Cultivation method of white orchid 1 Soil: White orchids like acidic soil, and the requirement for soil pH value is 5.5-6.3. It is best to use fertile, loose and well-drained culture soil. It can be prepared with 5 parts of pine needle humus soil, 2 parts of coarse bran ash, 2 parts of coarse sand and cooked manure 1 part, and it is forbidden to use fine sand or cohesive soil with poor air permeability.

2. Sunshine: Magnolia is a sunny flower and needs plenty of sunshine. During its growth period, it should be maintained on the sunny ground with long sunshine time and strong sunlight, especially in flowering period. The daily light shall not be less than 6 hours. If it is maintained in a cool place, only long leaves will not bloom, or there will be few flowers, slender branches, light leaves, thin leaves and dark leaves, which is not good for growth. However, direct sunlight should be avoided in summer, and shade should be given from 9 am to 4 pm. At the same time, water should be sprayed on the leaves and the ground to increase the air humidity.

3, temperature: white orchids like cold and warm, we should pay special attention to protection, so that it can safely overwinter. Generally, we should move indoors at the end of 5438+ 10 and put it in a sunny place. The room temperature should be kept around 10℃ and should not be lower than 5℃.

4, watering: white orchids are fleshy roots, the pot soil is too wet, the leaves will wither and fall off, and even the roots will die. If they are too dry, they will dry up and roll up the leaves. They are flowers that are afraid of both waterlogging and drought. At the flowering stage, the petals are excessively stretched, indicating that the water is insufficient, and when the water is suitable, it is bud-shaped. When the soil surface is dry and the soil is hard and cracked, it should be watered immediately. When watering, the water temperature and soil temperature must be consistent, and cold water or hot water cannot be poured suddenly. Generally, water 1 time every day in spring and autumn. In summer, the weather is hot, the evaporation is large, and the growth is vigorous. The watering frequency and weight can be appropriately increased. When you are indoors in winter, you should control the water.

5. Fertilization: White orchids have a long flowering period and like fertilizer. If there is not enough fertilizer, they will bloom less. Improper fertilization will lead to excessive branches and leaves and poor flowering. 2. Before the new buds germinate in March, apply decomposed cake fertilizer as base fertilizer. At flowering stage, dilute human excrement or urine, or 9 portions of bean cake, tea seed cake and fish bone fermented liquid fertilizer are mixed with water, and applied every 3-4 days 1 time. Stop fertilizing half a month before entering the room for wintering.

6. Pruning: During the growth of white orchids, plants should be pruned, diseased dead branches and overgrown branches should be cut off, and some lower leaves should be removed to inhibit the growth of plants and promote the flowering of pregnant buds.

Growth habit of white orchid

1, Habit: White orchid likes light, is afraid of high temperature, is not cold-resistant, and is suitable for slightly acidic soil. Like warm and humid, not resistant to drought and flood, sensitive to toxic gases such as sulfur dioxide and chlorine, and poor resistance.

2. Propagation: The propagation methods of white orchids include grafting, layering, sowing and cutting. Grafting and layering are used more than sowing and cutting, but grafting and layering are enough for family farming.
