3. Closed Production Process & High-Tech Control
Sweet Pepper F1 seeds are cultivated in Lam Tai's modern closed greenhouse system, strictly complying with the following technical standards:
3.1. Seed soaking & Seedling nurturing
Original seeds upon receipt are soaked and treated with specialized chemicals (soaked in warm water at 40°C for 2 hours, treated with 10% TSP for 1 hour) to completely remove pathogens on the seed coat.
Seeds are sown into 100-hole trays sterilized with 10% Javen.
Seedlings are regularly cared for in the nursery for 30 - 35 days before being transferred to larger net houses for planting.
3.2. Safe biological cultivation environment
-
Net house sterilization: Before planting, the entire water trough system, hanging wires, tools, and greenhouse are thoroughly cleaned and sterilized with 2% Virkon and the drip irrigation system treated with 10% HCl acid.
-
Automatic nutrition: Applying drip irrigation technology continuously controlling EC index, pH level, and water supply suitable for each growth stage of the pepper plants.
-
Cross-infection prevention: Caretakers trimming branches must strictly wear gloves and sterilize with 0.1% Physan solution or 0.2% Virkon after each plant to minimize the spread of harmful viruses (such as TMV virus transmitted by thrips).
3.3. Strict manual breeding technique (Male sterility & Pollination)
-
Pollination stage: Begins when the sweet pepper plants reach about 40 days old.
-
Flower emasculation (Male sterility): Trained workers remove all petals and anthers of the maternal flower while still in bud form. Ensuring compliance with the rules: No flower thinning, no emasculating blooming flowers, no leftover pollen sacs, and continuous sterilization of tweezers.
-
Pollination (Pollination): Manual pollination by transferring pollen from the paternal line to the stigma of the maternal flower under controlled environmental temperature suitable for each variety (usually about 28°C). Using colored wool and zinc to accurately mark the pollination date.
-
Pollination duration: The pollination process occurs continuously and completes within about 15 - 20 days.
3.4. Fruit care & Seed harvesting
After pollination ends, plants are supplemented with Potassium and Calcium to nurture the fruit and all open-pollinated (OP) flowers are removed to ensure absolute purity of F1 seeds.
The process of harvesting ripe fruit, seed separation, wastewater treatment, and export packaging is standardized according to SOP, KPI procedures and integrated management on ERP software for production history traceability.
