Product Characteristics:

High Microbial Activity: Effective viable bacteria count (*Bacillus subtilis*) ≥ 5.0 × 10⁸ CFU/g; salt- and heat-tolerant, exhibiting strong stress resistance and rapid proliferation.

Comprehensive Nutrition: Total nutrients ≥ 8.0%, organic matter ≥ 60.0%, protein ≥ 24.0%, amino acids ≥ 6.0%, and Ca+Mg ≥ 5.0% (preventing nutrient deficiency symptoms); provides a balanced blend of fast-acting N-P-K and long-lasting organic nutrition.

Slow-Release & Stable: Features high granule hardness to prevent pulverization; disintegration time ≤ 5 minutes, facilitating mechanized application and ensuring long-lasting fertilizer efficacy.

Safe & Eco-Friendly: Free from pathogenic bacteria; heavy metal levels are below national standard limits; safe and beneficial for both crops and soil.

Functional Benefits:

Root Promotion & Seedling Strengthening: Produced via deep fermentation of plant and animal-derived materials; contains humic acids, amino acids, and natural auxins to stimulate root development and nutrient uptake.

Biological Disease Control: *Bacillus subtilis* effectively prevents and controls soil-borne diseases such as damping-off, root rot, and stem base rot; demonstrates a suppression rate of ≥ 65% against bacterial wilt and can delay leaf senescence by up to 15 days.

Holistic Nutrition: Total nutrients ≥ 8%, organic matter ≥ 60%; rich in amino acids, crude protein, macro/micro-elements, and vitamins, satisfying the nutritional requirements of crops throughout their entire growth cycle.

Soil Improvement: High organic matter content promotes the formation of soil aggregate structures; alleviates soil acidification, salinization, and compaction; enhances water retention and aeration capabilities; and helps overcome obstacles associated with continuous cropping. Stress Resistance & Quality Enhancement: Facilitates nitrogen fixation, phosphorus solubilization, and potassium mobilization; enhances drought and cold tolerance; improves the sugar-to-acid ratio and Vitamin C content; promotes uniform fruit coloration; and extends shelf life.

Eco-friendly & Safe: Free from heavy metal additives; complies with the GB38400-2019 standard; suitable for use in green and organic agriculture.

Suitable Crops:

Cash Crops: Solanaceous fruits (tomatoes, peppers), leafy vegetables, cucurbits (cucumbers, watermelons).

Field Crops: Maize (corn), rice (requires supplementation with nitrogen fertilizer).

Grain & Oil Crops: Potatoes, sweet potatoes, peanuts, cotton.

Fruit Trees: Citrus, apples, peaches, strawberries, bananas, grapes (reduce dosage by 30% for young trees).

Horticultural Nursery Stock: Flowers, tea plants, turfgrass, and nursery substrate improvement.

Application Instructions:

Base Fertilizer: For open-field vegetables and fruit trees, apply 80–120 kg per *mu* (approx. 667 m²). Application methods include mechanical broadcasting across the entire field, furrow application, spot application, or surface broadcasting; ensure a tillage depth of ≥15 cm.

Top Dressing:

Protected Cultivation (Greenhouse) Vegetables: Apply during the fruiting stage at a rate of 20–40 kg per *mu*; apply via strip application or fertigation (dissolved in irrigation water), with an application interval of 30–45 days.

Fruit Trees: Apply during the fruit expansion stage via circular furrow application, spot application, or surface broadcasting at a rate of 0.5–1.0 kg per tree.

Seedling Cultivation: Thoroughly mix with the nursery substrate at a volume ratio of 1:20–30 to improve germination rates and seedling vigor.

Growth Stages: Apply once during the transplanting stage and once during the fruit expansion stage.

Precautions:

Compatibility Restrictions: Avoid direct mixing with copper-based preparations, fungicides (such as streptomycin), or pesticides with strong acidic or alkaline properties (allow an interval of ≥7 days between applications).

Soil Suitability: Exercise caution when using calcium nitrate on saline-alkali soils (EC ≥4 mS/cm). For saline-alkali soils or fields suffering from continuous cropping obstacles, it is recommended to increase the dosage by 20–30%; combining this with deep plowing yields superior results. Post-Application: Maintain soil moisture for 7 days to facilitate microbial colonization. For sandy soils, apply in small doses over multiple intervals; for heavy clay soils, increase the application rate as appropriate and incorporate deep plowing.

First-Time Use: A small-scale trial is recommended to confirm compatibility before widespread application.

Storage Requirements: Store in a cool, dry place away from direct light, at a temperature of ≤30°C and a humidity of ≤60%. Once opened, use the product within 48 hours.
