Grafting time and method of persimmon what kind of tree can persimmon be grafted

Everyone likes to eat persimmon in life, right? Persimmon is a kind of sweet and juicy fruit, which is very common in our life, and this kind of fruit has high nutritional value and is loved by many people. The propagation method of this kind of fruit is usually based on grafting, so let's follow the editor to learn more about it.

Grafting time and method of persimmon

1. Grafting period

Because of the vast land in China and the great difference in climate between the north and the south, the grafting period will be different sooner or later. Generally speaking, from March to April in spring, when the sap of the rootstock flows to the leaf expansion, it should not be grafted when the rootstock has not yet germinated and the scion has already sprouted; from mid-August to late September in autumn, when the rootstock is still off the skin and the branch epidermis of the scion is brown and red, when the buds are full and full.

2. Grafting method

Grafting methods are more or less the same in different places, single bud grafting is the fastest and most economical scion in nursery grafting, cutting, abdominal grafting and split grafting are OK, grafting personnel can use the most familiar and good method, and the survival rate is the highest, so there is no need to insist on consistency. If the rootstock is thick enough to peel off the skin, the subcutaneous grafting method is the best.

You can also take a single bud mosaic, cut the bud into a shield shape at 1 cm above the bud, and cut the slope with an angle of 60 °at 1 cm from the bud. The rootstock is 10 cm from the ground, cut off a bud that is the same as the bud, immediately insert the bud, wrap it with agricultural film strips, and expose the bud. Those grafted in spring are cut at 20 cm above the interface to promote germination, the residual pile can replace the pillar to prevent it from being broken by the wind, and those grafted in autumn do not cut the rootstock to avoid germination and freeze to death.

What kind of trees can persimmon trees be grafted

Black jujube, the scientific name Jun Qianzi, also known as wild persimmon. Widely distributed in northern China, mainly divided into seedless and seedless two kinds, the main varieties are big nuclear black jujube, milk jujube and grape black jujube and so on. Persimmon trees can graft black dates. Generally, it begins to bear fruit 3-4 years after grafting, and reaches the full fruit period 15 years later, and the economic life is as long as 100 years, so it is said that "one year planting, one hundred years income".

Persimmon trees are not strict in the selection of soil quality, regardless of mountains, hills, plains, beaches, fertile land, barren land, clay, sandy soil can get considerable yield. Therefore, the development of persimmon production plays an important role in making full use of land, increasing ground coverage, improving climate and improving people's living environment. Persimmon crown opening, bright leaves clean green trees thick shadow, summer can be shaded and cool; into autumn green leaves Dan fruit, bright and pleasing to the eye, late autumn red leaves can be compared with maple leaves, is also an excellent ornamental tree.

Grafting methods of Persimmon trees

1. Branch grafting: there are two methods of branch grafting: split grafting and skin grafting.

The main results are as follows: (1) before the splicing sap is not flowing, the tree can be split, cut off the tree, cut vertically and longitudinally with the cross section, cut both sides of the scion into a wedge, and insert the cuttings with at least one side of the cambium opposite to each other. If the wood is thick, another scion can be inserted at the other end of the incision to align the cambium on one side.

(2) after the bark grafting sap flows (off the bark), the bark graft is often used. The scion is cut into a horseshoe shape, the cutting surface is more than 2 cm long, and the opposite side is cut into a small horseshoe shape, 0.3-0.5 cm long, so that the lower end is wedge-shaped and easy to insert. Cut off the rosewood at the grafting site, cut a vertical knife edge of 1-2 cm on the smooth side, and then insert the cut scion to show a little white. Then tie it tightly and tightly with plastic strips.

2. Budding: budding is carried out from June to July, mostly with T-shaped budding and square budding. Persimmon branches contain tannin, the wound is easy to oxidize and discolor, affecting survival, so it is required to complete the grafting as quickly as possible.

What are the points for attention of grafted persimmon trees

1. The fresh activity of scion should be high.

If the scion loses water during long-distance transportation, or if the scion is stored improperly, the vigor decreases, and the cambium cells cannot restore their ability to divide, they will not survive, or the survival rate is very low. So take the full and robust scion and scion sand storage period to control the sand humidity and maintain the vitality of the scion.

2. the growth potential of rootstocks should be strong.

In weak rootstocks, the division energy of cambium cells is low, and then it is not easy to survive, even if they survive, the seedlings do not grow vigorously. Therefore, it is necessary to do a good job in the management of rootstock before grafting to ensure that rootstock seedlings thrive.

3. The cutting surface of scion and rootstock is flat and cambium is aligned.

The cutting surface of scion and rootstock is smooth, which reduces the seam and shortens the distance between scion and rootstock, so that the callus can fill the seam quickly and connect the channel between panicle rootstock as soon as possible.

4. Interface moisturizing

The joint buds are tightly wrapped with plastic film to make the humidity close to saturation, which is beneficial to the scion without losing water and keeping it alive.

The grafting method of persimmon is not difficult, and the survival rate of this breeding method is also very high. The most important thing to pay attention to in the process of grafting is to ensure the freshness of the scion, the flatness of the grafting surface and the growth state of the rootstock and so on.
