There are 16 kinds of nutrients for plant growth, namely nitrogen, phosphorus, potassium, sulfur, calcium, magnesium, carbon, hydrogen, oxygen, boron, iron, molybdenum, copper, zinc, manganese, and chlorine, except that carbon dioxide is from the air. Absorption, and the rest need fertilizer to varying degrees to meet the normal growth needs of the crop. Among them, nitrogen, phosphorus, and potassium are a large number of elements, and sulfur, calcium, and magnesium are intermediate elements, and the rest are trace elements. In addition, there are also some beneficial elements such as silicon-containing fertilizers. Although the demand for these elements varies greatly, the role of plants in the growth and development of plants is equally important and cannot be replaced with each other.
Nitrogen Fertilizer: Fertilizers containing nitrogen as the main component, including ammonium bicarbonate, urea, ammonium nitrate, ammonia, ammonium chloride, and ammonium sulfate.
Phosphate fertilizer: Phosphate nutrient elements as the main component of chemical fertilizers, including general through calcium phosphate, calcium magnesium phosphate fertilizer.
Potassium: Potassium nutrients as the main component of the fertilizer, the main varieties are potassium chloride, potassium sulfate, potassium nitrate and so on.
Compound fertilizer: It is a binary compound fertilizer containing three elements (nitrogen, phosphorus, and potassium) of two kinds of fertilizers, and three-element compound fertilizers containing three elements of nitrogen, phosphorus, and potassium. Among them, mixed fertilizers are widely promoted throughout the country.
Trace element fertilizers and some medium-element element fertilizers: The former include fertilizers containing trace elements such as boron, zinc, iron, molybdenum, manganese, and copper, and the latter include fertilizers such as calcium, magnesium, and sulfur.
At present, fertilizers marketed by the market are dominated by NPK fertilizers, and there are also many varieties of each fertilizer. The main nitrogen fertilizers are: urea, ammonium bicarbonate (ammonium carbonate), ammonium chloride, ammonium sulfate, ammonium nitrate, calcium nitrate, ammonia, lime nitrogen, etc. also belong to nitrogen fertilizer, but it has been used less frequently. Calcium nitrate is both nitrogen fertilizer and calcium fertilizer.
The main types of phosphate fertilizers are superphosphate (superphosphate), heavy superphosphate (heavy calcium, also known as double and triple superphosphate), calcium magnesium phosphate, and phosphate rock, steel slag phosphate, defluorinated phosphate fertilizer, and bone meal. It is also a phosphate fertilizer, but it is currently used in very small quantities.
The main potash fertilizers are potassium sulfate, potassium chloride, kiln ash potash and grass ash. Potassium sulfate and potassium chloride components are relatively pure, and most of them rely on imports.
There are also many trace element fertilizer types, the most commonly used boron fertilizer is borax, zinc fertilizer is zinc sulfate, manganese fertilizer is manganese sulfate, molybdenum is ammonium molybdate, copper fertilizer is copper sulfate, and iron fertilizer is ferrous sulfate and some organics. Iron complexes.
The commonly used sulfur fertilizers are: superphosphate, gypsum, sulfur powder, ammonium sulfate, potassium sulfate, zinc sulfate, sulfur-coated urea, and sulfur-containing compound fertilizers.
Nitrogen Fertilizer: Fertilizers containing nitrogen as the main component, including ammonium bicarbonate, urea, ammonium nitrate, ammonia, ammonium chloride, and ammonium sulfate.
Phosphate fertilizer: Phosphate nutrient elements as the main component of chemical fertilizers, including general through calcium phosphate, calcium magnesium phosphate fertilizer.

Fried Food is one of the traditional foods in our country, whether it is fried rice, fried spring rolls, croquettes, or fried dough sticks, oil cakes, noodles, and French fries in children's favorite snacks. Fried bread, fried chicken wings, and fried potato chips and fried biscuits in snacks are all fried foods.
Deep-fried foods are popular among many adults and children because of their crispy taste, aroma, and appetite. However, frequent consumption of fried foods is extremely detrimental to health.
