How to plant albizzia seeds

Albizia tree, also known as velvet tree, its trees can be used to make furniture, flowers with high ornamental value, and symbolizes the harmony of husband and wife, family unity, deeply loved by the people of our country. So, how to plant albizzia seeds?

1. Collect seeds

Albizia is often sown and propagated, and seeds are collected from September to October. Pods with full seeds and free from diseases and insect pests should be selected, dried and stored in a dry and ventilated place to prevent mildew.

2. Seed treatment

Between March and April of the following year, the seeds will be treated before sowing. Because the seed coat is hard, in order to make the seeds germinate neatly and unearthed quickly, soak the seeds with 0.5% potassium permanganate cold water solution for 2 hours before sowing, rinse the seeds with clean water and soak the seeds in hot water about 80 ℃ for 30 seconds (the longest can not exceed 1min, otherwise affect the germination rate), and sow seeds after 24 hours. Using this method to promote germination, the germination rate can reach 80% MUE 90%, and the growth after emergence is robust and not easy to get sick.

3. Raising seedlings

The methods of raising seedlings are nutrition bowl and nursery.

The seedlings were raised in ① nutrition bowl. There are two kinds of commonly used nutritious soil: one is coke ash 60% 70%, garden soil 20% 30%, garbage or fence fertilizer 9.5%, calcium magnesium phosphate 0.5%, mix evenly; the other is 90% fertile topsoil, 7% plant ash, 1% bone powder, 2% rotten livestock fertilizer, mash and mix well. Sow 23 germinated seeds per cup, cover them with mud or fine soil 1cm, and sprinkle some pine needles if possible. The seeded nutrition cups were arranged into a border with 1cm width and variable length, and the soil was cultivated around the border to keep moisture, about 180000 / hm2, and germinated and sprouted one week after sowing.

Seedlings were raised in ② nursery. The nursery should choose places with leeward direction, deep soil layer, sandy soil or loam, and convenient drainage and irrigation. Loosen the soil and hoe the clods to make a seedbed with a width of 1m and a smooth surface in the east-west direction. Before sowing, first apply rotten manure and calcium magnesium phosphate fertilizer on the border, and then cover with a layer of fine garden soil. Use wide strip sowing or sowing, after sowing, cover with a layer of fine mud ash about 0.5cm thickness, and then cover rice straw, wet with water to keep the soil moist. Using the amount of seed, sowing 4560kg/hm2 with transplanting seedlings and sowing 3037.5kg/hm2 without transplanting seedlings. Within 7 days after sowing, water should be sprayed 12 times in sunny days to keep the seedbed moist. After the seedlings were unearthed, the mulch was gradually removed, the first true leaf was generally removed, all the mulch was removed, and the weeds were removed.

The seed method of albizzia tree seed is relatively simple, only need to do a good job of soaking seeds before sowing.
