Where to buy copper coin eucalyptus seeds and how to grow seedlings?
Copper coin eucalyptus, also known as eucalyptus, is a plant with relatively high medicinal value and ornamental value. It likes warmth and is suitable for growing in places below 1900 m in altitude. It is often used to decorate weddings and various celebration events, and has broad market prospects and a relatively high selling price. With the acceleration of returning farmland to forest, the planting area of copper coin eucalyptus is also gradually increasing. So where are copper coin eucalyptus seeds sold? What are the seedling raising methods? Let's learn about them together.
Where are copper coin eucalyptus seeds sold?
Copper coin eucalyptus is extremely widely distributed, mainly centered in Oceania. In China, it has a certain distribution in Fujian, Guangxi, Guangdong, Yunnan and Sichuan. If there are planting production areas locally, then the chance of buying high-quality seeds is relatively greater. In addition to buying from production areas, many online platforms also sell seeds, but the quality varies, so you need to learn to distinguish carefully.
What are the seedling raising methods?
1. Seed collection and sowing
Collect seeds from November to December and sow in the following spring. Seeds can also be collected from July to August and sown in the same year. Every 100 kg of fruit can yield 1.5 kg of seeds. The 1000-seed weight is 2.8 g for blue gum and 1.5 g for straight-stem eucalyptus, and the seed germination rate reaches more than 90%.
2. Seedling raising methods
(1) Mother bed seedling raising: Choose fertile vegetable garden land as the seedbed site, sow in mid-March, carefully prepare the land and make beds, with bed width 1.2-1.6 m. Soak the seeds for 48 hours, mix them evenly with fine sand, and broadcast them on the seedbed, then cover with 1-2 cm of fine manure soil. Water thoroughly and cover with film. Seedlings can emerge 7-10 days after sowing.
(2) Nutrient bag seedling raising: After filling bags with nutrient soil, sow the soaked seeds in the bags (2-3 seeds per bag), then cover with a layer of fine manure, water thoroughly and cover with film. During the seedling growth period, thin the seedlings by pulling out the weak ones, leaving 1 plant per nutrient bag. When the seedlings grow to 10-20 cm tall, they can be transplanted.
3. Seedbed management
After the seedlings emerge, pull out all weeds in the seedbed. In addition, damping-off disease is likely to occur during the seedling stage. In the early stage of the disease, use 500 times dilution of 70% dexon per mu (100 kg of medicinal solution per mu), and spray or pour it on the seedbed 2-3 times, with each interval of 10-15 days.
4. Transplanting management
Transplant after the rainy season begins in early June. The planting hole is 40 cm deep and 40 cm in diameter, with 300 plants per mu (spacing 1 x 2 m). After planting, water thoroughly to settle the roots. The soil should be mounded higher than the ground surface to prevent water accumulation, root rot and soil compaction, which helps the young trees survive and grow.
5. Young tree tending
After the young trees survive, grazing should be prohibited, and weeds around the saplings should be removed in time. If conditions permit, loosen the soil to keep it loose. After the saplings grow for 2-3 years, prune once a year, removing the lower weak branches, which is beneficial for ventilation and light penetration and maintains the growth of the saplings. After 4 years, leaves can be harvested to extract aromatic oil.
It is understood that the growth period of eucalyptus copper coin eucalyptus is 7-8 months, and the main harvest is branches, which can obtain relatively high economic benefits in a relatively short time. The introduction and planting of this industry can effectively promote the upgrading of the planting industry and provide local growers with good economic development benefits.
