1、What fertilizer is good for Dendrobium officinale?

After the germination of the new root, you can begin to spray liquid fertilizer, such as potassium dihydrogen phosphate, or potassium dihydrogen phosphate plus urea, etc., with a concentration of about 0.1%, usually sprayed once in 10 days.

2、What fertilizer is best for potted Dendrobium

Normally, after the new roots of potted Dendrobium sprout, they need to be sprayed with liquid fertilizer immediately, such as potassium dihydrogen phosphate plus urea solution, which can not only promote the growth of the stems, but also make the leaves of the plant grow very strong.

3、Cultivation method of dendrobium officinale and special nutrient

TL;DR: Wang et al. as discussed by the authors developed a technology for preparing a special fertilizer for cultivating dendrobium officinale, which can promote rooting, strengthen roots, early germinate and improve the quality.

Method for preparing dendrobium officinale nutrient fertilizer

The method comprises the following steps: determining the proportion of nutritive elements in the dendrobium officinale nutrient fertilizer by analyzing various nutritive elements absorbed in a growth process of dendrobium officinale, reacting phosphoric acid with carbamide to generate an intermediate, then introducing ammonia gas into the ...

How to fertilize Dendrobium

During the growth period, nitrogen fertilizer can be applied, and when the result is obtained, phosphorus and potassium fertilizer should be applied. Solid fertilizer should be buried far away from the root, while water-soluble fertilizer can be applied together when watering.

Noble Dendrobium Fertilizer: How and When to Use It

Apply fertilizer at the base of the plant, avoiding direct contact with leaves and stems to prevent burn. Consistency is key—stick to a regular schedule, but be ready to adjust based on your plant's response.

Application of potassium dihydrogen phosphate compound fertilizer

Potassium dihydrogen phosphate can be used as base fertilizer, top dressing and seed fertilizer, but currently it is only used for seed soaking, seed dressing and extra-root fertilization. ① Seed soaking method: soak the seeds with 0.5 kg of potassium dihydrogen phosphate and 200 to 300 kg of water for about 15 hours, remove them and dry them ...

Light and Potassium Improve the Quality of Dendrobium officinale

Conclusions: These results suggested that light and potassium affected the accumulation of active compounds in D. officinale, and the gene-flavone network analysis emphasizes the key functional genes and regulatory factors for quality improvement in the cultivation of this medicinal plant.

Compound fertilizer for dendrobium officinale and preparation method

[0003] Dendrobium officinale is rich in nutrients, has high medicinal value and economic value, and has high plantability. Dendrobium officinale is very sensitive to nutrients. At present, when people fertilize Dendrobium officinale, they generally use chemical fertilizers, urea, Feed and other raw materials are used to topdress Dendrobium ...

How to grow Dendrobium candidum at home

Dendrobium officinale cannot be fertilized when the temperature is high or the light intensity is high. It is best to adjust the fertilization time according to the changes in seasons, weather, and climate.

Dendrobium officinale, also known as "immortal grass" or "iron-peel Dendrobium," is a plant belonging to the genus Dendrobium in the Orchidaceae family. Renowned for its unique medicinal and ornamental value, it is widely used in traditional Chinese medicine, health products, and cosmetics. When applying potassium dihydrogen phosphate (KH₂PO₄) as fertilizer, the following guidelines should be observed:

1. Fertilization Timing

• Spring: Spring is a critical period for plant growth. Applying KH₂PO₄ during this time promotes new leaf development and bud formation. Fertilization is recommended in early spring when temperatures rise and plant growth accelerates.
• Autumn: Autumn marks the final stage of plant growth. Fertilizing helps the plant accumulate nutrients for winter. Apply in late autumn or early winter when temperatures drop and growth slows.

2. Fertilization Methods

• Soil Application: Dissolve KH₂PO₄ in water and evenly distribute it around the plant’s root zone. Avoid direct contact with roots to prevent burning.
• Foliar Spraying: For light-loving plants like Dendrobium, spray the foliage in the morning or evening. This enhances nutrient absorption while minimizing leaf damage.
• Drip Irrigation Fertilization: For large-scale Dendrobium farms, use drip irrigation systems to precisely control fertilizer dosage and avoid waste or overapplication.

3. Fertilization Dosage

• Dosage depends on plant growth status and soil fertility. Generally, 10–20 kg of KH₂PO₄ per mu (0.067 hectares) annually is appropriate. Excessive application may lead to rapid, unhealthy growth.
• Conduct soil tests before fertilization to analyze nutrient content. Adjust dosage based on results to ensure balanced nutrition.

4. Precautions

• Avoid over-fertilization, which can cause excessive growth, reducing quality and yield.
• Water immediately after fertilization to aid nutrient absorption.
• Monitor plants for signs of root burning. Stop fertilization if damage occurs.
• Do not mix KH₂PO₄ with alkaline substances, as this may trigger chemical reactions.

5. Evaluating Fertilization Effects

• Regularly inspect plant growth to assess fertilization outcomes. Observe growth rate, leaf color, and flower quantity.
• Adjust strategies if effects are suboptimal. Slow growth may indicate insufficient fertilization, while root burning suggests overapplication.

6. Comprehensive Management

• Combine fertilization with integrated management practices, including pest control, pruning, and water regulation. These measures collectively enhance plant health, yield, and quality.
• Pest Control: Reduce pest damage to ensure normal growth.
• Pruning: Improve air circulation and photosynthesis by shaping the plant.
• Water Management: Maintain optimal moisture levels to prevent stress from overwatering or drought.

scientific application of KH₂PO₄ requires attention to timing, methods, and dosage. Coupled with comprehensive management practices, this approach maximizes Dendrobium’s productivity and quality, benefiting agricultural production.
