1、Effects of foliar fertilizer on rice growth and yield

Among them, the microbial foliar fertilizer Miaodundun, the regulatory foliar fertilizer Abscisic acid + Indolebutyric acid, and the compound foliar fertilizer Zhenfengrui combination demonstrated better yield increasing and income enhancing effects.

2、Usage and Dosage Guidelines for Rice

This article aims to shed light on the importance of appropriate fertilizer dosing in rice production, exploring the different types of fertilizers commonly used and their contribution to successful cultivation.

3、Growth Stage

The present study demonstrated that foliar application of Fe improved plant growth, Fe use efficiency, Fe remobilisation, and grain Fe biofortification in rice plants; nevertheless, variations were apparent among different Fe compounds, application stage, and number of sprays.

4、Effects of fertilizer types and dosage on rice growth and yield

The results showed that the grain filling rate of rice reached a high level under the combination of organic-inorganic fertilizers and silicon calcium fertilizers, and a longer grain filling time was beneficial for grain formation.

Application Progress and Prospect of Rice Foliar Fertilizer

In recent years, China has encouraged the use of foliar fertiliser on rice in a big way, and there are a lot of products, but the quality is inconsistent, and the spraying method still needs to be improved.

Here, pot experiments in rice were conducted to characterize the effects of four types of foliar-applied Fe fertilizer (chelated ferrous Fe, ferric Fe, ionic ferrous Fe, and ferric Fe) at three doses (20, 50, and 100 mg L-1) on photosynthetic capacity, antioxidant ability, yield, and Cd accumulation in Cd-contaminated soil.

Foliar feeding of these fertilizers not only replenishes plant nutrients but also act as catalyst in the uptake and use of certain macronutrients. Research showed that all foliar applied nutrients are absorbed by the leaves.

Iron (Fe) fertilizer can reduce cadmium (Cd) uptake and toxicity in rice, but the underlying mechanisms of Cd mitigation by different fertilizers are poorly understood.

Foliar fertilization is a highly efficient supplementary method for rice cultivation in Hebei. It involves spraying nutrients directly onto rice leaves during critical growth stages to improve quality and yield. Below is a detailed guide on the application and dosage of foliar fertilizer for rice in this region.

I. Selection and Preparation of Foliar Fertilizer

1. Choosing the Right Fertilizer: Select foliar fertilizers based on the rice growth stage and soil conditions. Common types include nitrogen (N), phosphate (P), potassium (K), and micronutrient fertilizers. For example:

   • Use high-nitrogen fertilizer for nitrogen-deficient fields.
   • Apply phosphate or potassium fertilizers for soils lacking these elements.

2. Preparation: Dissolve the fertilizer in water as per the manufacturer’s instructions. For solid fertilizers, grind them into powder before mixing. Ensure complete dissolution before use.

II. Application Methods

1. Timing: Apply foliar fertilizer during critical growth stages: tillering stage, booting stage, and heading stage. These periods demand high nutrient intake, and foliar spraying ensures rapid absorption.

2. Spraying Technique:

   • Direction: Spray from the upper to lower parts of the plant to avoid leaf burn. Avoid direct contact with the main stem or branches.
   • Concentration: Dilute the fertilizer to the recommended strength. Overly concentrated solutions may damage rice plants. Adjust concentrations based on field results.
   • Frequency: Apply 2–3 times per mu (0.067 hectares), with 7–10 days between applications. Avoid excessive use to prevent waste.

III. Dosage Control

1. Proportionality: Follow the specified ratios on fertilizer labels. Consult agricultural experts or technical guides if uncertain.

2. Optimal Application:

   • Consider soil fertility and crop requirements.
   • Overapplication may lead to nutrient excess, while insufficient doses might fail to meet demands. Balance precision for best results.

IV. Key Considerations and Recommendations

1. Safety Precautions:

   • Wear protective gear to avoid skin or eye contact with chemicals.
   • Ensure ventilation and environmental hygiene to prevent contamination or poisoning.

2. Integrated Fertilization: Foliar fertilization complements but does not replace base fertilization (e.g., soil fertilizers). Combine methods based on soil tests and crop needs.

3. Monitor Plant Response: Observe rice health post-application. Address issues like leaf yellowing or wilting promptly by adjusting strategies.

Mastering foliar fertilizer usage for rice in Hebei requires flexibility and scientific rigor. When applied correctly, this method enhances growth quality, boosts yields, and maximizes agricultural economic benefits.
