How to plant oak and its planting methods and matters needing attention

Oak is a general term for Fagaceae plants, which contains many varieties, not specifically. The oak is the largest flowering plant in the world. It has a long life span and can be as old as 400 years old. Acorns are nuts and are good food for squirrels. Many people want to plant an oak tree, so how to plant an oak tree? What is there to pay attention to?

How to plant oak trees

1. Oak likes sandy loam or slightly acidic soil with good drainage, which is resistant to environmental pollution and has strong adaptability to barren, dry, acidic or alkaline soil.

2. The oak tree grows at a moderate rate and grows 60 centimeters a year on moist, well-drained soil.

3. Oak trees are mainly propagated by seeds and planted in spring

Oak planting methods and matters needing attention

1. Seed collection of acorn trees

① usually begins to bear fruit at the age of 20 years, mainly by sowing and reproduction, and the amount of seed is large. Flowering in May and fruiting in September or October.

When the ② fruit falls off naturally or shakes, the tree will fall and pick up seeds from the ground. The germination rate of seedling seeds with 1000-grain weight of 3000-4500 grams is high.

Seedling seeds sown in spring in ③ need to be stored in wet sand. That is, after the seedling seeds are collected, dry in a cool place, do not expose to the sun, and then collect the pure seedling seeds, store them in layers with 3 times wet sand, and sow them in the next spring.

2. Acorn tree sowing

① can be sown in autumn, winter and spring. Sowing in autumn and winter is carried out from November to December, and the seeds are generally sown with picking after maturity.

② sowing in autumn and winter can be used in areas where frost is not serious, and it accords with the characteristics of oak trees and reduces storage. It sprouts and emerges early in the next spring, and the survival rate is higher than that of spring sowing.

Spring sowing in ③ should be early to avoid germination and mildew of stored seedlings. Seedling seeds are often damaged by elephant trunk and can be soaked in 551 warm water for 10 minutes before sowing. Quercus variabilis is a mycorrhizal tree species, which needs to be mixed with mycelia. Strip sowing was used with row spacing of 20 cm and seed spacing of 10 cm.

The sowing rate of ④ is 150kg-200kg per 667m2. Seedling seeds should be placed horizontally when sowing, which is beneficial to seedling emergence and rooting. After sowing, cover soil is 3 cm, and it can also be covered with fungus soil to benefit mycorrhizal development. The thickness of the covered soil should be the same, otherwise the seedlings will not emerge neatly.

3. Acorn tree growth

① seeding seedling management-emergence about one month after sowing. The young roots are already deep in the soil by the time the seedlings become a scholar.

In order to promote the formation of lateral roots, ② cut off the main roots of seedlings with a shovel one month after emergence, and watered them in time after root cutting. The seedlings that cut off the main roots tend to grow slowly for a while.

In the fast-growing period of ③, both height growth and thick growth are faster, so fertilizer and water management should be strengthened. Quercus variabilis is a full-period growth type, and the rough growth does not end until the beginning of November. The height of one-year-old seedlings can reach 40-60 cm. The transplantation was carried out from defoliation in autumn to bud germination in spring.

When transplanting ④, pay attention to the protection of root system and bring more lateral roots as much as possible. Large seedling cultivation of Quercus variabilis is a strong top dominant tree species, in order to promote the shape of tall and straight, timely pruning, the incision should be smooth, do not hurt the bark, do not leave stakes.

Propagation method of oak tree

1. Oak trees are propagated mainly by seeds.

2. Cultivation period: spring

3. Germination period: seeds propagate, seeds can germinate without treatment, but the germination time is longer. If it is treated at 5 degrees Celsius for 30 to 45 days before sowing, the germination rate can be increased and can be germinated in 2-3 weeks. When the sowing rate is 100-250 kg per 667 square meters (1 mu), the seeds should be placed horizontally to facilitate the radicle to grow downward. The thickness of the covered soil is 2-5 cm, and the seedling height can reach 20-40 cm in the same year.

Can oak trees make potted plants?

You can plant plants.

Oak trees are widely cultivated in various parts of our country. Sex likes a warm, humid, sunny environment, but also slightly shade-resistant, not cold-resistant. It is required to have fertile and loose soil and grow well in neutral or acidic soil. When potted, it is appropriate to use rotten leaf soil, grass ash soil plus about 1 to 4 river sand and a small amount of base fertilizer to form culture soil. Usually keep the soil moist and apply dilute liquid fertilizer every 15-20 days.

Oaks are deciduous or evergreen trees with a height of 25 to 30 meters or more. Strong resistance to stress, resistance to drying, high temperature and water humidity. It has a long life, and the study found that a dwarf Rupa oak in California has survived for at least 13000 years and may be the oldest known living creature in the world.
