The method of Cuttage Propagation of Pearl Plum

Pearl plum is native to northern Asia and is distributed in Hebei, Henan, Shaanxi, Gansu, Shandong, Shanxi and Inner Mongolia. Sex likes sunshine and has strong shade tolerance, cold tolerance, moisture tolerance and drought tolerance. If the soil is not strict, it can grow normally in ordinary soil, but it grows stronger in moist and fertile soil. Common cultivation of garden green space and residential courtyard in the north of China. Fast growth, strong sprouting ability and resistance to pruning. Can be used to remove the old branch of the method of alternating between the new and the old, constantly updated and rejuvenated. In the growing season, if not collecting seeds, it is appropriate to cut off the remaining flower branches at any time after flowering, in order to maintain the perfect plant posture.

The method of Cuttage Propagation of Pearl Plum

1. Seed collection and treatment seed collection from September to October every year, put the capsule in a ventilated and cool room, dry in the shade, gently rub, remove the seed shell and impurities, and store it in a paper bag.

two。 Land preparation and bed making choose the land with flat terrain and good drainage as the seedling land, and the greenhouse can also be used to raise seedlings. The soil of the seedling land should be loose and have good fertility. Low-bed seedling, bed width 1.0-1.2 meters, length 5-10 meters, deep turn, remove debris and weeds, use carbofuran or phoxim to kill insects, carbendazim soil disinfection. Pour enough water before sowing.

3. Sowing method Pearl plum seeds are small, sowing using sitting water method. When sowing, the soil should be moist but not sticky. Rake the ground flat, fine, sow the seed mixture, cover the thin soil after sowing, preferably forest humus, and then sprinkle water with a spray pot to closely combine the seeds with the soil.

4. After sowing at seedling stage, the surface was covered with sunshade net, sprinkled with water once or twice a day, seedlings were raised in open field for 3 or 5 days, and seedlings were raised in greenhouse for 2 or 4 days. The soil must be kept moist at the seedling stage. After the seedlings came out, the shading time was gradually reduced and the sunshine time was increased. The greenhouse seedlings were removed from the sunshade net in about 20 days, and the open-field seedlings were removed from the sunshade net in about 30 days. After sowing and raising seedlings in the open field, the height of the seedlings is 515 cm after 1 year, and it can grow to about 50 cm at 2 years old. 2-year-old transplanting and planting, the plant row spacing is 40 cm × 60 cm, 4 ~ 5 years out of the nursery, raising seedlings in the greenhouse, the growth height can reach 30 ~ 50 cm in the same year, transplant in the open field in the second year, and leave the nursery for 3 ~ 4 years.

Economic value: it can be cultivated for ornamental use; stem bark, branches and ears are used as medicine, which can promote blood circulation and disperse blood stasis, reduce swelling and relieve pain, and mainly treat fracture, fall injury and rheumatoid arthritis.

How to propagate triangulated plum and the method of cutting propagation of triangulated plum

Triangulated plum how to reproduce, triangular plum is very easy to reproduce flowering plants, after warm spring can be cut, and the success rate of reproduction is particularly high, let's take a look at how to cuttage is good success, how to promote triangular plum blossom faster.

The method of cutting propagation of Prunus mume 1. Selection of cutting time

The best choice of cutting cultivation is in spring, followed by summer and autumn. After spring is warm, cuttings can be carried out.

Indoor cutting in winter is also feasible, of course, as long as there is indoor heating and maintain a temperature of about 20-25 degrees.

2. Selection of cutting pot soil.

Generally, it is cultivated in a well-drained basin, and the soil uses commonly used sandy soil, which can be mixed with river sand, rotten leaf soil and garden soil, or mixed with peat soil and perlite at 1:1.

The potted soil needs to be disinfected and exposed to the sun before cutting and growing branches, but the sun is not strong enough in winter, so you can irrigate it with carbendazim and water.

After disinfection, add cork annual branches, too old branches are difficult to cuttage root, with cork branches or it is easy to cultivate successfully.

3. Points for attention in cultivation

Cuttings must be cut flat, tools used to cut branches must be sharp, pre-selected for disinfection, and triangulated plums of different plants must be disinfected before cutting to avoid cross-infection.

Keep the environment warm, moist and shaded, keep the basin soil moist and avoid the soil from being too dry, so it is easy to ensure the success rate of cutting.

How to raise triangular plum to blossom easily? 1. Appropriate drought

Proper drying can make it grow more flowers, but not too dry, which will harden the soil and make the plants breathless (breathless).

2. Regular fertilization

Triangular plum is of course like fertilizer, thin fertilizer is the key to frequent application, fertilization too frequently will lead to plant branches and leaves grow too luxuriantly.

In addition, pay attention to do not apply fertilizer indiscriminately, if you apply thick fertilizer, it is very easy to kill triangulated plum, do not only use high-phosphorus fertilizer, the best is organic fertilizer or slow-release fertilizer, their effect is the best.

4. Proper pruning

Triangular plum pruning is pruning after flowering and winter pruning. The purpose of pruning after flowering is to adjust the plant type and promote the next batch of flowers to open early, so the residual flowers should be cut as early as possible, and the whole plant should be trimmed so that the next time it blossoms at the same time.

The triangular plum cultivated on the balcony will generally cut off all the new branches from the old branches of the previous year.

5. Why doesn't triangular plum blossom?

If there is plenty of sunshine, it is usually caused by too much watering, properly reduce watering, let the basin soil dry for a while and then water it, keep the environment relatively dry, but not too wet, it likes to be cool.

The propagation method of Prunus mume, cutting propagation of Prunus mume

Cuttage propagation of Prunus mume

A. Pre-cutting preparation

The first thing to prepare is naturally the soil matrix. You can use sandy soil and add some perlite and peat.

And then the flowerpot. Triangular plum does not have high requirements for flowerpots, just a simple plastic pot.

Finally, prepare the branches to be cut. Cut off strong branches that have been lignified or semi-lignified in the current year.

B. Triangulated plum cuttage

Cutting propagation method

Insert the cuttings into the mud at a depth of about 7-8 cm, exposing branches with leaves.

After inserting, pour through the water, cover the whole surface of the flowerpot with a layer of plastic film to keep the humidity, and put it in a place where scattered light can shine.

C. Maintenance and management after cutting

The most important thing in the maintenance of triangular plum is to keep it moist and breathable.

If the moisturizing is not enough, the leaves will wilt and scorch. If the flower mud is dry and the leaves will wilt, spray some water.

Open the cling film every evening for proper ventilation. It is too muggy inside, the branches will be moldy, and the plant will hardly survive.

High pressure Propagation of Prunus mume

High-pressure reproduction, that is, high-altitude striping reproduction.

A, the advantages of high pressure propagation

First, the survival rate is high. The branches that come out of the root system under high pressure can basically survive as long as the root system is not injured and cut off and transplanted.

Second, there is basically no need to slow down seedlings.

Third, it is easy to form. After the branches are under high pressure, they are transplanted into a new pot. with a little pruning, they will immediately grow into a healthy and beautiful bonsai flower.

B. steps of high pressure propagation method

First of all, the branches that need high pressure are placed two inches above the bifurcation of the female parent, and the width of the ring is about 3 mm. And clean the outer skin.

High pressure propagation of Prunus mume

Wrap the branches in rich, moist soil and fasten them with plastic bags at both ends.

After the plastic bag is wrapped, it will not lose water and dry. If the soil is dry, water can be injected with a syringe.

More than a month later, you can see a lot of roots growing through the plastic bag, and then you can cut off and transplant.

Propagation method of Prunus mume

The main results are as follows: 1. The selection of cuttings: the branches of Prunus mume as thick as arms and as thin as incense can be used for cutting; the roots of coarse branches are late and take shape quickly; annual lignified green branches are easy to produce new roots and have a high survival rate. Generally choose 1-2-year-old outer layer sunny branches with compact and sturdy structure, (not too twigs, immature branches, only long branches, shade branches.) Cut into 3-4 segments (about 8-10cm) with a sharp knife, the lower oblique cutting surface is 5-10 mm below the node, remove the lower leaves and retain the upper two-and-a-half (full) leaves as cuttings.

2. The cutting medium should be vermiculite, perlite + vermiculite, pure sand, sandy loam (plain soil). Put it in a basin and soak it in boiling water for several times before use and use after cooling. It can also be inserted with water.

3. Master seasonal cuttage. Hangzhou cuttings are best before mildew in late May to early June. (there are differences in different places, if there is an article that Hainan is the best in March of the following year in October, both in spring, summer and autumn in Fuzhou.) at this time, the temperature is suitable (20-30 degrees), high humidity and convenient management. First, use a small stick thicker than the cuttings on the substrate, and punch holes obliquely on the substrate. Insert cuttings with a depth of about 4-6cm, and water them in a slightly shady place for maintenance.

4. Maintenance: the light should be suitable: sparse light should be seen in 15 days, (it should not be too shady, sunshade is about 50%) and then gradually strengthen the light, grow new roots in 20-30 days, and shine all day for about 25 days; only by fully accepting the sun can we make the new roots strong. Moisturizing: if the weather is dry within 20 days, keep the fresh-keeping film moisturizing and keep the ventilation hole. Open the ventilation in the evening, spray water and cover it again.
