1、The effect of root promoting fertilizer on seedlings growth of

In the production and cultivation of B. chinense, it was extremely important to apply fertilizer reasonably to inhibit the growth of aboveground organs, promote root growth, and facilitate biosynthesis and accumulation of saikosaponins.

2、[Effects of humic acid water

In conclusion, the application of humic acid water-soluble fertilizer diluted 1 800 times can significantly promote the growth of B. chinense seedlings, enhance root vitality, improve seedling stress resistance, and enhance photosynthesis.

3、Effects of <i>Trichoderma harzianum</i> biofertilizer on growth, yield

Our study showed that T. harzianum bio-fertilizer could improve the growth parameters, quality, and yield of radix bupleuri, mainly due to improvement of soil fertility and abun-dance of beneficial bacteria (Wang et al., 2017).

Metabolomics Analysis Reveals Potential Mechanisms in Bupleurum L

Although there was no obvious discrepancy between HN and LN observed in root length, the total length was significantly higher at HN supply (Figure 1 D), indicating that a high level of nitrogen fertilizer plays a greater role in promoting the growth of the aerial parts than roots in Bupleurum.

Seed treatment and cultivation techniques of Bupleurum

Applying potassium fertilizer alone can be foliar sprayed with organic potassium fertilizer produced by Shaanxi Yangling Juchuan Fuwan potassium Co., Ltd., each time 3kg/ is applied.

A foliar spray application of indole

Foliar applied indole-3-butyric acid (IBA) was better or equally as effective as a basal dip. A foliar application of 150 to 300 mg·L–1 IBA at 0.8 L·m –2 is effective at promoting root growth.

Bupleurum Fertilizer: How and When to Use It

Understanding N-P-K ratios is crucial for optimal plant growth. The ideal ratios for Bupleurum are typically 10-10-10 or 5-10-5, providing a balanced nutrient profile that supports healthy development. Nitrogen plays a vital role in promoting leafy growth and overall plant health.

Metabolite Profiles Provide Insights into Underlying Mechanism in

By comparing the indexes and metabolomics analysis results of Bupleurum under three phosphorus fertilizer levels, it can be concluded that phosphorus plays a pivotal role in the growth of Bupleurum.

Effects of urea or potassium sulfate compound fertilizer on

Abstract: The aim of this study was to understand the effects of fertilizers on the yield, contents of medicinal components and rhizosphere soil of Bupleurum chinense DC. in Shiyan City, Hubei Province.

Metabolomics Analysis Reveals Potential Mechanisms in Bupleurum L

Although there was no obvious discrepancy between HN and LN observed in root length, the total length was significantly higher at HN supply (Figure 1D), indicating that a high level of nitrogen fertilizer plays a greater role in promoting the growth of the aerial parts than roots in Bupleurum.

Bupleurum (Bupleurum chinense DC) is a common traditional Chinese herb known for its effects in clearing heat, relieving exterior disorders, soothing the liver, alleviating depression, and lifting yang to relieve prolapse. In agricultural production, Bupleurum is also used to enhance crop quality and yield, particularly in promoting root system development.

1. The Relationship Between Growth Characteristics and Root Development of Bupleurum

As a perennial herbaceous plant, Bupleurum has a well-developed root system primarily distributed within 20–30 centimeters below ground. This root structure aids the plant in absorbing soil moisture and nutrients while stabilizing the soil and preventing erosion.

2. The Importance of Foliar Fertilization

Foliar fertilization involves applying nutrients directly to plant leaves and stems via spraying. This method improves fertilizer utilization, reduces nutrient loss, and rapidly replenishes essential elements to promote growth.

3. Optimal Timing for Foliar Fertilization

For Bupleurum, timing is critical. Spring is the key growth period, during which foliar fertilization effectively supports development. Summer and autumn applications are also possible but should avoid high-temperature periods to prevent reduced efficacy.

4. Methods for Foliar Fertilization

4.1 Preparing Materials

• Fertilizer: Select balanced compound fertilizers (e.g., nitrogen, phosphorus, potassium) or microelement fertilizers suitable for Bupleurum.
• Water: Use clean water for spraying.
• Tools: Employ sprayers or manual tools, adjusting nozzle size to control coverage.

4.2 Spraying Techniques

• Even Coverage: Ensure uniform distribution across all leaf surfaces to avoid overconcentration or dilution.
• Moderate Application: Adjust dosage based on plant size and nutritional needs. Excessive use may harm growth, while insufficient amounts may hinder development.
• Avoid Heat: Steer clear of peak temperatures to maintain fertilizer effectiveness.

4.3 Precautions

• Safety First: Wear masks, gloves, and protective gear to prevent ingestion or skin contact.
• Monitor Response: Observe plant reactions post-application and address abnormalities promptly.
• Combine Treatments: Coordinate foliar fertilizers with other fertilizers or pesticides for optimal results.

5. Evaluating the Effects of Foliar Fertilization

After consistent application, assess outcomes through:

• Growth Rate: Accelerated growth and darker green foliage.
• Leaf Health: Thicker leaves, distinct veins, and reduced yellowing or wilting.
• Root Development: Measure improvements in root length, density, and overall health.

As a vital raw material in traditional Chinese medicine, enhancing the quality and yield of Bupleurum is critical to the中医药 industry. Scientific foliar fertilization not only boosts growth but also improves medicinal standards, meeting market demands. Promoting rational use of foliar fertilizers holds significant practical value for advancing both productivity and quality in Bupleurum cultivation.
