In recent years, the supply of agricultural products in China has gradually become more abundant, but at the same time, the phenomenon that “the vegetables are tasteless, the melons are not sweet, and the fruits are not fragrant†often appear. Some people think that it is caused by the application of chemical fertilizers, and then it is suggested that organic fertilizers and farmyard fertilizers should be used instead of chemical fertilizers. Some experts believe that this understanding is biased.
The technicians of some large-scale fertilizer plants in Shaanxi Province pointed out that chemical fertilizers are fertilizers produced by chemical methods from various mineral resources, as well as air and water. Fertilizers can improve and improve the quality of crops. For example, nitrogen is the main component of proteins and nucleic acids, and proteins are the basic substances that make up the protoplasts of plant cells. Nitrogen is also a component of chlorophyll. Phosphorus is a constituent element of important organic compounds in plants. Phosphorus is contained in nucleic acids, nuclear proteins, and phospholipids. Potassium can increase the content of chlorophyll and promote the assimilation of carbon dioxide and the transportation of photosynthesis products. Regardless of people's prejudice against fertilizers, they still cannot leave fertilizer. China and the United States, Israel and other countries are large countries in the use of fertilizers.
Now people reflect that the phenomenon of “no taste, no sweetness, no fruit†is not because of the use of chemical fertilizers, but because of the incorrect use of chemical fertilizers. Studies have confirmed that unfertilized fertilization, unreasonable rationing, and indiscriminate fertilization are the root causes of the decline in the quality of agricultural products. For example, some farmers use excessive amounts of nitrogen fertilizer, causing crops to grow wild and boring; some fruits should use potassium sulfate. If the compound is used with potassium chloride compound fertilizer, the acidity will increase and the quality will decrease.
As for the application of organic fertilizer and farmyard manure to replace chemical fertilizers, although the disadvantages of unreasonable application of chemical fertilizers can be avoided, it is often difficult to meet the comprehensive and sufficient nutrient requirements of crops, and the ratio of nitrogen, phosphorus and potassium in organic fertilizers and farmyard manures is very different. Meet the requirements of balanced fertilization. It is also considered that the farmer's fattening must be green food. For example, the vegetable farmers will pour the organic fertilizers such as soup and manure on the vegetables, and soon they will be sold on the market. Although such dishes taste good, they are likely to bring There are germs that cannot be washed away.
