Positioning:

The compound fertilizer integrated with intelligent controlled release nitrogen and photosynthetic optimization technology in the "Songdao" series is mainly used to improve nitrogen utilization efficiency, enhance fruit quality and yield. ‌

Effect:

1. Extended fertilizer efficiency: Long term nitrogen stabilization technology significantly improves nitrogen fertilizer utilization efficiency and reduces loss and waste.

2. Precision quality improvement: Manganese synergistic technology directly affects the intrinsic quality of fruits.

3. Five dimensions of synergy: from flowering to leaves, from nutrient supply to photosynthetic transformation, forming a complete closed-loop system for improving yield and quality.

4. Stable yield increase: By extending nitrogen efficiency and promoting photosynthesis, a dual guarantee of stable high yield is achieved.

5. Suitable for premium agriculture: particularly suitable for economic crops with high quality requirements, such as trees, vegetables, high-value field crops, etc.

Function Description:

1. Long term nitrogen stabilization technology (LNS): Adding efficient nitrification inhibitor DMPP (100-1000 ppm) to selectively inhibit nitrifying bacteria in soil and slow down the conversion of ammonium nitrogen to nitrate nitrogen. This allows nitrogen to exist in ammonium form for a longer period of time, effectively extending the fertilizer efficiency period by about 30% -50% and reducing leaching losses.
2. Boron Efficiency Health Technology (BER): Boron element (≥ 200 ppm) is the key to cell wall construction and the "commander" of sugar transport, ensuring smooth elongation of pollen tubes and fruit setting rate during flowering period.
3. Zinc coenzyme technology (ZFC): Zinc element (≥ 200 ppm) serves as a cofactor for enzymes, participating in the synthesis of auxin precursor "tryptophan", effectively improving apical growth inhibition and enhancing stress resistance.  
4. Iron based chlorophyll technology (IBC): Chelated iron (≥ 200 ppm) is used to ensure the normal operation of electron transfer, the core process of photosynthesis. It forms the core part of the "conductor" (cytochrome) and "switch" (ferritin) in chloroplasts.
5. Manganese Stable Synergistic Technology (MSC): Manganese (≥ 200 ppm) optimizes the stability of photosystem II and enzymes in the photosynthetic system, further stabilizing the performance of the "energy factory" and promoting the conversion of photosynthetic products into fruits, ultimately improving fruit quality (such as sugar content) and overall yield.
