Luohansong is a kind of pine, also known as Luohanshan, evergreen Luohanshan, Tujia, Qianqian pine, Xianbai, luohanbai and Jiangnan cypress. It is an evergreen tree. In the past, I often heard the old people say that the family planted Luohan pine will not be poor for generations! So, do you know how to cultivate luohansong? Let's have a look
Cultivation method of Luohan pine
1. Watering method of luohansong culture
Luohan pine has very strong vitality. It can resist drought and barren. It has no strict requirements on fertilizer and water. It is suitable to grow in various environments. However, for potted luohansong, the basin bottom should have drainage capacity and can't accumulate water for a long time, otherwise it will rot roots, so it's better to master a little dry when watering; The florist said: it makes sense to water luohansong by 'three parts wet and seven parts dry'. It is known from long-term practice that if watering is excessive, the basin soil will be watered for a long time.
Luohan pine will have black roots and yellow leaves. In serious cases, a large number of leaves will fall off and the plant will die. In case of this situation, rescue should be carried out in time. The method is to remove the basin soil and put the basin in a shady and ventilated place to evaporate the basin soil and remove the water as soon as possible. At this time, the roots of Luohan pine have completely lost their absorption capacity, and the grower has to spray water on the leaf surface, So that it does not lose or less water. After the plant is restored to the cattle machine, it can be saved by covering the soil and spraying water. Generally, it will not die.
Luohan pine is more drought resistant, so watering in the growing season should grasp the principle of better dry than wet, and keep the basin soil wet. If you water too much, the basin soil will be watered for a long time, which will lead to rotten roots and yellow leaves. In serious cases, a large number of leaves will fall off, and the plant will die. The water evaporates quickly in the high temperature season in summer, and the watering should be sufficient. If the basin soil is too dry and scorched, it will also affect the viewing.
2. Soil selection for culture of Pinus grosvenorii
When potting, use humic soil instead of alkaline soil. It likes loose, fertile and slightly acidic soil with good drainage, and is not resistant to saline alkali and barren.
3. Temperature requirements for luohansong culture
Luohan pine likes warmth and has weak cold tolerance. When the temperature drops to 13 ℃ in winter, it will enter the dormant state. At this time, the minimum temperature should not be lower than 10 ℃.
4. Fertilization method of Luohan pine culture
Potted Luohan pine also needs to supplement nutrients. Luohansong doesn't like concentrated fertilizer. In the growing season, it can use rotten organic liquid fertilizer with the concentration of 1:6, 1:8 and 1:10. It should be applied every ten days and a half months. Water should be injected the next day after fertilization, which is conducive to root absorption. Luohansong cultivated in the open field can apply organic liquid fertilizer with the concentration of 1:4 before spring shoot germination and after autumn shoot growth. During the construction, the ditch shall be dug, and the soil shall be covered after the construction. The next day, it shall also be irrigated with water. At ordinary times, it can not be fertilized. If there is no rain for a long time, water should be poured. If you want to watch its green leaves, whether potted or planted in the ground, you can add a small amount of liquid fertilizer in the water at the concentration of 1:15 every half month for watering, and water the flowers with muddy water.
It can grow well by applying 2 ~ 3 times of thin liquid fertilizer dominated by nitrogen fertilizer in spring and autumn. Water should be poured the next day after fertilization, which is conducive to the absorption of roots.
5. Light requirements for luohansong culture
Luohansong is able to withstand 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 Luohan pine also needs sunshine and rain. Therefore, after a period of indoor cultivation, we should move out and put it in the courtyard, balcony and 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 plants in the room, but also make Luohan pine grow vigorously.
6. Basin changing method of luohansong culture
For potted luohansong, it is best to turn the basin and change the soil every two years, which can be carried out in spring and autumn. Because Luohan pine has developed roots, strong sprouting power and green branches and leaves all year round, it needs to consume a lot of nutrients in the growth process of a year. If you grow for two years, the basin wall is basically full of fibrous roots, and the fertility of the soil is basically exhausted.
Therefore, we must turn over the basin and change the soil. The culture soil can be divided into 2 parts of forest rotten leaf soil, 2 parts of mountain soil, 2 parts of humus soil, 2 parts of pond soil and 2 parts of rotten manure. It can be fully mixed, exposed to the sun for several days, finely screened, and mixed with a small amount of culture soil when it is put into the basin as the base fertilizer. When turning the basin, take out the soil mass, remove the attached old soil, and properly trim the long root system and corrupt fibrous roots. Trim the over dense branches and replace them with new culture soil.
During cultivation, pay attention to the extension of the root system, cover the soil to 2cm along the basin, pour water once, put the flowerpot in a shady 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 after luohansong recovers its vitality.
7. Propagation method of Luohan pine culture
Pinus grosvenorii is usually propagated by sowing and cutting.
(1) Sowing and propagation of Pinus koraiensis
It can be carried out in August. It is generally carried out in the open seedbed. Pick and broadcast. Cover with straw, pay attention to shade and keep the substrate moist. Cover with plastic film to prevent freezing in winter.
(2) Cutting propagation of Pinus grosvenorii
It can be carried out in spring and autumn. Spring was inserted in mid March, and 1-year-old strong dormant branches were selected as cuttings; Semi lignified green branches were selected as cuttings in autumn from July to August. Ear cuttings should be with heels and pay attention to shade. Transplantation in March was the most suitable.
Precautions for culture of Pinus grosvenorii
(1) When the outdoor temperature drops to 5 ℃ in winter, it shall be moved indoors. After entering the room, watering shall be controlled and fertilization shall be stopped. Generally, the basin is changed every 2 years. The basin change time can be in spring and autumn. When changing pots, pay attention to appropriately cut off excessive roots and rotten fibrous roots, cut off over dense branches and add new culture soil.
(2) The growth season of luohansong is better if the basin soil is slightly dry. If you water too much and the basin soil is wet 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, the water demand is large in summer, and the watering should be sufficient. The basin soil is too heavy, and the leaves are easy to scorch.
(3) During the growth period, pay attention to pruning and coring the formed plants to prevent excessive growth of branches and leaves, and maintain the beautiful posture of Luohan pine. When changing pots, pay attention to cut off too many roots and rotten fibrous roots, and cut off too dense branches and bare branches at the same time.
(4) Potted Luohan pine should be placed on a high platform or stone Deng at ordinary times. In this way, insects such as ants and earthworms can be reduced from drilling into the flower pot from the bottom hole of the flower pot and endangering the plant.
Feng Shui application of luohansong
In Chinese traditional culture, luohansong symbolizes longevity, frugality and auspiciousness. In Guangdong, there is a saying among the people that "there is luohansong at home, and the world will not be poor". Ancient Chinese officials also liked to plant Luohan pine in the courtyard and regarded it as the patron saint of their official position. In some places, luohansong is endowed with the embodiment of gods. In the village, the ancient luohansong, even if the times are developing and everything is changing, people will not easily move this' treasure of town and village '. People always think that it is a kind of guardian, which can bring people peace, happiness, wealth and so on.
