First, growing habits
Snow likes warm and humid environment, light, shade, drought, pruning, a little cold, fertilization, not strict with soil, neutral and slightly acidic soil can adapt.
Second, the pile material source and processing modeling
Generally, in the snow, ramets are propagated in March in spring, and cuttings or root cutting propagation can be carried out at any time from February to June at 65438+1October. If the protected field (seedbed) is used for propagation, cuttings can be carried out from June of 65438+ 10 to June of the following year, and the survival rate is very high. 2-3-year-old seedlings can be processed and shaped, usually after defoliation in winter and before germination in spring. The trunk and main branches are coiled with metal wires, and the branchlets are finely trimmed and beautifully shaped. The branches in the snow are soft and easy to bend, but it takes a long time to set. It will take about 2-3 years for Pinza (that is, metal wire) to be dismantled, and it is best to decide several times to avoid the metal wire trapping and affecting the plant growth and tree appearance. In the southeast and central provinces of China, you can also dig wild old piles or young trees in Shan Ye, plant them in the ground and then process them into pots to "cultivate blanks".
Third, the technical points of the pot.
Snow should be transplanted into flowerpots from February to March, or during rainy season and late autumn. Choose shallow round, square or oval purple sand pottery basin or glazed pottery basin, the color of the basin should be slightly darker, in contrast to the design and color. Potted soil should be sandy loam rich in organic matter, loose and fertile, with good drainage and air permeability. Pastoral soil, humus soil and pine needle soil can be mixed, and 40% sand or rice husk ash can be mixed. When you are in the pot, trim the roots properly. For piles that need to be rooted and processed into open bonsai or processed into stone bonsai with elegant stones, they can be completed while you are in the basin. After the basin is put away, finely trim the upper branches and leaves (that is, cut off the branches and leaves that have nothing to do with the shape and affect the beautiful shape), and pay attention to proper shading and frequent water spraying to ensure their survival and normal growth.
Four, maintenance management technical points
1. Water and fertilizer management: 6. In the snow, bonsai should be watered frequently during the growing period to keep the soil moist, and foliar water should be sprayed 1-2 times a day in summer, and attention should be paid to patrol in rainy season to avoid water accumulation in the basin; In winter, the watering frequency should be reduced appropriately, and water should be poured every 3-6 days (when the surface of the basin soil is slightly dry and white). Pouring 0.3%-0.5% P-K fertilizer solution 2-3 times every year before flowering (i.e. April-May); Topdressing 1-2 times diluted organic fertilizer solution in winter is not suitable for fertilization in other seasons. Avoid applying thick fertilizer.
2. Requirements for light and temperature: The snow is a subtropical tree species, so strong light is prohibited, and it should be shaded by 50%-70% in summer. You can spend the winter outdoors in the south in winter; If you want to move indoors in the north, it is best to keep the room temperature at 5- 12℃.
3. Turnover and pruning: Generally, turn over pots and change soil every 1-2 years 1 time, in February-March in spring or late autumn. Remove all the old soil, trim the roots properly, and combine with changing pots to lift the roots to form hanging roots and improve the ornamental value. Every year, after defoliation in winter and before germination in the following spring, 1 pruning is carried out, such as pruning short and long branches, thinning over-dense twigs, pruning pests and diseases and other disorderly branches that affect appreciation; Core-picking, bud-wiping, branch-removing, etc. In the growing period, it should be carried out in time to maintain its beautiful appearance. The cut healthy branches can be used for cutting propagation.
4. Pest control: There are few pests and diseases in bonsai in the snow, and aphids and snails occasionally occur. Once it happens, we should prescribe the right medicine and control it in time. Aphids can be diluted 500-600 times with essential balm, or sprayed with neutral washing powder to kill water 150 times; Withdrawing 80% Miwoling granules to the basin surface or spraying 58% Fengleiji EC with 1500 times solution can kill Oncomelania hupensis. Root rot will occur if the soil in the basin is too wet or the water in the basin is too long, so attention should be paid to prevention and control. After the basin soil is hardened, it is necessary to turn over the soil in time, and be careful not to let the basin soil get too wet for a long time to avoid water accumulation in the basin. At the beginning of the disease, 600- 12% green milk copper emulsifiable solution or 800 times 50% root rot solution can be used to irrigate roots and leaves, and sprayed (irrigated) once every 3-5 days. For plants with serious illness, it is generally necessary to take them out of the pot, replace them with new culture soil, wash the roots, cut off the diseased roots, soak the roots with the above chemicals for 30 minutes, and then plant them in the pot again.
