How to choose albizzia seeds? What are the methods of raising seedlings?

Albizzia is a highly ornamental plant, although it is a tree, it can also be potted. Spring to autumn is the viewing period, with emerald green leaves, strange flowers, beautiful and handsome. The choice of environment is not high, so it can be planted in the south of the Yellow River in China. So how to choose the seeds of Acacia? What are the methods of raising seedlings? Next, let's have a look with the editor.

First, how to choose the seeds of Acacia?

Albizia is often sown and propagated, and the seeds are collected from September to October. The fruit color changes from green to brown and the seeds can be picked after hardening. When collecting seeds, you should choose pods with full seeds and no diseases and insect pests, dry and hide them in a dry and ventilated place to prevent mildew.

The seeds should be treated from March to April in the following year (the next year after seed collection) before sowing. As the seed coat is hard, in order to make the seeds germinate neatly and unearthed quickly, soak the seeds in 0.5% potassium permanganate cold water solution for 2 hours 2 weeks before sowing, rinse the seeds with clean water and soak the seeds in hot water about 80 ℃ for 30 seconds (the longest cannot exceed 1 minute, otherwise affect the germination rate), and sow seeds 24 hours later. By using this method, the germination rate can reach 80%-90%, and it is not easy to grow strong and not easy to get sick after emergence.

What are the seedling raising methods of Albizia paniculata?

1. Make a bed by preparing the ground.

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. The nursery ground should be flat and fine, with sufficient fertilizer, with a ridge distance of 60 cm and a groove depth of 15 cm.

2. Sowing and raising seedlings

The ditching strip sowing method was used to sow seeds from March to April with a sowing area of about 10 cm and a seed consumption of 4 to 5 kg per 667 square meters. After sowing, cover with a layer of fine plaster about 0.5cm thick, then cover with straw and wet with water to keep the soil moist. Using the amount of seed, sowing 45~60kg/hm2 with transplanting seedlings and sowing 30~37.5kg/hm2 without transplanting seedlings.

3. Seedling stage management

To keep the soil moist after sowing, if the soil is too dry to affect seedling emergence, you can irrigate the wet soil in the furrow, and avoid watering over the ridge surface, so as not to harden the soil and affect seedling emergence.

Within 7 days after sowing, spray water twice on a sunny day 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.

4. The seedlings are fixed

After the seedlings grow the second true leaf and time seedlings, pull out the sick and weak plants and over-dense plants, the distance between the plants is 10 cm, and the seedlings should be watered in time.

The above is the introduction of Acacia, which is light-loving, drought-resistant, water-intolerant, fast-growing, adaptable and lax in soil requirements. Seed acacia is not difficult. If you want to plant a good acacia, you must choose a good seed and raise seedlings.
