Seedling raising techniques of Acer truncatum

At present, the market for American red maple seedlings is in a relatively chaotic state. The market price of American red maple seedlings varies from region to region, which leads to the bottleneck period of American red maple planting. There are a lot of low priced American red maple seedlings on the market, but pure varieties are scarce, so we need to increase the yield of pure American red maple seedlings. So how does the American red maple grow? How to breed seedlings of good quality? Today we will learn the breeding technology of American red maple together.

1. Selection and arrangement of seedling land

American red maple has strong adaptability to the environment, with the characteristics of wet, drought and cold resistance. Under normal circumstances, we will choose soil with strong water and fertilizer conservation, good permeability, convenient irrigation conditions and sunny areas for planting. Secondly, the soil pH of the planting area is preferably slightly acidic, and the PH value is about six to seven sandy soils. Before sowing, the soil should be deeply ploughed at least 30 cm, and the debris in the field should be cleaned and disinfected, so as to reduce the harm of some pests and diseases to American red maple. Then add 5,000 kilograms of organic fertilizer to the soil, and then turn it over again with 100 jin of ternary compound fertilizer. Finally, level the soil, ditch it, and wait for planting.

2. Seed treatment and germination

The seeds of American red maple generally need to be treated before sowing, which can improve its germination rate. First, prepare an appropriate amount of river sand, wet with water, and then put the seeds of American red maple into wet sand to mix evenly, and then place them in an environment with a temperature of three or four degrees for low-temperature sand storage. During the sand storage period, we should check it regularly. We don't have to wait for it to germinate before planting. Once we find budding seeds, we can take them out and sow them.

3. Sowing time and method

American red maple can be sown in spring and fall, but we most often sow between March and April each year, when the emergence rate and survival rate are higher. Autumn is usually between August and October of each year. Before sowing, the seedlings should be watered, and then the seeds should be evenly scattered on the seedbed, and then covered with a thin layer of soil to cover the seeds. If you want to improve its emergence speed, we can also build plastic sheds, or cover film, straw, etc.; but pay attention to ventilation. Under normal management, red maple seedlings can be produced more than half a month after sowing.

4. Seedling management

After the American red maple seedlings are unearthed, its growth rate is very slow, and the resistance is also very poor, so it needs careful care. We should often spray water on red maple seedlings to make the soil have a certain humidity. At the same time, we should clean up the weeds growing in the field in time during this period. Of course, appropriate loosening and cultivation can also be carried out, which can avoid lodging, improve soil permeability and promote nutrient absorption and utilization. When the red maple seedlings grow to about 15 cm, they should be thinned, some pests, emaciated seedlings and seedlings should be removed, and appropriate supplementary seedlings should be carried out at the same time. Finally, according to the growth condition of the red maple seedlings, topdressing is carried out to promote the growth of the seedlings and improve the resistance of the seedlings. When pests and diseases occur, spraying should be done in time.

Today, Xiaobian wants to introduce to you the seedling technology of American red maple here, I hope you can cultivate more high-quality American red maple seedlings in the later planting process.
