How to choose a substrate for cuttings? How to choose a substrate for cuttings

The cuttings used in general types require loose aeration, no uncooked organic matter, and no salts. Commonly used are river sand, vermiculite, perlite, plain sandy soil, peaty soil, decaying moss, chaff ash and sawdust.

No matter what kind of substrate should be clean, uniform particles, medium size, the substrate in the slotting bed should generally not be spread too thick, otherwise it is not conducive to the temperature of the substrate and affect rooting.

After the scion of the grafted plant is formed, it is sometimes necessary to take it from the rootstock and cut the roots, and you can use a pot slightly larger than the plant to cut a single plant.

Flower cuttings for seedlings should choose a substrate that adapts to plant physiology. For those flowers and trees that are not suitable for cuttings in the soil, the following substrate cuttings should be selected:

1. River sand. The river sand is preferably coarse stone without organic matter, which has the characteristics of good aeration, easy heat absorption, fast heating, and conducive to rooting. However, it has poor water retention and should be replenished in time.

Cuttings are native to tropical desert plants, such as cacti in succulent plants, etc., in addition, it is also a good material for leaf cuttings flowers Chitose orchid, large rock paulownia, river sand and peat with strong water retention power mixed with the same amount of materials, has a better effect on most flower cuttings.

2. Water. Plants that take root by cuttings in water, such as roses, pomegranates, etc. The water used for cuttings should be changed frequently to keep the oxygen in the water sufficient, and the dark bottle of the container is better to facilitate rooting.

3. Vermiculite and perlite.

Vermiculite, perlite is an ideal substrate for cuttings of various flower seedlings.

4. Peat and humus, etc.

Peat, humus has strong water retention, and if mixed with river sand, it is suitable for cuttings of many temperature flowers. In addition, humus soil can also be used as a substrate for cuttings.

Can nutrient soil be used for cuttings? What substrate is used to cut the highest survival rate.

Hello, I'm happy to answer your question, in fact, the best and most affordable and simple substrate for cuttings is to use sand or silt, and then go to the pharmacy to buy a bottle of potassium permanganate, 10% dilution and disinfection, in the cuttings can be.

1.Take a single leaf or a small section of branches and leaves, if possible, you can use rooting powder, soak the branches in ABT6 10 (soluble in water, do not 1 5, 1 5 is soluble in alcohol) rooting powder content of 500 200 mg kg solution for 30 seconds before cuttings.

2.With nutrient soil, the standard mix is peat, perlite and river sand according to 3:1:

The ratio of 1 is mixed and formulated into a substrate, if there is no peat soil, you can use garden soil, no perlite can use sawdust, or you can do without! Perlite is still more expensive! There is no river sand, you can use sand!

The principle of the picture is breathable, moisturizing and fertilizer! The proportions are roughly fine!

3.Cuttings and placed on the north side! Moisturize and you're done! Just touch the soil with your hands every day to moisten it! When dry, you need to water.

4.Temperature! Just take cuttings in a few days! It will be alive in about 2 weeks!

5.It can be potted after rooting! According to the configuration of the culture soil, add some fertilizer! You can use compound fertilizer and twist it into powder! (About 15 to 20 capsules!) ）

In the future management, we must insist on preferring dry and wet by mistake, and pouring that is, pouring thoroughly! That is, the soil should not be too wet, and the watering should be thoroughly watered once! Just leave water from the bottom of the pot!

Experts will tell you how to mix the seedling substrate.

1. River sand: coarse particles, good aeration performance, no impurities, quite pure, but poor water retention and thermal insulation performance. It is mostly used for shrub-like foliage flowers that are easy to root and have fast roots.

2. Vermiculite: It is a pure mineral, quite clean, has good aeration and water permeability, and can maintain a relatively constant temperature, which can promote the early rooting of cuttings. However, the water retention performance is poor, and it is best to mix it with brown peat.

It is mainly used to cut evergreen coniferous foliage flowers such as dragon cypress, cypress, creeping cypress, black pine, and araucaria.

3. Water and sediment isolation.

4. Peat.

It is loose and aerated, relatively clean, with strong water retention and heat preservation performance, and shows a weak acidic reaction. However, after lack of water, it often agglomerates and hardens, and the water permeability is poor, so it is best to mix it with river sand when using. It is mostly used to cut tree-like leafy flowers and acid-loving flowers that are not easy to root.

Look what kind of plant it is.

Cuttings are better with plain soil, vermiculite, sand, perlite, peat, plant ash, etc.

Common cutting methods are as follows:

1. Shoot cuttings.

It is the use of semi-lignified branches for cuttings. It is generally suitable for the propagation of evergreen plants and some deciduous plants or herbaceous flowers, such as yueji, rhododendron, camellia, gardenia, chrysanthemum, a bunch of red, rubber trees, monstera, etc. The suitable time for shoot cuttings is generally in the rainy season, and the specific operation method varies somewhat depending on the plant species, but the general steps are the same.

Semi-lignified shoots with a growth and development of vigorous, 6 10 cm long (10 15 cm for some species) and free of diseases and pests were selected as cuttings, the lower leaves were removed, only the uppermost few leaves were retained, and the base was cut into a wedge shape with a sharp blade. Cuttings depth 2 4 cm. The row spacing varies depending on the plant species, but can generally be 3 5 crn, or 5 10 cm.

After insertion, press the solid substrate slightly with your hand. After cuttings, they should be filled with water and covered with bamboo curtains. After that, keep the substrate moist often, and it can take root and survive in 15 to 20 days.

2. Hard branch cuttings.

It is a cuttings that are made from completely lignified branches. This method is suitable for the propagation of woody plants, and the season is generally carried out in early spring.

Choose well-growing, disease-free fully lignified shoots as cuttings, with a length of 15 20 cm, with flat upper incisions and oblique lower incisions, and generally do not retain leaves. The depth of cuttings is generally 1 2 2 3 of the length of the cuttings, or only the apical buds can be exposed. The row spacing is generally 20 25 cm or 25 30 cm.

After insertion, slightly press the solid soil and irrigate it thoroughly. Generally, it is necessary to cover it with a film to maintain moisture, and pay attention to timely irrigation. Generally, it can take root and survive in about 1 month, and the film can be removed after a month for routine management.

3. Leaf cuttings. Taking advantage of the regenerative function of leaf veins and petioles to grow adventitious roots and adventitious buds, the leaf is used as cuttings to propagate new individuals called leaf cuttings. Leaf cuttings are generally performed in greenhouses, and the environmental conditions required are the same as those for shoot cuttings.

Cuttings teach you to choose soil, the almighty formula hurry up and collect it, it will always be used.

The best substrate for cuttings is pure coarse sand or a mixture of sand and peat, with a volume ratio of 3 1, and the substrate should be sterilized and disinfected to ensure that the substrate of cuttings is loose, breathable, moisturizing, and virus-free. And should be according to the thickness of the cuttings and the difficulty of roots, choose the substrate of appropriate particle size, the thick and root-prone varieties of cuttings can be used with a relatively rough substrate to increase porosity, the bottom layer of the thinner and not easy to take root can be selected with a rougher substrate, and then a layer of fine substrate is laid on top.

Fresh plain loess without fertilizer and weed seeds is most suitable. Clean river sand, perlite can be used as a substrate for cuttings. It's just that different substrates have different water retention and different watering intervals.

The soil of the cuttings requires good drainage. Good breathability. Proper water storage without humus. Therefore, sandy soil or plain sand or rice bran ash are generally chosen.

Cuttings substrate requires materials that are well ventilated, easy to moisturize, and well drained. Commonly used species are river sand, peat, garden soil, vermiculite and perlite.

River sand: Coarse quartz sand that does not contain organic matter is preferred. Good drainage ventilation and easy absorption; The disadvantage is poor water retention.

Peat: strong water retention, acidic (or slightly acidic) reaction, can be mixed with coarse sand.

Vermiculite and perlite: good aeration, strong water retention, can be mixed with peat. It is suitable for most flower cuttings with perennial roots.

Garden soil: rich in organic matter, high-quality loose garden soil, after sun exposure, can be used as open field seedbed cuttings substrate after raking.

Use 3 kinds of "substrates" and cut a pot of crab claw orchid to see which pot takes root the fastest.

Flower cuttings for seedlings should choose a substrate that adapts to plant physiology. For those flowers and trees that are not suitable for cuttings in the soil, the following substrate cuttings should be selected:

River sand river sand is better than coarse stone without organic matter, which has the characteristics of good aeration, easy to absorb heat, fast heating, and conducive to rooting. However, it has poor water retention and should be replenished in time. This river sand should be cut for plants native to tropical deserts, such as cacti, epiphyllum and so on.

Plain soil, fine sand, vermiculite, and water can all be used as a substrate for cuttings, so choose according to your needs.
