Positioning:

The "Songdao" series of entry-level products aims to provide crops with basic nutrients of nitrogen, phosphorus, and potassium, and to solve the problems of insufficient flowering and poor growth with targeted economic and efficient compound fertilizers.

Effect:

1. Precise ternary synergy: boron is the main "stabilizing flowers", zinc is the main "strengthening plants", and iron is the main "green leaves". The three aspects of crop structure, growth regulation, and energy production build a strong growth guarantee.

2. Overcoming the problem of high pH: The unique chelated iron technology ensures that iron can still be effectively absorbed by crops in alkaline or calcareous soils, making it a powerful weapon for preventing iron deficiency in yellow leaves in high pH areas.

3. Fertilizer efficiency release matches crop demand: High tower granulation ensures a more balanced nutrient release rate, which can better meet the strong demand of crops during critical growth periods. Full process escort: from promoting root absorption (zinc) to ensuring efficient work of middle and upper leaves (iron), and finally to flower and fruit development (boron), achieving full coverage of the growth cycle.

Function Description:

1. Boron Efficiency and Robust Technology (BER): Boron (≥200 PPM) directly participates in building strong cell walls and acts as the "dispatcher" for sugar transport within plants. During flowering, it provides biological momentum for the smooth elongation of pollen tubes, ensuring flower protection and preventing drop.
2. Zinc Coenzyme Technology (ZFC): Zinc (≥200 PPM) acts as a coenzyme, deeply involved in driving a series of biochemical reactions. It particularly promotes the production of auxin precursor tryptophan, thereby addressing issues of slow growth and insufficient stress resistance.
3. Iron-Based Chlorophyll Technology (IBC): Utilizing highly efficient chelated iron (≥200 PPM) to prevent precipitation in high-pH soils. Iron serves as a crucial "metal component" in the electron transport of photosynthesis. Once absorbed, it enters chloroplasts and forms the core parts of the "conductor" (cytochrome) and "switch" (iron-sulfur protein). Through these components, iron ensures efficient electron transfer, providing continuous driving force for the "factory" of photosynthesis. Without sufficient iron, chloroplasts cannot effectively convert light energy into chemical energy.
