First, it depends on whether the seed packaging is standard. Regular qualified seeds have labels attached to their packaging, indicating the seed category, variety name, registered trademark, place of origin, quality indicators, quarantine certificate number, seed production license number or import approval number, seed approval number, production Batch number, production date, expiration date and precautions, etc.

Second, it depends on whether the seeds have been coated and whether the outer packaging is complete, standardized, unified and clear.

Third, look at the quality of the seeds. If they are uncoated seeds, choose seeds with bright colors, full particles, uniformity and no impurities.

Four. It depends on the credibility of the business unit. When buying seeds, don't be greedy for cheap. Buy seeds from regular seed companies or relatively fixed seed sales stores with a seed sales power of attorney.

Fifth, it is technical consultation. Ask about the characteristics of the varieties, cultivation techniques, etc.

Sixth, no matter where you buy seeds, you must ask for the purchase receipt from the seller.
