1、The Key Ingredients of Foliar Fertilizer and Their

When included in foliar fertilizers, they can be readily absorbed by plants and used for protein synthesis. Amino acids can also enhance the plant's resistance to stress, improve nutrient uptake, and promote root development.

2、Foliar Feeding

Foliar feeding is nothing but spraying liquid fertilizer directly to the leaves as opposed to in the soil (Puglisi et al., 2022). Their epidermis and stomata work cleverly to absorb the nutrients (potassium, phosphorous, and nitrogen) from liquid fertilizer for the growth of plants.

3、Foliar Fertilizer Technology Developed for Agriculture

叶面营养有三种营养来源：无机盐、有机复合体和合成螯合物。 每一种不同的营养源都有不同的特性，如溶解度、分子大小、电荷和潮解点。 正是这些特性的结合影响了养分的吸收、输送，并最终影响了叶面营养的效率。 溶解性与吸收性. 想要使叶面吸收营养物质，就必须将其溶解，而非悬浮在液体中。 将可溶性硫酸锌与纳米级低溶解度的氧化锌进行比较的研究表明，即使氧化锌的颗粒直径为纳米级（小于100纳米），其吸收水平仍低于溶解度较高的来源。 分子大小影响吸收效果. 营养分子的颗粒大小会影响植物表面或角质层吸收的速度。 角质层的孔隙可以吸收2.4 nm以下的颗粒，而43 nm以下的颗粒则能通过气孔吸收。 对肥料颗粒大小的研究发现，许多肥料颗粒的直径 …

What are the Ingredients in Vegetable Special Effects Foliar Fertilizers?

Foliar fertilizer application after soil fertilization is an effective method to increase the contents of trace elements in crops and crop yield, and to improve the soil environment.

Types of foliar fertilizers

There are many types of foliar fertilizers. According to their effects and functions, foliar fertilizers can be summarized into four categories: nutritional, regulatory, biological and compound.

Foliar Fertilizer

Definition: Foliar fertilizer refers to a liquid fertilizer solution applied directly to plant foliage, where nutrients are absorbed through the leaves and stems.

Understanding Foliar Fertilizers: A Guide for Farmers

Macronutrient Foliar Fertilizers – These contain essential nutrients like nitrogen (N), phosphorus (P), and potassium (K), which are required in large amounts for plant growth.

Foliar Fertilizer Application Technology: Precision Application Guide

Main Component Classification of Foliar Fertilizers. Taking nitrogen (N), phosphorus (P), and potassium (K) as the main components, they are used to quickly supplement the basic nutrients required for crop growth.

Foliar fertilizers: Enhancing nutrient uptake for healthy plants

Unlike conventional soil-applied fertilizers, which are absorbed through the roots, foliar fertilizers are absorbed through the stomata (tiny pores) on the leaf surface or directly through the leaf cuticle.

Research Progress on Role and Mechanisms of Foliar Fertilizer in

Foliar fertilization can enhance the antioxidant activity of crops, regulate photosynthetic activity, energy metabolism and nutrient assimilation and other physiological processes to promote crop growth.

Fengchengling foliar fertilizer is a common plant nutrient supplement used to promote plant growth and increase yield. It typically contains a variety of nutritional components to meet the needs of plants at different growth stages. Below is a detailed explanation of the ingredients in Fengchengling foliar fertilizer:

1. Nitrogen Fertilizer: Nitrogen is one of the essential macroelements for plant growth. Nitrogen fertilizer enhances photosynthetic efficiency, promotes leaf development, and strengthens disease resistance. In Fengchengling, nitrogen is often provided in the form of urea or ammonia solution.

2. Phosphorus Fertilizer: Phosphorus is a critical micronutrient for plants. Phosphorus fertilizer stimulates root growth, improves stress resistance, and boosts defense against pests and diseases. In this fertilizer, phosphorus commonly appears as superphosphate or potassium dihydrogen phosphate.

3. Potassium Fertilizer: Potassium is another essential micronutrient. Potassium fertilizer regulates water balance, enhances cold and drought tolerance, and facilitates nutrient uptake. Sources include potassium sulfate or potassium chloride.

4. Trace Element Fertilizers: Besides nitrogen, phosphorus, and potassium, plants require trace elements like iron, zinc, manganese, copper, boron, and molybdenum. These are often chelated in Fengchengling to improve absorption efficiency.

5. Organic Matter: Organic substances provide rich nutrients and energy for plants. Components like humic acid and bio-organic fertilizers are commonly included.

6. Enzyme Preparations: Enzymes aid in breaking down soil nutrients for better plant absorption. Fengchengling may contain compound enzymes to enhance effectiveness.

7. Hormones: Hormones regulate plant growth and development, improving stress adaptability. Natural extracts such as gibberellin and indoleacetic acid are typical ingredients.

8. Microbial Fertilizers: Microorganisms improve soil structure, enrich fertility, and strengthen disease resistance. Strains like Bacillus subtilis and Bacillus amyloliquefaciens are often used.

9. Water-Soluble Fertilizers: These dissolve quickly in water for rapid plant absorption. Examples include calcium nitrate and potassium nitrate.

10. Slow-Release Fertilizers: Slow-release formulas provide nutrients over extended periods, matching plants’ varying needs. Controlled-release compound fertilizers are typical components.

Fengchengling foliar fertilizer comprises nitrogen, phosphorus, potassium, trace elements, organic matter, enzymes, hormones, microbial agents, water-soluble nutrients, and slow-release compounds. These ingredients work synergistically to support healthy plant growth and high yields. When using Fengchengling, it is recommended to select products based on specific plant needs and growth stages, following dosage and application guidelines.
