Abstract Foliar fertilization, an effective method to regulate plant nutrition has attracted much attention.

Soil Fertilization Techniques for Chinese Yam

In the cultivation and management of yam, we should focus on the application of base fertilizer, the looseness of soil, the treatment of yam species, timely topdressing, disease prevention and control, and take measures to promote the growth of rhizome as far as possible.

Chinese yam yield is affected by soil nutrient levels and

Objective:The current fertilization methods for Chinese yam are uneconomic and unfriend to environ-ment.A rational one is very important to achieve desired balance of high yield of Chinese yam,economic and friend to environment.Here,we studied the effects of nitrogen (N),phosphorus (P),and potassium (K)fertilizers on the yield of 'Qinfeng ...

Fertilization on Chinese Yam: Effects of N and K Rates and Combined

A field experiment was conducted to study the appropriate rates of N and K and the effects of combined application of Mg and B on Chinese Yam, to provide a basis for high yield and good quality production and rational fertilization.

Plant Performance and Soil Fungal Community Impacts of Enhancing

Spraying foliar fertilizer can directly affect Chinese yam's growth and chemical content, regulate soil environments. The effects depend on nutrient element combinations.

Foliar application of bioorganic fertilizer enhances plant nutrients

The enzyme activity has greatly increased with bioorganic fertilization, demonstrating that foliar application directly influence the soil enzymes in the rhizosphere.

Chinese yam, scientifically known as Dioscorea opposita and also called "Huai Shan" or "Huaishan," is a common traditional Chinese medicinal herb with significant pharmacological value. In agricultural production, foliar fertilization is an effective method to enhance its yield and quality. Below is a detailed explanation of the effects, application methods, and precautions for using foliar fertilizers on Chinese yam.

I. Effects of Foliar Fertilization on Chinese Yam

1. Promotes Growth Foliar fertilizers provide essential nutrients such as nitrogen (N), phosphorus (P), and potassium (K), which accelerate plant growth. For Chinese yam, foliar spraying increases growth rate and yield.

2. Enhances Stress Resistance Foliar fertilizers contain plant hormones like gibberellin and cytokinins, which regulate physiological activities and improve resistance to pests, diseases, and adverse conditions. After spraying, the plant’s disease/pest resistance improves, reducing pesticide use and lowering production costs.

3. Improves Quality Nutrients in foliar fertilizers promote the synthesis of active compounds in Chinese yam, such as saponins, thereby enhancing its medicinal efficacy.

4. Conserves Resources Foliar fertilization avoids soil application, reducing nutrient loss, environmental pollution, and resource waste.

II. Application Methods for Foliar Fertilization

1. Select the Right Fertilizer Choose a foliar fertilizer based on the growth stage and nutritional needs of Chinese yam. Options include water-soluble or oil-based formulations. Water-soluble fertilizers can be directly sprayed, while oil-based ones require dilution with water.

2. Dilute the Fertilizer Follow instructions to dilute the fertilizer. A typical dosage is 50–80 ml per mu (0.5–0.8 liters per hectare) when using a sprayer.

3. Optimal Spraying Time Apply during the growing season (spring to autumn) in the morning or evening when temperatures are cooler, aiding absorption.

4. Spraying Technique Use a sprayer to evenly coat the leaves, avoiding stems and roots. Maintain proper distance to prevent over-concentration and potential damage.

III. Precautions for Foliar Fertilization

1. Concentration Control

   • Water-soluble: 0.2–0.5% solution.
   • Oil-based: 0.3–0.5% solution. Excessive concentrations may cause toxicity.

2. Weather Conditions Apply on calm, sunny days. Avoid rain, high temperatures, drought, or heavy rain to ensure effectiveness.

3. Crop Compatibility Use fertilizers specifically designed for Chinese yam. Monitor plant health and adjust applications if abnormalities arise.

4. Safety Measures Wear protective gear (mask, gloves) to avoid skin/eye contact. Keep away from open flames and power sources.

Foliar fertilization is a highly effective method to boost Chinese yam’s growth, stress resistance, and quality. By optimizing application techniques and precautions, farmers can achieve higher yields and improved medicinal value. adjustments based on specific conditions are critical for optimal results.
