Water-soluble fertilizer is a new type of fertilizer that can be completely dissolved in water developed in China in recent years. It is a fertilizer that is soluble in water, such as industrial grade diammonium phosphate, urea, potassium chloride, etc., scientifically proportioned according to a certain ratio, and added boron, iron, zinc, copper, molybdenum and chelated trace elements. The new production process combines a chemical fertilizer that can be completely dissolved in water, and completes fertilization through buried infiltration and drip irrigation, which has the characteristics of high fertilizer efficiency, fertilizer saving, labor saving, and increased yield.
1. Characteristics and advantages of water soluble fertilizer
(1) Total nutrition, full water solubility, easy to absorb
Compared with traditional fertilizer varieties, water-soluble fertilizers have obvious advantages. It is a multi-component compound fertilizer which can be completely dissolved in water. It can be quickly dissolved in water, easily absorbed by crops, and has relatively high absorption and utilization rate. The key is that it can realize the integration of water and fertilizer, and it can be applied to facility agriculture such as drip irrigation. To achieve the efficiency of water saving and fertilizer saving.
(2) Water saving, safe and efficient
Its main features are easy to use, low dosage, water-saving and fertilizer-saving, low cost, fast absorption and high utilization of nutrients. Since the application method of the water-soluble fertilizer is irrigated with water, the fertilization is extremely uniform, which also lays a solid foundation for improving the yield and quality. People can design formulas based on the nutritional needs of crops. The scientific formula does not cause waste of fertilizer, making the fertilizer utilization rate almost 2-3 times that of conventional compound fertilizers.
(3) Quick-acting, controllable and convenient formula fertilization
Water-soluble fertilizer is a quick-acting fertilizer that allows growers to see the effects and performance of fertilizers faster, and adjusts the fertilizer formula according to the different growth and growth stages of the crop.
(4) Easy to apply, save time and labor
The application method of water-soluble fertilizer is very simple. It can be fertilized with irrigation water, including sprinkler irrigation, drip irrigation, etc., saving water and saving fertilizer while saving labor. This is the use of water-soluble fertilizer in the increasingly high labor cost today. The benefits are obvious.
Water-soluble fertilizer has the characteristics of being simple and convenient to use, and therefore it has been widely used in the world. In foreign countries, it is widely used for fertigation of vegetables and flowers in greenhouses, various fruit trees and field crops.
2. What are the classifications of water soluble fertilizer products?
(1) A large amount of elemental water-soluble fertilizer, mainly one or more of nitrogen, phosphorus and potassium. The nitrogen fertilizer may be an organic nitrogen source such as an amide nitrogen fertilizer, an ammonium nitrogen, a nitrate nitrogen or an amino acid. The raw materials may be urea, ammonium nitrate, potassium nitrate, ammonium chloride, amino acids, etc.; the phosphorus source is mainly selected from orthophosphate, metaphosphate, polyphosphate, etc., generally used potassium dihydrogen phosphate, dipotassium hydrogen phosphate, Ammonium phosphate, phosphoric acid and some metaphosphates and polyphosphates; potassium fertilizers are generally selected from potassium nitrate, potassium dihydrogen phosphate, potassium sulfate and the like.
(2) Medium-quantity element water-soluble fertilizer, generally refers to calcium, magnesium, boron, silicon and other ingredients. The calcium fertilizer mainly uses water-soluble inorganic calcium salt and chelated calcium, and the raw material of the product may be calcium chloride, calcium nitrate, calcium ammonium nitrate, calcium acetate and calcium chelated with organic substances such as EDTA, citric acid, amino acid and sugar alcohol; Magnesium mainly uses water-soluble inorganic magnesium such as magnesium chloride and magnesium sulfate; silicon mainly uses sodium silicate as a source. Because it is alkaline and easily reacts with calcium, magnesium, zinc, iron and other ions to form flocculent precipitate, it is generally used alone. .
(3) Functional water-soluble fertilizer, as the name suggests, has a special effect of water-soluble fertilizer. For example, plant growth regulator type water soluble fertilizer, such water soluble fertilizer added gibberellin, naphthalene acetic acid (sodium) and other substances with biological growth regulating function; fertilizer type water soluble fertilizer, such water soluble fertilizer in addition to the nutrients necessary for plant growth In addition to the elements, a certain number of different types of pesticides and herbicides will be added. In addition to promoting the growth and development of crops, it can also prevent the occurrence of pests and diseases, and can usually be divided into special fertilizers for weeding, special fertilizers for sterilization, and special fertilizers for insecticides; In addition, water-soluble fertilizer can also be divided into sea urchin water soluble fertilizer, humic acid water soluble fertilizer, sugar alcohol water soluble fertilizer, alginic acid water soluble fertilizer, amino acid water soluble fertilizer and the like.
Therefore, on the market, whether water-soluble fertilizer can prevent pests and diseases, we already have the answer! Some water-soluble fertilizers do have the effect of controlling pests and diseases, but not all water-soluble fertilizers have significant effects on pest control. At the same time, from another angle, water-soluble fertilizer can directly supplement the nutrients needed for growth, and to a certain extent, it will enhance the resistance of plants, thereby reducing the probability of disease occurrence and effectively reducing the occurrence of physiological diseases.
