How to breed and preserve Luohansong? How to shape a potted plant?

As a family growing flowers, the main purpose of cultivating Luohansong is to make bonsai stumps. It is naturally distributed in the mountains above 1000 meters above sea level in Jiangnan provinces, so it has a certain cold resistance, can withstand the low temperature of 0 ℃, is afraid of summer heat, and the suitable temperature for growth is 15-28 ℃. Like sunshine, but also quite shade-resistant, can be furnished in bright parts of the room. It is required that the slightly acidic soil with loose, fertile and good drainage is more resistant to drought and waterlogging.

The growth of sowing seedlings is slow, and cutting is easy to take root. Take full annual shoots as cuttings, preferably with terminal buds, cuttings 8-10 cm long, cut off leaf clusters below the middle, flatten the base with a blade, insert plain sand or vermiculite, soil depth 3 cm, cover with plastic film moisturizing, shade maintenance, rooting at 20-28 ℃ for 2-3 months, and seedling pot after half a year. If the incision can be treated with 0.3% a-naphthylacetic acid, the rooting time can be shortened and the survival rate of cuttings can be improved.

Pot use acid soil on the pot, after forming, plant into the bonsai basin, as long as the growth is normal, try not to turn the basin to change soil. Large plants for display in the courtyard can be trimmed into globular trees called "Luohan pine balls". It should be properly shaded in spring and summer, spray water frequently in dry season to increase air humidity, basin soil should be wet between dryness, and topdressing at the end of spring and early summer. 3 times, do not topdressing other times, in case the branches grow too long to reduce the cold resistance. The room temperature should not be too high in winter to prevent defoliation in spring.

How to breed and maintain Luohansong as a family to raise flowers, the purpose of cultivating Luohansong is mainly to make bonsai. It has strong cold resistance, can withstand a low temperature of minus 2-3 ℃, and is afraid of extreme summer heat, and the suitable temperature for growth is 15-28 ℃. Because it belongs to positive plants, it is not afraid of sun exposure and is quite shady. The acid soil which is loose, fertile and well drained grows especially well in humus soil, and the leaves of basin soil yellowed if it contains alkali. It is more resistant to drought and moisture. Pinus elliottii can be sown and propagated, and it can also be propagated by cuttings. the growth of sowing seedlings is slow, and cutting is easy to take root. Pick the tip of a full annual branch to do cuttings, preferably with a terminal bud, cuttings 8-10 cm long, cut off the leaves below the middle, flatten the base with a shaving blade, insert it into plain sand or vermiculite, the soil is 3 cm deep, cover with plastic film to moisturize, shade and maintain, rooting at 20-28 ℃ for 2-3 months, and then divide the seedlings into pots after cutting for half a year. If 3000 mg / L a-naphthalene acetic acid can be used to cut the cuttings, the rooting rate can be greatly increased and the rooting time can be shortened. When potting should use acid humus soil, can plant into bonsai shallow pot, as long as the growth is normal, try not to turn the basin to change soil. The old bonsai piles of Luo Hansong should not be exposed to the sun, and the large pots for courtyard display should also be properly shaded in spring and summer. In the dry season, water should be often sprayed to improve the air humidity, and the basin should be wet between dry and dry, topdressing 2-3 times in late spring and early summer, and then stop topdressing, so as to prevent the branches from overgrowing and reducing the cold resistance. Move to the cold room in winter and keep the room temperature for 0-10 ℃. If the room temperature is too high, there will be a lot of defoliation after the beginning of spring next year. If it is not for the production of bonsai, but only for potted ornamental plants, the trees should also be modeled reasonably. There are two modeling ways of Luohan pine: one is to let its top grow and grow into a conical crown; the other is to cut off the top of the plant by taking advantage of the low branches of the pine, and cut off the overlong side branches to form a low spherical crown, called "Luohan pine cone". Do not be careful with the side branches in the crown. The thicker the branches and leaves are, the higher the ornamental value is. Its leaves are small and dense, the branches are soft, easy to tie, and resistant to pruning. Not only can 2-3-year-old seedlings be used to make miniature bonsai, but also ancient stumps can be used to make large and medium-sized bonsai. How to raise pots of Luohansong? Culture method of Pot Culture of Pinus elliottii

How to breed pots of Luohansong? What are the specific planting methods of pots of Luohansong? Luohansong is generally distributed in the mountains in the south of the Yangtze River, the branches are old and energetic, and it is a kind of ornamental plant. Many people will buy a pot of Luohansong at home, which means longevity and health.

Culture method of potted Pine Pine

1. Potted soil. Sexual preference for warm, moist and semi-shady environment, suitable for fertile, moist and well-drained soil. When potted, rotten leaf soil or peat soil can be used to add 1 to 5 river sand, and mixed with a small amount of bone powder to prepare the culture soil.

2. Water and temperature. Luohansong is resistant to Yin and dampness, so it should be watered frequently during the growing period, but it should not be watered. In summer, we should often spray foliar water to make the leaves bright green and grow well. When the outdoor temperature is stable at about 10 ℃, leave the south balcony or courtyard leeward to maintain, move to the semi-shady place after summer, and pay attention to pour out the stagnant water in the basin in time after rain to avoid waterlogging. Water evaporates quickly in summer, watering should be sufficient, and the leaves of the basin soil are easy to scorch if they are too dry. Water should be watered once the next day after fertilization, which is beneficial to root absorption. Enter the room when the temperature drops to 5 ℃ in winter, control watering after entering the room, and keep the room temperature at 7: 8 ℃. Too high room temperature is disadvantageous to growth in the following year.

3. Fertilizer. The formed bonsai should not be fertilized more, apply dilute pancake fertilizer and water for 1 or 2 times in spring and stop fertilization in late autumn to avoid sprouting autumn buds, which is disadvantageous to overwintering. Or the dilute liquid fertilizer dominated by nitrogen fertilizer can grow well if it is applied 2 or 3 times in spring and autumn.

4. Plastic surgery. Luohan pine can be pruned all the year round, mainly cutting off long branches and diseased branches to maintain a beautiful tree shape. When blooming, it is best to pick the buds in time, so as not to consume nutrients and affect the growth potential. For the formed plants, pay attention to heart-picking and pruning to prevent the branches and leaves from growing, so as to maintain the original posture. Coring and pruning time can generally be carried out in the spring and autumn growing season.

5. Turn the basin. The basin can be turned once in 2-3 years, and it is better to do it in March-April in spring. When turning the basin, replace the old soil with 1 hammer and 2 old soil, and cut off the withered roots to stretch out the fibrous roots. If the plant is enlarged, it can be replaced with a larger pot. In addition, it can also be combined with turning the basin, gradually lifting the root, with rocks to shape the root-type or stone-attached bonsai, or changing the basin every 1-2 years, either in spring or autumn. When changing the basin, pay attention to properly cut off part of the excessive root system and rotten fibrous root, at the same time cut off the overdense branches and add new culture soil.

6. Pest control. Common diseases are coal fouling disease and leaf spot disease. 0.5%-1% Bordeaux solution can be used and sprayed every 10 days for 3 times in a row to achieve control effect. The main pests are large coir moth, red wax scale insect and red spider, which can be sprayed with dichlorvos 1 200 and 1 500 times, or 40% dimethoate 1 500 times.
