Culture methods and matters needing attention of bamboo and cypress

Bamboo and cypress is a second-class protected plant in China, also known as coconut, Luohanchai and so on. it is a tree of the genus Bamboo and Cypress of the family Pine, with green and glossy leaves, rich crown and beautiful tree shape. it has been developed in recent years as an excellent scenic tree widely used in gardens, residential areas, streets and other areas for greening. Let's take a look at the breeding methods and matters needing attention of bamboo and cypress.

Culture value of Bamboo and Cypress

1. Ornamental value: the branches and leaves of bamboo and cypress are green and shiny, the crown is rich, and the tree shape is beautiful. it is not only a good shade tree in the south and a street tree in the garden, but also an excellent tree species for greening around urban and rural areas. it can be planted in parks, gardens, residential areas, streets and other areas, or mixed with other evergreen deciduous trees.

2. Home decoration: bamboo and cypress can be mixed with other needles and broad-leaved trees in the warm part of the green space of the park, and can also be planted or planted in the shelter of tall buildings, and it is also appropriate to plant and watch in pots. The branches and leaves of bamboo and cypress are green and glossy, the crown is rich, the tree shape is beautiful, the leaves are thick and shady, and it is easy to breed, so it is very suitable for breeding indoors for home decoration.

3. Economic value: bamboo and cypress sapwood is yellowish white, heartwood is dark, straight texture, fine structure, moderate hardness, specific gravity 0.47-0.53, easy to process, durable, for excellent construction, shipbuilding, furniture, appliances and craft materials. The leaves of bamboo and cypress are shaped like bamboo, the crown is beautiful and rich, it is a beautiful ornamental tree species and woody oil tree species, the seeds are oily and can be eaten.

4. Medicinal value: bamboo and cypress not only has unique ornamental value, but also has certain medicinal value. Bamboo and cypress has the effect of hemostasis and bone grafting. Bamboo and cypress with leaves as medicine, can be collected throughout the year, washed, fresh or sun-dried, with the effect of hemostasis, bone grafting, appropriate amount of external use, tamping of fresh products or dry products can treat bleeding, fractures and so on.

Propagation methods of Bamboo and Cypress

1. Sowing: bamboo and cypress seeds can be sowed with picking in the greenhouse or sown in the open field in spring. After sowing, the soil was two or three centimeters thick and covered with straw or weeds. After 20 days, the seeds began to germinate. After that, the covering was gradually removed and the seedlings emerged in 30 to 50 days. Seedlings due to imperfect root development, stagnant water, torrential rain, high temperature, exposure and so on will cause their death, so the usual management should be extra careful.

2. Cuttage: generally carried out in March, or in mid-September. Cut the current or annual twigs as cuttings and cut off some leaves to reduce water evaporation and ensure survival. Rooting powder and other drugs can also be used to promote rooting. Insert in coarse sand, vermiculite or other media with good drainage and permeability, insert rear service watering, spray water frequently, keep the medium and air moist, avoid hot sun exposure, the survival rate is quite high.

3. Crimping: bamboo and cypress mostly adopt the method of high-altitude striping, select strong and full annual branches in the growing season, cut them in a suitable position, then wrap the soil at the wound, and then wrap the soil tightly with plastic bags to keep it moist. After rooting, cut it and plant it in the pot.

Culture methods of Bamboo and Cypress

1. Soil: bamboo and cypress have strict requirements on soil, and it is suitable for deep, loose, moist, thick humus layer and acidic sandy loam to light clay developed in sand shale, granite, metamorphic rock and other parent rocks.

2. Moisture: bamboo and cypress grow well in areas with an average rainfall of 1200mm to 1800mm, while those with rainfall below 800mm grow poorly and prefer areas where they are moist but free of stagnant water.

3. Light: bamboo and cypress is a shade-tolerant tree species, the growth rate on the shady slope is 5-6 times faster than that on the sunny slope, and sunburn or death will occur on the root neck of the sunny slope.

4. Temperature: the most suitable annual average temperature of bamboo and cypress is 18-26 ℃, the cold resistance is weak, and the extreme minimum temperature is-7 ℃, otherwise it is vulnerable to low temperature.

5. Fertilization: bamboo and cypress are resistant to barren, it is best to apply acid fertilizer when applying fertilizer, and the watering solution is the best, so we should apply less diligently.

6. Pruning: when bamboo and cypress plants enter dormancy or semi-dormancy period in winter, the branches such as thin, disease and insect, withered and overdense should be cut off.

Matters needing attention of bamboo and cypress

The main results are as follows: 1. 1-2 months after the seedlings were unearthed, the aboveground parts grew slowly, and the ability to resist external adverse factors was poor. In addition, bamboo and cypress seedlings were shade-tolerant and avoid stagnant water, so heavy rain, high temperature and sun exposure would cause a large number of seedlings to die. Therefore, we should set up a shed to cover the shade after the seedlings are unearthed, the shading material is strong and firm, and does not hurt the seedlings, generally using Reed curtains, the sunshade net is the best.

2. The insect diseases of bamboo and cypress are mainly red spiders, shell insects, anthracnose and leaf spot. To control red spiders, it is necessary to spray triclofenac, nisolan, chlorpyrifos, chlorpyrifos, and so on. To treat anthracnose and leaf spot, it is necessary to spray carbendazim, tocopherol, love seedlings and so on.

3. Bamboo and cypresses are curved when they are first unearthed, growing stems first and then leaves. The unearthed rhizomes are easy to be infected by fungi, because methyl carbendazim and carbendazim are sprayed alternately, weeds should be weeded frequently in seedling stage, bamboo and cypress sprouts are tender, water and fertilizer management should be strengthened and watered at regular intervals.
