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.

Propagation methods of Chrysanthemum morifolium

Propagation methods of Chrysanthemum morifolium

There are generally three propagation methods of Chrysanthemum morifolium, which are sowing and cutting. Generally speaking, the sowing method is commonly used and is most familiar to everyone. Let's study separately.

Sowing and reproduction

Sowing and reproduction are often carried out in summer. The seeds and substrates should be treated before sowing. The matrix should be disinfected in order to kill diseases and insect pests. The seeds should be soaked in warm water for 3 to 10 hours, depending on the situation, as long as the seeds expand. Some seeds are small and difficult to sow by hand, they can be clipped with tweezers and placed on the surface of the substrate. After all the seeds are sown, a layer of matrix should be attached, which is about one centimeter thick.

After sowing, you can choose to soak the substrate gently with spray to prevent the seeds from being washed out due to excessive watering. Finally, cover with a thin film. After sowing, uncover the film when the seedlings are unearthed, and let the seedlings receive light regularly, paying attention to avoid strong light, for example, before 9 o'clock.

Cuttage propagation

Cutting propagation is also a relatively simple method of propagation. The material to be selected for cutting is called cutting. cuttings usually choose top tips that grow well and are free from diseases and insect pests. The cutting temperature should be kept between 18 ℃ and 25 ℃. Cuttings should pay attention to disinfection, if the temperature is too high, it is easy to lead to infection. At the same time, in case of low temperature climate, it can be covered with thin film to increase the ambient temperature. Shade is also necessary to cover more than half of the sun.

Matters needing attention in the breeding of Chrysanthemum morifolium

After sowing and reproduction, we should pay attention to take off the film and give proper light after the seedlings are unearthed, and avoid the period of strong light at noon, usually from 9: 00 a.m. to 3: 00 p.m., in the middle of this period of time should be placed in a cool place. After the seedlings grow out one after another, it is necessary to make appropriate interseedlings, that is, to pull out the poorly growing seedlings, leaving room for growth and sufficient water and nutrients for the well-growing seedlings.

The temperature should be controlled during cutting. too low temperature is not conducive to the growth and survival of cuttings after cutting. if the temperature is too high, the cutting mouth of cuttings will be infected with bacteria. Appropriate shading should also be done after cutting, about half of the shading effect should be more than half, and the number of water spraying should be increased when the temperature is high.
