Culture methods and matters needing attention of Luohansong

Luohansong is an evergreen tree. Leaves spirally alternate, strip-lanceolate, apex pointed, base narrow into petiole shape, rib raised on both surfaces, surface dark green, abaxially yellowish green, flowers bisexual, male cones spikelike, often 3-to 5-fascicled in leaf axils; female flowers usually solitary in leaf axils, pedicellate. Flowering in May. Receptacle hypertrophy, fleshy, seeds broad-shaped, born on the receptacle.

It is native to China and is widely cultivated in the Yangtze River Basin and the southeast coast. Like warm, moist, semi-overcast environment. The sandy loam, which is fertile and well drained, can also adapt to the climate of the coastal plain and has weak cold resistance. here is a detailed introduction to how to raise Luohansong.

1. Soil selection of Pinus elliottii Culture

Use humic acid soil when potting, do not use alkaline soil. Like loose, fertile and well-drained slightly acidic soil, not resistant to salinity and barren.

two。 Fertilization method for cultivation of Pinus elliottii

Potted Luohansong also needs to be supplemented with nutrients. Luohansong does not like thick fertilizer, so mature organic liquid fertilizer can be used in the growing season at the concentration of 1:6, 1:8 and 1:10, applied every ten days and a half month, and irrigated the next day after fertilization, which is beneficial to root absorption. Luohansong cultivated in the open field can apply organic liquid fertilizer with a concentration of 1:4 before spring shoot germination and after autumn shoot growth. Dig ditches during application, cover the soil after application, and irrigate once the next day, usually without fertilization. If there is no rain after a long drought, irrigation is needed. If in order to enjoy its green leaves, no matter potted or planted on the ground, you can use 1:15 concentration to add a small amount of liquid fertilizer to the water every half month to irrigate the flowers with muddy water.

The rarefied liquid fertilizer dominated by nitrogen fertilizer can grow well when it is applied 2 or 3 times in spring and autumn respectively. Water should be watered once the next day after fertilization, which is beneficial to the absorption of roots.

3. Watering method of Pinus elliottii Culture

Luohansong, has a very strong vitality, it can withstand drought, resistance to barren, fertilizer and water requirements are not strict, it is suitable to grow in a variety of environments. However, for potted Luohansong, the bottom of the pot must have the ability to drain water for a long time, otherwise the roots will rot, so when watering, it is better to be slightly dry. The florist said that the watering of Luohansong should be "three percent wet and seven percent dry." this is very reasonable. It is known from the long-term practice that if the watering is excessive, the basin soil will be water-stained for a long time.

Luohansong will have black roots and yellow leaves, and when it is serious, a large number of leaves will fall off and the plant will die. if this is the case, the rescue should be carried out in time. The method is: peel off the basin soil and put the pot in a shaded ventilation place to make the basin soil evaporate and remove water as soon as possible. At this time, the root system of Luohansong has completely lost its absorptive capacity, and the grower should spray water on the leaf surface in a fog so that it does not lose or lose less water, and after the plant recovers the cow machine. Then covered with soil and sprayed with water, it can generally be saved without death.

Luohansong is more resistant to drought, so watering in the growing season should grasp the principle of dry rather than wet, and keep the basin soil wet. If too much watering, basin soil long-term water stains, will lead to rotten roots, yellow leaves, serious leaves fall off a large number, the plant will die. Water evaporates quickly in summer high temperature season, watering should be sufficient, if the pot soil is too easy to scorch the leaves, it will also affect the ornamental.

4. Lighting requirements of Pinus elliottii Culture

Luohansong can bear shade, but it is not suitable to stay indoors for a long time in the growing season. Because the indoor light and air humidity are not as good as outdoor, the growth and development of Luohansong also needs sunshine and rain. Therefore, after being nurtured indoors for a period of time, it is necessary to move out and put it in the courtyard, on the balcony and on the platform, so as to restore its vitality as soon as possible. It is best to raise two more pots and implement the system of regular rotation. In this way, it can not only keep indoor plants for viewing, but also make Luohansong grow vigorously.

5. Temperature requirements for culture of Pinus elliottii

Luohansong likes warmth and has weak cold resistance. When the winter temperature drops to 13 ℃, it goes into dormancy, and the lowest temperature should not be lower than 10 ℃.

6. The method of changing pots in the culture of Luohansong

Potted Luohansong, it is best to turn the pot every two years to change the soil, the time can be carried out in both spring and autumn. Because Luohan pine has developed root system, strong germination, green branches and green leaves in four seasons, it needs to consume a lot of nutrients in the growth process of one year. If cultivated for two years, the basin wall is basically covered with fibrous roots, and the fertility of the soil is basically exhausted.

Therefore, the basin must be turned over to change the soil. 2 parts of forest rotten leaf soil, 2 parts of mountain soil, 2 parts of humus soil, 2 parts of pond soil, 2 parts of mature barnyard manure, fully mixed, exposed to the sun for several days, sifted carefully, and mixed with a small amount of culture soil mixed with rotten oil withered powder and dried pig manure as base fertilizer. When turning the basin, take the soil mass out, remove the attached old soil, and trim the excessively long roots and rotten fibrous roots properly. Trim over-dense branches and replace them with new cultivated soil.

During cultivation, the root system should be extended, cover the soil to 2 cm along the edge of the basin, water once, put the flowerpot in a shaded and ventilated place, slow the seedlings for 7 to 10 days, and then move to a sunny and humid environment to keep the basin soil moist and make it grow vigorously.

7. Matters needing attention in the Culture of Luohansong

The main results are as follows: (1) the basin soil is slightly dry in the growing season. If the basin soil is watered too much and the basin soil is moist for a long time, it will lead to rotten roots and yellow leaves. In severe cases, a large number of leaves fall off, and the plant eventually dies. However, there is more water demand in summer, watering should be sufficient, and the pot soil is easy to scorch if the leaves are too much.

(2) during the growth period, attention should be paid to pruning and coring the molded plants to prevent the branches and leaves from growing, and to maintain the graceful posture of Luohansong. When changing the basin, we should pay attention to cut off too many roots and rotten fibrous roots, and at the same time cut off the dense branches and growing branches.

(3) when the outdoor temperature drops to 5 ℃ in winter, it should be moved indoors, watering should be controlled and fertilization should be stopped after entering the house. Generally every 2 years to change the basin, the time to change the basin in spring and autumn. When changing the basin, pay attention to properly cut off the excessive root system and rotten fibrous root, cut off the overdense branches and add new culture soil.

(4) potted Luohansong is usually placed on a high platform or stone, so that insects such as ants and earthworms can be reduced to drill into the flowerpot from the bottom hole of the flowerpot, harming the plant.

8. Breeding methods of Pinus elliottii

(1) sowing and propagation of Pinus elliottii

It can be carried out in August. It is generally carried out in the open field seedbed. Broadcast on demand. Cover straw, pay attention to shading, and keep the substrate moist. Anti-freezing should be covered with plastic film in winter.

(2) Cuttage propagation of Pinus elliottii

It can be carried out in spring and autumn. Spring was planted in the middle of March, one-year-old stout dormant branches were selected as cuttings, autumn was inserted in July to August, and semi-lignified green branches were selected as cuttings. Cuttings should have heels and pay attention to shade. March transplantation is the most suitable.

Soil selection

Use humic acid soil when potting, do not use alkaline soil. Luohansong likes loose, fertile and slightly acidic soil with good drainage, and is not resistant to salinity and barren.

Water and fertilizer management

Watering: Luohansong is more resistant to drought, so watering in the growing season should grasp the principle of dry rather than wet, and keep the basin soil wet. If too much watering, basin soil long-term water stains, will lead to rotten roots, yellow leaves, serious leaves fall off a large number, the plant will die. Water evaporates quickly in summer high temperature season, watering should be sufficient, if the pot soil is too easy to scorch the leaves, it will also affect the ornamental.

Fertilization: potted lohan pine also needs to be supplemented with nutrients. Luohansong does not like thick fertilizer, the growing season can use mature organic liquid fertilizer, the concentration is 1:6, 1:8, 1:10, once every ten days and a half month, the next day after fertilization should be irrigated, which is conducive to root absorption.

Temperature and light

Temperature: Luohan pine likes to be warm and has weak cold resistance. When the winter temperature drops to 13 ℃, it goes into dormancy, and the lowest temperature should not be lower than 10 ℃.

Lighting: Luohansong, can withstand shade, but the growing season should not be stuffy indoors for a long time. Because the indoor light and air humidity are not as good as outdoor, the growth and development of Luohansong also needs sunshine and rain.

Mode of reproduction

Sowing and reproduction: can be carried out in August. It is generally carried out in the open field seedbed. Broadcast on demand. Cover straw, pay attention to shading, and keep the substrate moist. Anti-freezing should be covered with plastic film in winter.

Cutting propagation: can be carried out in spring and autumn. Spring was planted in the middle of March, one-year-old stout dormant branches were selected as cuttings, autumn was inserted in July to August, and semi-lignified green branches were selected as cuttings. Cuttings should have heels and pay attention to shade. March transplantation is the most suitable.

Points for attention of Luo Hansong's domestic upbringing

Guard against apprentices

During the growth period, attention should be paid to pruning and coring the molded plants to prevent the branches and leaves from growing, and to maintain the graceful posture of Luohansong. When changing the basin, we should pay attention to cut off too many roots and rotten fibrous roots, and at the same time cut off the dense branches and growing branches.

Prevent frostbite

When the outdoor temperature drops to 5 ℃ in winter, it should be moved indoors. After entering the room, watering should be controlled and fertilization should be stopped.

Prevention of insect pests

Potted Luohansong is usually placed on a high platform or stone, so that insects such as ants and earthworms can be reduced to drill into the flowerpot from the bottom hole of the flowerpot, harming the plant.

Luo Han Song, I believe many people are very familiar with it, this is a very common evergreen coniferous tree, how to raise Luo Han Song? The knowledge brought to you today is the breeding methods and matters needing attention of Luohansong.

The culture method of Luohansong:

1. Soil: a slightly acidic culture soil rich in humus, loose and fertile, and good drainage is required. In alkaline soil, the leaves are yellowed, the growth is slow, and the life span is long, up to hundreds of years, or even more than a thousand years.

2. Watering: Luohansong is not a plant of Pinaceae and is not resistant to drought. On the contrary, Luohansong is resistant to Yin and dampness, so it should be watered frequently during the growing period, but it should not be watered. Shunde area should pay attention to regular watering when it is sunny in summer, generally watering once in the morning and evening, and often spraying foliar water to make the leaves bright green and grow well. Rain Water is usually more in summer. Luo Hansong is not resistant to waterlogging, so we should pay attention to prevent stagnant water for a long time.

3. Sunshine: Pinus elliottii is a neutral and negative tree species, which can not only accept strong light, but also grow in a shady environment. Although the temperature is high and the sun is strong in summer, it is not necessary to shade the tree in summer because the tree is propitious to maintain its leaf shape under the condition of high temperature and strong light. Because of the tender tissue, the seedlings of Luohan pine should not be exposed to strong light for a long time, so it is suggested that they should be preserved in the shade.

4. Temperature: potted plants in the north, leave the room when the outdoor temperature is stable at about 10 ℃, put it outside in the leeward and sunny place, and move to the semi-shady place after summer. When the temperature does not drop to 5 ℃ in winter, you should enter the room and control the watering after entering the room, so that you can survive the winter safely without freezing.

5, fertilization: Luohansong likes fertilizer, should be thin fertilizer frequently, fertilizer is mainly nitrogen fertilizer, can add appropriate amount of black alum, retting into alum fertilizer water. During the growing period, fertilization can be applied once every two months, and fertilization can be combined with watering at the same time (the ratio of water and fertilizer is 9:1).

6. Insect pests: there are mainly leaf spot disease and anthrax, sprayed with 50% methyl topiramate wettable powder 500 times. Pests are harmful to shell insects, red spiders and coir moths, which can be sprayed with 1500 times omethoate EC.

Matters needing attention in Luohansong culture:

1. Luohansong likes to be fertile, and it is better to choose fertile soil as far as possible, such as sandy loam and rotten leaf soil. of course, the air permeability and drainage of the soil also need to be very good. During the bonsai culture period, we also need to pay attention to keeping the basin soil moist to ensure adequate water supply during the growth period of Luohan pine. Water evaporates quickly in summer and needs frequent watering. If the temperature is low in winter, watering needs to be reduced. At the same time, in order to avoid the occurrence of stagnant water in the basin, watering must be moderate, not too much and not too wet. At the same time, we should also pay attention to put the lohan pine bonsai in a ventilated place.

2. Luo Hansong likes the light, but he is also very taboo about direct sunlight, so it is usually best to keep it indoors. At the same time, when the summer sun exposure, pay attention to its shade. In addition, when the Pinus elliottii grows to a certain extent, its plant becomes larger, so it needs to change the flowerpot. In addition, we should also pay attention to pest control and regular pruning for Luohan pine bonsai. Luohansong still has a lot of diseases and insect pests, so if it is found during the breeding period, it should be dealt with in time, and the pruning work can be carried out according to everyone's ideas, usually by means of cutting, pruning and pressing.
