Positioning:

The "Songdao" series of entry-level products are cost-effective compound fertilizers designed to provide crops with essential NPK nutrients and specifically address issues such as poor flowering and weak growth. ‌

Effect:

1. Dual-effect Synergy: A single fertilization achieves the dual goals of "comprehensive nourishment (NPK)" and "precise regulation (B+Zn).".

2. Clear Objectives: Specifically designed to address two common yet highly impactful field issues—“flowering without fruiting” and delayed top growth.

3. Cost-effective: Combining multiple functions in one, it significantly reduces the additional time and cost of later micro-fertilizer spraying, with a high input-output ratio.

4. Stable and Reliable: Based on mature ammonification and granulation technology, it features excellent physical properties and stable fertilizer efficacy release, making it suitable for conventional field application.

Function Description:

1. Boron Efficiency and Health Technology (BER): This product contains boron (≥200 PPM), an essential participant in cell wall formation and carbohydrate transport. During the critical flowering window, boron ensures the normal and rapid elongation of pollen tubes, thereby achieving efficient fertilization and significantly reducing empty flowers and fruit drop caused by boron deficiency.
2. Zinc Coenzyme Technology (ZFC): Zinc (≥200 PPM) serves as a coenzyme, directly participating in the catalysis of various biochemical reactions. One of its key roles is involvement in the synthesis of "tryptophan," an amino acid that acts as the direct precursor to plant growth hormones (auxins). Consequently, this technology can effectively mitigate zinc-deficiency-induced apical growth inhibition (such as small leaves and clustered growth) and comprehensively enhance crops' resistance to abiotic stressors like drought and low temperatures.
