Water-soluble fertilizers, referred to as water-soluble fertilizers, are defined as liquid or solid fertilizers that are dissolved or diluted by water and used for irrigation, fertilization, foliar fertilizer, soilless cultivation, and soaking of roots. As a multi-component fertilizer, water-soluble fertilizer can dissolve quickly in water, and is more easily absorbed by crops. Its absorption and utilization rate is relatively high, and it can solve the nutrient requirement for high-yield crops during the fast growing period. Especially in the facility agriculture, it is combined with micro-sprinkler irrigation and drip irrigation to achieve water and fertilizer integration to achieve water and fertilizer integration. With the increasing shortage of water resources, the application of water-soluble fertilizers has become one of the measures for increasing efficiency and increasing farmers' income. Water soluble fertilizer types and standards Precision turned parts are mainly in six axle lathe with sticks of metal materials finished, such as variety of high precision and quality of electronic, computer precise components, communication components, automotive parts and accessories, machinery parts, sanitation hardware parts, optics precise parts, medical appliances, pneumatic tools accessories.

Water-soluble fertilizers can be divided into a large number of elements water-soluble fertilizers, trace elements water-soluble fertilizers, water-soluble fertilizers containing humic acid, water-soluble fertilizers containing amino acids, etc. The Chinese agricultural industry standards have clear requirements on the quality of related fertilizers.
1, a large number of elements water soluble fertilizer
A large number of nitrogen, phosphorus, and potassium are the main elements. In accordance with the proportion suitable for plant growth, liquid or solid water-soluble fertilizers made of trace elements such as copper, iron, manganese, zinc, boron, molybdenum, or calcium, magnesium are added. The product standard is NY1107-2010. The standard stipulates that the content of macro elements in solid products is ≥50%, the content of trace elements is ≥0.2-3.0%, the content of macro elements in liquid products is ≥500 g/L, and the content of trace elements is ≥2-30 g/L. .
2, the amount of water soluble fertilizer
From the calcium, magnesium medium element in accordance with the ratio suitable for plant growth, or add the appropriate amount of copper, iron, manganese, zinc, boron, molybdenum trace elements made of liquid or solid water-soluble fertilizer. The product standard is NY2266-2012. The technical index of this product is: liquid product Ca≥100g/L, or Mg≥100g/L, or Ca Mg≥100g/L. The solid product Ca ≥ 10.0%, or Mg ≥ 10.0%, or Ca Mg> 10.0%. This standard was formally implemented on June 1, 2013.
3, trace elements water soluble fertilizer
A liquid or solid water-soluble fertilizer made from trace elements of copper, iron, manganese, zinc, boron, and molybdenum in proportions suitable for plant growth. The product standard is NY1428-2010. The standard provides that the trace element content of solid products is ≥10%; the trace element content of liquid products ≥100g/L.
4, with amino acid water soluble fertilizer
With free amino acids as the main body, according to the proportion required for plant growth, liquid or solid water-soluble fertilizers made of copper, iron, manganese, zinc, boron, molybdenum trace elements or calcium, magnesium intermediate elements are added. There are two types of calcium. The product standard is NY1429-2010, and the free amino acid content of trace element type amino acid-containing water-soluble fertilizer is not less than 10% and 100g/L for solid and liquid products respectively; the total content of at least two trace elements is not less than 2.0% and respectively. 20g/L. Calcium type amino acid-containing water-soluble fertilizers are also available in both solid and liquid products. The indicators are the same as the trace element types. Only the calcium content, solid and liquid products are not less than 3.0% and 30 g/L, respectively.
5, with humic acid water soluble fertilizer
Water-soluble fertilizer containing humic acid is a water-soluble fertilizer containing humic acids. To meet the proportion of humic acid required for plant growth, add a suitable amount of nitrogen, phosphorus, potassium or copper, iron, manganese, zinc, boron, molybdenum trace elements made of liquid or solid water-soluble fertilizer. Humic acid is a class of natural organic macromolecules formed by the decomposition and transformation of organic substances such as animal and plant residues and geochemical processes. It is extracted from peat, lignite and weathered coal, which can stimulate plant growth, improve soil fertility, and improve Nutrient availability and crop resistance. The product standard is the agricultural industry standard NY1106-2010. According to product standards, the humic acid content of a large number of elemental solid products is not less than 3%, and the content of a large number of elements is not less than 20%; the humic acid content of a large number of elemental liquid products is not less than 30g/L, and the content of a large number of elements is not lower than 200g/L; the humic acid content of the trace element solid product containing humic acid is not less than 3%, and the trace element content is not less than 6%.
