1、Application of carbon

Through this study, we identified the positive effects of carbon-based nutrient fertilizers on seed yield and soil fertility in tree peony, aiming to provide a sustainable and efficient fertilizer option for agricultural production.

2、Key points for scientific fertilization of Paeonia rockii

Application of boron fertilizer (0.1% borax solution for root irrigation) at 30 days before anthesis combined with removal of lateral buds reduced nutrient competition.

3、Appropriate application rate and ratio of N, P, and K fertilizers for

Abstract Objective Peony (Paeonia suffruticosa Andr.) is a renowned woody ornamental plant in China, we investigated the effects of nitrogen (N), phosphorus (P), and potassium (K) application rates and ratios before and after flowering on the growth and ornamental quality of potted peony.

4、Major Fatty Acid Compositions and Antioxidant Activity of Cultivated

Paeonia ostii is now being extensively planted for oil extraction in China, which is recognized as a single oil-use tree peony cultivar and commonly called 'Fengdan'. This study investigated the effects of nitrogen fertilizer on oil yield, fatty acid compositions and antioxidant activity of P. ostii …

Application of carbon

This study illustrated that the concurrent application of carbon- based nutrient fertilizers with chemical fertilizers substantially augmented both seed yield and oil content in tree peony.

Peony Fertilizer 101: The Ultimate Guide to Fertilizing Peonies for

We’ll discuss the types of fertilizers that work best for peonies, the timing and methods of application, and how to troubleshoot common fertilization problems. By following these guidelines, even beginners can ensure their peonies receive the optimal care they need to flourish.

What Type of Fertilizer for Peonies? Blooming Secrets Revealed

This comprehensive guide delves into the world of peony fertilizers, exploring the different types, their benefits, and how to apply them effectively to ensure your peonies thrive.

Compound Fertilizer Application Improves the Growth of Herbaceous Peony

In this study, compound fertilizer application significantly improved photosynthetic performance in heat-stressed herbaceous peony, with Pn in T1/T2 treatments 5–10 times higher than controls.

Compound Fertilizer Application Improves the Growth of Herbaceous Peony

Results demonstrated that compound fertilizer supplementation significantly improved plant growth under elevated temperatures, manifesting enhanced phenotypic characteristics, elevated antioxidant enzyme activities, and increased nutrient accumulation.

What type of soil and fertilization do peonies require?

Peonies aren’t heavy feeders, but they benefit from specific types of fertilizers that promote balanced growth. Over-fertilizing, especially with nitrogen-heavy fertilizers, can lead to excessive foliage at the expense of flowers.

In the Gansu region, peonies are cultivated under unique geographical and climatic conditions, leading to distinct fertilizer requirements compared to general flowering plants. Peony-specific fertilizers typically contain high proportions of nitrogen (N), phosphorus (P), potassium (K), and trace elements, which are essential for healthy peony growth. Below are several spraying methods for peony-specific fertilizers suitable for the Gansu region:

I. Preparation Phase

1. Soil Testing

• Purpose: Determine whether soil nutrients adequately support peony growth.
• Method: Collect soil samples from different depths for laboratory analysis to assess pH, organic matter content, nutrient levels, and other indicators.

2. Pre-Fertilization Soil Treatment

• Purpose: Improve soil structure and fertility.
• Method: Apply organic fertilizers (e.g., compost or green manure) to enhance microbial activity, supplemented with chemical fertilizers as base nutrients.

3. Fertilizer Selection

• Purpose: Choose the appropriate peony-specific fertilizer based on soil test results.
• Method: Select a balanced formula containing N, P, K, and trace elements, while adjusting for soil pH.

II. Fertilization Methods

1. Trench Application

• Advantages: Suitable for large-scale fields; easy management.
• Steps: Evenly spread fertilizer in trenches between rows or plants, then cover with soil to ensure direct contact with roots.

2. Ditch Application

• Advantages: Allows precise control of fertilizer amounts; ideal for small areas or specific locations.
• Steps: Dig a small pit, place fertilizer directly into it, and cover with soil.

3. Foliar Spraying

• Advantages: Rapidly replenishes nutrients; suitable during peak growth periods.
• Steps: Use a specialized foliar sprayer to apply diluted fertilizer solution to peony leaves, avoiding excessive moisture on foliage.

4. Root-Targeted Topdressing

• Advantages: Directly targets roots for efficient absorption.
• Steps: Dissolve fertilizer in water and apply near peony roots via an irrigation system.

III. Key Considerations

1. Timing: Apply fertilizer according to peony growth cycles. Spring is critical for peony development, requiring increased frequency.
2. Dosage: Base amounts on soil test results and product guidelines; over- or under-fertilization may harm plants.
3. Method: Choose the most suitable approach based on soil conditions and plant needs.
4. Environmental Protection: Avoid overapplication to prevent pollution; prioritize eco-friendly fertilizers.

The application methods for peony-specific fertilizers in Gansu vary, each with its own strengths and limitations. In practice, flexibility is key: tailor methods to soil conditions, plant health, and fertilization goals to ensure robust growth. Rational fertilization not only enhances peony quality and aesthetic value but also reduces environmental impact, promoting sustainable agricultural development.
