Introduction to sowing and cuttage propagation of Chrysanthemum morifolium

Chrysanthemum chrysanthemum like high temperature, dry and sunny environment, strong adaptability, but not resistant to acid soil. Chrysanthemum morifolium is a good wind-proof and sand-fixing plant, which is usually planted as an annual herbaceous plant with a flowering period from July to October. Artificial propagation can be done by sowing and cutting.

First, sowing and reproduction

Often sowing in summer, the sowing substrate for disinfection, the best way is to put it into the pot to fry hot, what diseases and insects can be scalded to death. Soak the seeds in warm hot water (the temperature is about the same as facial wash) for 3 to 10 hours until the seeds absorb water and expand. For common seeds that germinate easily, this work does not have to be done. For tiny seeds that are difficult to pick up with hands or other tools, wet one end of the toothpick with water, stick the seeds one by one on the surface of the matrix, cover the substrate 1 cm thick, and then put the seeding pot into the water. The depth of the water is 1 stroke 2 feet 2 tap 3 of the height of the flowerpot, allowing the water to soak up slowly. For larger seeds that can be picked up by hand or other tools, put the seeds directly into the substrate and order them at a distance of 3 × 3 cm. After sowing, the substrate was covered, and the thickness of the cover was 2-3 times that of the seed. After sowing, the sowing matrix can be wet with sprayer and fine hole shower, and then drenched later when the potted soil is slightly dry, but still pay attention not to watering too hard, so as not to wash the seeds up; management after sowing: after the seedlings are unearthed, the film should be opened in time, and let the seedlings receive the sun's light before 9:30 every morning or after 3:30 in the afternoon, otherwise the seedlings will grow very weakly. After most of the seeds come out, they need to plant seedlings properly: pull out the diseased and unhealthy seedlings, so that the seedlings left behind have a certain space between each other; when most of the seedlings grow 3 or more leaves, they can be transplanted into the pot.

2. Cutting propagation

The branches used for cutting are called cuttings. Usually combined with the heart-picking work, the sturdy, disease-free top tip is taken as a cuttage, and the top tip is cut directly. After cutting, attention should be paid to the following management: temperature: the optimum temperature for rooting of cuttings is 18 ℃ ~ 25 ℃, which is lower than 18 ℃, and it is difficult and slow for cuttings to take root; when the temperature is higher than 25 ℃, the cuttings are easy to be infected by pathogens and rot, and the higher the temperature, the greater the proportion of rot. When there is a low temperature after cutting, the heat preservation measure is mainly to wrap the flowerpot or container used for cutting with thin film; when the temperature is too high after cutting, the cooling measure is mainly to shade the cuttings, to cover 50-80% of the sun, and at the same time, spray the cuttings 3-5 times a day, with more times of spraying when the temperature is higher in sunny days, lower temperatures and higher temperatures in rainy days, but less or no spraying times.

Introduction to the methods of sowing and propagation of Chrysanthemum morifolium

Tianren chrysanthemum, also known as tiger skin chrysanthemum, tiger skin chrysanthemum and so on, because of its strong drought tolerance, it is a very good windproof and sand plant, which is very suitable for planting in the courtyard. The common propagation methods of Chrysanthemum morifolium are sowing and cutting. the editor will introduce to you the methods of sowing and propagation and the maintenance and management methods after sowing.

Chrysanthemum morifolium

1. Sowing and reproduction: often sow seeds in summer and disinfect the substrate used for sowing. The best way is to put it in a pot and stir-fry it, so that any diseases and insects can be scalded to death. Soak the seeds in warm hot water (the temperature is about the same as facial wash) for 3 to 10 hours until the seeds absorb water and expand.

2. Management after sowing: after the seedlings are unearthed after sowing, the film should be opened in time, and the seedlings should be exposed to the sun before 9:30 every morning or after 3:30 in the afternoon, otherwise the seedlings will grow very weakly; after most seeds come out, seedlings need to be properly interspersed: pull out the diseased and unhealthy seedlings, so that there is some space between the seedlings left behind. When most of the seedlings have three or more leaves, they can be transplanted into the pot.

How to reproduce Chrysanthemum morifolium

How to reproduce chrysanthemum? The annual herb of Chrysanthemum morifolium generally uses the methods of seed sowing and cutting propagation to reproduce. Because the appearance of Chrysanthemum morifolium is very beautiful, many flower friends will raise a few at home. In addition, Chrysanthemum morifolium is also a good breeding flower plant. Let's take a look at the sowing and cutting propagation methods of Chrysanthemum.

Sowing and propagation methods of Chrysanthemum morifolium 1. Sowing season and seed disinfection

Often sowing in summer, the sowing substrate for disinfection, the best way is to put it into the pot to fry hot, what diseases and insects can be scalded to death. Soak the seeds in warm hot water (the temperature is about the same as facial wash) for 10 hours until the seeds absorb water and swell up. For common seeds that germinate easily, this work does not have to be done.

2. Seed planting

For tiny seeds that are difficult to pick up with hands or other tools, wet one end of the toothpick with water, stick the seeds one by one on the surface of the matrix, cover the substrate 1 cm thick, and then put the seeding pot into the water. The depth of the water is 1 hand, 2 meters, 2 hands, 3, and let the water soak up slowly.

For larger seeds that can be picked up by hand or other tools, put the seeds directly into the substrate and order them at a distance of 3 × 3 cm. After sowing, the substrate was covered, and the thickness of the cover was 3 times that of the seed. After sowing, you can use sprayers and fine-hole showers to wet the sowing matrix, and later, when the basin soil is slightly dry, you should still pay attention to the watering strength not to wash the seeds up.

3. Maintenance after emergence

After sowing, the seedlings should be unearthed in time, and the seedlings should be exposed to the sun before 9:30 in the morning or after 3:30 in the afternoon, otherwise the seedlings will grow very weakly. After most of the seeds have come out, they need to plant seedlings properly. Pull out the diseased and unhealthy seedlings so that the seedlings left behind have a certain amount of space between each other. When most of the seedlings have three or more leaves, they can be transplanted into the pot.

4. Seedling transplanting

When the seedlings are installed in a basin, first put a coarse-grained matrix or ceramsite 2mm thick at the bottom of the basin as a filter layer, and sprinkle a layer of fully mature organic fertilizer as base fertilizer with a thickness of about 1m / 2cm, then cover it with a substrate with a thickness of about 1m / 2cm, and then put in the plant to separate the fertilizer from the root system to avoid burning roots. The substrate used in the basin can be vegetable garden soil: slag = 3RU 1, or garden soil: medium coarse river sand: sawdust (slag) = 4:1:2.

5. Watering in the basin

Pour water once after putting on the basin and keep it in a shady environment for a week. When transplanting the seedlings, first dig the planting hole, sprinkle a layer of organic fertilizer at the bottom of the planting hole as the base fertilizer (base fertilizer), the thickness is about 4mur6cm, and then cover a layer of soil and put it into the seedlings to separate the fertilizer from the roots and avoid burning roots. After putting it into the seedling, backfill the soil, cover the root system, and trample the soil with your feet and water it once.

Methods of Cuttage Propagation of Chrysanthemum morifolium 1. Selection of cutting branches

The branches used for cutting are called cuttings. Usually combined with the heart-picking work, the sturdy, disease-free top tip is taken as a cuttage, and the top tip is cut directly. The optimum temperature for rooting of cuttings was 18 ℃-25 ℃, which was lower than 18 ℃. The rooting of cuttings was difficult and slow. When the cuttings were higher than 25 ℃, the cuttings were susceptible to bacterial infection and rot, and the higher the temperature, the greater the proportion of rot.

2. Cutting maintenance and management.

When there is a low temperature after cutting, the main measure of heat preservation is to wrap the flowerpots or containers used for cutting with thin film. When the temperature is too high after cutting, the main measure to cool the cuttings is to shade the cuttings, to cover 50% of the sun. At the same time, spray the cuttings 5 times a day, and there are more times of spraying when the temperature is higher in sunny days. On rainy days, the temperature is lower and the temperature is higher, but the times of spraying are less or no.
