Making and Maintenance of Sabina chinensis Bonsai

Juniper, also known as garden cypress, is an evergreen tree of the cypress family, which is an excellent material for foliage tree stump bonsai.

First, the production of juniper bonsai

1. Draw materials. Juniper is widely distributed in China. Before bonsai sprouting in spring, wild tree stumps are often excavated in the mountains for cultivation and processing; sand can also be collected when the seeds are ripe, and after about one year, they can be sown and nursery; they can also be propagated by tender wood cuttings in May to June or hardwood cuttings in September to October, and strip propagation can also be carried out in the plum rain season.

two。 Styling. Juniper usually uses the method of "combination of cutting and binding" for processing and modeling, and the banding is mostly carried out in late autumn and early winter, preferably with brown silk, white Ramie silk, hemp rope, plastic strip, etc., and metal wires such as copper wire, lead wire and iron wire can also be used for flat binding, and the flat binding material can be removed in time after shaping, so as to prevent the sinking of the wire and affecting the plant growth and the beauty of the tree. The larger branches and stems can be "carved" according to the creative idea and conception, and most of the branches and leaves are trimmed into semicircle or lamellar shape.

3. Put in the pot. It is better to transplant the upper pot from March to April in spring, choose glazed pottery basin or purple sand pottery basin. The shape of the basin depends on the tree type, the curved dry type and horizontal dry type use rectangular or oval basin, the straight dry type is commonly used in the medium-deep round basin, and the cliff type uses the high-deep barrel basin. The cultivation soil is made up of loose and fertile sandy loam with good drainage and permeability. Pastoral soil, grass carbon soil, humus soil and so on can be mixed with appropriate amount of sand and bran ash. When transplanting on the pot, it is required that the root of the plant (tree stump) should take the soil, and it is not suitable for bare root transplanting.

II. Key points of maintenance and management

1. Water and fertilizer management. Timely watering, usually keep the basin soil properly moist. Pay attention to prevent stagnant water in the basin in the rainy season; when the temperature is high in summer and early autumn, water should be watered early and late or foliar spray to keep the basin soil and environment moist. The thin and rotten cake fertilizer and water were applied 2 times every year from April to May and from September to October, and an appropriate amount of high-quality organic fertilizer was sprinkled on the basin at the beginning of June every year. It is not suitable to apply fertilizer in other seasons.

two。 Light and temperature requirements. The juniper is fond of light, shady and cold-resistant when young. Bonsai should be maintained in a ventilated and sunny place; sunshade nets and bamboo curtains should be used in summer and early autumn; and winter can be overwintered in the leeward and sunny outdoors.

3. Turn the basin and trim. Turn the basin and change the soil every 3-4 years, from March to April, remove the old soil, cut off part of the old roots, cut short and long roots, and cultivate the loose and fertile new culture soil to promote the growth of new roots. Every year in the growing season, we should carry out heart-picking shoot, the more heart-picking, the denser the crown, the higher the ornamental effect.

4. Pest control. Juniper bonsai has fewer diseases and pests, but rust sometimes occurs. 20% Fenghuxing wettable powder 1200-1500 times can be sprayed on the leaves at the initial stage of the disease, once every 5-7 days, 2 times in succession; occasionally, red spiders can be used to dilute 400-600 times with essential oil.
