Maintenance technology of bonsai of Luohansong

(1) watering

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.

(2) fertilization

The formed bonsai should not be fertilized more, apply sparse cake fertilizer and water for 1 to 2 times in spring and stop fertilization in autumn to avoid sprouting autumn buds, which is disadvantageous to overwintering.

(3) pruning

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.

(4) turning the basin

The basin can be turned once every 2-3 years, and it is better to do it from March to 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 lift the root, attached with rocks, and shape the root-type or stone-attached bonsai.

(5) Disease and pest control

Common diseases are coal fouling disease and leaf spot disease. 0.5% Bordeaux solution can be used and sprayed once every 10 days for 3 consecutive times in the month before the plum rain season. The main pests are large coir moth, red wax shell insect, red spider and so on, which can be sprayed with dichlorvos 1200-1500 times or 40% dimethoate 1500 times.

Production and maintenance of bonsai of Luohan pine

Pinus elliottii, a small evergreen tree of Pinaceae, is a variety that has been mutated by long-lasting potted plants. It is evergreen all the year round, and its needles are like real beads. Brilliant green, vigorous branches, long life, is commonly used in the production of bonsai tree species, the tree shape is exquisite, is the production of bonsai valuable tree species. Rice leaf Luohan pine prefers gentle and humid environment, is more shade-tolerant, and prefers sandy loam with fertile, loose, well-drained and slightly acidic soil.

The production measures of bonsai are as follows:

First, Miaoyuan

The seedlings of bonsai of true pearl Luohan pine are usually obtained by artificial propagation techniques such as sowing and cutting. (the category of seed harvested is easy to plant, and we adopt the method of unisexual growth, both by cutting and raising seedlings.)

Second, modeling

Upper basin

Artemisia angustifolia is usually put on the basin before sprouting in the third spring, and the basin soil should use slightly acidic sandy loam with fluffy texture and good drainage. As the posture of rice leaf Luohan pine is simple and elegant, it is appropriate to choose purple sand basin or glazed pottery basin, and the shape of the basin is determined by the shape of the tree.

Modeling

The styling of Miye Luohan pine is mostly carried out in the dormant period, mainly in Panzha, supplemented by pruning. Due to the soft branches of Artemisia angustifolia, it is convenient for banding and pruning, so it has various shapes. The common situations 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.

Maintenance

The main results are as follows: (1) Pinus elliottii should be placed in a place with moist and fluent air in summer and indoor 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 Siraitia grosvenorii should be watered frequently in the development season, and the soil in the basin should be wet, but the basin should not be watered. In summer, often to the leaf or ground fountain, can connect the leaf color is bright.

(3) Sasa (special fertilizer for Siraitia grosvenorii) is prepared after long-term research and discussion. Sanchun should be applied twice (special fertilizer for Siraitia grosvenorii). Use 3 bottles of water to dilute the roots of Siraitia grosvenorii at 1:50, or with other flower fertilizers, the molded Siraitia grosvenorii should not be applied too much. After the beginning of autumn, there is no more giving.

⑷ pruning of Siraitia grosvenorii should be pruned frequently to connect the tree. When blooming, it is best to dispel the buds in time to avoid wasting nutrition. ⑸ turns the basin usually turns the basin every 2-3 years. Individual cases are carried out from March to April. ⑹ pest control should pay attention to the prevention and control of diseases and insect pests, especially in summer and high temperature seasons, we should pay attention to the control of shell insects and red spiders available (rice leaf Luo Han pine diseases and insect pests) 1 big 3 bottles into the solubilizer to add water diluted at 1:50 to spray on the leaves of rice leaf Luo Han pine), or with other floral medicine in the month before the mildew and rain festival, once every 10 days for 3 times, camellias can play the control consequences. After the use of medicine, it is best to wash your hands, let alone import.

The ability of resistance to diseases and insect pests is strong, cold resistance is weak, like to live in loose, fertile and well-drained sandy soil.

It can be propagated by sowing, cutting and grafting. The cutting time is carried out in the mid-March or June-July plum rain season in early spring, the shortest cutting time is only one leaf, the seedling bed needs shade or completely closed cutting, the tender wood cutting is easy to take root and the survival rate is very high. 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 from March to April in early spring.

Bonsai Culture method of Luohansong

(1) Environment: Pinus elliottii is a subtropical tree species, which produces in the Yangtze River Basin and other provinces and regions in the south. Like semi-shade, it is well preserved in warm, humid, fertile and loose, well-drained slightly acidic sandy soil, and is only suitable for potted plants in colder areas.

(2) Illumination: mature Pinus elliottii is beneficial to the leaf shape of the tree under strong light, so it can be shaded without shade, but the seedlings are young and should not be exposed to strong light for a long time. It should be maintained under the shade net or the sun will be moved to the shade after a period of direct sunlight.

(3) watering: Luohansong is not tolerant to drought, so in its growth period, we should pay attention to often watering potted plants, but not waterlogging. In summer, when the temperature is high, water should be watered in the morning and evening, and often spray water on the leaves to make the leaves bright green. It is rainy in summer in the south, and the rainy season is longer, so when you put it outdoors, you should pay attention to avoid stagnant water.

(4) fertilizing: the growth of Luohansong needs fertile soil, so fertilization is a very important link. The principle of fertilization is to apply thin fertilizer diligently. The fertilizer is mainly nitrogen fertilizer, properly added black alum, retted into fertilizer and water, and then fertilized. Fertilizing once in 1-2 months in the growing period, fertilization and watering can be carried out together, and the ratio of water and fertilizer is 9:1.

(5) Prevention and control of diseases and insect pests: diseases and insect pests of Luohan pine mainly occur in summer (May-September). It is necessary to beware of red spiders absorbing juice on the leaves in the form of various mites. The injured leaves will appear many small pink-green mottles, which will turn gray-white later. In this case, just buy some pesticides, such as phenybutyltin, pyridaben and so on. Spraying every 10 days can kill pests.
