Planting Method of Dendrobium Officinale in Pot
Dendrobium officinale, as a rare medicinal plant, has become a new favorite for home potted plants due to its ornamental value and health benefits. Mastering scientific planting methods can not only improve the survival rate but also decorate the living space with the unique beauty of orchid plants. This article provides a detailed explanation of the technical essentials from pot selection to maintenance, helping you easily create a home Dendrobium garden.
I. Basic Preparation for Planting Dendrobium Officinale
1.1 Criteria for Container Selection
It is recommended to use unglazed ceramic or purple sand pots with a diameter of 10-15cm, and the pot must have 3 or more drainage holes. Special designs such as snake wood pots or hollow plastic pots can enhance breathability, avoiding closed containers like glazed porcelain pots.
1.2 Scientific Substrate Mixture
Use the layered filling method: the bottom layer is铺ed with 2cm volcanic stone particles, the middle layer is mixed with pine bark (particle size 1-2cm) and broken bricks (1:1), and the top layer is covered with fermented pine needles and coconut bran (3:1). Renew 5cm of new substrate every year to maintain nutrients.
II. Planting Techniques for Dendrobium Officinale
2.1 Disinfection Process
The substrate needs to be steamed at high temperature for 30 minutes, then soaked in a carbendazim solution (1:1000) for 2 hours after cooling. The plant roots should be treated with rooting powder (0.1% concentration) to increase the root germination rate by 30%.
2.2 Standard Planting Procedures
Place the treated Dendrobium seedlings in the pot, keeping the pseudobulbs exposed above the substrate surface. Use a layered filling method: first fill with large particle substrate to fix the roots, then fill the gaps with fine particles, and finally gently tap the pot walls to let the substrate settle naturally.
III. Maintenance Management of Dendrobium Officinale
3.1 Key Points of Environmental Control
Maintain 60%-80% air humidity, shade 70% or more in summer, and receive full sunlight in winter. Keep the temperature within the range of 18-28℃, and move the plant indoors if it is below 5℃. Rotate the pot 180 degrees every 3 days to ensure even light exposure.
3.2 Water and Fertilizer Management Plan
Use the immersion pot method for watering, twice a week (summer) / once a week (winter). Apply orchid special fertilizer (N-P-K=20-20-20) every 15 days during the growing period, and switch to potassium dihydrogen phosphate foliar fertilizer (0.2% concentration) during the budding period.
3.3 Disease and Pest Control
Focus on controlling red spiders (apply abamectin) and (T-J) disease (alternatively use mancozeb and tebuconazole). Spray the back of the leaves with garlic extract (1:50) monthly to effectively prevent diseases.
Through the management of three key stages: scientific pot selection, precise planting, and detailed maintenance, Dendrobium officinale potted plants can produce 3-5 new shoots per year. It is recommended to propagate by division every spring, replace the substrate every 3 years, and配合合理采收策略, to continuously obtain Dendrobium plants with both ornamental and medicinal value.
