Applying climate-smart agriculture practices, such as foliar spraying with growth stimulants and improving drought tolerance, seems to be a rational solution in drought-prone areas. The present study aimed to evaluate irrigation regimes.

5、Research Progress on Role and Mechanisms of Foliar Fertilizer in

Through extensive research on a large number of domestic and foreign literatures, it reviews the development of foliar fertilizers, summarizes the types and characteristics of different foliar fertilizers, and concludes the roles of different types of foliar fertilizers in promoting plant growth and alleviating plant stress.

Foliar nutrition: Potential and challenges under multifaceted

Foliar fertilization has been well recognized for two decades to affect crop productivity, however, the consequences of foliar spray under multiple environmental stresses remains elusive, albeit evidence to resilience agriculture has grown widely.

Effective Application Tips For Using Ammonium Phosphate Fertilizer In

Application Methods: Techniques for broadcasting, banding, or foliar spraying ammonium phosphate effectively Ammonium phosphate fertilizer, a potent source of nitrogen and phosphorus, demands precise application to maximize its benefits.

Combining Seed Dressing and Foliar Applications of Phosphorus

We conclude that a combination of seed dressing and foliar applications of P is potentially a better alternative to conventional soil-based application, offering greater efficiency in use of applied P both in terms of P-uptake rate and grain yield.

What Foliar Fertilizers Can Promote Early Maturity of Rapeseed Seeds?

Currently, numerous foliar fertilizer products are available on the market, such as potassium dihydrogen phosphate, urea, ammonium sulfate, and borax. While these fertilizers generally promote plant growth, their effectiveness varies depending on the crop and growth stage.

Optimal phosphorus management strategies to enhance crop productivity

In summary, optimal P managements in the rapeseed season could stabilize the crop yield, promote P use efficiency and the capacity of soil P supply in the rapeseed-rice rotation, especially in low P fertility soil.

Foliar spraying of phosphate fertilizer is a critical practice to enhance rapeseed yield and quality. Phosphorus, an essential nutrient for plant growth, plays a vital role in the development, flowering, and fruiting stages of rapeseed. Through foliar application, phosphorus deficiencies can be effectively addressed, promoting robust growth. Below are detailed methods for applying phosphate fertilizer via foliar spraying:

1. Preparing Materials

• Select qualified phosphate fertilizers such as diammonium phosphate (DAP) or monoammonium phosphate.
• Prepare spraying equipment, including manual or electric sprayers.
• Ensure adequate water supply for dilution.
• Use personal protective gear (e.g., masks, gloves) to avoid exposure to chemicals.

2. Diluting the Phosphate Solution

• Mix phosphate fertilizer with water at a ratio of 100 grams of fertilizer to 5,000 milliliters of water.
• Spray uniformly over rapeseed leaves using a sprayer, avoiding direct contact with stems or roots.
• Hold the sprayer nozzle at a 30°–45° angle to ensure even coverage on leaf surfaces.

3. Key Considerations

• Clean equipment thoroughly before use to prevent contamination.
• Avoid windy conditions during spraying to maintain effectiveness.
• Remove fallen leaves or weeds after application to prevent nutrient absorption issues.

4. Optimal Timing

• Apply during rapeseed’s vigorous growth stage, when phosphorus demand is highest.
• Early morning or late evening are ideal times, as cooler temperatures improve nutrient absorption.

5. Application Frequency

• 1–2 sprays per mu (0.067 hectare) are typical, depending on growth conditions and soil fertility.
• Increase frequency if soil fertility is low during later growth stages.

6. Spraying Technique

• Flush the sprayer with water before use to clear blockages.
• Adjust spray angle and distance for uniform coverage.
• Avoid missing or overlapping areas. After application, clean residual solution from the sprayer.

7. Safety and Troubleshooting

• Monitor leaf reactions closely; halt spraying immediately if abnormalities occur.

• Stop application and take remedial measures if phytotoxicity symptoms (e.g., leaf burn) appear.

• Wear protective gear to avoid chemical exposure.

• Foliar phosphate spraying is a highly effective method to boost rapeseed productivity and quality. Proper fertilizer selection, dilution ratios, timing, and techniques maximize growth benefits.

• Prioritize standardized operations and safety protocols to ensure both efficacy and plant health.

• This method not only meets phosphorus demands but also contributes to improved soil structure and long-term fertility.

Note: Adjust practices based on local climate, soil conditions, and crop specifics.
