Planting method

The roots of orchids are fleshy roots, which store a lot of water.

The characteristic of this kind of root is that it is afraid of stagnant water and likes ventilation and drought resistance. When choosing pots, it is necessary to be conducive to the ventilation, ventilation and drainage of planting materials, and also to consider factors such as aesthetics. Commonly used blue pots are plastic pots, porcelain pots, plain-fired pottery pots and purple sand pots. Plastic pots are light and have good water retention, but they don't absorb water. Poor air permeability and heat dissipation. The plain burning basin has good air permeability and moderate price, but its appearance is rough. Purple sand basin has good air permeability and beautiful shape, so it should be selected as needed. Most of them use thin and tall planting pots, which can keep the air permeability of orchid roots and is beneficial to the growth of orchid roots. It is best to choose the same specifications for the same blue room, so that the air permeability is basically the same and the humidity is easy to master.

A large number of non-granular planting materials are used in traditional orchid cultivation, which easily leads to orchid hardening, water accumulation and root rot, which increases the management difficulty. In order to increase ventilation and avoid root rot, the advanced mixed substrate cultivation method is adopted, which is loose, breathable and has good water retention, which solves the problem of root rot well. Planting substrates include: pond cornerstone, vermiculite, phytosilica, perlite, Emei fairy soil, etc. , mix as needed. Firstly, dust is removed, and then three kinds of particles, large, medium and small, are separated by different sieves, soaked and dried for later use. [3]

liquid manure

Orchid water should be slightly acidic to neutral (pH 5.5-6.8). Rain is the best, followed by spring water, river water and tap water. The temperature in spring is low, orchids have not yet begun to grow, and the amount of watering should be less; Orchids grow vigorously in summer and autumn, and the amount of watering should be more; When the weather turns cold in autumn, it is necessary to reduce water use; Dormancy in winter, low temperature, less watering times and less water. Spring and winter should be watered at noon, and summer and autumn should be watered in the morning or evening. Avoid pouring tap water at noon in summer.

It is advisable to master the principle of applying light fertilizer regularly. The temperature 15-30℃ is most suitable for fertilization in sunny days, but not in rainy days. Organic fertilizer should be fully decomposed before application, and chemical fertilizer should be sprayed on the leaves, with the concentration controlled between 0. 1%-0.3%.

Lighting temperature

Orchids should be shaded except in early spring and winter. In summer and autumn, about 70% sunlight should be blocked from 9 am to 4 pm. Pay attention to rain protection in case of continuous rain or rainstorm. After the sultry thunderstorm, it should be thoroughly watered with clear water. When the temperature drops to 2-3℃ in late autumn, you should enter the room in time.

Plastic trimming

Cut off dead leaves and diseased leaves at any time, and pay attention to the disinfection of tools when cutting. After the flower buds are unearthed, if there are too many, the weak buds should be removed and the strong buds should be kept. When plants are not growing well, flowers should be picked.

Spray humidification

In the dry season, it is best to install an automatic sprayer to spray to cool down and increase humidity.
