1, and select hydroponic Dendrobium candidum.
Before hydroponics, plants suitable for hydroponics should be selected, preferably Dendrobium candidum seedlings that have been domesticated for more than 2 years, or some branches and buds on old plants can be cut off.
2. Treating hydroponic plants
Carefully clean the selected Dendrobium, wash off the soil on it, cut off the rotten roots, old roots or diseased roots on it, and then soak them in a solution containing carbendazim to prevent the root wounds from being infected by germs. After disinfection, put it in a cool place to dry, and then hydroponics can be carried out.
3. Prepare hydroponic containers
When choosing a hydroponic container, it is best to use a bottle with good transparency and a bottleneck on the bottle, because it can completely dissolve Dendrobium candidum in water. If you can't find such a bottle, you can fix it with tape.
4. Hydroponics
Put the prepared hydroponic plants in the bottle, and then you can start adding water into it. Some plant nutrient solution can be added to the water, usually amino acids or enzymes, and apple vinegar can also be used, but no matter which kind, don't put too much, just a small bottle cap. If you don't want to use these, you can also buy nutrient solution directly.
Extended data
The cultivation time of Dendrobium candidum is generally in spring and autumn every year, and spring is better than autumn. In Zhejiang, the best cultivation time of Dendrobium candidum is from mid-April to late June every year, during which the temperature is 65438 02 ~ 25℃, the air humidity is high, and the survival rate of transplanted test-tube seedlings is high and the growth time is long. Followed by mid-September to 10. In the meantime, it is especially necessary to do a good job in cold and antifreeze.
The cultivation of Dendrobium candidum needs to be carried out in the greenhouse. Building a greenhouse requires ventilation, shading, rainproof and insect-proof nets. According to the growth habit of Dendrobium candidum, natural factors such as light, temperature, humidity and ventilation are considered. The suitable temperature for the growth of Dendrobium candidum is 15~30℃.
Zhejiang is hot in summer, usually covered with 80% sunshade net, and the plastic film is uncovered to help cool down; It is cold in winter, and it is sealed and insulated with double-layer plastic film under the shading degree of 30%~50%. Dendrobium candidum requires that the substrate should be kept moist, and the air humidity should be kept above 80%, but water is not allowed. It is best to use sprinkler irrigation or drip irrigation when watering, and flushing irrigation is not allowed.
