1 by specification

The specifications of cypress bonsai are divided according to plant height or space length. The height of plants is calculated by the height from the roots of soil surface to the top, and the space length from the roots of soil surface to the tips of floating branches is calculated for cliff-type, cross-drought-type and water-facing bonsai. The modeling of cypress bonsai is generally carried out in winter dormancy or early spring. At this time, modeling has little effect on plant growth, but it also has the disadvantage of slow wound healing. In winter, if there is a greenhouse or shed, it can also be trimmed and shaped; If you are outdoors, you can only trim it, not make it flat.

2 cypress bonsai tree species and techniques

(1) For young cypress trees cultivated by methods such as sowing, cutting and layering, the trend can be determined according to the shape and branching of the tree. If the trunk of cypress is too straight, it should be slightly tilted when planting to increase the dynamic potential of the tree. According to the needs of modeling, cut short or bend, cut off branches that are not needed for modeling, and then tie them tightly with metal wires to gradually improve their modeling.

(2) For Sabina chinensis, firstly, according to the different thickness of branches, metal wires with different thicknesses are selected to be wound on them, and twisted while winding. Some people say that no matter what the shape of cypress bonsai is, there must be several bright spots (generally 1 ~ 3), and then the shapes of other parts should be centered around several bright spots, just like a big play, leading role and supporting role, so as to make the works clear and have higher appreciation.

(3) The stump is the main feature of cypress bonsai modeling, which is difficult. It requires the producer to have rich bonsai knowledge, be familiar with the habits and morphological characteristics of different species and varieties of cypress, and be skilled in using power tools and hand tools, so as to freely use the carving and drawing skills of sarira and sacred branches.

(4) Pay attention to the timing when making the relic, and March to May is appropriate, because the juice is active at this time, and the incision is easy to heal and swell; When you make a magic branch, you should always choose more forks, so that you can look good and look good.

3 Maintenance and management of cypress bonsai

The maintenance and management of cypress plants should not only ensure the normal life activities, but also control the original shape of the stump on the basis of the maintenance of cypress bonsai, maintain the continuity of plastic arts and show the artistic charm of the stump landscape. Therefore, the maintenance and management of cypress bonsai is a combination of technology and art, and the management of cypress bonsai is difficult. ① The planted soil is small and thin, and the nutrient elements in the soil are extremely limited, which is not conducive to the growth and daily management of cypress plants. Therefore, watering, fertilizing, turning pots, shaping and shading all need careful consideration. ② The bonsai has poor resistance to environmental conditions. Due to the small basin, shallow basin, little soil and thin soil, it has no resistance to high temperature, extreme heat, strong sunshine, strong wind and freezing, so corresponding protective measures must be taken.

3. 1 environment

Cypress likes sunny, warm and humid environment. The molded cypress bonsai can be maintained outdoors in sunny and airy conditions during the growing season. However, it should be properly shaded in midsummer to avoid exposure to the scorching sun, and it can be maintained in a semi-shady place without direct sunlight, or in a place where sunshine can be seen in the morning and evening without strong light at noon, and good ventilation should be paid attention to.

3.2 watering

The cypress bonsai should be watered frequently during the growth period to keep the soil moist, but there should be no water in the basin to avoid root rot. Cypress likes humid air. When the air is dry, it adapts to plants and the surrounding ground to spray water, making it form a local humid microclimate. Wash away the dust on the leaves, so that the leaves are green, pleasant and full of vitality.

3.3 Fertilization

In the growing season, cypress bonsai can be applied with 1 times of decomposed dilute liquid fertilizer every 20 days, and fertilization should not be too frequent, so as to avoid excessive fertilizer and water, which will cause plants to grow white and affect the beauty of trees. Fertilization in late autumn and winter can effectively promote stem thickening and root development.

3.4 Turn over the basin

Small and medium-sized cypress bonsai can be turned 1 time every 2 ~ 3 years, and large cypress bonsai can be turned 1 time every 3 ~ 4 years, usually before germination in spring. If the original flowerpot is too small, you can replace it with a larger flowerpot and change the shape as needed to improve the ornamental of the bonsai and make it always new. When turning the pot, you should trim the root system, remove some old soil and replant new culture soil. Potted soil should be rich in humus, fertile and moist, loose and breathable, and well drained. Can be mixed with humus 2, sand 1, and the feet and bones of rotting animals are placed under the flowerpot as base fertilizer. If it is a deep basin, coarse sand and gravel should also be put in the basin to increase drainage permeability.

3.5 Plastic Surgery

Pruning and shaping of cypress bonsai should be carried out in winter, and redundant branches, branches with bad angles and other branches that affect the tree shape should be cut off. For the branches that are too long, the top can be removed during the growth period to promote new shoots and make the branches dense. Bonsai of cypress trees, such as cypress and juniper, sometimes grow long notes during maintenance, so they should be cut off in time to avoid damaging the beauty of the trees. During the growth period, ears should be picked frequently, the elongation of paper strips should be controlled, the growth of lateral branches should be promoted, and the branches should be short and dense. There will be many buds sprouting from the periphery of the crown, so it should be cut short to keep the crown dense and beautiful. It is best to use bamboo scissors, copper scissors or nail clippers instead of iron scissors to avoid rust spots on the wound and affect viewing.

The real cypress bonsai should not be pruned too much, otherwise there will be prickly leaves, which will take a long time to recover into scales. After the rainy season every year, some old leaves of real cypress will wither and turn yellow. We can remove them and other dead leaves, dead branches and weak branches to keep the ventilation and light transmission inside the crown and improve the ornamental value of bonsai.

4 pest control

The pests and diseases of cypress bonsai mainly include rust and red star disease. Pests include red spiders that harm leaves; Attention should be paid to the control of Monochamus alternatus.
