The production of Luohansong bonsai: Miaoyuan and pruning modeling techniques

Luo Hansong is a small evergreen tree of Pinaceae. It is evergreen all the year round, long and narrow needles, dark green color, vigorous branches and long life, so it is a commonly used tree species for bonsai production. Among them, sparrow tongue Luohan pine, the leaf is only 2 cm long, the tree shape is beautiful, it is a valuable tree species for making bonsai. Luohansong likes warm and humid environment, shade tolerance, like fertile, loose, well-drained, slightly acidic sandy loam.

The method of making bonsai is as follows:

First, the seedlings of Miaoyuan Luohan pine bonsai are usually obtained by artificial propagation techniques such as sowing and cutting. There are also wild Luohansong in the mountains, which are generally born in stone crevices. Optional short plants, quaint branches, graceful mining.

Second, modeling

The main results are as follows: 1. Pinus elliottii is usually put on the basin before germination in spring, and the basin soil should be made of slightly acidic sandy loam with loose texture and good drainage. As the posture of Luohansong is simple and elegant, it is appropriate to choose purple sand basin or glazed pottery basin for cultivation, and the shape of the basin is determined by the shape of the tree.

2. The styling of Luohansong is mostly carried out in the dormant period, with flat binding as the main and pruning as the auxiliary. Because the branches of Luohansong are soft, easy to tie, and can be trimmed, so the shape is diverse. The common forms are curved dry type, oblique dry type, horizontal cloud type, cliff type and root type and so on. Branches and leaves can be trimmed into flakes or steamed buns.

3. Maintenance

(1) the site of Luohansong should be placed in a warm, humid and well-ventilated place in summer and indoors above 5 ℃ in winter. But the temperature should not be too high, so as not to affect its dormancy.

(2) watering the moist soil of Luohansong, the growing season should be often watered to keep the basin soil moist, but the basin should not be watered. In summer, water is often sprayed to the leaves or the ground to keep the leaves bright.

(3) it is not suitable to apply more fertilizer to the formed lohan pine. Usually in the growing season, mature thin liquid fertilizer is applied every other month, and no more fertilizer is applied after autumn.

(4) pruning Luohan pine should be pruned frequently to maintain the shape of the tree. When blooming, it is best to remove the buds in time so as not to consume nutrients.

(5) Luohansong usually turns the basin every 3 years. It usually takes place from March to April.

(6) the prevention and control of diseases and insect pests should be paid attention to, especially in summer and high temperature seasons, and attention should be paid to the prevention and control of shell insects and red spiders. The common diseases are coal fouling disease and leaf spot disease. 0.5% Bordeaux solution can be used one month before the plum rain season. Spraying once every 10 days for 3 times in a row can achieve the control effect. The main pests are big coir moth, red wax shell insect, red spider and so on, which can be sprayed with enemy 1200-1500 times or 40% dimethoate 1500 times.

Knowledge of bonsai production, cultivation and maintenance of Luohansong

The author mainly introduces the production and cultivation techniques of bonsai of Luohan pine.

Luo Hansong is a small evergreen tree of Pinaceae. It is evergreen all the year round, long and narrow needles, dark green color, vigorous branches and long life, so it is a commonly used tree species for bonsai production. Among them, sparrow tongue Luohan pine, the leaf is only 2 cm long, the tree shape is beautiful, it is a valuable tree species for making bonsai. Luohansong likes warm and humid environment, shade tolerance, like fertile, loose, well-drained, slightly acidic sandy loam. The method of making bonsai is as follows:

I. Miaoyuan and Culture

The seedlings of Pinus elliottii bonsai are usually obtained by artificial culture techniques such as sowing and cutting. There are also wild Luohansong in the mountains, which are generally born in stone crevices. Optional short plants, quaint branches, graceful mining. Culture method: commonly used cutting method, can also be used by sowing method and grafting method. The cutting time is in the middle of March or the rainy season from June to July. The cuttings should be with heel and the seedling bed should be shaded. Spring March is the most suitable for transplanting. Sowing seeds are collected in late August and sowed with picking, or stored in sand until March of the following year. Because of the slow growth of cuttings, it is suitable to use large leaves or lobules as rootstocks, and the survival rate is higher when grafted in March in early spring.

1. Upper basin

Luohansong usually goes to the basin before germination in spring, and the basin soil should be made of slightly acidic sandy loam with loose texture and good drainage. As the posture of Luohansong is simple and elegant, it is appropriate to choose purple sand basin or glazed pottery basin for cultivation, and the shape of the basin is determined by the shape of the tree.

2. Modeling

The styling of Luo Han Song is mostly carried out in the dormant period, mainly in Panzha, supplemented by pruning. Because the branches of Luohansong are soft, easy to tie, and can be trimmed, so the shape is diverse. The common forms are curved dry type, oblique dry type, horizontal cloud type, cliff type and root type and so on. Branches and leaves can be trimmed into flakes or steamed buns.

3. Cultivation and maintenance

Luohansong can not only be planted on the ground, but also can be potted, so the maintenance and management requirements are not strict. In the growing season of spring and autumn, only one or two times of nitrogen topdressing can be applied, and there is no need for too much phosphorus and potash fertilizer. For the modeled bonsai, we must pay attention to heart-picking and pruning to prevent the branches and leaves from growing, so as to maintain the original posture. Pruning and heart-picking work is best carried out during the growth period of spring and autumn. Family potted Luohansong should be kept in an outdoor ventilated place all the year round, not indoors for a long time, otherwise the leaves will fall off and die. Summer high temperature should not be exposed to the sun, should be placed in a semi-shady place for maintenance. In the growing season, the moisture can be slightly more; in the hot summer, the basin soil should be watered in time, and the water content in autumn and winter can be reduced appropriately. In winter in East China, when the temperature drops to 5 ℃, you should enter the house to survive the winter, and control the amount of watering, and the basin soil should be dry.

(1) venue

Luohansong should be placed in a warm, humid and well-ventilated place in summer and indoors above 5 ℃ in winter. But the temperature should not be too high, so as not to affect its dormancy.

(2) watering

(5) turn over the basin

Luo Hansong usually turns the basin every 3 years. It usually takes place from March to April.

(6) Disease and pest control

Attention should be paid to the prevention and control of diseases and insect pests, especially in summer and high temperature seasons, and attention should be paid to the control of shell insects and red spiders. Common diseases are coal fouling disease and leaf spot disease. 0.5% 0.1% Bordeaux solution can be used and sprayed once every 10 days for 3 consecutive times a month before the Meiyu season. The main pests are big coir moth, red wax shell insect, red spider and so on, which can be sprayed with enemy 1200-1500 times or 40% dimethoate 1500 times.
