With the widespread popularity of water-soluble fertilizer in the country, more and more people choose to use water-soluble fertilizer when topdressing, water-soluble fertilizer manufacturers are too many, they say that their products are good, but where they do not know, I believe that many people also have such doubts, today to tell you about the role of a large number of elements of water-soluble fertilizer and Saint one, water-soluble fertilizer is what?
Water soluble fertilizer It can be dissolved in water, referred to as water soluble fertilizer. Its form is divided into liquid and solid, often used in drip irrigation, spraying, flushing and so on. The ratio of nitrogen, phosphorus and potassium contained in the water-soluble fertilizer provides nutrients for crops in different periods according to its different formula. Compared with other large fertilizers, the water-soluble fertilizer has a faster absorption rate and a more reasonable formula, and is often used for crop topdressing.

Second, a large number of elemental water-soluble fertilizers are generally divided into: high nitrogen type, high phosphorus type, balance type, high potassium type.

1, high nitrogen type large amount of element water soluble fertilizer
Generally, in the early use of crops, the role of nitrogen fertilizer can accelerate seedling extraction, strengthen roots and promote roots, it can speed up photosynthesis, promote the synthesis of chlorophyll in crops, and make plants grow more robust. Provide nutrients for crops in the early stages of the plant.
2. Balanced water-soluble fertilizer with a large number of elements
The ratio of nitrogen, phosphorus and potassium contained in the balanced water-soluble fertilizer is the same, and the ratio of the common balanced water-soluble fertilizer is 17-17-17 or 20-20-20. The balanced fertilizer is generally used in the early and middle stages of crops, and the ratio of nitrogen, phosphorus and potassium is more scientific, which reserves enough energy for the fruit hanging in the later stage of crops and effectively promotes the growth and development of leaves and roots.

3, high phosphorus type large amount of element water soluble fertilizer
High phosphorus type large amount of element water-soluble fertilizer is mainly used in the pre-flowering or post-flowering stage of crops. The role of phosphorus can make crops bloom early, it can promote flower bud differentiation, flower preservation and fruit promotion, and lay a solid foundation for crop yield and quality in the later stage.
4, high potassium type large amount of element water soluble fertilizer
Mainly used in the rising period of crops, the role of potassium is to make the fruit more expanded, early color, so that the crop color is better, but also increase the accumulation of sugar, so that the crop fruit, mature earlier.
There are many water-soluble fertilizer manufacturers on the market, it is inevitable that there will be some illegal businesses opportunistic, choose water-soluble fertilizer in addition to looking at the content, water solubility, smell, as the saying goes, "there is comparison only harm", this method is more convincing to the people.
