Albizia Garden Purpose: Albizia has an open crown, slender leaves like feathers, and bright red flowers. It is a beautiful shade tree and street tree. It is suitable for planting in front of houses, lawns and forest edges. It has strong resistance to toxic gases and can be used as garden trees, street trees, landscape trees, waterfront green trees, factory green trees and ecological protection trees.
Sowing and propagation: Albizia is often used for sowing and propagation. Seeds are collected from September to October. When collecting seeds, you should choose pods with full grains and free of diseases and insect pests, and thresh them in the sun, and store them in a dry and ventilated place to prevent mold.
Seedlings are grown in spring, soak the seeds for 8-10h before sowing, and then take them out for sowing. Ditch and drill, ditch distance 60cm, cover soil 2-3cm, keep the border soil moist after sowing, and germinate about 10d. The seed amount for 1h㎡ is about 150kg. After the seedlings emerge, the management work such as weeding, soil loosening and top dressing should be strengthened. Transplant in spring or autumn in the second year, with a plant spacing of 3-5m. For 2-3 years after transplanting, weed the pine nests every spring and autumn to promote growth.
Seed treatment: From March to April of the following year, the seeds can be sown after treatment. Because the seed coat of Albizia julibrissin is hard, in order to make the seeds germinate neatly and unearth quickly, it needs to be soaked in 0.5% potassium permanganate cold aqueous solution for 2 hours 2 weeks before sowing, and rinse with clean water after removal and soak the seeds in hot water at about 80℃ 30s (the longest cannot exceed 1min, otherwise it will affect the germination rate), sowing can be carried out after 24h. Using this method, the germination rate can reach 80%-90%, and the growth after emergence is strong and not easy to get sick.
