Culture method of Japanese Luohansong

Japanese Luo Han pine posture is graceful and elegant, the leaf is small and thick green, not only can be planted alone or group, but also suitable for hedgerow or bonsai material, high ornamental value, planting around the villa can be a combination of high ornamental and high-grade, coupled with some lighter green flowers and plants, very simply become a beautiful scenery, let's take a look at the breeding methods of Japanese Luohansong!

Growth habits of Japanese Pine Pine

The crown of Japanese Luohan pine is broadly ovate, leaf-shaped lanceolate, dioecious or occasionally monoecious, and the seeds are ovate on a fleshy and inflated receptacle, flowering and fruiting in October. Sexual preference for warm, moist, semi-shady environment, strong adaptability, can grow freely in the hot sun, strong resistance to diseases and insect pests, cold tolerance is weak, like to be born in loose, fertile and well-drained sandy soil.

The Propagation method of Japanese Pine

1. Seed propagation: harvest and storage before the pulp becomes red and the fruit falls naturally, shake the trees to collect the fallen fruit, and the naturally fallen fruit can also be used. The picked fruit can not be dried and sowed immediately. If you want to wait until the beginning of the next spring, you can only wash the pulp and bury it in the wet sand to keep it moist.

2. Cutting propagation: in the middle of May, using the branches of last year, cut off the branches with a length of 10 cm, and retain about 5 leaves to soak in water for 2 to 3 hours. When cutting, it should be a little deeper, 2 or 3 leaves can be buried in the soil, and then covered with plastic film. Pay attention to the sun and remove the plastic film in mid-late September.

Culture method of Japanese Luohansong

1, rational fertilization: Japanese Luohansong like fertilizer, should be thin fertilizer frequently, fertilizer is mainly nitrogen fertilizer, can add appropriate amount of black alum, retting into alum fertilizer water. Fertilization can be applied once every two months during the growing period, and fertilization can be combined with watering at the same time. The method of semi-orchard ditch application can be used for planting in a large area, and the fast-soluble compound fertilizer is 300g to 500g each time. Potted plants can be sprayed with 0.5% water fertilizer or 1.0% water fertilizer or thin cake liquid water fertilizer each time.

2. Light management: Japanese Pinus elliottii is a neutral and partial negative tree species, which can accept strong light and 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 Japanese pine tree is propitious to maintain its leaf shape under the condition of high temperature and strong light. Because the tissue is young, the seedlings should not be exposed to strong light for a long time, so it is recommended to keep them in the shade of trees.

3. Water management: Luohansong is not a plant of Pinaceae and is not resistant to drought, on the contrary, it is resistant to shade and dampness. It should be watered frequently during the growing period, but it should not be watered. Pay attention to regular watering on sunny days 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 and is not resistant to waterlogging, so we should pay attention to prevent water accumulation for a long time.

4. Pest control: Japanese Luohan pine is often harmed by leaf spot disease and coal fouling disease. Leaf spot disease can be sprayed with more than 50% carbendazim or 600 times 800 times of thiophanate wettable powder, and coal pollution disease can be irrigated with soapy water or clear water. Common pests are coir moth, shell insects, white wax insects, etc., which can be sprayed with 1000 times of omethoate emulsion or 1000 times of dichlorvos emulsion.

Note: family potted Japanese pine 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. Growing season moisture can be slightly more, hot summer basin soil dry should be timely watering, watering should be fully watered, autumn and winter moisture 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.
