In order to prevent dripping plugs, good fertilizers such as urea and potassium dihydrogen phosphate should be used. When applying compound fertilizers, try to select completely special fertilizers for instant application. When it is really necessary to use fertilizers that cannot be completely dissolved, the fertilizer must be dissolved in pots or barrels and other containers. After the sedimentation, the upper solution is poured into the fertilizing tank to enter the drip irrigation system, and the remaining residue is applied to the soil.
Organic fertilizers and phosphorus fertilizers are generally used as base fertilizers. Because some of the phosphate fertilizer, such as superphosphate, is only partially dissolved, the residue tends to clog the spray head. Ammonia in ammonia is volatile, but also to change the acidity of the water, easy to cause precipitation of calcium and magnesium in the water.
Select fertilizers that are less corrosive to the irrigation system. Such as ammonium sulfate, ammonium nitrate corrosion of galvanized iron is serious, and almost no corrosion of stainless steel; phosphoric acid has mild corrosion of stainless steel; urea on aluminum, stainless steel, copper without corrosion, mild corrosion of galvanized iron.
Vitamins are organic compounds and vital nutrients that an organism requires in limited amounts. An organic chemical compound (or related set of compounds) is called a vitamin when the organism cannot synthesize the compound in sufficient quantities, and it must be obtained through the diet.
Your body needs them to work properly, so you grow and develop just like you should. They are essential for the normal growth and development of a multicellular organism. Once growth and development are completed, vitamins remain essential nutrients for the healthy maintenance of the cells, tissues, and organs that make up a multicellular organism; they also enable a multicellular life form to efficiently use chemical energy provided by food it eats, and to help process the proteins, carbohydrates, and fats required for respiration.
