The latest culture method of dipper orchid

Cypripedium is also known as the flower of the goddess. Cypripedium is a perennial herb belonging to Orchidaceae. It has high ornamental value. It not only has beautiful flowers with peculiar beauty, but also has elegant leaves. It has very good cold resistance and is suitable for garden cultivation in cool areas. Let's take a look at the cultivation methods of Cypripedium together.

The growth habits of Cypripedium

Cypripedium likes cool, moist and semi-shady environment in summer, suitable for fertile and loose sandy loam growth. Like wet, watering in the growth period should be 1~2 times a day, so that the basin soil and basin surface moss fully moist, in order to play a role in moisturizing and cooling. Shading should be about 50~60%, otherwise too much shade will make the plant grow weak. Fertilization should be applied once a month during the growth period, and it should be diluted more than 1000 times before it can be applied. Otherwise, thick fertilizer will hurt the plants and cause the rhizomes to rot and die.

The breeding method of Cypripedium

Cypripedium is often propagated by dividing plants, which can be carried out in spring and autumn, generally dividing plants once every three years. Where the plants grow strong, pseudo-corm dense can be divided into plants, after dividing plants, each cluster should keep at least 5 pseudo-corms connected together. Reduce irrigation before splitting plants to make pot soil compare. When the plants are placed in the pot, cover the bottom holes with broken tiles first, then spread coarse stones, accounting for 1/5 to 1/4 of the pot depth, then put coarse soil and a small amount of fine soil, and then plant with sandy loam rich in humus. The planting depth is to bury the false bulb just into the soil, leave 2 cm along the edge of the pot, spread with green grass or fine stones, and finally irrigate with water, place in the shade for 10~15 days, keep the soil moist, gradually reduce watering, and carry out normal maintenance.

Cultivation method of Cypripedium

1. Pot soil: The upper pot time of Cypripedium is generally from March to April in spring or October to November in autumn. For ventilation requirements, the application of pots with plain burning pots is better, plastic pots and colored glaze pots due to poor ventilation, not suitable for cultivation of Cypripedium pots. The best soil to be used is the one collected from the original site, or the culture soil prepared with 0.5 parts coarse sand, 1 part humus soil, 0.5 parts pearlite and 1 part peat soil.

2. Upper basin: Before putting Cypripedium orchid into the basin, cut off the old leaves beside the new buds first, and remove the black and rotten roots, then lay the orchid plants with whole roots flat on the surface paved with about 1/4 of the subsoil, evenly fill the basin with soil until the roots are all buried, only the new buds protrude, and finally cover the basin surface with white moss saturated with water, and complete after watering thoroughly.

3. Watering: Once water shortage occurs during the peak growth period of Cypripedium, it will grow poorly, requiring eight minutes dry and two minutes wet. Watering should be based on the principle of "watering dry, stopping wet, properly dry". Water must be poured thoroughly, not half water. The number of watering can be determined by the planting material of the potted orchid. Such as volcanic stone, red brick particles, floating stone and other hard hydrophobic plant materials, water can be supplied once a day. Pond mud, humus and other strong absorbent plant materials, water supply can be two or three days a time.

4, temperature: Cypripedium daily management mainly pay attention to the temperature, usually 10~20℃, once the temperature exceeds 25℃ to try to lower the temperature, otherwise it is easy to die of heat. Therefore, if it is to be cultivated in most parts of the south or north of China, it is impossible to successfully cultivate it, let alone bloom, unless there is a cooled greenhouse in summer.

5. Illumination: Cypripedium likes shade and is afraid of direct sunlight. Shading should be carried out in spring, summer and autumn. Family breeding is best placed on balcony windowsill or under eaves with bamboo curtain shading. Generally, shade is carried out before 9 a.m. to 6 p.m., and the curtain is opened in the morning and after 6 p.m. to make it accept scattered sunlight. In winter, it should be moved indoors to visible scattered light, but direct sunlight should also be avoided.

6, fertilization: Cypripedium in the growing season can be fully decomposed about 15% thin cake fertilizer water, or 0.1% urea fertilizer water plus 0.2% potassium dihydrogen phosphate water, every 15~20 days, before flowering to flowering can be sprayed to the foliage 2~3 times 0.2% potassium dihydrogen phosphate or plant ash water, to promote the development of roots, stems and flowers. Do not apply undecomposed fertilizer to avoid root rot.

Control of Diseases and Pests of Cypripedium

1. sheath rust: usually on the upper and lower surfaces of leaves, less raised blisters on stems, containing yellow, orange, rust or even purple-black powdery spores. Rust does not kill, leaves do not die, but it weakens plant growth. The control method is to cut off the diseased leaves, and spray 65% Zineb powder 500~600 times or copper-containing fungicide.

2, white silk disease: sheath rust occurs mostly in the rainy season. At the beginning of the disease, the leaf base was covered with white threads. Causing the rhizome to rot. The control method is to drop the soil with bacteria and sprinkle pentachloronitrobenzene powder or lime. The radical cure method is to pay attention to ventilation and light transmission, and the basin soil drainage is good. Seriously sick plants burn.

3, anthrax: all year round, high temperature and rainy season is more rampant. The disease spots extend from leaf tip to rhizome, brown at first, then gradually expand and increase, many dry black spots appear, and serious cause death of the whole plant. In addition to actively improving environmental conditions, 50% thiophanate-methyl WP 800~1500 times solution can be sprayed once every 7~10 days, and then supplemented with 1% equivalent Bordeaux solution once every half month, continuously spraying 3~5 times.

4. Scale insects: Scale insects are the general term of Homoptera scale insects, which reproduce fastest under high temperature and humidity and poor air flow. It can be sprayed with 1% omethoate or 1500 times 50% mala sulfur during incubation period. If the number of pots is not much, it can also be manually brushed.
