How much are American red maple seeds per jin?
Do you know about these? The topic of American red maple seeds price per jin and the seedling raising technology of red maple seeds, let's learn about it together next.
Currently, the market for American red maple seedlings is in a relatively chaotic state. The market prices for American red maple seedlings vary by region, leading to a bottleneck period in the cultivation of American red maple. There are many low-priced American red maple seedlings on the market, but the number of purebred varieties is scarce, so we need to increase the production of purebred American red maple seedlings. So how to raise American red maple seedlings? What kind of seedlings are of good quality? Let's learn about the seedling raising technology of American red maple today.
1. Selection and Preparation of Seedling Site
American red maple is adaptable to the environment, with characteristics of loving moisture, drought resistance, and cold resistance. Generally, we choose to plant in areas with strong soil moisture and fertility retention, good permeability, convenient irrigation conditions, and sunny locations for American red maple seedlings. Secondly, the soil pH of the planting site should be slightly acidic, with a sand loam soil around six to seven. Before sowing, deeply turn the soil at least thirty centimeters, clean up the debris in the field, and disinfect to reduce the harm of some diseases and pests to American red maple. Then add 5,000 kilograms of organic fertilizer to the soil, mix with 100 kilograms of ternary compound fertilizer, turn the soil again, and finally level the soil, dig ditches, and prepare for planting.
2. Seed Treatment and Germination
Usually, American red maple seeds need to be treated before sowing to improve their germination rate. First, prepare an appropriate amount of river sand, moisten it with water, then mix the American red maple seeds evenly in the wet sand, and place them in an environment with a temperature of three to four degrees for low-temperature sand storage. During sand storage, we need to check regularly. It's not necessary to wait for all seeds to germinate before planting; as soon as any germinated seeds are found, they can be taken out for sowing.
3. Sowing Time and Method
American red maple can be sown in spring and autumn, but we usually sow between March and April every year, as the germination rate and survival rate are higher during this period. Autumn sowing is usually between August and October every year. Before sowing, water the seedling site, then evenly spread the seeds on the seedbed and cover them with a thin layer of soil. If you want to speed up germination, you can also set up a plastic greenhouse or cover with plastic film, straw, etc.; however, be sure to ventilate. Under normal management, the red maple seedlings can usually emerge in about half a month after sowing.
4. Seedling Management
After the American red maple seedlings emerge, their growth rate is very slow, and their resistance is also very poor, so they need careful attention. We should often spray water on the red maple seedlings to keep the soil moist and, during this period, promptly clear the weeds growing in the field. Of course, you can also do some light cultivation and earthing to prevent lodging and improve soil permeability, promoting nutrient absorption and utilization. When the red maple seedlings grow to about fifteen centimeters, thinning should be carried out, removing some diseased and weak seedlings, as well as small seedlings, and also doing some appropriate seedling supplementation. Finally, based on the growth of the red maple seedlings, apply topdressing to promote the growth of the seedlings and improve their resistance. When diseases and pests occur, spray pesticides in a timely manner.
Today's introduction to the seedling raising technology of American red maple is here, I hope everyone can cultivate better American red maple seedlings in the future planting process.
