If the cuttings are not easy to survive.

You can try the strip or the high-altitude strip, it's very simple. It is effective for plants that are not easy to survive by cuttings.

Here's the references that you can look at.

When cutting cherry blossoms, you should use a small stick slightly thicker than the cuttings, insert the cuttings vertically, with a depth of 5-6 cm and a spacing of about 10 cm, and then insert the cuttings, and then press them firmly with your hands. After insertion, spray the water thoroughly with a thin-eye watering can to make the cuttings tightly bound to the soil.

This cherry tree is planted in my yard, the age of the tree is about 40 years, the specific variety is unknown, if the cherry blossoms are not suitable for cuttings, if the cuttings are not easy to survive, you can try the strip or high-altitude strip, it is very simple. It is not easy for cuttings.

Cherry blossom cuttings propagation method.

1. Selection of cuttings.

Select a young and robust mother tree, cut the annual thick branches in the middle and upper periphery of the canopy, keep the top tip, cut into 30-40 cm long cuttings, cut into oblique cuts in the lower part, and cut the cuttings on the same day to be planted on the same day to prevent the cuttings from losing water, bruising the incision and tissue necrosis. It is important to note that weak cuttings will reduce the survival rate, and short cuttings will delay the seedling stage.

2. Do a good job of cutting bed.

The cuttings bed chooses the leeward and sunny drainage terrain, as a bed furrow with a width of 1 meter and a height of 30 cm, the bottom layer of the bed furrow is paved with 15 cm thick sandy loam soil with a certain fertility, and the upper layer is covered with 10 cm of yellow heart sandy loam (prepared with 2 parts of yellow sand with 8 wounds of yellow heart loam), and sterilized treatment.

3. Master the cutting time.

Cherry blossoms are deciduous tree species, annual large-branched cuttings, which should be done before the buds have germinated. When the soil temperature reaches 16 or more, the cuttings begin to take root.

4. Pay attention to the method of cuttings.

Use a small stick slightly thicker than the cuttings, insert the cuttings vertically, 5-6 cm deep, about 10 cm apart, then insert the cuttings, and then press them firmly with your hands. After insertion, spray the water thoroughly with a thin-eye watering can to make the cuttings tightly bound to the soil.

5. Do a good job of post-plugging management.

Moisturizes and retains heat to promote healing and rooting. In the first half of March, the temperature is generally unstable, high and low, if the temperature drops greatly, emergency measures can be taken to cover the plastic film, such as the maximum daily temperature reaches more than 15, spray once at noon, later with the stable increase of temperature, spray 3-4 times a day, it is advisable to not whiten the topsoil. In order to improve the soil condition and allow it to form healing tissue as soon as possible, 15-20 days after cutting, extra-root topdressing was carried out with potassium dihydrogen phosphate at a concentration of 2%.

It takes about a month or so for it to heal and take root.

Build a shade shelter. After insertion, erect scaffolding, prepare for shading, and the height of the scaffolding should be slightly higher than that of people, so as to facilitate operation. It is conducive to ventilation and creates a microclimate in the slotted bed.

When the maximum temperature of the day is above 16, cover the curtain or shade with a blackout net, the shading rate is 50-70%, and it is best to cover it day and night.

Remove the tillers and wipe the buds. The thick cuttings of the cherry blossoms are rich in nutrients on their own, and the sun is abundant and the temperature is too high. Buds and leaves begin to germinate in large numbers when they are not rooted. At this time, except for the retention of the apical bud, the rest are erased; So as not to deplete too much nutrients.

Timely topdressing to promote the growth of root groups. In order to meet the growth requirements of cuttings, thin fertilizer should be applied once in time one week after rooting, and then every 15 days (the cool department will stop applying). In this way, after three to four times of fertilization, the roots of the seedlings are up to the top, the growth is vigorous, and the nutrients can be absorbed in advance, the growth height of the year can reach more than 1 meter, and the next year can be transplanted in early spring to cultivate large seedlings.

Pay attention to disease prevention and insect treatment. Cherry blossom seedlings are susceptible to pests and diseases, and their leaves are susceptible to leaf spot. Carbendazim can be sprayed once every half a month with 800 times the liquid, and the tender shoots of the apical buds are easy to grow tender shoots borer and aphids, once the hatching larvae are found, they should be sprayed in time to prevent and control. so as not to damage the seedlings.

Cuttings may be alive, I took the branches that sprouted quickly in early March, and inserted them directly into the soil, and now they have grown leaves.

Rooting powder is generally not required before planting, and cuttings are generally done in the spring, when the cherry blossoms germinate.

Cherry blossoms are generally propagated without cuttings, and the survival rate is very low. Even if there are many steps to be taken to cut them, there are seasonal restrictions, and in general, cuttings should not be taken.
