1、我国微量元素肥料研究及应用的历程与展望

Up to now, the micronutrient fertilizer products in China have gone through the development from merely traditional inorganic salts to various types including chelating, slow/control-release, and nanoparticle micronutrient fertilizers.

2、Microelement

Microelements refer to rare or absent elements in reservoir water that can be used as tracers, characterized by their stability, low cost, high measurement precision, and stability at high temperatures, although they require special equipment for detection.

Complex water

Microelement fertilizers (boron, molybdenum, copper, zinc, etc.) play an important role in modern crop production technologies to increase yields and product quality, along with macro fertilizers (nitrogen, phosphorus, potassium).

Types of Citrus Microelement Water

Citrus microelement water-soluble fertilizers are a category of water-soluble fertilizers specifically designed to provide essential microelements for citrus trees.

水溶性肥料营养流失问题及新型增效剂研发前景探讨

A water-soluble fer-tilizer is a new type of chemical fertilizer that combines water with fertilizer in an innovative me-thod. In modern agriculture, green food has grown into a unique commodity with high low-carbon, green, and economic value.

What Are The Types Of Water

As a type of quick acting fertilizer, water-soluble fertilizer has a comprehensive range of nutrients, and there are different formulas for fertilizers according to the fertilizer requirements of different crops.

The functions and types of water

According to the differences in their elements, macronutrient water-soluble fertilizers can be classified into high-efficiency type, high-nitrogen type, high-phosphorus type, high-potassium type and organic compound fertilizers, etc.

What is microelement fertilizer

According to the types of micro fertilizer compounds, they can be roughly divided into five categories: (1) Soluble inorganic salt. Most of these fertilizers are sulfate. (2) Insoluble inorganic salt. Most of them are phosphates and carbonates, and some of them are oxides and sulfides.

Section 4: Microelements

Water-soluble fertilizer packages (i.e. S.T.E.M., M.O.S.T. or Compound 111) may also be added to the substrate before, during or after planting. The micronutrients in these fertilizers are either water-soluble salts or chelated minerals that are readily available to the crop.

Water-soluble fertilizers, also known as liquid fertilizers, are nutrient solutions applied to plants through irrigation systems. These fertilizers typically contain high concentrations of essential nutrients, including nitrogen (N), phosphorus (P), potassium (K), and microelements, to provide plants with full or partial nutritional needs for growth.

The microelements in water-soluble fertilizers mainly include:

1. Iron (Fe): Iron is an essential microelement for plant growth, critical for photosynthesis and respiration. Iron deficiency can disrupt chlorophyll synthesis, stunting normal plant development.

2. Zinc (Zn): Zinc is vital for plant growth, influencing development, photosynthesis, and disease resistance. Zinc deficiency leads to slow growth, yellowing leaves, and even plant death.

3. Copper (Cu): Copper is necessary for chlorophyll synthesis and root development. Its deficiency impairs photosynthesis and results in poor plant health.

4. Manganese (Mn): Manganese supports root nodule formation, chlorophyll production, and energy metabolism. Manganese deficiency hinders plant growth and development.

5. Boron (B): Boron strengthens stems, promotes fruit expansion, and enhances stress resistance. Boron deficiency causes slow growth, small fruits, and vulnerability to pests and diseases.

6. Molybdenum (Mo): Molybdenum is key for photosynthesis, nitrogen metabolism, and disease resistance. Its deficiency reduces crop yields and growth.

7. Chlorine (Cl): Chlorine regulates osmosis, ion balance, and disease resistance. Chlorine deficiency impacts plant development.

8. Selenium (Se): Selenium boosts antioxidant defenses, photosynthesis, and disease resistance. Selenium deficiency lowers crop yields and growth.

9. Silicon (Si): Silicon aids cell wall formation, seed germination, and stress resistance. Silicon deficiency weakens plant growth and disease resistance.

10. Nickel (Ni): Nickel supports photosynthesis, nitrogen metabolism, and disease resistance. Nickel deficiency reduces crop yields and growth.

In agricultural production, rational use of water-soluble fertilizers can improve crop yields and quality, reduce chemical pesticide usage, and protect the environment. excessive application may cause soil or groundwater pollution. Thus, it is crucial to follow moderation principles, tailoring formulations and applications to soil and crop requirements.
