Especificações e parâmetros do produto

Core Product Technology: 5-ALA-Based Biological Enhancement Mechanism

This product is refined through a dual-strain synergistic deep fermentation process using proprietary high-yield 5-aminolevulinic acid (5-ALA) producing strains, including Bacillus subtilis and Bacillus velezensis.

5-ALA is a key precursor for the synthesis of porphyrin compounds such as chlorophyll and heme in plants.

Mode of Action

When sprayed during the fruit coloring stage, the live bacteria and their metabolites are rapidly absorbed and continuously provide highly active 5-ALA, thereby helping to:

1. Significantly enhance photosynthetic efficiency and provide sufficient carbon sources for sugar and dry matter accumulation.
2. Efficiently drive the synthesis and transformation of endogenous pigments such as anthocyanins and carotenoids, promoting natural fruit coloration.
3. Work synergistically with abundant metabolites, such as bio-derived astaxanthin and β-glucosidase, to comprehensively improve fruit sugar content, flavor compounds and nutritional value.
4. Gently regulate maturity-related metabolism, promote uniform fruit ripening, and enhance stress resistance and storage tolerance.

Four Core Functional Values

1. Excellent Coloring Promotion for Brighter Fruit Appearance

The product quickly activates the fruit coloring mechanism, promotes uniform, vivid and deep coloration, and significantly improves the commercial appearance of fruit.

2. Higher Sugar Content, Better Quality and Richer Flavor

It comprehensively increases internal quality indicators such as soluble solids, sugar content, free amino acids and vitamins. It also improves fruit shape and promotes the release of aromatic compounds, achieving a combined flavor upgrade with higher sweetness, richer aroma and better overall quality.

3. Earlier Ripening and Longer Storage and Transport Period

The product accelerates the fruit ripening process, helping crops enter the market earlier and capture premium selling windows. At the same time, it enhances fruit firmness and cellular vitality, reduces post-harvest water loss and disease risk, and effectively extends shelf life and storage time.

4. Bio-Based Safety and Wide Applicability

The product is produced entirely through microbial fermentation and contains no chemically synthesized hormones. It aligns with green and ecological cultivation practices.

It is suitable for quality management during the coloring stage of various fruit and vegetable crops, including apple, strawberry, cherry, tomato, grape, peach, citrus and pepper.

Scientific Application Plan

Best Application Timing:
Start application when the fruit enters the early coloring stage, when approximately 5%–10% of the fruit surface has begun to color.

Recommended Dilution Ratio:
Dilute 300–500 times, equivalent to mixing 100 g of product with 30–50 kg of water.

Application Method:
Apply evenly by foliar spraying. Ensure thorough coverage, with leaves fully wetted but not dripping. Fruit surface spraying may also be applied as appropriate.

Application Frequency:
It is recommended to spray twice continuously during the coloring stage, with an interval of 7–10 days, for more stable and pronounced results.

Key Precautions

Avoid mixing with fungicides, copper-based products or similar formulations. Apply separately with an interval of more than 5–7 days.

If rainfall occurs within 24 hours after spraying, re-application is recommended.

Storage Conditions:
Store in a cool, dry and well-ventilated place. Avoid storing together with toxic or harmful substances. Shelf life: 12 months.

Verified Application Results

Case 1: Peach Orchard Application — Earlier Coloring and Higher Sugar Content

Location:
Pengxiang Picking Garden, Daolang Town, Tai’an, Shandong Province

Results:
Compared with the control group, peach trees sprayed with Meitiantian microbial agent, especially those sprayed twice, showed significantly faster fruit coloring. The colored area was larger, the fruit color became deeper red, and the ripening period was noticeably advanced.

Testing showed that fruit sugar content increased by 1–2° Brix, and the fruit flavor improved significantly.

Case 2: Tomato Application — Earlier Ripening, Higher Yield and Better Economic Return

Location:
Xujiazhuang Tomato Base, Culai Town, Tai’an, Shandong Province

Results:
Tomatoes sprayed with Meitiantian microbial agent produced significantly more ripe fruit than both the competing product group and the water control group. The fruit color was bright and vivid, and market readiness was advanced by 3–7 days.

The first harvest already generated increased income, and the input-output ratio per mu was significantly higher than that of competing products with less noticeable effects.
