. Bayberry has good edible value and medicinal value, and has the effect of relieving cough and stomach nausea. The taste of bayberry is very good, with moderate sweetness and sourness, and it can be eaten directly, or it can be processed and processed into candied fruit.

Dried bayberry and other foods.

The growth of bayberry also needs to be grafted, so what rootstock seedlings are used for bayberry grafting, let's explain it now. When grafting bayberry trees, you can choose to sow bayberry seedlings or wild seedlings. Because poplar seedlings are relatively easy to survive, there is no restriction on the type of rootstock seedlings that can be chosen.

However, it is best to choose poplar seedlings, so that there is a bucket source conducive to the growth of tree finch seedlings.

Then, there is a certain limit to the grafting time, so the time must be grasped. Then it is better to carry out it in the spring, and it is the best to carry out it in the period from mid-February to mid-March, because at this time, grafting bayberry seedlings has a greater chance of survival, and the growth is relatively fast, and it is also very helpful for the growth of bayberry seedlings in the later stage. Then the latest grafting should not be later than the Qingming time, otherwise it will seriously affect the survival rate of grafted seedlings.

Then after grafting, it is necessary to start to remove germination and erase the germination in time to facilitate the survival of the sapling. Then there is the retention of auxiliary branches, and then the beginning of the bag, the breaking of the membrane, and then the topping, choose two to three branches, and repeatedly pluck the tops when they grow to 20 centimeters, which is beneficial to the canopy.

The development of the formation. Then, it is also necessary to whiten the trunk. Finally, pillars need to be erected to protect the saplings from being broken by the strong winds.

The current year's shoots are selected as cuttings, the bottom is cut into a wedge shape and inserted into the vertical incision of the rootstock. 3. Post-management: within one month after grafting, wipe out the young shoots of the rootstock to save nutrients.

1. Grafting time

Bayberry grows vigorously in a mild climate environment, grafting bayberry can be carried out in spring, when the temperature rises, which is conducive to improving the survival rate of grafting, and the southern region should be grafted in January and February every year, and the northern region should be grafted in February and March every year.

2. Grafting method

Grafting bayberry should choose the branches of the current year as the scion, cut the leaves off, cut the bottom bark, and cut into a wedge, then choose the trunk that grows thick as the rootstock, choose a smooth place at a position of 10 cm from the ground, and then split it vertically to the cutting surface, and finally insert the scion into the incision and tie it with plastic film to fix it.

3. Post-grafting management

Within 30 days after grafting, the young shoots germinating on the rootstock should be erased irregularly to improve the survival rate of grafting.

1. Adopt the cutting method, that is, use the multi-headed, long spike, and horseshoe-shaped cutting method, and wrap the scion and interface with film. The height of the graft should be controlled below 2 meters, and the diameter of 3 to 6 cm should be selected on the side branches, and the number of auxiliary branches should be retained, and the buds should be evenly distributed in the canopy, and each bud should be more than 50 cm apart, so as to avoid dense branches and premature depression.

2. The interface and scion interface should be selected in a smooth and disease-free place, the cross-section should be smooth, and the grafting knife should be cut to about 3 cm. The scion is more than 8 to 9 cm long, 3 to 4 cm long section along the lower part is slightly woody, the dorsal cortex of the cut surface is flattened off 1 to 29 cm short cut surface, the scion cut surface is inserted into the xylem of the incision, and the scion is exposed with a white line, one side should be close to the phloem, so that the cambium layer of the two is densely connected together, and the interface and scion section are wrapped with a 4 cm wide film strip to avoid water evaporation and affect the survival rate.

3. The high part of the meditation should be low rather than high, so as to facilitate growth and achieve the purpose of dwarfing the tree at the same time.

Bayberry trees are generally grafted between February and April, and the rootstock can be Dongkui bayberry, and before grafting, you can choose the mother plant that is more than 7 years old, and cut its robust branches as scion. Cut the scion into a wedge, cut a small hole on the side of the rootstock with a smooth cross-section, insert the cut scion into the incision of the rootstock, and then tie it with plastic film.

Grafting method of bayberry tree.

The propagation mode of bayberry tree is grafting propagation and sowing propagation, grafting propagation is generally carried out between February and April, and Dongkui bayberry can be used as rootstock. The growth of Dongkui bayberry is good, and the stress resistance is strong, which can improve the survival rate of fruit trees and enhance the disease resistance of fruit trees. Before grafting, choose bayberry trees that are more than 7 years old and cut their strong branches.

The cut branches are used as scion, the length of the scion is controlled at about 8 cm, and after the leaves are cut off, the bottom of the scion is cut into a wedge shape and placed in a cool place. Choose the smooth side of the rootstock and cut it 8 9 cm from the ground from the rootstock, making sure that the cut is flat. Make a vertical cut on the smooth side of the rootstock to expose the white woody part.

After the rootstock is cut, the cut scion can be inserted into the incision of the rootstock, and it can be tightly tied with plastic film so that the scion is close to the wooden part of the rootstock. After grafting, the joint part of the rootstock can be cleaned with diluted carbendazim solution for sterilization and disinfection. After disinfection, it can avoid bacterial infection of the plant and improve the survival rate of the plant.

After the scion survives, the film can be removed after a period of maintenance, and the plants should be given sufficient light, water and fertilizer to promote plant growth. Diseases and insects will invade the young shoots and young leaves of bayberry trees, during the maintenance period, every 15 to 20 days, the trees can be sprayed with carbendazim or chlorothalonil solution once, which can avoid the plant from being attacked by diseases and insects.

Bayberry can be grafted with the following trees:

1. Water chestnut seeds, produced in Lanxi Majian, Yuyao, Cixi, Zhejiang Province. The tree is modest, the fruit weighs 10 grams, the left is missing the right, and the purple-black is purple-black. The taste is sweet and slightly sour, and the kernel is small and juicy.

2. Late rice bayberry, produced in Zhoushan, Zhejiang Province. The tree is strong, the average weight of the fruit is about 11.2 grams, it is round, and the color is purple and black shiny.

3. Dongkui, Dongao Village, Jiangkou Township, Huangyan District. The tree is vigorous, with a tall crown, with an average fruit of 24 grams and a maximum of 42 grams, purple-red or red, with a thick flesh column and a moderate sweetness and acidity.

4. Ding Ao plum, produced in Ding Ao Village, Chashan, Wenzhou City, the tree is strong, the branches are relatively sparse, the fruit is large, the average weight is 15 to 18 grams, purple red, the flesh is thick, the quality is soft, the juice is sweet and sweet.

5 large leaves and fine pedicles, produced in Dongting East and West Mountain, Jiangsu, the tree is strong, the leaves are large and thick, the fruit is large, weighs 13 grams, the color is purple red or purple black, the meat is fine and juicy, sweet and sour, and the quality is good.

Bayberry grafting can choose trees of the same family as the royal block, that is, trees of the poplar family can be selected.

The suitable time for bayberry grafting is before spring budding, generally from early February to late March, the climate during this time is more suitable, and after grafting, it can germinate and grow immediately.

The time of grafting can not be later than before and after the Qingming Festival, if the grafting is too late, the fluidity of bayberry sap or dress will be relatively large, and too much liquid will flow out during grafting, which will affect the survival rate of grafting.

Methods of grafting bayberry trees:

1. Select branches: cut a section of weak and robust branches on the high-yield bayberry trees that have entered the full fruiting period, preferably 1 2-year-old branches in the middle and upper part of the crown and growing in the periphery, and prune the branches into 6 7 cm scions.

2. Prepare rootstocks: rootstocks are generally selected from wild-sown bayberry seedlings or self-sown seedlings, which are generally sown with seeds and have been cultivated for 2 to 3 years of high-quality bayberry seedlings. This is more conducive to grafting into shirts and yards.

3. Reasonable grafting: cut the bottom of the scion into a wedge shape during grafting, and then tightly fit it with the rootstock, and then wrap and tie it together with plastic film. This is to reduce the evaporation of water from the scion and improve the survival rate.
