The propagation method of the latest red maple

Red maple is a kind of maple, also known as purple maple, red maple, red leaf, small chicken claw maple, etc., sexual like the sun, suitable for warm and humid climate, afraid of hot sun exposure, more cold-resistant, slightly drought-resistant, not resistant to waterlogging, suitable for fertile, loose and well-drained soil, valuable foliage trees, so often pot appreciation, let's take a look at the breeding methods of red maple!

Cutting propagation of red maple

Red maple can be propagated by cutting, especially in the production of small bonsai or potted plants, cutting is generally carried out during the Meiyu period from June to July, choose about 20 cm of strong headmaster as cuttings, quickly dipped in 1000ppm naphthalene acetic acid powder, cut into vermiculite or perlite and pond mud half of the matrix, after paying attention to shading, spraying moisture, about a month later can take root one after another. If there is full light spray, 2-year-old branches can also take root, and the survival rate is high. After transplantation, shading should be carried out, sunlight can be gradually accepted after half a month, and water and fertilizer management should be strengthened.

Method of sowing and breeding of red maple

Red maple seeds have no dormancy, can be sown in autumn or spring, now mainly introduce spring sowing. The suitable sowing time is from the middle of March to the middle of April. Before sowing, mix the seeds with wet sand at the ratio of 1:3 and put them under the condition of 3-5 ℃ for a month of low-temperature sand storage. During the stratification period, we should check and manage regularly, find germinated seeds and sow them in time. When sowing, first fill the border with enough bottom water, wait for the water to seep down and then sow, about 200 seeds per square meter. The fine soil of 0.5cm should be covered after sowing. In order to preserve the soil moisture and improve the soil temperature, the seeds can sprout early and neatly, and the plastic film or small arch shed can be covered. The arch shed should pay attention to ventilation, and the temperature should be shaded properly when the temperature exceeds 30 ℃ at noon. Generally, the seedlings will come out about 15-20 days after sowing.

Grafting and breeding of red maple

Acer truncatum can be propagated by grafting. 2 ~ 4-year-old Acer mongolica seedlings are used as rootstocks. Cutting should be carried out from March to April, and the height of rootstocks can be determined according to needs. This method is only used for a few precious varieties, which is carried out in the rainy season from May to June and cut off after falling leaves in autumn. Bud grafting is the most common, and the best time is from late May to late June and from late August to late September every year. Early summer is the peak period for branch growth. The full buds on the sunny short branches of the red maple are used as buds with a long petiole of 1 cm. After that, the temperature is getting higher and higher, although there is a plastic belt after it, but the buds and petioles are still exposed, and the skin of the red maple is thinner, and the bud is small, so it should be sprayed regularly to moisturize after pressing, in order to improve the survival rate. The method of bud grafting after autumn is basically the same. After a week, if the petiole is touched, it means it has survived, otherwise it has to be rejoined.
