Agricultural modernization puts forward higher requirements for chemical fertilizers, and its development trend is high concentration, compounding and specialization. At present, all countries in the world are vigorously developing compound fertilizers, and compound fertilizers have become increasingly important in the production and consumption of chemical fertilizers. Some developed countries may even reach 70%-80%, while the development of China's compound fertilizers started relatively late and currently accounts for only about 20%. Therefore, the development of compound fertilizers is an urgent need for China to accelerate agricultural modernization. The so-called compound fertilizer means that among the three nutrients of nitrogen, phosphorus, and potassium, at least two kinds of nutrients of the indicated amount are fertilizers made by chemical methods and/or blending methods. The product containing two nutrients is called a two-component compound fertilizer, and the fertilizer containing three nutrients is a three-component compound fertilizer. In recent years, some trace element fertilizers have been added to common compound fertilizers, which are called multi-component fertilizers. In addition, some fertilizer products have added pesticides or auxins to traditional compound fertilizers and are called multi-functional compound fertilizers. In China, compound fertilizers are collectively referred to as compound fertilizers and compound fertilizers. Commonly used types may be referred to as chemical fertilizers, mixed compound fertilizers, blended fertilizers, and organic-inorganic compound fertilizers. This article describes in detail the definition, advantages and disadvantages of these complex fertilizers and the problems that should be paid attention to in production and application.
Chemical fertilizer
Chemical fertilizer refers to compound fertilizers that are synthesized through chemical (chemical) action or amination granulation process and are synthesized through obvious chemical reactions. The common types mainly include diammonium phosphate, monoammonium phosphate, nitrate phosphate, and potassium nitrate. And potassium dihydrogen phosphate and so on. This type of compound fertilizer contains the elements needed for two or more crops, has a high nutrient content, can provide a balanced and long-term supply of nutrients needed by the crop, and increase the effect of fertilization and yield increase. Secondly, these compound fertilizers are mostly granular, generally have low moisture absorption, do not agglomerate, and have good physical properties. They can improve the poor quality of certain simple fertilizers and are also convenient for storage, which is particularly conducive to mechanized fertilization. Finally, these fertilizers can be used as fertilizers, basal fertilizers and topdressing fertilizers, and they have a wide range of applications.
However, chemical fertilizers have some disadvantages. For example, the ratio of nitrogen, phosphorus and potassium nutrients is relatively fixed and cannot be applied to nutrient requirements of various soils and various crops. Therefore, in the process of compound fertilizer application, the application of simple fertilizer is generally required to meet the needs of various types of crops for different nutrient types and quantities at different stages of production, so as to achieve the balanced demand of nutrients for high yield of crops. In addition, chemical compound fertilizers are synthesized from different elemental and compound fertilizers through chemical action, so that it is difficult to meet the requirements of different nutrient fertilization techniques in the process of fertilizer application, and the optimum application effects of various nutrients contained therein cannot be obtained.
