How to manage the small tung planted this year

Water it regularly to bring it to life and sprout new shoots.

The scientific name is plane tree.

Shaping and pruning techniques:

1. Tree selection. Plane trees have straight trunks with spread branches, usually with a broad, naturally shaped canopy. When making street trees, the shaping method is generally cup-shaped, if there is no overhead line above, it can also be used in the open shape, and when it is used as a shade tree, it is mainly natural straight trunk shape or multi-main branch shape.

2. Shaping and pruning. In the winter of the second year, the tips are cut off at 3 points at the height of the tree, and the side branches on the main trunk below the branch point are cut off. In the third year, after the seedlings germinate, select 3 5 thick branches near the branches as the main branches, and cut the rest in batches.

In winter, leave 50 80cm stub on the main branch, leave the cut bud on the side, try to make it on the same horizontal plane, after germination in the next spring, each selects and leaves 2 3-level lateral branches to grow obliquely, that is, the shape of "three strands, six forks and twelve branches", after 3 4 years of cultivation, the diameter at breast height is 7 8cm, and has begun to take shape in a cup-shaped crown type, which meets the standards of street trees and can be out of the nursery. After planting, the cup-shaped street tree should be pruned for 4 5 years in the same way as the seedling stage, until the canopy has 4 5 level side branches. After the annual dormant period to the current year's branches.

There is basically no need to prune in 3 years, as long as the tip can be guaranteed to be straight. Seedlings after 3 years can be properly pruned with branches below the meter.

1. Habit: Sycamore likes light, likes well-drained, moist and deep acidic or neutral and calcareous soil; Resistant to severe cold, drought, barrenness, avoid waterlogged depressions, saline-alkali land planting; It is not tolerant to waterlogging and grass shortage, and the bark is not resistant to scorching sun. The straight roots of the sycamore are stout, the life span is long, and it can live for more than 100 years; Budding is weak, budding late in spring, but leaves fall early in autumn.

2. Planting: It is often propagated in the form of seeding, but cuttings and root propagation can also be carried out.

Before sowing, the seeds should be treated, first soaked in 60 80 warm water to promote germination (note that the water should be stirred while filling water), until the water temperature drops to room temperature, and then washed with water, after fishing, the mixed wet sand is stacked in the leeward and sunny place, the thickness is not more than 30cm, and the wet sack piece or straw curtain is covered, and it is necessary to turn the water frequently. When the seeds are 1 3 white, they can be sown in phases and batches.

The sowing time can be in autumn or spring. But often in early April spring sowing, sowing 250kg 300kg per mu, sowing width 25cm 30cm, covering soil thickness, 27 days after the emergence of seedlings.

3. Management: Usually planted in spring, before planting, water the bottom of the pit and apply sufficient base fertilizer, and plant according to the row spacing. In order to improve the survival rate, it is necessary to be practical and timely watering after planting.

Before the arrival of winter, the main trunk of the young tree should be wrapped with straw to protect against the cold, and watered and fertilized once before winter and early spring respectively (mainly based on base fertilizer, supplemented by top dressing). Apply fertilizer 2 times and 3 times a year, use phosphate fertilizer as basal fertilizer, mainly fast-acting nitrogen fertilizer, and apply potassium fertilizer at the same time.

Pests and diseases, while killing pests and diseases, we should pay attention to the protection and use of insect natural enemies, such as ladybugs, parasitic wasps, lacewings, etc. When pests appear in the nursery, the larvae and pupae in the leaf curls can also be pinched to death directly by hand, and the pine borer can also be injected in the pit of the trunk, and the diseased fallen leaves can be removed and burned in time.

Habits: The French plane tree is characterized by the fact that when the leaves fall in autumn, the leaves on the plane tree are not all golden.

Winter pruning has an important impact on the growth and tree shape of the tree, if not timely and reasonable winter pruning, it will lead to the disorganized tree shape, the main branches are long, the leaves are few or low clusters, which greatly reduces its ornamental value and shading effect. Timely and reasonable pruning can make the tree majestic and upright, straight and graceful in a short period of time, the branches are dense and compact, the side branches are many and symmetrical, the leaves are thick and green, and the natural immunity of the tree body is enhanced. The winter pruning of the tree can be carried out in autumn and winter before the leaves fall off, the soil freezes, and the tree is dormant until the sap flows in the spring of the following year.

For newly planted young trees, when the stem is up to high, it is called "fixed stem". Pruning can be based on the overall view of the whole tree and the determination of the future cultivation direction, first cut the upright branches, drooping branches, then prune the diseased branches, cross branches, weak branches, inward branches and branches that affect transportation facilities, and finally leave 3 4 strong main branches. The main branch should be conducive to future shaping, with strong growth and moderate opening angle.

After selecting the main branch, it should be shortened at 30 40cm near the base, the cut should be smooth and not hurt the bark, and the wound protector should be applied at the cut to avoid pests and diseases and water transpiration. Smoothing the wound also promotes the formation of callus, which aids wound healing and prevents bacterial infection. The wound care agent can be waxed, white-coated Jining tung agent, tung oil or paint.

Every 3 to 4 years after the growth of young trees, a large pruning of the tree body is carried out in winter. Generally, the 3 to 4 main branches that are retained for the first time can be basically unchanged, and then 1 2 strong branches are retained on each main branch, and the length of 20 30cm can be left in the short truncation. The side branches on the twigs can be left according to the specific situation, such as when the communication line next to the tree is not high, only the 3 4 stub main branches left when the first time is set to dry can also be retained, so that the height of the whole tree can be reduced, and the light transmittance of the branches and leaves is increased at the same time, which does not affect its growth, and also protects the tree shape well.

Hehe, I'm from the seedling base of Fatong, let me tell you, it's very simple. Mess him first, remove the hair inside, soak it in warm water for 24 hours, and then wrap it in a damp cloth and put it on the windowsill to keep the humidity and temperature. Hehe, it can germinate in 3-5 days.
