Soil, environment and temperature are the key to the planting requirements of Dendrobium candidum.

Soil quality requirements: peat, fern root and bark are selected as transplanting substrates. Temperature requirements: the suitable temperature for growth is 12-35 ℃. Lighting requirements: suitable for growth in damp, ventilated, half-yin and half-yang environment, avoid direct sunlight in summer. Humidity requirements: humidity should be kept above 60%. Water spraying density: once a month in winter, once a week in spring and autumn, and once a week in summer. Water quality requirements: use neutral water or slightly acidic water.

I. soil quality requirements

The main results are as follows: 1. Dendrobium candidum can not be planted in the soil, mainly because Dendrobium candidum is aerial root and shallow root, that is to say, it requires good air permeability, which is generally modeled on the growth environment of Dendrobium candidum in the wild state. if you choose stone as the matrix, the air permeability will be better, but the water retention will be poor.

2. It can be seen that a single substrate is difficult to meet the conditions of water retention and air permeability at the same time, so the substrate for artificial planting of Dendrobium candidum should be loose and permeable, not easy to mildew, good drainage, no bacteria and no pests. Peat, water moss, rock, shavings, fern roots, bark, board edges, fungus bran and wood bran can be selected as transplanting substrates.

Second, temperature requirements

The survival temperature of Dendrobium candidum is-10 ℃, and the suitable temperature for growth is 12-35 ℃. When the temperature is high in summer, shading and ventilation are needed in the greenhouse, and spray is often used to keep moisture and cool down. When the temperature is low in winter, heat preservation is needed.

Third, lighting requirements

1. Dendrobium candidum is a semi-humid plant, generally wild Dendrobium candidum is epiphytic on rocky cliffs at higher elevations, or on the epidermis of trees in a humid environment, because these epiphytic bodies (rock, bark) have little water, and some even have no water (rock).

2. Dendrobium candidum belongs to aerial root plant, which mainly obtains nutrition by absorbing water and nutrients in the air. These factors determine that Dendrobium candidum needs to be planted in a humid, ventilated, half-yin and half-yang environment.

3. The primary environment of Dendrobium candidum is in the shade and shade, so the planting environment needs proper shading, shading when the sun is strong, to prevent direct sunlight, shade can be built.

IV. Humidity requirements

In the growth process of Dendrobium candidum, it is necessary to be equipped with a hygrometer, which can keep the humidity above 60%. In case of overcast and rainy weather, the humidity is above 90%, so it is necessary to strengthen ventilation to avoid the occurrence of bacterial and fungal diseases.

Fifth, spray water density

It needs to be watered every one month in winter, every two weeks in spring and autumn, and every other week in summer.

VI. Water quality requirements

When watering should spray frequently, less drenched, usually need to wait until the matrix is dry and then drenched, the water quality needs to use neutral water or weak acidic water.

7. Prevention of insect pests

Dendrobium candidum has fewer diseases and insect pests, generally in the case of good ventilation, there is no need for special drug control, if insect pests occur, they need to be dealt with according to the specific situation.

VIII. Fertilizer requirements

Fertilization requires frequent application of thin fertilizer, do not use heavy fertilizer, otherwise it is easy to cause fertilizer damage.

IX. Ventilation requirements

Ventilation and ventilation are also important to the roots in the matrix, so it is recommended to choose materials with good permeability, and must be watered thoroughly to bring fresh air into the matrix. The air is very important to Dendrobium candidum and can reduce the occurrence of diseases at the same time.
