Dendrobium cultivation methods, cultivation techniques and methods of Dendrobium

The planting method of Dendrobium is as follows:

The cultivation technology of Dendrobium pays attention to the cultivation environment, and the cultivation method is germination and sowing.

1. Technology: Dendrobium officinale cultivation is required to be carried out in the greenhouse, and the construction of the greenhouse requires ventilation, shade and rain protection, and insect nets, and according to the growth habit of renting Dendrobium officinalis, consider the natural factors such as light, temperature, humidity and ventilation of the site; The suitable temperature for the growth of Dendrobium officinale is 15 30, Dendrobium officinale requires to keep the substrate moist, and the air humidity is kept above 80% as good, but it can not accumulate water, and it is best to use sprinkler irrigation or drip irrigation when watering, and it is not allowed to irrigate.

2. Method: Soak the seeds in Wennian water for 3 hours, and then put them on the culture soil of the greenhouse for 3 4 days, keep the temperature at about 20 degrees, and germinate in about 4 5 days. The biological characteristics of Dendrobium officinale require that the cultivation substrate have good water retention and ventilation, and large-scale production requires that the raw materials of the cultivation substrate are easy to obtain and easy to operate.

Maintenance methods of dendrobium

Dendrobium prefers a humid environment, but it should not be watered too much, so as not to cause water and rotten roots. When watering, it is best to spray the whole plant with moisture to allow the plant to absorb the water sufficiently. There is no specific number of times to water Dendrobium, as long as the soil is moist.

Watering can be reduced appropriately when it is cold in winter. During the growth period of dendrobium, it is necessary to apply the fertilizer water of the rotted thin cake every 7-10 days, and the fertilizer can not be applied during the dormant period in winter.

Dendrobium prefers a semi-shady environment, and needs to be shaded by 60 -70 in spring and summer when the sun is strong; During the winter dormant period, more light is needed and should be shaded for 20-30 years. The suitable temperature for the growth of Dendrobium is between 15-30 degrees Celsius, and the temperature temperature in winter is best not lower than 5 degrees Celsius, and the temperature difference between day and night is best not to exceed 15 degrees Celsius. Dendrobium is native to tropical rainforests and prefers humid environments.

It is best to keep the humidity above 60 and not above 90 to avoid pests and diseases.

Cultivation techniques and methods of Dendrobium:

1. Prepare the soil: Dendrobium has high requirements for the soil, and it is necessary to prepare the soil to adapt to the planting, and it must ensure that it is soft, breathable, has strong drainage ability and is rich in humus, so that the soil environment can grow more vigorously. It can be mixed with peanut shells, wood chips, moss, moss, etc., or a special substrate for dendrobium can also be purchased.

2. Treatment of plants: whether it is the purchased Dendrobium seedlings or the Dendrobium seedlings dug by themselves, they must be specially treated before planting, and the dry and yellowed parts on the top should be cut off, and if there are rotten roots and dead roots, they should also be disposed of, so that they can better absorb fertilizer and water in the later stage and promote the recovery of growth as soon as possible.

3. Planting in the soil: the substrate is prepared, and the plants can be planted in the soil after they are treated. Put part of the substrate in the pot first, then put the plant, slowly fill the soil and compact, after planting, you need to water it in time, so that the root system and the substrate are tightly combined, so that it can resume normal growth as soon as possible.

Note that it should be placed in a warm, well-ventilated and cool environment.

The method of propagation of Dendrobium.

1. Cuttings propagation: choose May to June for cuttings. Cuttings are cut from three-year-old, robust plants, with full stems and 4 to 5 segments each.

The substrate is pure river sand. Insert the treated stem directly into the river sand and wait for the bud spots on the stem to grow before transplanting.

2. Dividing propagation: Dividing is also selected in spring, selecting healthy Dendrobium, cutting the biennial stem, removing the old roots, and then planting directly separately.

Cultivation environment, when cultivating dendrobium, it is necessary to choose a semi-shaded and sunny environment, and the room temperature needs to be controlled above 0 in winter; The choice of soil can be made by mixing bark, fern roots, and sand and gravel into a substrate for cultivation; Dividing propagation, which can be used in spring every year, it is necessary to select robust seedlings and plant them from the roots into the soil; Transplanting and maintenance, after Dendrobium takes root, it can be directly transplanted into the soil, and the diluted potassium dihydrogen sulfate solution is applied every half month.

Dendrobium has a certain resistance to negativity, suitable for growing in a semi-yin to sunny environment, the air humidity of the growth environment needs to be controlled at about 80%, and the room temperature pants sedan needs to be controlled above 0 in winter. When the light is too strong, it is necessary to take shading measures to avoid burning the leaves and affecting the normal growth of Dendrobium.

When planting Dendrobium, it is necessary to choose a suitable pot according to the size of the plant, and mix the bark, fern roots, sand and gravel, moss and pine bark into a cultivation substrate to ensure that the soil has strong air permeability and drainage, so that the root system of Dendrobium can breathe better, thereby improving the yield and quality.

Dendrobium can generally be propagated by the method of dividing, and the dividing can be carried out in spring every year, during which the air humidity is high, and the branches can resume growth as soon as possible after dividing. To divide the plants, select a sturdy and disease-free seedling, break it from the rhizome, and plant it in the soil with a root system.

After a few weeks, the seedlings will grow, and after the seedlings have grown, they can be transplanted into the soil. Note that the soil needs to be in a moist state during the growth period of Dendrobium. And apply the diluted potassium dihydrogen sulfate solution every half month.

Dendrobium can be harvested after 2 to 3 years of transplanting.
