Pay attention to the nutrient content indicated. What is the “content strip� Quality supervisors told reporters that the nutrients needed for plant growth include three main nutrients, minor nutrients and micronutrients. In general, the production cost of a nutrient is about 30 yuan. Because the current identification of fertilizer components is difficult, consumers can't identify them with the naked eye. Therefore, many unscrupulous enterprises have started the idea of ​​“nutrients pumping†and made a fake on the product identification. For example, it is clear that the active ingredient is less than 10%, but the product packaging indicates that the nutrient content is 80%.
Fake packaging is rough. Can farmers friends identify true and fake fertilizers? The answer is yes. The quality supervisors warned everyone that before buying, you must first check whether the operator has a fertilizer registration certificate, business license, and then check the true and false of the product through the eyes, ears and nose.
According to the regulations, the product name, nutrient content, grade, trademark, net weight, standard code, factory name, factory address, production license number and other signs must be indicated on the packaging of the fertilizer. Most of the packaging of counterfeit and degraded fertilizers uses inferior materials, which are rough, do not meet specifications, have high breakage rates, are unclear, and have a blurred trademark. For the purpose of promotion, the instructions on the packaging of counterfeit and shoddy products generally do not use Chinese characters, and use Pinyin, which is not clearly marked with the place of origin and the manufacturer.
By reading and listening to the identification of chemical fertilizers can also be identified by "seeing the real thing": the real fertilizer particles are round and uniform in size, the fake fertilizers generally have different particle shapes, and the granules are severe; by "seeing the volume to weight": true fertilizer The specific gravity is larger than the fake fertilizer, the same heavy fertilizer, the real fertilizer is small, and the fake fertilizer is bulky; through the "smell": the liquid with strong pungent ammonia smell is ammonia water, and the particles with obvious ammonia odor are ammonium bicarbonate. The sour fine powder is heavy superphosphate. If the superphosphate has a very pungent and sour taste, it means that the waste sulfuric acid is added in the production process. This chemical fertilizer is very toxic, and it is easy to damage or burn the crop. By "listening": grab a handful of fertilizer from high Let go of the hand, let the fertilizer fall freely, the sound of the landing is sharp, and it is fake fertilizer; the sound is heavy, it is the real fertilizer.
