What is the technical method of planting cypress trees?

Cypress bonsai cultivation skills, the method must be found correctly.

The growth environment of cypress trees:

Lighting:Cypress trees love light, but seedlings and young trees have a certain shade tolerance. It generally grows on the shady side of the mountain.

Temperature:Cypress trees are hardy and less resistant to wind.

Moisture:Cypress trees are drought tolerant and moisture-loving, but not flood-tolerant.

Soil:Cypress trees are barren tolerant and can grow on slightly acidic to slightly alkaline soils.

Planting management of cypress trees

The planting of cypress trees needs to focus on soil conditions, the choice of fertile and loose soil is the most suitable, and there is no strict requirement for acidity or alkaline, and it is also necessary to dig the specific consideration of the pit, according to the size of the soil ball of the cypress sapling to dig the pit preparation, but also pay attention to the depth, the depth of the pit is generally about 90 cm is more appropriate.

Pest and disease control of cypress

The diseases and pests of cypress are mainly Arborvitae caterpillars, wood-borers, etc., and the pests and diseases need to be captured manually in time, and the disease is serious and it is necessary to spray with appropriate pesticides, and the prevention of pests and diseases can be done by regularly loosening the soil and fertilizing the way to accelerate the rapid growth of cypress trees and enhance their disease resistance.

Cypress trees sometimes have yellowing, which is mainly caused by abiotic and abiotic factors caused by leaf blight (red leaves) disease and early yellowing, mainly due to the following reasons:

1. Insufficient soil moisture can not meet the needs of cypress growth and development, resulting in thin or wilted leaves and yellow tips, resulting in early defoliation. Or poor drainage, soil water, resulting in anaerobic respiration of roots for too long, accumulation of excessive alcohol, poisoning and rotten roots. or soil compaction, poor aeration, resulting in yellow leaves.

2. The planting is too dense, the ventilation and light transmission are poor, and the plants compete for fertilizer, water and shade, which affects photosynthesis and large respiratory consumption, resulting in yellowing of leaves and early defoliation.

3. Caused by improper field management. For example, the roots are injured when the seedlings are raised, the roots are nested when planting, and the animals bite the branches or artificially hurt the skin, resulting in yellow leaves. 1.The pathogenic fungus is mainly one species of Alternaria spp., which infects cypress trees and causes leaf blight.

4. Underground pests bite the bark of seedlings and are also easy to cause yellow leaves.

5. Yellowing and scorching of leaves caused by lack of fertilizer or unreasonable fertilization.

Cypress bonsai cultivation skills, the method must be found correctly.

1. Planting method: Planting cypress trees should choose seedlings with a height of less than meters, and then plant them in a fertile field, and insert wooden sticks to fix the main trunk after covering the soil. 2. Post-planting management:

One week after planting, water thoroughly, and remove the sticks after a month. 3. Pest control: regularly clean up the dead leaves and fallen leaves under the tree to avoid the breeding of pests and bacteria.

1. Planting method

To plant cypress trees, we should choose seedlings with a height of less than meters and healthy growth, and then dig a hole in a fertile and loose field with good drainage, plant the cypress seedlings in the soil hole, and then fill the hole with soil, bury the seedling root system deeply, and insert a wooden stick into the root to support the main trunk of the cypress tree in order to avoid lodging.

2. Post-planting management:

Just after planting, there is no need to water the cypress, wait for a week, you can water it once, so that the root system and the soil are fully in contact with each other, and in the later management, you only need to water after the soil is dry, and the wooden sticks inserted during planting should be removed after a month, which is conducive to the growth of the main trunk.

3. Pest control

Common pests and diseases of cypress trees are rotten to do arborvitae aphid, red spider, leaf blight, etc., resulting in the phenomenon of dead leaves and fallen leaves of the plant, poor growth, during the breeding period, it is necessary to regularly clean up the diseased leaves and dead leaves under the tree, destroy the breeding ground of bacteria and pests, and spray insecticides and fungicides in time after the disease, so that the cypress grows healthily.

Cypress is the general name of cypress plants, a kind of evergreen tree of the genus Arborvitae orientalis, widely distributed in China, from Inner Mongolia and Jilin in the north, to Guangdong and northern Guangxi in the south, the artificial cultivation range is several times throughout the country, it is an excellent landscaping tree species. So do you know what cypress trees are planted? Let's take a look.

How cypress trees are planted

1. Forest land selection: cypress has low soil requirements, and can grow normally in various types of organic rock or soil, but cypress is not resistant to water and humidity, and has little wind resistance, so it is not suitable for planting in low-lying land, mountain areas with wind outlets, and large wind speeds.

2. Afforestation density: cypress grows slowly in the first 100 years, the crown is narrow, the root distribution is also shallow, and the canopy closure time is very long, so the initial planting density is 5000 6000 hectares, and the later thinning is carried out according to the canopy closure.

3. Mixed tree species: cypress grows slowly, the canopy is narrow, and weeds are easy to breed in the woodland, in order to inhibit the growth of weeds, in the process of cypress afforestation, it is often mixed with tree species such as Pinus tabuliformis, Acer truncatum truncatum and Robinia pseudoacacia, or mixed with shrub species such as Acacia purpurea, sea buckthorn and Hu Zhizi.

4. Meticulous land preparation: cypress afforestation usually chooses arid and barren mountainous land, so the land preparation methods usually include fish scale pit land preparation, horizontal ditch land preparation, and horizontal step land preparation, and land preparation needs to be advanced for one season.

5. Afforestation technology: cypress afforestation can be selected in spring, rainy season or autumn, cold and dry in winter is not suitable for afforestation, commonly used sowing afforestation, seedling afforestation, container seedling afforestation, can also use large seedling afforestation, but large seedling afforestation needs to be transplanted many times.

6. Management and protection of young forests: Artificial weeding and chemical weeding can be used for young cypress forests, and soil and grass can be covered and whitened to prevent cold during wintering. At the same time, due to the slow growth of cypress trees and the narrow canopy, forest grain intercropping can be used to improve the land use value after planting.

What are the types of cypresses

1. Arborvitae: Arborvitae orientalis is a special tree species in China, light-loving, slightly shade-tolerant when young, strong adaptability, not strict requirements for soil, can grow in acidic, neutral, calcareous and light saline-alkali soils, drought resistance and barrenness, strong germination ability, medium cold resistance, and weak wind resistance.

2. Juniper: Juniper is a unique tree species in our country, likes cold and cool climate, strong cold resistance, does not have strict requirements for soil, can grow in arid sandy land, sunny slopes and rock crevices, and is often used for garden purposes, wood can be used as furniture materials, and roots can be used as medicine.

3. Cypress: Cypress is an excellent landscaping tree species, light-loving, seedlings and young trees have a certain shade tolerance, more cold-resistant, poor wind resistance, drought resistance, barrenness-resistant, moisture-loving, but not flood-resistant, can grow on slightly acidic to slightly alkaline soil.

4. Cypress: Cypress is an evergreen tree, cold-resistant, likes cool and humid climate, shallow rooting, does not have strict requirements for soil, and is often used for garden purposes, such as landscape trees, groves, hedges, basic planting, landscape forests, sanitary shelter forests (health tree species), etc.

5. Longbai: Longbai likes the sun, slightly tolerant to shade, likes warm and humid environment, cold-resistant, drought-resistant, avoids stagnant water, has strong adaptability to soil pH, strong resistance to sulfur oxide and chlorine, but has poor resistance to smoke and dust, and has high ornamental value, and is widely cultivated in various parts of China.

Select germination: Select full-grained, disease-free and fully mature cypress seeds, then sterilize and germinate them. Planted in the soil:

Spread the slightly white cypress seeds evenly on the surface of the soil, cover with soil, and water to moisturize. Precautions: When cypress seeds emerge, it is necessary to apply 1-2 times of rotted farm fertilizer.

1. Seed selection and germination

Before planting cypress, you need to select full-pronged, disease-free and fully mature seeds, and then soak them in potassium permanganate solution for 2 hours to play the role of disinfection and sterilization, remove and drain them, and then soak them in warm water at 45 degrees for germination treatment.

2. Plant into the soil

Choose a flat terrain, good drainage, loose and fertile sandy loam soil for planting, after fertilizing the soil deeply, evenly spread the slightly white cypress seeds on the soil surface, and cover a layer of fine soil, watering to keep the soil moist, and finally cover a layer of plastic film or straw to promote the rapid germination of seeds.

3. Precautions

In the process of planting cypress, it is necessary to choose the appropriate planting time according to the local climate and environment, generally in the northeast region in mid to late April, and the planting time in North China is mostly in mid to late March, in addition, when the cypress seeds emerge, it is necessary to apply 1-2 times of urea or rotten farm fertilizer.
