Ecological classification: woody plants >; evergreen tree

Ornamental classification: forest trees

Height range: 8 meters

Morphological characteristics: the crown column looks like a dragon, and the lateral branches are slightly spirochete.

Growth habit: masculine, not cold-resistant, resistant to harmful gases, strong dust retention, and resistant to pruning.

Propagation and cultivation: Propagation usually adopts cutting and grafting. Cutting is more suitable in spring, when the temperature is 24℃ ~.

When cutting at 30℃, the top of the mother plant with a length of about 65438±0.5cm should be cut off, and the incision should be soaked in 500ppm indoleacetic acid solution for 65438 0 minutes. The cutting substrate can be vermiculite, pure river sand, peat soil or soil in which peat soil and river sand are mixed evenly. The cutting container can be a seedling pot or a seedling box. Put it in a cool shed or plastic shed, water it, spray it regularly every day, keep the relative humidity above 80%, ventilate it in time, and take root in about 60 days.

Longbai also often uses abdominal grafting to raise seedlings. Using seedlings of 3-year-old Sabina vulgaris as rootstocks and branches of 2-year-old Sabina vulgaris as scions should be operated in April, and the crown of rootstocks should be cut off in April of the following year after grafting, and those without grafting can be replanted.

Landscape uses: shade trees in the courtyard, cypress trees in the garden.

Longbai

Scientific name: Sabina vulgaris. kaizuka

Family and genus: Cupressaceae, Sabina.

Alias: Sabina vulgaris, Sabina vulgaris

Originated in southeast China, North China, Japan, North Korea and other places, and cultivated in cities such as southern North China and East China.

Ye Quan, resume. Kaizuka Aurea of the same genus has scaly leaves and yellow dendritic leaves. Resume. Recumbent grass has no upright trunk, and the plants spread out in situ, mostly with phosphorus leaves.

Habit:

Sabina vulgaris is a cultivated variety of Sabina vulgaris. Evergreen tree, 8 meters high, with straight trunk, narrow cylindrical shape and twisted branchlets, hence the name. Branchlets are dense, leaves are dense, all scales, young leaves are yellow-green, and old leaves are emerald green. The cones are blue-green, and the fruit surface is slightly white.

Longbai likes deep and fertile soil and requires good drainage, so wet waterlogging is strictly prohibited, otherwise it will cause yellow leaves and poor growth. It grows slowly when it is young and grows faster after 3-4 years. When the trunk is 3 meters high, its growth is weakened by Zhejiang.

Longbo likes the sun. Where the drainage is good and the soil layer is deep, it grows well. Strong drought tolerance, as long as the rhizosphere or seedbed is covered in summer and autumn, it is generally not watered to fight drought and rarely dies, but in order to promote growth, the annual growth can be increased by 50 cm by adding fertilizer and water frequently. The main branch of the cypress is very malleable, but in the south of the Yangtze River, it does not spread outward but rotates upward around the main branch, and the side branches are closely arranged. The whole tree is supported by Wan Ru Shuanglong, so the branches below should be properly preserved, and cannot be cut off or damaged at will, otherwise hanging seedlings will be formed, which will do great harm to the appearance, so it is generally not pruned and allowed to grow naturally.

Some cypress trees not only naturally grow into cones, but also roll up animal images such as dragons, horses, lions and elephants. Some of them are pruned into spheres, drums and hemispheres and planted in single rows or groups in the garden. Some species are planted in hedgerows, and trimmed into straight ridges after shaping, which can show their low, plump, meticulous and fine. The side branches of cypress are winding, twisted and dry, unique and of high ornamental value. Widely cultivated in all parts of China.

Pests and diseases:

There are few diseases in cypress trees. In addition to the above-mentioned pear scab, purple feather disease is also prone to occur when the substrate of cutting seedbed is unclean or reused, which can be controlled according to the above methods. The marsupial moth is a common pest, so it should be sprayed with 1000 times 98% crystal trichlorfon when the larvae have not spread in early June.

Cultivation management:

Dragon and cypress are used to asexual reproduction, and the methods include docking, branch grafting, cutting and layering. , each has its own advantages, which are described as follows:

1, the grafting survival rate is high and the seedlings grow fast. The disadvantage is that the number of breeding is limited, and the procedures and management are more troublesome. Because the mother tree is tall, it is even more inconvenient to operate, but this method can still be propagated in small quantities.

Sabina vulgaris, Sabina vulgaris, Platycladus orientalis and Platycladus orientalis can be used as rootstocks. It can be performed in 3-4 months, and it can be cut off and transplanted from the mother when it is completely healed in August-September. For specific operation, please refer to the docking chapter in the book of seedlings and flowers.

2. Grafting in early spring: In early spring, in February, 2-year-old Platycladus orientalis was used as rootstock, and 1-2-year-old branches with a length of 5- 10 cm were selected as scions. Take off the 2-3 cm lower needle, make a straight cut with a length of 2-3 cm, and make a diagonal cut on the reverse side with a length of 2-3 cm. Rootstock can be cut from the grafting point, and then directly from one side of the cross section, 2-3 cm long, pay attention to the xylem. Then insert the cut scion into the rootstock, with the cambered layers on one side aligned with each other, and then tie the joint firmly with plastic film. In order to make the scion die without losing water before survival, a small plastic bag can be put on the scion. About 2 months later, the terminal bud of the wind scion germinated, which proved that the wound had healed well, and the bagging could be removed for normal management. In addition, the skin can be torn and spliced during the growing period. The grafting survival rate of this method is also very high.

Breeding method:

Longbai is a precious garden tree with a cylindrical crown, which looks like a dragon and a fixed tower. It is suitable for planting around Gaoxia Square or for potted plants. It has adsorption function and dust removal effect on a variety of harmful gases.

Although cypress can bear seeds, it is not easy to germinate. The propagation methods are mostly cutting and grafting.

The grafting propagation of Sabina vulgaris is suitable for mid-February to early March in spring and late September to early June in autumn. Two-year-old Platycladus orientalis is used as the rootstock, and the grafting method is as follows: (1) Ground grafting: the aboveground part of the rootstock should be kept, the soil of the rhizome part should be removed by 3-5 cm, and the rootstock should be cut to about half depth. The scion is selected from the middle section of biennial branches, about 8 cm long, and the needles at the base are removed by one third. Cut one side to 1.5-2 cm, and the other side is about 0.6 cm. Insert the scion into the incision of the rootstock, align the cambium of the two branches, tie it tightly with plastic film, cover it with soil for 3-5 cm, cover it with grass to prevent drought, and build a shed to cover the curtain for temporary shade. (2) Digging: After digging the roots, properly trim the roots and branches. Digging method is the same as ground grafting, but it should be planted in time after grafting, and the top height of soil should be 3 cm. After grafting, it is slow from the beginning of healing to survival, and it begins to heal in May after grafting in spring, so it is necessary to gradually cut off the branches and leaves of the rootstock. After that, in addition to proper shading, preventing drought and strong wind from blowing, and maintaining a certain humidity, rain water should be prevented from invading in the next half month, and the general survival rate can reach more than 75%.
