Fertilizer is the food of plants, and it is an irreplaceable input for agricultural production. It is the carrier of advanced agricultural science and technology and the basis for farmers to increase their income. It determines the quality and output of agricultural products and plays an important role in the development of agriculture. At present, it is the peak season for fertilizer sales, especially the increase in fertilizer prices this year, reminding farmers to pay attention to the following matters when purchasing chemical fertilizers.
First, recognize manufacturers, recognize famous brands. There are many kinds of compound fertilizers in the agricultural capital market, and the quality varies. Generally speaking, large state-owned chemical fertilizer production enterprises have advanced production technology and equipment, strict management, and stable and reliable product quality. In the purchase process, it is necessary to select brand-name products in a targeted manner and correctly select fertilizers for rice, dry land, vegetables, and fruit trees.
Second, look at the packaging content. Complex fertilizer packaging bags should bear the following marks: product name, brand name, nutrient content, total nutrient content, net content, implementation of production standards, production license, fertilizer registration certificate, name of the manufacturer, and site. Each bag of fertilizer should be accompanied by a product certificate or quality certificate, and the date of manufacture or batch number should be indicated on the product certificate, quality certificate or product packaging.
Third, choose suitable for the local soil, crop compound fertilizer. According to the soil nutrient content, the law of fertilizer requirement of crops and fertilizer effect, compound fertilizers with strong pertinence and suitable for soil and crop growth should be selected. Some farmers blindly purchase compound fertilizers that are not suitable for local application. This not only affects the growth and development of the crops, but also causes the waste of individual nutrients and also affects the yield.
Fourth, due to the regular manufacturers' production equipment and production technology are more advanced, the chemical fertilizer products produced have uniform particles, balanced nutrients, and stable quality. The products are developed by experts for long-term experiments on the characteristics of soil nutrient and crop fertilizer requirements. The formula is scientific and reasonable, with strong pertinence, full nutrition, and sufficient content. Therefore, when purchasing chemical fertilizers, consider regular chemical fertilizer products.
Fifth, correct identification of counterfeit fertilizers. A look at the specific gravity of the particles and their smoothness, the ratio is significant or too smooth, the adulteration component is large; Second, look at the production date, the longer the storage time, the total nutrients of fertilizer will gradually reduce; Third, look at the physical properties of compound fertilizer . Compound fertilizer with good product quality, uniform particle size, no agglomeration, no crushed powder; four smells of fertilizer, generally small odor of urea-type compound fertilizer, relatively stable nutrient content, and relatively large odor of ammonium nitrate or ammonium chloride compound fertilizer. The nutrient content is not stable and the use effect is poor. If there are odors such as diesel oil and kerosene, it may be fake chemical fertilizer.
6. Avoid using “double chlorine†compound fertilizers for years. The “Dual Chlorine†compound fertilizer is a compound fertilizer produced with ammonium chloride and potassium chloride as raw materials, with a high chloride ion content. Chloride ions are the trace elements needed for growth and growth. The proper amount can promote the growth of the effect. Excess can cause fertilizer damage. If the “dual chlorine†compound fertilizer is applied year after year, there will be a large amount of chlorine ions in the soil. Absorption of excess chlorine ions will result in “chlorine harm†and “salt damage†will occur in the soil.
7. Referring to the famous fertilizer products promoted by the first fertilizer management and fertilizer information exchange meeting in Zhumadian City. Such as: Zhumadian Zhonghua Fertilizer Industry Co., Ltd. "Hummer Brand" Urea Series Compound Fertilizer, Sinopec Group Nanjing Chemical Industry Co., Ltd. "Red Triangle" Compound Fertilizer, China Arab Fertilizer Co., Ltd. "Sacofu" Brand Compound Fertilizer, Shandong Hongri Arkang Chemical Co., Ltd. "Sunny Day" brand compound fertilizer, Henan Xinlianxin Chemical Co., Ltd. "Heilenxin" brand compound fertilizer and other 20 brand-name products, Zhumadian Soil Fertilizer Utilization Management Station awarded to the Zhumadian City Distributor with a bronze medal. .
Finally, remind farmers friends that when purchasing chemical fertilizers, they must go to a regular sales office and operate a reputable unit. Certainly ask for a shopping invoice in case of a quality dispute as evidence of the complaint. Don't covet cheap, do not talk about quality, cause unnecessary losses; do not be confused by the new concept; it is best to keep a small amount of fertilizer samples after the use of fertilizers, in case of fertilizer quality problems, is an important proof of the claim. The discovery of fake fertilizers or the occurrence of fertilizer damage during use should be promptly reflected to local agriculture, technical supervision, industry and commerce or consumer associations and other departments to protect their legitimate interests.
