Nutritional characteristics of rice For every 500kg of rice produced, the absorption of nitrogen, phosphorus, and potassium is N: 7.5-9.55kg, P2O5: 4.05-5.10kg, K2O: 9.15-19.1kg, and the ratio of nitrogen, phosphorus, and potassium is 2:1:2- 4. Rice has a large amount of silicon, which produces 500kg of rice and absorbs 87.5-100kg of silicon. Therefore, in high-yielding cultivation, rice straw should be returned to the field and straw compost or silicic acid fertilizer should be applied to meet the needs of rice for silicon. Fertilization Law of Rice Absorption of nutrient elements in the rice growth stage varies with the growth process. Generally, the absorption at the seedling stage is small. With the progress of fertility, the vegetative body gradually grows in large quantities, and the amount of sucking fertilizer also increases correspondingly, reaches the highest value before heading, and then gradually decreases as the root activity decreases. The absorption of nitrogen was the highest in the tillering period, up to 50%, followed by the panicle development period, but there was a difference between the varieties; the absorption of phosphorus was the highest in the panicle development period, accounting for about 50%, followed by the tillering period, and the fertility. Maturity still absorbs a considerable amount of phosphorus; absorption of potassium is most abundant before heading, and little after heading. The uptake of rice has a tendency to increase with the increase of the amount of fertilizer, and the amount of distribution in different parts of the rice plant body varies. If the amount of inhalation is large and the distribution is unreasonable, the output is not necessarily high. The normal growth of rice also requires elemental fierce, boron, zinc, molybdenum, copper, etc. It should also pay attention to supply. Clear Sterile Vials are primarily used for mixing different medications or solutions for injection or research applications like HCG, heparin, lidocaine, diabetic medications and morphine for intravenous or syringe injections. Some drugs may need to be diluted or mixed with sterile water or other drugs. Sterile Vials are also used for nuclear medicine, PET-CT, Liquid collection. Clear sterile vials are also used for nuclear medicine, PET-CT, Liquid collection.Clear sterile vials are produced by aluminum caps, non-latex butyl stoppers and clear SCHOTT Neutral Type I glass vials. They are approved by cGMP and FDA with internally sterile.The production process is carried out under strict Class 100 workshop. Finished vials can meet the FDA`s authorised 14-day sterility test.
