Acacia culture

Acacia is a common potted ornamental plant, what problems should be paid attention to in breeding acacia? Let's take a look at it together.

Acacia is a mimosa and belongs to the genus Acacia. In recent years, Bauhinia and Bauhinia are more introduced. Use wide strip sowing or sowing, after sowing, cover with a layer of fine mud ash about 0.5 square meters thick, then cover rice straw, wet with water, and keep the soil moist. If the seedling height is more than 15 cm, the seedlings should be moved in cloudy or drizzle days, some branches and leaves should be cut off properly, and the plant should be planted in the prepared bed according to the row spacing of 10 × 30 cm.

Main points of cultivation of Acacia:

(1) sowing

Spring sowing from March to April and autumn sowing from late September to mid-October. Acacia seeds are solid and the seed coat is thick waxy, so soak the seeds with 60 ℃ 80 mol hot water before sowing, cool naturally during the waiting period, change once a day, take them out on the third day, mix with wet sand, pile up warm places, cover rice straw, sow seeds after 7 days of moisturization, and emerge after 5 days.

(2) raising seedlings

The methods of raising seedlings are nutrition bowl and nursery.

Nutrition bowl seedling: there are two kinds of commonly used nutrient soil, one is coke mud ash 60%, garden soil 20%, garbage or fence fertilizer 9.5%, calcium magnesium phosphate 0.5%, mixed evenly. The other is 90% of fertile topsoil, 7% of plant ash, 1% of bone powder, 2% of rotten animal fertilizer, mashed and mixed well. Sow 3 seeds per cup after accelerating germination, cover them with some mud or fine soil for 1 cm, and sprinkle some pine needles if possible. The seeded nutrition cups are arranged into beds with a width of 1 meter and varying lengths, and the soil around the beds is as high as the cups to maintain moisture. The row is about 12000 per mu. It will sprout and sprout a week after sowing. Nursery nursery: the nursery should choose leeward to the sun, the soil layer is deep sandy soil or loam, drainage irrigation is convenient. Loosen the soil and hoe the clods to make a seedbed with a flat surface of 1 meter wide 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 0.5 square meters thick, then cover rice straw, wet with water, and keep the soil moist. With the amount of seed, the need to transplant seedlings per mu sowing 3 Mu 4 kg. Do not move seedlings per mu sowing 2 Mu 2.5 kg. Within 7-days after sowing, spray water once or twice on a sunny day to keep the seedbed moist. After the seedlings were unearthed, the mulch was removed gradually, the first true leaf was generally removed, all the mulch was removed, and the weeds were removed.

(3) Management

After the emergence of Acacia acacia seedlings, when the seedling height was 3 Mel 5 cm, thin mature human feces and urine or chemical fertilizer were applied once to promote the growth of seedlings. If the seedling height is more than 15 cm, the seedlings should be moved in cloudy or drizzle days, some branches and leaves should be cut off properly, and the plant should be planted in the prepared bed according to the row spacing of 10 × 30 cm. If there is a sunny day after transplanting, it should be watered and shaded to help the roots of the seedlings survive. It is appropriate to transplant acacia seedlings in spring, which requires digging, planting and watering. As the trunk of Acacia seedlings is slender, transplanting should be careful and careful, pay attention to protect the root system. After planting, it should be watered in time, and then watered thoroughly. Apply enough base fertilizer at the end of autumn to facilitate growth and luxuriant flowers and leaves in the coming year.

The trunk of Acacia seedlings is often tilted not straight because the branches are too low. In order to improve the ornamental value, make the trunk straight and have appropriate branching points, seedlings can be reasonably close-planted, and pay attention to pruning lateral branches. For annual weak seedlings or stem sloping albizzia, one strong bud can be left when it germinates in the early spring of the following year, and it can be cut off to make it germinate into a sturdy and straight trunk.

The flower words of Acacia: fleeting happiness

Acacia, also known as nocturnal flowers, news flowers, deciduous upright shrubs, dignified and beautiful trees, spring leaves green, interesting, round crown, showing a heroic posture in the wind.
