Crab claw orchid has strong resistance to electromagnetic radiation and radioactive substances, and also has a certain ability to absorb some harmful gases in the air. Below I will introduce to you the cultivation methods and techniques of crab claw orchid. Welcome to read.

1. Selection of flower pots for Crab Claw Orchid cultivation

1 Flower pot quality requirements: Clay flower pots, plastic pots, porcelain pots, and ceramic pots can be used, but clay pots should be used. Quality flower pots are better. In order to coordinate with the home decoration, it can be cultivated in plastic flower pots with changing colors.

2 Flower pot size: Crab claw orchid should be cultivated in a pot with a crown diameter of 2/3 pot diameter.

2. Pot soil preparation for crab claw orchid cultivation

Crab claw orchid likes fertile and loose soil.

The following formula can be used at home: garden soil: leaf humus soil: sand = 3:4:3; peat soil: leaf humus soil: sand: perlite or volcanic rock = 4:2:2:2. After the soil is prepared, it is best to sterilize it at high temperature before use, or it can also be sterilized by exposure to the sun.

3. Watering methods for crab claw orchid cultivation

1 Crab claw orchid likes moist soil and avoids moisture. After the leaf buds sprout in spring, you can gradually increase the amount of watering to keep the soil moist. When watering, you should pay attention to drying and moistening. Spring and autumn are the peak growth seasons for crab claw orchids. In addition to watering, you should also frequently sprinkle water around the plants to increase the air humidity.

2 When the temperature is high in summer, the growth of crab claw orchid will be stagnant if the water supply is not sufficient. Therefore, watering should be paid attention to in summer, but the pot soil should not be too wet to prevent the disease caused by high temperature and humidity. rot. However, attention should be paid to spraying around it several times a day and strengthening ventilation to achieve the purpose of humidification and cooling.

3 In late autumn, when the temperature gets cooler, pay attention to watering the wetland between dry and wet areas. When the temperature is low in winter and early spring, growth is slower and the pot soil should be kept in a dry state.

4. Fertilization method for crab claw orchid cultivation

1. Crab claw orchid likes fertilizer. When there is sufficient fertilizer, it will have many branches and flowers. Start topdressing after the leaf buds of crab claw orchid sprout. During the growing season, you can topdress with decomposed 10 times liquid fertilizer mixed with an equal amount of 1000 times potassium dihydrogen phosphate solution, or 1000 times "Huaduoduo" general fertilizer once every 15-20 days.

2 The frequency of fertilization should be reduced in late autumn, and fertilization should be stopped when the temperature is below 10°C. Do not fertilize when temperatures are higher in summer and lower in winter.

3. Fertilizer for crab claw orchid should be applied thinly and frequently, not thickly. When applying fertilizer, apply it slowly along the edge of the pot with a fine-mouth watering can. Do not splash the fertilizer liquid onto the leaves, otherwise it will easily burn them.

Environmental requirements for crab claw orchid cultivation

Temperature requirements

The flowering period of crab claw orchid coincides with the winter storage season. It is best to keep the indoor temperature around 15℃. It cannot be lower than 10℃, otherwise the buds will fall off easily, especially those using sky rulers as rootstocks are not cold-resistant. They grow vigorously at 23-37℃, grow slowly at 20℃, and stop growing at around 15℃, and the root system absorbs activities. reduce.

Light requirements

Crab claw orchid is a typical short-day plant, so every autumn when the days gradually shorten, it begins to bud, and it is necessary to create short-day conditions for it. At this time, it is best to It is best not to put it indoors with lights at night to ensure the short daylight conditions it needs to conceive buds.

In addition, special attention should be paid to maintenance during the flowering period of the buds. For example, the pot soil should not be too dry or too wet. Water should be sprayed frequently to moisten the flower buds and stems. Before flowering, apply more liquid fertilizer mainly phosphate fertilizer.

Daily management tips for Crab Claw Orchid cultivation

1. During the post-flowering dormancy period, the pot soil should be kept moderately dry, and spraying water on multiple leaves can relieve dormancy in advance;

2. The first prosperous pot soil should be kept moist for a long time, and the fertilizer should be sufficient. The fertilizer should be mainly nitrogen, supplemented by phosphorus and potassium. In autumn, phosphorus and potassium fertilizers should be used as the main fertilizer, supplemented by nitrogen, until flowering;

3. During the summer period, 70% of the sun should be blocked, fertilizer should be stopped, water should be controlled, water should be sprayed on multiple leaves, and direct rain should be avoided. Rain and dry heat should also prevent the danger of red spider mites.

The crab claw retains buds and promotes flowers

In autumn, the crab claw orchid enters its second vigorous period, and has the short-day conditions for flowering. In the early stage of growth, new stem nodes will continue to grow, and in the later stage, flower buds will differentiate and enter the budding stage. Since there is no clear boundary between the two alternating periods, in order to ensure flowering that year, the growth of stem nodes must be abandoned.

Give low light, keep dry without water or fertilizer, and only sprinkle a small amount of water on the leaves to prevent the flat stems from dehydrating and wilting. In late autumn, increase heat preservation measures and enter the greenhouse at the right time. Watering can only be done as appropriate until individual stem nodes are budding. After more than half of the stem nodes have budded, apply concentrated fertilizer twice at half-month intervals to ensure colorful flowers. Another technique for promoting flowering is also simple and easy to do. After autumn, the potted flowers that have oversummered will be slightly controlled in fertilizer and water, and short-day treatment will be carried out after mid-September. The lighting time is from 9 to 17 o'clock every day, and no light is allowed during the rest of the time. Buds can usually appear in two months. This treatment not only produces a large amount of flowers, but also greatly advances the flowering time.
