The mineral elements necessary for agricultural production are a large number of elements, medium elements and trace elements. Crops need not only nitrogen, phosphorus, potassium, but also trace elements in chelation, but not all trace elements need to be chelated. Today, Wu Lishu, a professor at the School of Resources and Environment of Huazhong Agricultural University, exposes the "secret" of the sequestration of trace elements. Current status of fertilizer application in China A large number of elements: N, P, K deficiency; medium and trace elements: generally lacking, the impact is serious. Medium and trace elements have become the main limiting factor, and the lack of medium and trace elements is very common. The mineral elements necessary for agricultural production include a large number of elements, medium-sized elements and trace elements. Crops need not only nitrogen, phosphorus, potassium, but also trace elements in chelation. There are medium-sized elements that are easily lacking in agricultural production: silicon, calcium, and magnesium. The trace elements are: zinc, boron, iron, and manganese. The role of medium and trace elements: improve yield, improve quality, nutrients, appearance, color, taste, nitrate content, and improve resistance. The effect of medium and trace elements: Generally, increasing production by more than 10% is not a problem. The ratio of production to investment can reach 1:10. If there are symptoms visible to the naked eye, it can increase production by more than 20%. The current development trend of the world - quick combination Nanotechnology: Nanotechnology is a new technology born in the late 1980s. It is a new technology for studying the laws and characteristics of electrons, atoms and molecules in the space of 0-10 to 100 nanometers (ie, one billionth of a meter). Nanomaterials refer to ultrafine materials with a grain size of nanometers. Nanomaterials have basic characteristics such as small size effect and surface interface effect. The peculiar physical, chemical, and mechanical properties that have been exploited using nanomaterials. Suspension technology: As a highly concentrated liquid fertilizer, suspended fertilizer is the late product of liquid fertilizer, and it is composed of two types of liquid fertilizer. Clear liquid fertilizer refers to a liquid fertilizer with clear or transparent appearance. The clear liquid fertilizer has many advantages of liquid fertilizer. However, there is also a big disadvantage of clear fertilizer, that is, the nutrient content is relatively low, and the mature foreign clear The liquid fertilizer formula has a nutrient content of between 15% and 25%. This limits the transport distance of the clear fertilizer. Therefore, clear fertilizers can only be distributed nearby. Plasma technology: Plasma, also known as plasma, is an ionized gas-like substance composed of positive and negative ions generated by ionization of atoms and atomic groups after partial electrons are depleted. The macroscopic electrical neutral ionization is larger than the Debye length. Gas, its motion is mainly dominated by electromagnetic forces and exhibits significant collective behavior. It is widely found in the universe and is often regarded as the fourth state in which matter exists except for solid, liquid, and gas. Plasma is a good electrical conductor that captures, moves, and accelerates plasma with a well-designed magnetic field. Chelation of trace elements Why activate (chelating): use organic compounds to wrap zinc so that it does not easily lose activity, metal elements fail in fertilizers: precipitation; metal elements fail on plant leaves: oxidation - such as iron; metal elements in solution Medium failure: precipitation, hydrolysis; failure of metal elements in the soil: precipitation; failure of metal elements in plants: precipitation. Phosphorus deactivates medium and trace elements. Phosphorus in soil or a large amount of phosphate fertilizer often leads to or aggravates the zinc deficiency of crops. However, the existing compound fertilizer plant simply mixes the inorganic salts of various elements in proportion. , completely ignore the side reactions between the elements. Although this adds a lot of trace elements, it can be effectively absorbed by crops. Not all trace elements need to be chelated: related to the type of element - the element next to the gold word, one type: unaffected: magnesium, the second type: elements with little influence: molybdenum, three categories: elements with greater influence : Zinc, copper, manganese, four categories: elements with serious effects: calcium, iron. Composite technology: multiple types: not only lack one element; multiple forms: fast and slow combination. Add technology (new way): water soluble fertilizer; organic fertilizer; compound fertilizer (TE); soil conditioner; pesticide (drug fertilizer).
