What are the cultivation points of crab claw orchid? How to cultivate crab claw orchid

Crab claw orchid, a perennial flowering plant of the cactus family, blooms from November to January of the following year, and the single flower can open for up to a week, and the group can enjoy it for more than a month. It is a flower that has been popular for many years and is suitable for winter ornamentation. There are more than 200 varieties in the world, and the colors and patterns are extremely rich.

The key points to pay attention to in cultivating crab claw orchid are as follows: The cultivation substrate is mainly loose peat with good aggregate structure. It is suitable to be placed in a warm and humid environment, but the potting soil can not be too wet, and the principle of "dry and watering" is pursued, and the high temperature season can be watered once every 2 3 days, and watering at noon is avoided; Low temperature in winter, can be watered once a week; Do not water in the evening.

Thin fertilizer is applied frequently. After 30 days of cuttings, new leaves can be fertilized as they emerge. The EC value is.

It likes potassium fertilizer, followed by nitrogen fertilizer and phosphate fertilizer. The ratio of N, P and K fertilizers is 30 15 20 or 40 20 30. Stop fertilizing in winter, and in order to improve the flowering rate, you can spray 1000 times potassium dihydrogen phosphate liquid fertilizer once a week.

The suitable temperature for growth is 20 25, reaching 22 or more, and it is best to use ventilation equipment. Above 35 or below 2 will stop growing. The relative humidity should not exceed 75%.

In order to obtain a good plant shape, when the plant has more than 3 4 stem nodes, it is necessary to shape the plant and remove all the leaves above the 3 4 stem nodes in the lower part. Short-day treatment was applied one week after the plants were set. Flower bud formation can be seen in 3 weeks.

Flowering control. Crab claw orchid is a short-day plant, and the purpose of controlling the flowering period can be achieved by adjusting the light time. To promote flowering, start short-day treatment 60-70 days in advance of the desired flowering time.

8 hours of natural light per day, and the rest of the time is shaded. The light intensity inside the shading net should not exceed 5 lux. Do not exceed 25 temperatures.

Note that shading should be carried out continuously, without interruption in between. Flower buds can usually be seen after 20 days. Flowering is inhibited, and the natural flowering period of crab claw orchid is in November and December.

If you want to bloom during the Spring Festival, you need to take steps to delay the flowering period. Long-day treatment is generally carried out in mid to late September. Hours of light are given from 11 p.m. to 1:30 a.m. to break the darkness.

60 watt incandescent lamps can be installed in the shed, one per meter, and the distance from the plant is 90 cm.

The soil used to cultivate the plant must have good porosity and drainage, and you can use humus and a small amount of charcoal mud mixed with some sandy soil to prepare soil for the plant, only if the soil is fertile enough, the plant can grow well.

You must be careful when watering the plants, the plants are not afraid of drying, and the most afraid of watering too much will waterlog the plants. Plants are succulent, so watering must not be too much, otherwise it will inhibit root respiration and rot the rhizome. In addition, when watering, do not sprinkle water on the buds of the plant, otherwise the buds of the plant will fall off and cannot bloom.

Watering can be increased appropriately in summer, and watering is generally done once a week in winter.

The plant does not need much sunlight to receive every day, and the sunlight it receives every day is timed, and the plant should be shaded and protected from direct sunlight in summer. The temperature of the plant breeding environment is generally about 22 degrees.

If you want the plant to grow well, you need to fertilize the plant frequently, and you can apply it to the plant once every two weeks or so during the vigorous growth period, and you don't need to fertilize the plant when the temperature is too high or too low.

After propagation, the new branches can be cultivated in 12 cm ordinary plastic pots or hanging pots, and 3 plants can be planted in each pot. After planting, the indoor should be kept ventilated and cool, the temperature is too high or the air is dry, which is not conducive to the growth of stem nodes, and sometimes stem nodes shrink and die. Fertilization is applied once every half month during the growing season.

In autumn, apply 1 2 times of phosphorus and potassium fertilizer. Grafting new branches, when watering and fertilizing, pay attention not to splash the grafted healing place to avoid rot.

Crab claw orchid is a short-day plant that likes warmth and avoids high temperatures, and when flowering, the room temperature should not be high, and 10 15 is appropriate. Fertilization adopts the principle of combining ground fertilization and foliar spraying, and nitrogen and potassium fertilizers are the main fertilizers. Around September, potassium dihydrogen phosphate was added.

With normal maintenance, it can bloom 20 30 flowers in that year, and hundreds of flowers can bloom in one pot after 2 to 3 years of cultivation. The flowering period can last for 2 to 3 months, and the single flower generally blooms for 1 week before withering. Do not move it casually during the flowering period to avoid breaking the stem and falling the flowers.

If there is a generally short dormant state after flowering, watering should be controlled, fertilization should be stopped, and normal fertilizer and water management should be carried out after the stem nodes grow new shoots. If the amount of watering after flowering is too large, the root system is easy to rot, and the stem nodes will shrink and die. If crab claw orchid needs to bloom and market in advance, it can be treated with short-day light, and 8 hours of short-day shading treatment every day can bloom one month earlier and enter the market.

Soil cultivation Soil cultivation requires the use of loose humus soil. Before planting, peel off the dry bulb pieces on the surface of the daffodil, scrape off the old roots, and add humus to 3 cm along the pot. Hold the pot with both hands and shake it to make the humus compact, then place the daffodil bulb disc in the pot, and then continue to add soil about 1 cm, then water thoroughly, and then put the pot in a cool place, 5 days later, after the bulb disc grows roots, put the pot in a sunny place to breed.

Soil watering should pay attention to see dry and wet, that is, the soil is not dry and not watering, once watered, it should be watered until the bottom of the pot leaks, and the watering time should be selected in the morning and evening, otherwise it will destroy the growth of the roots.
