How to propagate Photinia rugosa, cutting technique / learn seven steps to propagate easily

With more and more people planting red leaf heather, red leaf heather propagation method has also attracted much attention, as a strong germination, accelerated growth of leaf plants, red leaf heather how to reproduce more appropriate? Let's take a look at the red leaf heather cutting technology that we care about.

How does red carpet reproduce?

Red leaf heather is native to Southeast Asia and North America. Due to its unique growth characteristics, its reproduction method is also different. How does red leaf heather reproduce? Tissue culture and cuttage propagation are the common methods, among which the cuttage technology of Photinia rubra is relatively mature and low cost.

Tissue Culture of Photinia rubra

The so-called tissue culture refers to the isolation of tissues and cells that meet the requirements from plants, and then cultured under artificial control conditions in an aseptic environment to obtain complete regenerated plants. This method requires professional technology and corresponding facilities, so the cost is relatively high and is generally not commonly used.

Cutting Techniques of Photinia rubra

I. Preparations

How does red leaf heather propagate when using cuttings? First of all, we need to make preparations. Should choose higher terrain, flat, good drainage, deep soil layer and. The basic quality of the seedbed should be disinfected with a disinfectant machine to prevent the occurrence of pests and diseases, and can be prepared according to the requirements of the soil in the cultivation method of red leaf heather.

II. Determination of time

In red leaf heather cutting technology, the choice of time is relatively flexible, there are spring planting in early March, summer planting in early June and autumn planting in early September, but also according to climate conditions to choose the right time, such as in some places in the south in November can still be cutting.

III. Cutting branches

For cutting branches, should be semi-lignified shoots or lignified branches of the year, cut into a leaf a bud, the length of 3-4 cm is the best, the incision must be smooth.

IV. Rooting treatment

In order to shorten the rooting time after cuttage, rooting treatment should be carried out before cuttage. Generally, the rooting agent is mixed into a solution to soak the cuttings, such as biochemical raw materials such as naphthylacetic acid, indolebutyric acid, etc., and two thirds of the cuttings are put into the solution for soaking for 1 second and then taken out, which can shorten the rooting time to 7-15 days.

V. Cutting

This is a red leaf Photinia cutting technology in a more important link. When cutting, first irrigate the seedbed with water, then insert two-thirds of the cuttings into the seedbed, and let the top leaves receive uniform light in the same direction.

VI. Post-management

1. After cuttage, 600-800 times solution of thiophane methyl and chlorothalonil can be sprayed for disease prevention. Then keep the matrix moist, ensure that the water content is about 60%, the temperature is controlled below 38 degrees, and the humidity is about 95%. If the temperature is too high, spray can cool down, and when the light is too strong, shade should be timely.

2, after cutting generally 7-15 days of natural roots, after rooting can reduce the moisture content of the matrix, generally in 40%, transmittance should also be maintained at about 50%.

3. When all the ears are rooted and 2-3 new leaves grow, the shade net can be removed, and then the seedlings can be refined. In this process, a low concentration of water-soluble fertilizer can be sprayed on the leaves.

How does Red Hat grow? Methods and steps of cutting propagation of Photinia rubra

Introduction: There are many methods of red leaf heather propagation, the most common is cuttage propagation, cuttage operation is simple, survival rate is high, cost is lower, can be produced in batches, is the most common seedling cultivation method on the market, the following first agricultural classics Xiaobian for you to introduce red leaf heather cuttage propagation methods and steps!

Red leaf heather cutting propagation method and steps:

Cutting of Photinia rubra

1. Cutting facilities. Adopt monomer greenhouse cuttage, want to cover greenhouse film, add sunshade net. After the ground in the shed is leveled, a ground cuttage seedbed is established. Seedbed width of about 100 cm, around the installation of 10 - 12 cm high baffle.

2. Preparation of seedbed. The planting soil is loose, fertile, slightly acidic to neutral, easy to irrigate and well drained. Before planting, 3 000 kg of decomposed manure and 50 kg of calcium superphosphate are applied per mu, the soil is tilled to a depth of more than 25 cm, and pesticides are applied to control underground pests. After ploughing, the soil will be leveled, drainage ditch will be opened, and seedbed will be made. The bed width is about 1 meter. Seedbed bottom spread a layer of fine sand to facilitate drainage, cuttage substrate available vermiculite plus peat, or with clean yellow soil plus fine sand. Seedbeds and substrates should be disinfected with fungicides and insecticides to prevent pests and diseases.

3. Cutting time. Spring planting in early March, summer planting in early June and autumn planting in early September.

4. Cutting of cuttings. Use semi-lignified shoots or lignified branches of the current year, cut into a leaf and a bud, 3 - 4 cm in length, and cut smoothly.

5. Cutting treatment. After cutting, pay attention to moisture, try to cut with cutting. Before cuttage, the incision was treated with rooting agent to accelerate rooting speed and improve survival rate. The cutting depth is 3 cm and the density is 400 plants per square meter. After inserting, pour water thoroughly immediately, spray the leaves with carbendazim and anthrax mixture.

6. Post-insertion management. After cutting, check the seedbed frequently, keep the moisture content of the substrate at about 60%, keep the air humidity in the shed above 95%, control the temperature in the shed below 38℃, if the temperature is too high, spray cooling. From cuttings to root germination before all shade. After 15 days, some cuttings began to take root, and the moisture content of the substrate should be appropriately reduced, generally maintained at about 40c70. When more than 50% cuttings begin to take root, the film can be gradually opened for ventilation, and the shade transmittance is about 50%. When all the ears are rooted and more than 50% of them are leafed, the shading net and film of the greenhouse are gradually removed, and the seedling training begins. Foliar fertilizer or low concentration water-soluble chemical fertilizer can be applied in combination to promote the healthy growth of cuttings.

How does red leaf heather reproduce? Red leaf heather propagation method

There are two main propagation methods of Photinia rubra: tissue culture and cuttage. Tissue culture on facilities and professional technology requirements and costs are high, most nurseries and growers are not suitable, Xiaobian here introduces a set of low cost, easy to operate, high survival rate, can be produced in ordinary plastic greenhouse cutting propagation technology.

Cutting facilities and seedbed preparation

Adopt monomer greenhouse cuttage, want to cover greenhouse film, add shade net. After the ground in the shed is leveled, a ground cuttage seedbed is established. Seedbed width of about 100 cm, around the installation of 10 to 12 cm high baffle. Seedbed bottom spread a layer of fine sand to facilitate drainage, cuttage substrate available vermiculite plus peat, or with clean yellow soil plus fine sand. Seedbeds and substrates should be disinfected with fungicides and insecticides to prevent pests and diseases.

cutting time

The cutting time of Photinia rubra is spring cutting in early March, summer cutting in early June and autumn cutting in early September.

Post-cutting management

After cutting, check the seedbed frequently, keep the moisture content of the substrate at about 60%, keep the air humidity in the shed above 95%, control the temperature in the shed below 38℃, if the temperature is too high, spray cooling. Shading is required from cutting to rooting.

After 15 days, some cuttings began to take root, and the moisture content of the substrate should be appropriately reduced, generally maintained at about 40%. When more than 50% cuttings begin to root, the film can be gradually opened for ventilation, and the shade transmittance is about 50%.

When all the ears have roots and more than 50% of them have leaves, gradually remove the shade net and film of the greenhouse and start seedling training. Foliar fertilizer or low concentration water-soluble chemical fertilizer can be applied in combination to promote the healthy growth of cuttings.
