How to cultivate slipper orchids? Talking about the cultivation skills of bonsai slipper orchid

Slipper orchid is one of many orchids, which is different from other orchids when it blossoms, and its petals have gorgeous patterns and high ornamental value. the following editor will talk about the cultivation skills of bonsai slipper orchids. Bonsai slipper orchid method is very simple, first of all to master its growth habits, followed by management skills, the following is a detailed explanation, like the relatives to have a look.

one? Light

Slipper orchids are native to dark, damp woods, so avoid direct sunlight. During cultivation, 50% ~ 60% shade is suitable in spring and autumn, 70% ~ 80% in summer and 50% in winter. The requirement of light intensity of slipper orchid varies with different varieties. The original species of multi-flower type of green leaves prefer more light, and the suitable light intensity is about 32,400 lx, while the variegated leaf varieties are more suitable for cultivation in low light environment, and the suitable light intensity is about 10 800 ~ 21 600 lx [1]. Under suitable light, the plant grows healthily, the leaves are short and wide, the leaves are thick, the flowering rate is high, and the flowers are bright. If the light intensity is too weak, the photosynthesis efficiency is not high, the plant nutrition is insufficient, the plant is easy to grow, the leaf is slender, thin and soft, lack of luster, low flowering rate.

two? Temperature

The primary environment of slipper orchid is mostly in high altitude areas, which requires a large temperature difference between day and night. It is better to keep the daily temperature at 26 ~ 28 ℃ and night temperature at 17 ~ 20 ℃ in spring and autumn, and 28 ~ 30 ℃ and 20 ~ 22 ℃ at night in summer. Different kinds of slipper orchids have different adaptability to low temperature in winter. The non-variegated leaf system is the most cold-tolerant, and the lowest tolerable temperature is about 5 ~ 7 ℃, while the rest is above 10 ℃ [1,2].

three? Moisture content

Slipper orchids grow in wet areas, and the root system requires ventilation rather than dampness. Like Phalaenopsis, slipper orchid has no false bulb, and its drought resistance is far lower than that of Cymbidium and Oncidium. It is necessary to keep the substrate moist and high air humidity in the process of cultivation. When the surface of the substrate is slightly dry, it should be watered in time to keep the basin moist. Watering should be thoroughly watered so that water flows out from the bottom of the basin to remove water and air from the basin.

four? Fertilizer

Slipper orchid likes fertilizer, but its root is very sensitive to salt concentration, which is easy to lead to root decay due to salt accumulation. Liquid fertilizer, organic fertilizer and slow-release fertilizer can be used in daily management. From March to September, fertilizers with high nitrogen content should be selected, such as Huaduo 3 ∶ 1 ∶ 1 or 2 ∶ 1 ∶ 1, and fertilizers with more phosphorus and potassium should be applied after October, such as Huaduo 1 ∶ 3 ∶ 2 or 3 ∶ 15 ∶ 5. The concentration of solution was 2 000 ~ 4 000 times, once a week.

five? Matrix

Slipper orchids are mostly terrestrial orchids, and organic mixtures are used in cultivation media. Can use the mixture of water moss, broken fern root, bark, blue stone and so on. Gravel or bricks are used as substrates when planting, with a quantity of about 1 to 5, which is beneficial to ventilation and drainage.

six? Changing basin and ramet

After the flower fade, the pots and ramets can be changed in spring and autumn before the new roots grow. Slipper orchid does not have many roots, so be careful when changing pots and ramets, remove the old matrix and rotten roots, and fill the bottom of the basin with gravel or bricks to facilitate drainage. Place in a dark place within half a month after changing pots and ramets, spray water on the leaves many times a day, but keep the roots properly dry and wait for the new roots to grow before watering.

seven? Pest control

The common pests of slipper orchid are mites, shell insects, thrips, which can be controlled by avermectin, quick culling and other insecticides, once a week for 3 ~ 4 times. Slipper orchid diseases are relatively rare, but bacterial and fungal diseases are easy to occur in plum rain season and summer, which can be sprayed with mancozeb, carbendazim and agricultural streptomycin. Spray should be meticulous and considerate, and should be sprayed around the bench and flowerpot. It is necessary to adhere to the principle of "prevention first, comprehensive prevention and control", improve the environment, pay attention to hygiene, strengthen ventilation and light penetration, avoid high temperature and humidity, and remove residual branches and leaves and plants infected with diseases and insect pests in time.
