"four look and four don't" buy chemical fertilizer in autumn seed.

In autumn, with the harvest of summer crops, people are about to face the arrival of autumn wheat, which also means that it is time for farmers to buy chemical fertilizer. Nowadays, there are many kinds of chemical fertilizers in the agricultural materials market, and there are both advantages and disadvantages. Some vendors wantonly advertise their chemical fertilizers, causing certain misunderstandings for farmers to choose and purchase chemical fertilizers. Here, the editor reminds everyone to do "four looks and four don't" when choosing and purchasing chemical fertilizers.

The "four looks" are as follows: first, look at the business qualifications of chemical fertilizer operators and whether they have legal procedures such as a business license to operate chemical fertilizer. Try to choose shops or enterprises with legal procedures, scale and reputation to buy. Second, look at the product certificate, fertilizer inspection list, and ask for the purchase and sale certificate (in case of fertilizer quality dispute). Third, look at the fertilizer label, distinguish the types and properties of fertilizer, and understand the nutrient content, use, usage and matters needing attention of fertilizer. The national standard GB18382-2001 (fertilizer labeling content requirements) stipulates that fertilizers must indicate the content of total nutrients (only N+P2O5+K2O), and shall not add medium, trace elements or organic matter to the total nutrients. However, during the inspection, the relevant departments found that there are still enterprises adding medium, trace elements or organic matter to the total nutrients to deceive consumers. Peasant brothers should pay attention to this situation. Also note that when compound fertilizers are marked with chlorine or chloride ions, they should not be used or used cautiously on taboo crops such as tobacco. Use on seedlings should be kept away from the roots to avoid burning seedlings. Fertilizers marked with nitrate nitrogen should be used cautiously in paddy fields to avoid loss of nitrate nitrogen. Fourth, to see whether the fertilizer enterprises have gone through the relevant formalities. For example, the use of foliar fertilizer, microbial fertilizer to apply for the Ministry of Agriculture fertilizer registration certificate; the use of compound fertilizer, organic fertilizer to apply for provincial fertilizer registration certificate, the use of compound fertilizer also need to apply for production license and so on.

The "four don't" are: first, don't be cheap, regardless of quality, buy fake and shoddy fertilizers, so as not to cause unnecessary losses. There is confusion in the labeling of many chemical fertilizers, and there are many fake products, so we should pay more attention when buying them. Second, don't look at "big" rather than "small". In order to show off the selling points, some products are marked in big words on the packaging, while in order to cope with the inspection of the supervision department, the substance is marked in small print. For example, the words "Russia" are marked in large characters and "raw materials" are used in small characters, which makes people mistaken for imported products; others mark "potassium sulfate" in prominent positions and "chlorine" in inconspicuous places. in order to disturb the audio-visual. Third, don't be fooled by new concepts. Under the guise of high technology, some products make a fuss on packaging, marked with high-tech names such as "biology", "activation" and "green", which are actually general products. Fourth, don't think of yourself as "bad luck". If it is found that there is fertilizer damage in the use of fake chemical fertilizer, it should be reported to the local agricultural competent department, technical supervision department, industrial and commercial department and consumer association in time.
