Planting technique of Platycladus orientalis

Cypress is a kind of cypress, a specialty of China, which is distributed all over the country except Qinghai and *. It has a long life. It is often a sunny slope afforestation tree species, and it is also a common garden greening tree species. Wood can be used for construction, furniture and other materials, leaves and branches can be used as medicine. Can converge hemostasis, diuresis and stomach, detoxification and blood stasis, seeds have the effect of calming the mind and nourishing strength. Let's take a look at Platycladus orientalis planting technology.

Planting value of Platycladus orientalis

Platycladus orientalis is a precious timber tree species, its wood is moderate in hardness, fragrance, corrosion resistance and dense texture, so it is a good material for shipbuilding houses and docks. at the same time, it is widely used in buildings, bridges, electric poles, pillars, sleepers, and furniture. It can be used as carving cabinetwork. At the same time, beautiful trees, luxuriant branches, evergreen four seasons, fragrance, few insect pests, strong adaptability, is a common green tree species, often planted in temples, mausoleums. In addition, the seeds of Platycladus orientalis can be used as medicine and oil, and can also be used to make spices.

Planting environment of Platycladus orientalis

1. Growth habits: Platycladus orientalis likes light, slightly tolerant to shade when young, strong adaptability, loose requirements for soil, can grow in acid, neutral, calcareous and light saline-alkali soil, drought and barren, strong sprouting ability, medium cold resistance, strong sunlight resistance, high temperature and shallow roots, those below 400 meters above sea level grow well, and the wind resistance is weak. Shallow roots, but developed lateral roots, strong sprouting, pruning resistance, long life, resistance to smoke and dust, resistance to sulfur dioxide, hydrogen chloride and other harmful gases.

2. Origin distribution: Platycladus orientalis is distributed in Liaoning, Sichuan, Ningxia, Hubei, Henan, Shaanxi, Qinghai, Gansu, Inner Mongolia, Yunnan, Shandong, Hebei, Beijing, Tianjin, Shanxi and other places. Jilin Province is distributed below 250m above sea level, Huashan is distributed at an altitude of 1000m to 1200m, Shaanxi and Yunnan are distributed at an altitude of about 1500 and 2600 meters respectively.

Planting technique of Platycladus orientalis

1. Woodland selection: Platycladus orientalis is not strict on soil and can grow normally in various types of machine rock or soil. However, Platycladus orientalis is not resistant to water and humidity, and its wind resistance is small, so it is not suitable to be planted in low-lying land, mountain area and high wind speed.

2. Planting density: Platycladus orientalis grew slowly in the first 100 years, the crown was narrow, the root distribution was shallow, and the closure time was very long. Therefore, in order to promote its canopy closure, the initial planting density is 5000 to 6000 plants per hectare, and thinning is carried out in the later stage according to the canopy closure.

3. Mixed tree species: due to the slow growth and narrow crown of Platycladus orientalis, it is easy to breed weeds in the woodland. in order to restrain the growth of weeds, Platycladus orientalis is often mixed with Pinus tabulaeformis, Acer truncatum, Robinia pseudoacacia and other tree species in the process of afforestation. Or mixed with shrubs such as Amorpha, Hippophae rhamnoides, Elaeagnus angustifolia.

4. Meticulous soil preparation: in the process of Platycladus orientalis afforestation, careful soil preparation is an important guarantee to improve the survival rate and preservation rate of afforestation. Platycladus orientalis usually chooses arid and barren mountain areas for afforestation, so the methods of soil preparation are usually fish scale pit, horizontal ditch and horizontal step, and it is better to prepare soil one season in advance.

5, afforestation technology: Platycladus orientalis afforestation can choose spring, rainy season or autumn, cold, dry and cold winter is not suitable for afforestation. Afforestation seedlings are usually one-to three-year-old bare-root seedlings, one-to two-year-old container seedlings, and two-to three-year-old transplanted seedlings. Afforestation methods are commonly used in sowing afforestation, planting seedlings and container seedlings, and large seedlings can also be used for afforestation, but large seedlings need to be transplanted many times to cultivate their well-developed roots.

6. young forest management and protection: first, loosening the soil and weeding, manual weeding and chemical weeding can be used. Second, overwintering against cold, can be covered with soil and grass against cold, painted white against cold. Third, forest-grain intercropping, Platycladus orientalis because of slow growth, narrow crown, forest-grain intercropping can be planted to improve the value of land use.
