Differences and association between water-soluble fertilizer and foliar fertilizer, drip irrigation and fertilization

- Mar 28, 2019-

1. Foliar fertilizer: The general foliar fertilizer mainly has the following types: trace element water-soluble fertilizer, large amount of water-soluble fertilizer, amino acid-soluble fertilizer, humic acid-soluble fertilizer, alginic acid-soluble fertilizer, seaweed, etc. The most common foliar fertilizers are potassium dihydrogen phosphate and urea. They all have one thing in common. They are very water-soluble and do not block the nozzles, so they are often used for foliar application.


2. Water-soluble fertilizer is divided into a large number of elemental water-soluble fertilizers, trace elements, amino acid-soluble fertilizers, and humic acid-soluble water-soluble fertilizers. It is a quick-acting fertilizer with good water solubility and no residue. It can be completely dissolved in water. It is directly absorbed and utilized by the roots and leaves of crops. The use of water and fertilizer, water and fertilizer, to achieve water and fertilizer integration, its effective absorption rate is more than double the common chemical fertilizer, reaching 80%-90%; and fast fertilizer efficiency, can solve the nutritional needs of high-yield crops in the rapid growth period . It can be foliar fertilizer, flushing or drip irrigation.


3, rushing fertilization: rushing fertilization is named according to usage, that is, a fertilization method that dissolves the fertilizer with water, so the compound fertilizer, amino acid fertilizer, humic acid fertilizer, and a large amount of water-soluble fertilizer on the market, There is also potassium fulvic acid, even bean noodles, milk, etc. can be used for flushing.

4, drip irrigation: drip irrigation requirements are higher than ordinary flushing fertilizer requirements, that is, the products that can be used to do drip irrigation are much less, must be water-soluble, do not block the small eyes above the drip irrigation belt Yes, commonly used for drip irrigation are urea, potassium dihydrogen phosphate, a large amount of elemental water-soluble fertilizer, amino acid-soluble fertilizer, and the like.

     Generally, a large number of elements of water-soluble fertilizer, containing amino acid water-soluble fertilizer, containing alginic acid water-soluble fertilizer, containing humic acid water-soluble fertilizer, trace element water-soluble fertilizer, potassium dihydrogen phosphate can be used for both foliar fertilizer and fertilization, and can also be used for drip irrigation. It is still possible to use a small amount of compound fertilizer for drip irrigation, but the water solubility is not very good. The long-term use will block the small holes, so it is generally not recommended, especially some imported drip irrigation facilities with higher cost.
