Introduction of common propagation methods of Yu plum

Yu Li likes a sunny, warm and humid environment. The flowering period is from March to April. The flowers and leaves bloom together, and they are very beautiful when they bloom. Yu plum has strong adaptability and can also adapt to slightly acidic soil. Artificial propagation of Yu plum can be done by means of plant division, sowing, cuttage, striping, grafting and so on.

I. split-plant propagation

Yu plum has strong sprouting and many root tillers, so it is appropriate to separate the sprouting seedlings at the root of the mother plant with a sharp knife before sprouting in spring, each plant can be divided into 3 to 5 plants, and then transplant. Usually flowers can be seen two years after survival.

2. Cutting propagation

Can be cut from February to March, select the lower part of the annual sturdy sprouting, cut and grow 10 cm to 15 cm with two or three buds as cuttings, and insert them into the soil. After the cuttings were watered thoroughly, the high air humidity was maintained and it could take root in about 1 month. Because the root of Yu plum is easy to produce adventitious buds, the effect of propagation by root insertion is also better.

3. Sowing and reproduction

It can be sown in spring and autumn, from late February to mid-March in spring and from September to mid-October in autumn, but autumn sowing is better. The seeds can be collected in the first ten days of June, washed and dried after heap, sown in autumn, or stored in low temperature sand, and then sowed in the open field in the following spring. The sowing rate is about 10 grams per square meter, with a sowing depth of 4 to 5 centimeters, covering a fine layer of soil after sowing, and covering the surface with straw or other objects to maintain soil moisture and make its seedlings emerge neatly.

IV. Grafting propagation

The grafting mainly adopts T-shaped bud grafting, and the robust 2012 plum varieties are selected as scions, and the rootstocks can use robust apricot, plum, hairy peach, hairy cherry and so on. When taking the bud, first cut it in the upper 1 cm of the bud with a sharp knife, cut through the xylem to 1 cm under the bud, and wrap the bud with a wet towel. Carve a "T" shape on the rootstock, insert the bud into the rootstock, align the upper end with the cambium, and then tie it with plastic tape. The grafting affinity of Yu plum is strong, and it is easy to survive. After survival, untie the binding and cut the rootstock. Yu plum is also often used as a rootstock for peaches, apricots and plums.

Propagation methods of Yu Prunus

Ramet Propagation of Yu Plum

Because the sprouting ability of Yu plum is strong and there are many root tillers, ramet propagation is a common reproduction method of Yu plum. The specific method is to cut off the sprouting seedlings from the roots of the mother plant in spring and then transplant it. Each mother plant can be divided into three to five plants. Ramets usually blossom two years after they survive.

Cuttage propagation of Yu plum because the root of Yu plum is easy to produce adventitious buds, so the effect of root cuttage propagation is better. The specific method is to carry out cutting in early spring, select the relatively sturdy lower part of the annual sprouting, cut and grow 10 cm to 15 cm with buds as cuttings, and insert more than half of the soil. Then the cuttings are watered regularly to maintain air humidity, which can take root in about a month, and then sprout and grow.

Sowing and Propagation of Yu Plum

Sowing and reproduction is the most common method of reproduction. The specific method is to sow seeds in the spring and autumn season, but it is better to sow in autumn. For autumn sowing, the seeds should be collected at the beginning of summer, then washed and dried naturally in a cool place until the autumn sowing period, and for spring sowing, the seeds are also collected at the beginning of summer, and then the seeds are stored in low temperature sand. Sow next spring. Attention should be paid to the distance between plants and seedlings and the planting depth when sowing.

The grafting propagation of Yu plum has strong grafting affinity and is easy to survive, but the method of grafting propagation is complex and requires professional knowledge, so it is not commonly used. The specific method is to adopt T-shaped bud grafting, select strong plum varieties as scions, and select branches such as apricot plum as rootstocks. When taking the bud, cut it from the upper 1 cm of the bud, cut through the xylem to 1 cm below the bud, remove the bud and wrap it in a wet towel and set aside. At this point, carve a "T" shape on the rootstock, insert the bud into the rootstock, align the upper end with the cambium, and then tie it with plastic tape. After survival, untie the bandage and cut the anvil. Culture and nursing methods of Yu plum

[plum habits] sunny, drought-tolerant, moisture-tolerant, strong growth adaptability, many root tillers are clustered. [plum cultivation and management] (1) it is commonly used for branch propagation, cutting and sowing. (2) potted with a diameter of 15 ~ 20 cm, garden soil for potted soil, and planted with base fertilizer. (3) potted flowers should be placed in a sunny place to facilitate flower bud differentiation, and can be placed indoors or in the shade during flowering to prolong the flowering period. (4) the basin soil was watered as soon as it was dry, and the dilute nitrogen and phosphorus fertilizer solution was applied once a month from March to September. (5) ramets when falling leaves and changing pots after autumn.
