Camellia, also known as camellia, is a general term for a variety of plants and horticultural varieties of Theaceae and Camellia. It is one of the top ten famous flowers in China with beautiful plant shape, thick green leaves and colorful flowers. But most of the camellia trees are mostly cuttings or grafts, rarely with seed planting, today Xiaobian brought you the camellia seed planting method, now please take a look down with me!
How to plant camellia seeds the basic operation steps of seed planting 1. Seed harvesting and storage: in autumn, when the fruit is slightly cracked, it should be harvested immediately, put in the indoor cool and ventilated place to dry, and take out the seeds after the fruit is naturally cracked. The seeds need to be sown immediately after collection, and can also be treated by sand accumulation. After cleaning and disinfecting the fine sand with clean water, lay the seeds and fine sand layer by layer in an appropriate container, cover the upper layer with 5cm thick fine sand, and then bury the container in the soil, and regularly check to prevent mildew and rat damage.
2、 Seed treatment before sowing: camellia seed coat is hard and needs to be treated to make the seeds germinate quickly and orderly. It can be treated by the following methods:
(1) The seed coat was cut with a sharp knife;
(2) The seeds were soaked in 40-50 ℃ warm water for half an hour, and then soaked in 20-25 ℃ water for 5-6 days;
(3) It was soaked in gibberellin solution of 100 μ g / g for one day and night.
3、 Sowing: when the amount of seeds is large, the seedbed can be used for drilling. The seedbed is 1 m wide and 1.5-20 cm long. The seed bud eye is downward and put into a ditch 5 cm deep. The plant spacing is 1-2 cm. After sowing, water is poured once. When the amount of seeds is small, the seeds can be sown in the basin. The thickness of soil covering is 0.5-1cm, and the water can be sprayed gently with a sprinkling pot.
Four, after sowing Management: after sowing, plastic film or glass can be used to cover the seedbed and flowerpot to keep the humidity, keep the temperature at 18-25 degrees, and give sufficient light (avoid direct light). Ventilate the air properly every day, weed the plants in time, prevent and control underground pests, and use 0.1% Potassium Permanganate spray to disinfect the fungus. When the seedlings grow to 3-4 leaves, they should be transplanted into the pot. Choose a pot with 7-10CM diameter, one plant in each pot, and place it in a cool and ventilated place. Spray water with a watering can. After rooting for about a week, gradually increase the light and apply a thin liquid fertilizer.
Daily maintenance of Camellia seedlings from camellia seeds
1. Lighting: full light is available most of the year, and partial shading is required in summer.
2. Water and fertilizer management: there is a saying on the Internet that there is no need to see dry and wet. But he still followed this method, increasing the frequency of watering in flowering period, although it can promote flowering, but the flowering period will also be shortened. Don't be too big. Use nutrition for less than three years. Use a one gallon pot for three to five years. This way, the drying and wetting cycle is easy to control.
Fertilization is necessary, but Camellia does not like large amount of water and fertilizer. If liquid fertilizer is used, it will usually be diluted to half of the recommended concentration. The basic nitrogen fertilizer is compound organic fertilizer, mixed with some bone meal as phosphorus and potassium fertilizer. Do not use livestock manure to prevent burning seedlings. Camellia needs weak acid soil, plant ash and rice husk charcoal are alkaline, not suitable for Camellia. Watering flowers with tap water increased the alkalinity of the medium, so he often forgot to apply ferrous sulfate every month, so he mixed sulfur powder in the soil. Put some quick acting phosphate fertilizer in the early stage of pregnancy.
3. Common diseases and insect pests: the most common is that there are scale insects on the back of leaves, which are black and yellow, about 1 mm in size. Once found, it is the easiest way to wipe with paper towel. If there is cotton flocculent substance on the branch, which is blowing cotton scale insect, it can be sprayed on the leaf. Conventional insecticides are OK.
Camellia also has red spider, but it is rare. Without strong pesticides such as dimethoate or dichlorvos, it is very difficult to eradicate spider mites. We can only avoid camellia and other plants together to reduce the probability of infection. Some fungi may cause rotten roots or leaves to appear spots, which can be controlled by methylthiophanate. I think this ingredient has better effect than carbendazim, just root irrigation.
4. The phenomenon of drooping leaves and falling leaves is common in summer, which is mainly caused by water, root rot and high temperature. If the reason is not clear, the plant should be moved to the shady cool place, can spray antifungal drugs, do not water.
5. Flowering treatment: he tried to use gibberellin treatment, cut off half of the leaf bud beside the flower bud, and apply a small amount of 0.1% Gibberellin on the stump, which can increase the flower diameter. But it is easy to cause bud burst, or poor opening, or the Wen petal opening into Wu petal.
Sparse bud: if it is about two years of cuttings, do not leave a bud. For seedlings of about four years old, he usually leaves one bud every other branch, and only leaves the top bud on the strong branch. If the buds are thinned and the water and fertilizer management is appropriate, the buds will not fall or scorch.
6. Pruning: too long plant type, cut off a length can promote branching. Some varieties, such as xiaotaohong, have compact plant type and need to pay attention to some diseased branches.
