What is the flower language and meaning of camellia?

Flower language: ideal love and humility

Species: Theaceae

Origin: Japan

Colors: pink, red and white

Flowering: late autumn to winter

Alias: Zhuang Ji

Camellia is named by a German botanist and spread all over the world.

It always opens quietly in the yard when the weather is a little cold in late autumn. Camellia is not like a pile. The whole flower falls, but the petals fade slowly until the end of life.

Isn't a cautious death the same as people's attitude towards their ideal partner? So gradually camellias became the spokesmen to express their love for women.

In the winter when almost all the flowers wither, the red camellia is particularly warm and full of business. Moreover, planting in the garden can also make people appreciate her faint floral fragrance.

★ Key points:

Camellia is a kind of plant that can be easily seen in general gardens. Because dark green leaves are also beautiful, you can also use only leaves to set off other flowers. But flowers fall off easily.

breeding method

Camellia usually propagates by cutting, grafting, layering, sowing and tissue culture. Cutting is usually the main method.

Cutting propagation method

Camellia has strong regeneration ability of stems and branches, so cutting and grafting have high survival rate, fast propagation speed, convenient operation and high economic benefit, and are widely used in production. Camellia can be cut all year round under good growth conditions, generally in summer and autumn, and the survival rate of cutting is high in the rainy season around June, so it is high temperature and high humidity, which is conducive to the rooting and germination of cuttings.

1, pot cutting method

Drill 1-3 drainage holes at the bottom of the flowerpot, wooden box or plastic box for cutting, each hole is 2-3 cm in size, and good drainage is required. Cover the hole with broken tiles, with a layer of pebbles at the bottom, a layer of coarse sand at the middle and 5- 10 cm culture soil at the top. Usually, the culture soil is acidic red-yellow soil with pH value of 5-6.5. If the viscosity is too high, fine sand or sawdust can be added. If conditions permit, appropriate amount of humus, vermiculite, decomposed organic fertilizer or phosphate fertilizer and bone meal are mixed into the culture soil. When the soil is slightly alkaline, add ferrous sulfate solution to adjust it to make it slightly acidic. Culture soil can be exposed to the sun for a few days, or it can be disinfected with formaldehyde solution and then suffocated with plastic film for a few days, all of which have the effect of sterilization and disinfection.

When the pot or box is filled with culture soil, it should be higher than the surface of the pot or box to make it into a steamed bread shape, so as to prevent water accumulation in the pot or box, and at the same time, it is beneficial to ventilation of cuttings and improve survival rate. When cutting, gently press the culture soil with your fingers, and water it with a small mouth basin for shading and moisturizing management.

2. Seedbed cutting method

It is advisable to choose acidic to slightly acidic sandy loam as seedbed. After ploughing, the seedbed width is about 1.2m, the ditch width is 40-50cm, and the border height is 20cm. Pruning, harrowing, spraying medicine on the bed surface for disinfection and covering with film for 2-3 days are beneficial to the prevention and control of pests and diseases. Before cutting, set up a scaffolding with a height of 1.5-2 meters with cement columns or bamboo, cover it with a reed curtain or a black shading net (shading rate is 60-70%), hang it on the ground from top to bottom, fix it, and give consideration to shading, wind protection and moisture retention. If the plastic greenhouse is used for cutting seedlings, four small arch sheds with a height of 30-40 cm and a width of 80 cm can be built in the greenhouse, and the distance between the small arch sheds is about 50 cm, and the sun-shading net is covered after cutting. When cutting, pay attention to the orderly arrangement of leaves, pour enough planting water after cutting, and cover the small arch shed with a plastic film, which can improve the moisturizing effect.

3. Full-light fog cutting method

All-light fog cutting method needs certain facilities and production scale, with low seedling cost, fast rooting and high survival rate.

All-light fog cuttage seedbed mostly adopts matrix material or fine sand, with stones under it and drainage facilities at the bottom. Spraying equipment is installed on the seedbed, and measures such as setting interval spraying, maintaining relative humidity and adjusting seedbed temperature are taken to ensure the normal water absorption of cuttings and prevent cuttings and leaf buds from drying up.

transplant

It is often used for cutting varieties that are difficult to take root or have few propagation materials. The survival rate of grafting is the highest in May-June, when the new buds are semi-qualitative and germinate quickly after grafting. Camellia oleifera is the main rootstock, which was harvested in June+10 in 5438, stored in sand in winter and sown in early April of the following year. When the seedlings grow to 4-5 cm, they can be grafted. Cut off the germ part of the rootstock with a blade, split it vertically upwards along the pith center of the cross section of the embryonic axis, then take a section of camellia scion, cut the base below this section into a right-angled wedge shape, immediately insert the cut scion into the bottom of the split part of the rootstock, align it with the cambium on both sides, tie it tightly with cotton thread, and put on a clean plastic bag. It takes about 40 days to remove the pocket, and about 60 days to germinate and sprout.
