Step 4 trim

Bonsai cotinus coggygria often grows many new branches. In order to keep a good appearance, you should trim it frequently. Pruning should be decided according to the shape of the tree. Generally, dead branches, parallel branches and cross branches that affect the appearance should be cut off in time.

5, repair the roots

When turning over the pots of Cotinus coggygria bonsai, the roots should be trimmed properly. For the roots that grow very densely, we should prune more and cut off the redundant old roots. After pruning, loosen the soil and fertilize the roots properly, which can promote the new roots to grow better.

Seedling raising techniques of cotinus coggygria

(1) Seeding and seedling raising: The young cotinus coggygria forest begins to bear fruit in 3 years, and strong-aged mother trees are selected for seed collection. Seeds were treated by mixed sand storage and warm water soaking. Store the mixed sand in the leeward and sunny place to dig a hole. Wet sand and seeds are mixed and poured into the pit, covered with wet sand, and grass is erected around the pit for ventilation. Soak seeds in warm water 20 ~ 30 days before sowing to accelerate germination. Soak the seeds in warm water at 45℃ for 24 hours, take them out and spread them in sunny places, cover them with straw curtains and wet sacks to accelerate germination, and sow when 30% of the seeds turn white.

(2) Cotinus coggygria can be sown in spring and autumn, and the seeds sown in spring are stored in sand from June 5438+February to March of the following year. Sow in low bed, covering 1 ~ 1. 5cm. Emerge 7 ~ 10 days after sowing, and transplant between seedlings when the height of seedlings is greater than 10cm. Seedlings grow fast, shoot fast and lodging easily, so they can be pruned properly. Apply fertilizer and water for 2 ~ 3 times at seedling stage, loosen soil and weed for 3 ~ 4 times, and pay attention to prevent collapse and drainage.

Cultivation techniques of cotinus coggygria

Cotinus coggygria has strong adaptability and can be planted under various site conditions, but low wetland and saline-alkali land are not suitable for afforestation. It can be used not only as a pioneer tree species for afforestation in barren hills, but also as a protective tree species, especially as an ornamental tree species in scenic spots.

(1) Afforestation technology: Cotinus coggygria is usually planted in March-April in spring. When planting, the excessive lateral roots should be trimmed properly, the root width should be kept at 30 ~ 40 cm, and the overground parts can be cut off appropriately. Shelterbelt can adopt the plant spacing of 1x2m. The spacing between the scenic forest and the parent forest is 2×3m or 3×4m. The plant spacing of the mixed forest is 2×3m, and it is banded mixed, that is, 3 ~ 4 rows of cotinus coggygria are mixed with 2 ~ 3 rows of other tree species.

(2) Young forest tending: During the young forest of Cotinus coggygria, it is necessary to loosen the soil and expand the hole, and strengthen water storage and moisture conservation. Different tree shape can be maintained accord to different cultivation purposes. The lower lateral branches of the scenic forest can be trimmed appropriately to promote the growth of the trunk and form a complete crown. The water conservation forest for soil and water conservation can be leveled in 3 ~ 5 years after afforestation, and the stubble height after leveling is flush with the ground, forming dense branches and leaves to cover the ground.

Water and fertilizer management should be done well in the cultivation period of cotinus coggygria bonsai. Cotinus coggygria is very afraid of waterlogging. Usually, just water the soil and keep it slightly wet. Fertilization should also follow this principle. The growth period is mainly compound fertilizer, and the lignification period is mainly phosphate fertilizer.

4, plastic pruning

Cotinus coggygria bonsai needs pruning to create a perfect tree shape with strong germination. It should be pruned in spring and tied with branches at the same time. In the later growth process, long branches, over-dense branches, cross branches and diseases and pests are mainly cut off.
