1. Main problems and identification methods of fertilizer packaging label

Fertilizer packaging label is one of the important factors to attract farmers' attention and decide their purchase behavior. Therefore, the relevant state departments pay special attention to the standardization of fertilizer packaging label and released the national standard GB18382－21 "Contents and Requirements of Fertilizer Labels".

Before buying, first look at the packaging label, which mainly includes:

1. Fertilizer name and trademark. The name of fertilizer is not allowed to have exaggerated language;

2. nutrients or total nutrients. Single fertilizer should indicate the percentage content of single nutrient, compound fertilizer should indicate the percentage content and total content of N, P2O5 and K2O, as well as items that should be separately indicated according to product standards, such as chlorine-containing and citric acid-soluble phosphorus. According to national regulations, elements or compounds other than nitrogen, phosphorus and potassium shall not be recorded in the total nutrients;

3. Product standard number. National standard GB, industry standard HG of Ministry of Chemical Industry, industry standard NY of Ministry of Agriculture;

4. production license number;

5. fertilizer registration certificate number;

6. Name of production or distribution unit;

7. address and contact number of the production or distribution unit.

if the packaging label is incomplete or missing, such as the name and address of the enterprise, it should be registered without registration number, etc.; Or exaggerated language, such as high-efficiency * * *, * * king, * * * treasure, * * * spirit, magic * * * and other fertilizer names; Or record other components that should not be labeled as total nutrients, such as fertilizers containing organic matter and medium and trace elements, which are labeled as N+ P2O5+K2O+ organic matter ≥65%, N+P2O5+K2O+ medium and trace elements ≥45%, etc. Packaging products with small font for main content, intentionally exaggerated additional content, and production license or registration number that should not be marked should be purchased carefully.

the packaging is woven bag, the inner packaging is plastic bag, the packaging bag is sewn by machine, and the seams should be neat and consistent. The state stipulates that the packaging bag should be marked with trademark, fertilizer name, manufacturer, fertilizer composition (indicating the content of nitrogen, phosphorus and potassium and the content of added trace elements), product net weight and standard code, and each batch of products should be accompanied by quality certificate. Calcium superphosphate is available in bulk, but it must be accompanied by factory certificate. Excuse me, how to tell the true and false of chemical fertilizer

We can tell the true and false chemical fertilizer by five simple methods: "seeing, touching, smelling, burning and dissolving".

first of all, look. First of all, look at whether the outer packaging of fertilizer is standardized and clear, and whether it is marked with information such as production license, implementation standard and nutrient content. At the same time, it depends on whether the fertilizer particles are uniform and the surface is smooth, while fake and shoddy fertilizers are humid and easy to agglomerate.

the second is "touch", that is, put the fertilizer in the palm of your hand, hold it and rotate it, and judge it according to the feel. For example, diammonium phosphate, grab a handful of fertilizer and hold it hard for several times. Most of them feel "oily" and are genuine, while those that feel dry are likely to be counterfeit. In addition, it can also be judged by "smelling" the smell of fertilizer, for example, ammonium bicarbonate has a bad smell, ammonium sulfate has a sour taste, and the smell of fake and shoddy fertilizer is not obvious.

In addition, if the sample of chemical fertilizer is heated or burned, it can also be judged from the color, smoke smell and residue of the flame. For example, when nitrogen fertilizer is burned, it will emit white smoke and smell of ammonia. There will be no change after phosphorus fertilizer is burned, and there will be crackling noise after potassium fertilizer is burned. Finally, the fertilizer can be dissolved in water. If it is genuine fertilizer, it can be well dissolved in water. How does COCOVEL verify the authenticity?

Hello:

Because there are knockoffs, parallel imports, clones, etc. in the market, the IMEI number of the mobile phone can be changed by means of brushing, so it is impossible to accurately identify the authenticity of the mobile phone only by serial number and IMEI number through the Internet.

if you want to identify whether the mobile phone is licensed in mainland China, please be sure to bring your purchase invoice, repair card and mobile phone, and go to the local Samsung service center to check whether the mobile phone can be repaired. If it can be repaired, it means that it is a licensed mobile phone listed in mainland China. This is the best and most accurate method.

How to verify the authenticity of Danzi cosmetics

Danzi products usually go directly to Dashangchao. If you buy them in big shopping malls or chain stores, the quality can be guaranteed. If you buy it online, you should distinguish it carefully. Danzi official said that no mall was authorized to sell online. So it's hard to say whether it's true or not. How to verify the authenticity of Xtep?

You can basically know the authenticity of shoes when you get them. Here, I will talk about how to prevent buying non-genuine shoes. To sum up, I will sell them as "genuine". (In fact, you can basically conclude from the reply) 1. "We are genuine. Accept the counter inspection. " --(AF1 is lower than 46, so don't think it's true) Except for this, there is no identification, and most goods can't see the monopoly environment. Typically selling a. Monopoly people have nothing to do? Nothing to test the authenticity of people who buy shoes on Taobao? And for example, you are not a counter. If you go to Nike for a summer job, you wouldn't know the difference between true and false. Just go to work. ! A lot of people at the counter don't know. In this case, "accepting counter inspection" is basically (99.9%)= fake genuine goods. 2. "Our shoes are purchased directly from manufacturers, which saves many links in the middle, so it is the first-hand price, which benefits consumers and keeps the price low." -but all the box accessories are complete. You know, if the factory goods flow out like this, can the price be lower? Moreover, manufacturers are not inhuman, and they also have rules that can't break the market, so this sentence is super high-sounding for most stores, which is very funny, and 9% of them sell XXX. 3. "Generally, a pair of shoes will produce 1 million pairs, and a list of 1,3 pairs will be produced. We are the only ones left, and the quality is the same as that of the exclusive products." -99% are those factories that don't want to live, and they ship a large number of goods privately. It's not in the form of B-products. Do you want to punish N 12 million? Typical excuse 4. "Shoes are generally divided into Grade A and Grade B ... (N is omitted in the middle). Traditional genuine goods are monopoly goods from formal channels. We take goods from manufacturers and take out Grade A, and the quality is the same as genuine goods"-a lot of reasons are given to confuse people or sell XXX. 5. "We are the goods of monopoly/counter." -attention ~ ~ ~! This kind of shop has DUNK SB, clover 35th anniversary, which is definitely not genuine, because these shoes are not available in the counter. Reiterate: DUNK is not DUNK SB, these are two concepts. DUNK on the counter, not DUNK SB! 6. "Look at our favorable comments and explain everything." -most of them accept unconditional return, because the profits are rich, and they are found to be a big deal, and they have been safe and sound. On the contrary, it is difficult for those who really sell genuine products to adhere to such conditions. Because they have to bear a lot of patent fees, and the purchase is not cheap. 7. "OEM products, our quality is the same as the genuine ones. ..... "Playing with the concept between" genuine "and" non-genuine ". In fact, the essence is not genuine! Strongly despise this kind of hype. Does OEM have nothing to do? Do you know the daily production process of OEM? You want to say it's genuine. Why do you know that the shoes you received are wrong when you look at the shoe label? Ok, you just said that it was made by OEM. I think OEM has a fever. I have time to make non-genuine shoes for you. OEM is full every day, so I don't know where the manufacturer's process is blowing. For example, NIKE's OEM has to pick up a bunch of samples every day, and then make a lot of samples and send them to local franchises. It's funny that he took the time to make cheap imitation shoes for you ... How much does it cost to sell shoes to NIKE? How much will it cost to sell to you, and then we will cooperate with you to make fake shoes, print a lot of fake shoes and put them in the factory for people to check the fine, right? I made it specially for you. Do you think there is a .1% chance that what you said

remember to adopt it. How can power support verify the authenticity

At that time, I considered buying Power Support Crystal Jacket or Air Jacket. . Crystal Jacket can protect the silver edge (it seems to be) and completely surround it, and the stand on the back is also convenient for watching movies. . But I thought about it for a long time. . . I bought this just to be light and thin, and to show the original side of 3GS. . So be prepared to scratch the silver edge ... how to verify the authenticity of NDSI
