First, how to identify and guard against counterfeit seeds (1), inferior seeds: whose quality is lower than the national seed standard; if the quality is lower than the labeling index, the rate of weed seeds exceeds the prescribed level because the deterioration cannot be used for seed use.
Qualified seeds: The national standard germination rate is above 85%; the standard germination rate of the package is greater than or equal to 90% (labeled on the package).
(2) Matters needing attention when purchasing seed:
1, witness: business license a subsidiary company;
2. Look at the packaging: crop types, species names, producers, national indicators, seed operating license numbers, net content, and production dates. Bulk seeds (size, size) are not purchased as much as possible.
3. Invoice: Must be invoiced at the time of purchase. After the seeds are purchased, the seeds must be properly preserved. The seeds should be protected from poisoning. The seeds should be used strictly in accordance with the cultivation measures and conditions of use provided by the seed operator.
(c) What to do if there is a problem
1. Retention: Keep evidence such as purchase invoices and seed packaging to protect the site.
2. Report: Report to the Consumer Association of the Agriculture Department to find out the reasons for identification.
3. Solution: Negotiate with the operator, ask the relevant departments to mediate, invite the arbitration agency to arbitrate, and sue to the people's court.
Second, the true and false identification of chemical fertilizers Various fertilizers have a standardized logo, a special external shape, and different physical and chemical properties. According to the observations of fertilizer packaging and appearance observations, the changes in water-soluble, alkali-adding, and burning in the case of fire can be used to determine the type and true and false of the fertilizer. To know if the nutrient content meets the product standard, it must be sampled and tested.
The simple identification method for chemical fertilizers is summarized as follows: see, touch, smell, burn, and wet.
(a), see: 1, to see fertilizer packaging, regular manufacturers of packaging specifications, strong, generally note the trademark, product name, nutrient content, net weight, plant name, site and so on.
Counterfeit fertilizer: rough packaging, unclear packaging bags, poor quality and easy to leak.
2, to see particle size: nitrogen and potassium are mostly crystal, superphosphate is mostly porous block, uniform particle size, surface smooth, easy to absorb moisture or agglomeration.
3, color: different fertilizers have different colors, nitrogen fertilizer (except carbon and nitrogen) more white.
(B), touch: on the palm of your hand, firmly hold or press the rotation, including to judge, such as the United States diamine, force grip several times, there is "oil wet" sense of authentic, and dry as possible may use flip-chip Feifei posing.
(C), smell: fertilizer odor to judge, such as ammonium bicarbonate has a strong hydrogen odor, superphosphate has a sour taste, fake fertilizer smell is not obvious.
(D) Burning: Heating or burning, identified from flame color, melting condition, smoke taste, residue, etc. Such as ammonium bicarbonate, direct decomposition, a lot of white smoke, there is a strong ammonia smell, no residues of potassium, potassium sulfate, magnesium sulfate, magnesium, no change in the wood on the release of sound.
(E) Wet: Dissolve in the water to distinguish: such as ammonium nitrate, potassium sulfate, potassium chloride, etc. completely dissolved or have a little residue. Counterfeit fertilizers are poorly soluble or do not dissolve at all (except for phosphate fertilizers).
Qualified seeds: The national standard germination rate is above 85%; the standard germination rate of the package is greater than or equal to 90% (labeled on the package).
