1, the reaction when the fertilizer is mixed When a variety of fertilizers are used as a nutritive mother liquor, due to the presence of a variety of ions in the liquid, various reactions between the ions may occur, thereby affecting the effectiveness of nutrients. When formulating a nutrient solution for fertigation, the solubility of the product after mixing the different fertilizers must be taken into account. The fertilizer mixture reduces the solubility of the mixture due to the formation of precipitates. More than two storage tanks are used to store the fertilizers that will produce precipitation after mixing. 2. Temperature change when fertilizer dissolves Most fertilizers are accompanied by thermal reactions when dissolved. If the phosphoric acid dissolves, it releases heat, and when the urea dissolves, it absorbs heat and lowers the temperature of the water. Understanding these reactions has a certain guiding significance for the preparation of nutritional mother liquor in the field. 3, fertilizer and irrigation water reaction Irrigation water usually contains various ions and impurities. Such as calcium, magnesium, sulfate, carbonate and bicarbonate ions. When these ions in the irrigation water reach a certain concentration, they react with ions in the fertilizer and produce precipitates. The hardness of irrigation water in northern China is relatively high. The irrigation and fertilization is performed. The calcium and magnesium in the irrigation water are combined with phosphate ions and sulfate ions in the fertilizer to form a precipitate. When the hardness of water is high, fertilization (especially phosphate fertilizer) through the irrigation system can easily produce precipitation, causing clogging of the dripper and the filter. It is recommended to use acidic fertilizers. Regularly inject acid solution into the irrigation system to dissolve the sediment and prevent the dripper from blocking. Water hardness can usually be known by measuring the conductivity of irrigation water. When the conductivity of the irrigation water is high (greater than 2-3 dS/m), the risk of precipitation may be due to the application of phosphate or sulfate. At the same time, the addition of fertilizers (inorganic salts) to irrigation water with high conductivity may cause salt damage to crops. 4. Reaction between fertilizer and equipment for irrigation Because fertilizers are used through irrigation systems, the materials and fertilizers of the irrigation system must be in direct contact. Some materials are easily corroded, rusted or dissolved, and some are resistant to acids, alkalis, and salts.
Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues. Proteins perform a vast array of functions within living organisms, including DNA replication, catalyzing metabolic reactions, responding to stimuli, and transporting molecules from one location to another.
We supply protein, which is generally consumed immediately before and after exercising, or in place of a meal. Some types of protein are to be taken directly before and after a workout, while others are to be taken before going to bed. The theory behind this supplementation is that bodybuilders, by virtue of their unique training methods and end-goals, require higher-than-average quantities of protein to support maximal muscle growth.
