How to plant Dendrobium nobile? What is the planting method?

1. The container should choose a flowerpot with a larger diameter at the bottom or a hole around it, which requires good air permeability and good leachability.

2. The lower layer of the matrix is covered with larger stones or bricks to facilitate water drainage and ventilation, the middle layer is made of smaller stones or broken bricks, and the materials with better water absorption are selected as far as possible, such as ceramsite, blue stone and broken bricks, and fermented pine trees are used in the upper layer.

3. When planting Dendrobium, we should try not to bury the stem of the seedling into the substrate, which can cover most of the roots and water thoroughly after planting.

4. fertilize the orchid special slow-release fertilizer around the root of Dendrobium, then cover it with a small amount of bark and water it again.

5. After planting, put the tin pot in a well-ventilated, semi-shaded environment, such as a well-lit windowsill, a balcony without direct sunlight or a sunshade.

Note: when the environment of potted Dendrobium is open, it is necessary to place Dendrobium all the time under the balcony big-leaf plants, which block too much light. Growers usually only water and have not been hit with pesticides, and fertilizer is a slow-release fertilizer added when planting. Later, add some Haokangduo fertilizer. The new buds of Dendrobium grew rapidly in overcast and rainy weather, and grew slowly when the temperature was high and the humidity was low in sunny days. The usual management is to water it several times a day on a sunny day.

2. The efficacy and function of Dendrobium nobile

1. Anti-aging, improve immunity

Dendrobium nobile can significantly increase the level of superoxide dismutase (SOD), reduce lipid peroxidation (LPO), regulate the level of monoamine neurotransmitters in the brain, inhibit monoamine oxidase (MAO), and delay aging. Dendrobium polysaccharide, which has attracted much attention in recent years, also has significant immune enhancement activity and anti-aging, anti-radiation and other effects. At present, proprietary Chinese medicines and health products have been developed, such as Tiepi Feng Doujing, Dendrobium Powder, Qingyanning, Yichang decoction, Dendrobium dew, Dendrobium essence, Yangyin Oral liquid and Dendrobium tablets and so on. The "Maple Dust" or "earring Dendrobium" processed by Dendrobium candidum, known as "Golden earrings" and "Golden Fengdou", sell well in Southeast Asia, Europe and the United States.

2. Promoting blood circulation and removing blood stasis to improve cardio-cerebrovascular function.

Dendrobium candidum contains esters, which can promote blood circulation and remove blood stasis, dilate blood vessels and anti-platelet coagulation, treat thrombotic occlusive pulse tube inflammation, cerebral thrombosis, arteriosclerotic occlusion and so on. Mailuoning injection, which is extracted and processed from Dendrobium and honeysuckle, has the functions of clearing heat and nourishing yin, promoting blood circulation and removing blood stasis.

3. Anti-tumor

Phenanthrene and bibenzyl extracted from Dendrobium nobile have anti-lung cancer, ovarian adenocarcinoma and promyelocytic leukemia. It can promote the growth of T cells and the production of inhibitory factors by lymphocytes, and play a role in enhancing immunity. The ethyl acetate extract of Dendrobium nobile has significant cytotoxic effects on human lung cancer cells, human ovarian adenocarcinoma cells and human promyelocytic leukemia. In particular, it has a great inhibitory effect on lung cancer cells, and the inhibition rate is as high as 74.7% 97.2%.

4. Treatment of digestive system diseases

Dendrobium nobile has an exciting effect on the intestines and can increase the amplitude of contraction. Pharmacological tests show that oral Dendrobium decoction can promote gastric juice secretion and help digestion. The effect of Dendrobium alkaloid is similar to that of non-Xetine, but its effect is weak. Dendrobium extract can stimulate the contraction of small intestinal smooth muscle and promote gastrointestinal peristalsis. Dendrobium can have a unique and satisfactory effect on chronic atrophic gastritis.

5. Treatment of ophthalmic diseases

Dendrobium has obvious therapeutic effect on ophthalmic diseases, not only has an inhibitory effect on galactose cataract, but also has a certain therapeutic effect, and the percentage of lens is 36.8%. In the treatment of cataract, it can not only inhibit the abnormal changes of enzyme activity caused by galactose, but also prevent or correct the imbalance of lens total lipid to total cholesterol caused by galactose cataract.
