Cultivation method of Cypripedium

The dipper orchid, also known as the flower of the goddess, is a perennial herb of the orchid family, which has extremely high ornamental value. It not only has gorgeous flowers full of peculiar beauty, but also the posture of the leaves is very elegant, and it is very cold-resistant. It is suitable for garden cultivation in cool areas. Let's take a look at the cultivation methods of dipper orchids.

Growth habits of Dipper Cymbidium

The dipper orchid likes the cool, humid and semi-shady environment in summer, which is suitable for the growth of fertile and loose sandy loam soil. Like dampness, watering should be done twice a day during the growing period, so that the basin soil and basin water moss are fully moist, so as to protect moisture and cool down. Shading needs about 50% 60%, otherwise overshading will make the plant grow weak. Fertilization is about once a month during the growing period, and it should be diluted more than 1000 times before it can be applied, otherwise the thick fertilizer will hurt the plant and cause the rhizome to rot and die.

Propagation methods of Dipper Cymbidium

The dipper orchid is often propagated by the split method, which can be carried out in both spring and autumn, usually every three years. All plants with strong growth and dense pseudocorms can be ramified, and at least 5 connected pseudocorms should be preserved in each clump after ramet. Irrigation should be reduced before splitting, so that the basin soil is better than. When putting on the basin after ramet, first cover the bottom hole of the basin with broken tiles, then cover with coarse stones, occupy the depth of the basin from 5 to 1, and then put coarse-grained soil and a small amount of fine soil, and then plant it with sandy loam rich in humus. Planting depth to the false bulb just buried in the soil strength, the edge of the basin left 2 cm along the mouth, covered with green cloud grass or fine stones, and finally watered thoroughly, placed in the shade for 10-15 days, keep the soil moist, gradually reduce watering, and carry out normal maintenance.

Culture methods of Dipper Cymbidium

1. Potted soil: the potting time of dipper orchid is generally from March to April in spring or from October to November in autumn. In order to meet the requirements of ventilation and ventilation, the plain burning basin is better for the application of pots, while plastic pots and colored glaze pots are not suitable for cultivating dipper orchids because of poor ventilation. It is best to use the soil collected from the original place, or the culture soil prepared by 0.5 part of coarse sand, 1 part of humus soil, 0.5 part of perlite and 1 part of peat soil.

2. On the basin: before putting on the basin, the old leaves next to the new buds should be cut off, and the blackened and rotten roots should be removed, then the orchid plant with the whole root should be laid flat on the surface covered with subsoil about 1cm 4, and the soil should be evenly filled into the basin until all the roots are buried and only the new buds will be prominent. finally, the basin will be covered with water-absorbing white moss and watered thoroughly.

3. Watering: once the dipper orchid is short of water in the peak growth period, it will grow poorly, requiring eight minutes of dry and two minutes of moisture. Watering should be in line with the principle of "dry is poured, wet is stopped, and properly dry". The water must be thoroughly watered, not half of it. The watering times can depend on the plant material of the pot orchid. Such as volcanic stone, red brick grains, pumice and other hard hydrophobic plants, can supply water once a day. Plants with strong water absorption, such as pond mud and humus, can be supplied once every two or three days.

4, temperature: the daily management of the dipper orchid mainly pays attention to the temperature, usually 10-20 ℃, once the temperature exceeds 25 ℃, we should try to lower the temperature, otherwise it is easy to be killed by heat. Therefore, if it is to be cultivated in most parts of the south or north of China, it can not be cultivated successfully, let alone bloom, unless there is a cooling greenhouse in summer.

5. Lighting: the dipper orchid likes shade and is afraid of strong light. Shading should be carried out in spring, summer and autumn. Family breeding had better be placed on the balcony and windowsill with bamboo curtain shade or under the eaves, generally from 9 am to 6 pm for shade. In the morning and after 6 pm, open the curtain to make it accept scattered sunlight. In winter, it should be moved to the place where the scattered light is visible indoors, but direct sunlight should also be avoided.

6. Fertilization: in the growing season, dipper orchid can apply about 15% fully mature thin cake fertilizer water, or 0.1% urea fertilizer water plus 0.2% potassium dihydrogen phosphate fertilizer water, once every 15 days. 0.2% potassium dihydrogen phosphate or plant ash water can be sprayed on the leaves for 2 times from pre-flowering to flowering stage to promote the development of roots, stems and flowers. Do not apply unripe fertilizer so as not to rot the roots.

Disease and pest control of dipper orchid

1. Sheath rust: usually on the upper and lower surface of the leaf, there are few protruding blisters on the stem, containing yellow, orange, rust, or even purplish-black powdery spores. Rust is not fatal and leaves do not die, but it weakens plant growth. In addition to cutting off the diseased leaves, the control method can be sprayed with 65% Dysen zinc powder 500-600 times or copper-containing fungicides.

2. White silk disease: sheath rust mostly occurs in mildew and rain season. At the beginning of the disease, the leaf base was covered with white silk. Causing the rhizome to rot. The control method is to drop the bacteria-carrying basin soil and sprinkle it with pentachloronitrobenzene powder or lime. The radical cure method is to pay attention to ventilation and light transmission, and the basin soil is well drained. Seriously diseased plants will be burned.

3. Anthrax: it occurs all the year round, especially in the high temperature and rainy season. The disease spot first extends from the leaf tip to the rhizome, which is brown at first, then gradually expands and increases, and many dry black spots appear, which in severe cases lead to the death of the whole plant. In addition to actively changing the environmental conditions of Bodhisattva, during the onset period, 50% methyl topiramate wettable powder 800-1500 times can be sprayed once every 7-10 days, and then supplemented with 1% equivalent Bordeaux solution, once every semimonthly, 3 times continuously.
