Grafting Propagation methods and key points of potted Plum Blossom

How to cultivate potted plum blossoms? How to graft potted plum blossoms? How to manage after grafting? Plum blossom grafting is a commonly used breeding method in gardens. Mountain apricot can be used as rootstock and holy rose plum as intermediate stock to graft plum blossoms. The following introduces the main technical points.

1. time

It is suitable to choose the temperature rising in the middle of March, the plant sap flowing, and the temperature of 8-15 ℃ for grafting.

1.1 scion selection

The selection of ① anvil. The 3-year-old mountain apricot with a ground diameter of about 5cm, strong growth and no diseases and insect pests was selected as the rootstock.

The seed strip of 1-year-old Saint Rose Plum was selected as the scion of ② interstock.

③ plum blossom scion selected one-year-old plum seed strips with strong cold resistance.

two。 Grafting method

2.1 adopt split connection method

① cut the apricot rootstock in the plane off the ground 20cm and split the smooth surface in the middle to form a long interface of 3.5cm.

② cut the one-year-old St. Rose Plum seed strips into 15cm segments as interstock scions, cut one end into a double-sided Maltese-shaped slope, and inserted them into the anvil interface to align the cambium of the interrootstock scions with the rootstock cambium and fasten them with plastic strips to make the interstock scions.

③ then split the upper end of the interstock scion to form a long interface of 3.5cm.

Finally, ④ cut the 1-year-old plum seed strips into 10cm segments as scions, cut the lower end into a double-sided Mal-shaped slope, inserted into the interface of the interstock, aligned the cambium of the two, and finally wrapped them tightly with plastic strips.

3. Management after grafting

Wiping buds and coring in time after grafting survived, promoting bifurcation, increasing growth, promoting flower bud differentiation, forming flower buds in the same year, blooming in large quantities the following year; applying basal fertilizer or foliar spraying fertilizer, mainly topdressing phosphorus and potassium fertilizer, so that plants concentrate fertility, promote nutrition absorption, promote maturity, enhance overwintering ability, pest control, conventional production management, and so on.

Using mountain apricot as rootstock has the advantages of developed root system, fast growth, strong growth, strong resistance and resistance to diseases and insect pests, and using holy rose plum seed strips as interstock has the advantages of strong growth, fast growth, strong resistance, frost resistance and many flowers; the use of plum seed strips as scions has the characteristics of strong cold resistance, early flowering, beautiful flower pattern and high ornamental value. The breeding efficiency was improved by an one-time "double" connection between rootstock, interstock and scion in a seasonal period.

These are all about the grafting of plum blossoms today. If you also plant plum blossoms at home, you must master the knowledge and take good care of it.

How to raise the plum blossom? Culture methods and matters needing attention of preserved plum

[FAQ] how to raise wax plum blossoms? Culture methods and matters needing attention of preserved plum

[expert answers]

Prunus mume planting

(1) planting on the ground. The planting of dried plum should be in the leeward and sunny place, and the transplanting time is mostly in winter and spring, and the root of the seedling must carry a mass of soil. Before planting, apply enough manure, barnyard manure or rotten bean cake as base fertilizer in the planting hole. After applying the base fertilizer, cover the fertilizer with a thin layer of soil, and then put the seedlings to fill the soil. After planting, it should be watered and pruned properly.

(2) potted plants. When potted Lamei is cultivated, the sandy loam which is loose and fertile and rich in humus should be selected. After putting on the basin, pour water in time, put it under the shade shed and slow the seedling for about a month, and then keep it in the courtyard or on the balcony where there is plenty of sunshine for maintenance.

Key points of maintenance:

1. Fertilization

The management of dried plum can be more extensive. In general, liquid fertilizer is applied every 20 days from June to September every year (bone meal and cake fertilizer can be used to soak in water and apply after full maturity), which can ensure the good development of branches, leaves and flower buds.

Potted wax plum, usually should often be fertilized, in order to promote its formation of a large number of buds, otherwise flowering is rare. Generally, mature cake fertilizer and water are applied every 7 days between May and June every year, and the ratio of fertilizer to water can be matched by 3:10. The flower bud formation period of Prunus mume is from July to August, and fertilization can be done every 15-20 days, and the concentration of fertilizer and water should be dilute, and the ratio of fertilizer and water should be 1:5. This is conducive to flower bud differentiation. The fertilizer must be fully rotten, or the roots will rot. Apply dry cake fertilizer again after autumn to meet the nutrient needs of flowering. After the beginning of winter, it is necessary to make the pot soil dry and no longer apply fertilizer, otherwise the florescence will be shortened.

2. Watering

The ground-planted Lamei was watered once before the early winter, fertilized once after the flowers faded, and watered once, usually not watered, but only properly watered when the weather was too dry.

Potted wax plum watering should grasp the principle of dry re-watering, not more watering, pot soil should not be too wet; but also should not be too dry, too dry will lead to irregular blossoms.

3. Temperature and light

Potted preserved plum was moved indoors in December. If the room temperature is high, it can blossom before New Year's Day, but if the room temperature is low, the florescence can be delayed until around the Spring Festival. After flowering, it should be moved to a shady place to prevent premature drawing of new shoots and leaves, affecting flower bud differentiation and disadvantageous to flowering in the coming year.

4. Shaping and pruning

Wax plum germination is strong, after flowering should be pruned in time, generally cut off more than 20 cm part of the flower branch, and cut the elongated branch of the previous year, leaving 1-2 pairs of buds. In this way, nutrients can be concentrated on new shoots and create favorable conditions for outstanding and large flowers the following year.

5. Reproduction

Prunus mume can be propagated by sowing, striping, grafting, split and other methods. The sowing method is not generally adopted because it is not easy to maintain the original excellent characteristics of flowers. Grafting is widely used, and there are two methods of grafting: cutting and leaning, and cutting is the most commonly used.

The cutting time is about the middle of March, and it is best to do it when the leaf bud has just germinated to the size of the rice grain. It is not easy to survive if the leaf bud is too large or leaves have been sent out. The seedlings of Gouya plum are usually used as rootstocks and precious varieties such as Suxin or Pankou plum as scions. The scion should select one-year-old sturdy and long branches and cut off their tips one month in advance, so that nutrients can be concentrated on the buds in the middle of the branches. The scion is 7-8 cm long, leaving 1-2 pairs of buds. When cutting the scion, it should not be cut too deep, and the xylem shall prevail. The rootstock is cut from 5-6 cm off the ground, cut down from 1 beat 3 of the diameter of the rootstock, split 4-5 cm, and insert the scion into the incision of the rootstock, aiming at the cambium. After being connected, bind it firmly with soft hemp skin, and then seal the rootstock and scion with loose soil until the top of the scion is covered. Keep the soil moist after that. One month later, loosen the seal to check whether it has survived, and if it has survived, wipe out other new buds on the rootstock to promote bud growth. Then the loose soil is still covered to prevent the fresh buds from being killed by the wind and sun. After another month, the soil was gradually removed, and the buds were gradually exposed to sunlight. The preserved plum propagated by this method grows exuberantly and can grow to about 50 cm in that year.

6. Disease and pest control

(1) disease. In the process of conventional cultivation, high temperature and humidity in summer are prone to bacterial diseases such as brown spot and leaf spot. The control can be sprayed with 500 times carbendazim solution. In addition, it is necessary to strengthen daily management and do a good job of prevention.

(2) insect words. There are mites, leaf-eaters and stem insects that invade Chinese plum.

Control methods: integrated control methods can be used for trunk borer pests. The resistance of hatched larvae is poor at the beginning of July. 1000-fold solution of 90% trichlorfon can be injected into the borer holes in the trunk to kill larvae. If the density of the insect population is low, plug the wormhole with a poison label. During the peak period of adult Eclosion in September, the adults were trapped and killed by light.

[editor's comments] Lamei is one of China's traditional valuable ornamental flowers and trees, originally from central China, is now cultivated everywhere, blossoms at the end of winter, and now many people will make bonsai to decorate their homes. I believe that many friends would like to know how to raise plum blossoms. The above are the farming methods and points for attention of the first agricultural scripture editor for you. I hope it will be helpful to you.

The planting method of plum blossom

Flower Bonsai net Flower maintenance column: the planting method of plum blossom will introduce you to the cultivation method of plum blossom, how good plum blossom is, and the prevention and control of diseases and insect pests of plum blossom.

Plum blossom belongs to Rosaceae trees and flowers.

[ornamental value of plum blossoms] the first leaves of the flowers are open, with fragrance, there are more than a hundred varieties, and the colors are white, pink, red and purple, which are the traditional famous flowers in China. Flowering 1 ~ 2 months, Ye Xiuzhi beautiful, simple and elegant, often used as a potted pile landscape.

[plum blossom habits] (1) good sunshine, if kept in the shade for a long time, there will be few flowers. (2) suitable for warm and humid, frost injury below-18 ℃. Sensitive to air pollution and poor growth in urban environment. (3) Sandy loam with good drainage and like dampness and fear of waterlogging. [main points of plum blossom cultivation] (1) improved varieties are used for propagation to graft Mao peach rootstocks. (2) 6 ~ 7 parts of garden soil for basin soil were mixed with 3 ~ 4 parts of carbon ash. (3) the basin soil should be dry-poured and wet-stopped after germination. Watering of flower buds should be postponed in early summer. The soil should be kept moist and not too dry in summer and autumn. If the leaves are not too dry, they do not need to be watered. In the middle of winter and early spring, it should be slightly wetter than after falling leaves. In short, the pot soil should not be too wet, otherwise it is easy to rot the roots. (4) No fertilizer should be applied after defoliation, once fertilizer should be applied after flowering, and one proper topdressing should be applied from late August to September. Fertilizer can be used with rotten oil, dry water or human feces and urine. (5) pruning in winter or after flowering, pruning and pruning young trees to keep their length properly to promote the emergence of more branches. The old tree should be re-pruned properly, and the length and direction of the branches should be considered to be graceful (see Q & A 69-70 for details). (6) potted flowers should be placed in the sunny place in spring, summer and autumn to facilitate ventilation and light to reduce diseases and insect pests.
