Макроэлементное водорастворимое удобрение NPK

 Macronutrients refer to the essential nutrient elements that are required or contained in a large amount for the normal growth and development of plants. Generally refers to the six elements of carbon, hydrogen, oxygen, nitrogen, phosphorus and potassium. Carbon, hydrogen, and oxygen mainly come from air and water, which are the main components of plant organisms, and nitrogen, phosphorus and potassium are detailed below:

1. Nitrogen is the main component of protein, nucleic acid, and phospholipid. They are an important part of protoplasm, cell nucleus and biological membrane. Therefore, nitrogen is called the element of life.
Nitrogen is the constituent element of enzymes and many coenzymes and prosthetic groups.
Nitrogen is also a component of certain plant hormones (such as auxin and cytokinin) and vitamins (B1, B2, B6, etc.), and they have a regulatory effect on life activities.
Nitrogen is a component of chlorophyll and is closely related to photosynthesis.
When nitrogen is deficient, the synthesis of protein, nucleic acid, phospholipid, etc. is hindered, the plant growth is short, there are few branches, and the leaves are small and thin.
Chlorophyll synthesis is affected, branches and leaves turn yellow, even withered, and gradually upward from the lower leaves, resulting in a decrease in yield.

2. Phosphorus is the main component of nucleic acid, nuclear protein and phospholipid, and is closely related to protein synthesis, cell division and cell growth;
Participate in photosynthesis and respiration process, a lot of phosphorus is a component of ATP;
Phosphorus participates in the metabolism and transportation of carbohydrates;
Phosphorus also plays an important role in nitrogen metabolism. Phosphorus is a component of its coenzyme in the process of nitric acid reduction;
Phosphorus is related to fat metabolism and is a component of enzymes or energy substances in metabolism.
When phosphorus is deficient, the old leaves are first affected, especially at low temperature, the phosphorus deficient plants often turn purple or red, and the stems are purple-red and lose their luster.
The first symptom of phosphorus deficiency is that the entire plant is short and the shape of the leaves may be distorted.
In severe phosphorus deficiency, necrotic areas may appear on the manifestation site.
3. Potassium is the activator of more than 60 enzymes in cells, and it plays an important role in carbohydrate metabolism, respiration and protein metabolism.
Potassium ions promote protein synthesis. When potassium ions are sufficient, more proteins are formed and soluble nitrogen decreases.
Potassium ions are related to the synthesis of sugars. Potassium ions also promote the transport of sugars to storage organs.
Potassium ions are an important component of cell osmotic potential. In the root, K+ is transported from the parenchyma cells to the duct, reducing the water potential in the duct, so that water can be transported from the root surface to the xylem.
When potassium is lacking, the stems are weak and easy to fall.
Cell osmotic potential is reduced when potassium is lacking. In addition, potassium has the effect of swelling the protoplast colloid. When potassium is lacking, the drought resistance and cold resistance of plants are reduced.
The leaf loses water, protein and chlorophyll are destroyed, the color of the leaf turns yellow, and gradually becomes necrotic; the leaf edge is scorched and grows slowly, while the middle part of the leaf grows faster, and the whole leaf forms a cup-shaped bend or shrinks.
The element deficiency symptoms first appeared in the lower old leaves.

1. Balanced water-soluble fertilizer
It is very effective for soil nutrient imbalance, can meet the nutritional needs of crops throughout the growth period, has a wide range of applications, and a balanced supply of nitrogen, phosphorus, and potassium promotes rapid and thick green leaves, balanced growth of roots and stems. Prevent crop growth, balance nutrition, increase yield and enhance quality.
2. High-nitrogen water-soluble fertilizer
It can regulate the coordinated development of crop vegetative growth and reproductive growth, and enhance the ability of crops to resist adversity.
3. High-phosphorus water-soluble fertilizer
Can effectively promote crop root growth, flower bud differentiation, preserve flowers and fruits, and increase fruit setting rate
4. High potassium water-soluble fertilizer
It is suitable for use after the crops have set fruit. It can reduce fruit drop, reduce deformed fruit, make the fruit size uniform, fast swelling, fast coloring, smooth and shiny skin, increased sweetness, and can improve the quality while increasing the yield.

1. Strong water solubility
It can quickly dissolve in water and is easier to be absorbed by crops, and its absorption and utilization rate is relatively high. More importantly, it can be used in facility agriculture such as spray irrigation to realize the integration of water and fertilizer, and save water, fertilizer and labor. The effectiveness of.
2. Balanced ratio
The total content of macroelements is not less than 50%, and the content of single macro elements is not less than 4%. The balance of the various element ratios required by plants can fully meet the needs of agricultural producers for high-quality and high-stability products.
3. Easy to be absorbed
Trace elements are present in the product in chelated form, which can be fully absorbed by crops.
Four, safety and environmental protection
The raw materials are pure, free of impurities, safe and environmentally friendly.
The macro-element water-soluble fertilizer can be divided into balanced, high-nitrogen, high-phosphorus, high-potassium and special fertilizers according to the different proportions of its elements.
