Introduction | calcium ammonium nitrate is a nitrogen fertilizer made by melting ammonium nitrate with a certain proportion of limestone and dolomite powder. The ingredients were NH4NO3 and a mixture of CaCO3, mgco3. Calcium ammonium nitrate nitrogen content of 21% ~ 26%(N), gray white or light yellow particles or powder, aqueous solution is weak alkaline. |
Chemical Fertilizer | calcium ammonium nitrate is currently the most soluble calcium-containing chemical fertilizer in the world, its high purity and 100% water solubility reflects the unique advantages of high quality calcium fertilizer and high efficiency nitrogen fertilizer. As a kind of high-quality calcium fertilizer with good physical and chemical properties, it has many advantages: (1) calcium nitrate calcium nitrate is the main component of calcium nitrate, the calcium content is very large, and the calcium content is all water-soluble calcium, plants can directly absorb the calcium, which can fundamentally change the crops due to calcium deficiency caused by plant dwarf, growing point atrophy, terminal bud dead, stop growth, young leaf curl, leaf edge Brown, root tip death, even decay, fruit top also appear depression, dark brown necrosis and other symptoms, improve plant resistance to disease, thereby improving product quality, increase economic benefits. (2) the absorption of nitrogen by plants is mainly in the form of nitrate, while the nitrogen in calcium ammonium nitrate is mostly in the form of nitrate, and without the need to transform in the soil can be quickly dissolved in water and directly absorbed by plants, which makes the nitrogen utilization of calcium ammonium nitrate higher, thereby promoting the crops of potassium, calcium, magnesium, zinc, absorption of iron and manganese, reduces various deficiency disorders. (3) calcium ammonium nitrate is basically a neutral fertilizer, which can improve the acidic soil. After the fertilizer is applied to the soil, the change of pH is very small, so it will not cause soil hardening, and can make the soil become loose, at the same time, it can reduce the concentration of active aluminum, reduce the fixation of aluminum to phosphorus, and provide water soluble calcium, which can improve the resistance of plants to diseases and promote the activity of beneficial microorganisms in soil. (4) granulation calcium ammonium nitrate effectively has the characteristics of difficult caking and high thermal stability, which is different from the unsafe factors of other products of the same type in the process of transportation, storage and sale, and can be used safely. |
physical and chemical properties | the physical properties of calcium ammonium nitrate are better than ammonium nitrate and safer. Because the finished product contains calcium carbonate, it has a good effect on acidic soil. If it is combined with phosphate fertilizer, it should not be mixed with water-soluble phosphate fertilizer to avoid reducing the effectiveness of phosphorus. |
Application | new high efficiency compound fertilizer, is a kind of high efficiency and environmental protection green fertilizer, widely used in greenhouse and large area farmland. |
efficacy and role | calcium ammonium nitrate, is a highly efficient and environmentally friendly green fertilizer. Soluble water, fertilizer effect is fast, has the characteristics of Rapid nitrogen supplement and direct calcium supplement. After application into the soil, the soil can become loose, which can improve the resistance of plants to diseases and promote the activity of beneficial microorganisms in the soil. In the cultivation of economic crops, flowers, fruits, vegetables and other crops, can extend the flowering period, promote the normal growth of the root stem and leaves, ensure the bright color of the fruit, increase the sugar content of the fruit, and achieve the effect of increasing production and income. 1. The product has good water solubility, rapid dissolution-easy absorption-no precipitation. 2. The product is rich in nitrate nitrogen, water-soluble calcium, contains nutrients without transformation, can be directly absorbed by crops, rapid onset, rapid use, the fertilizer utilization rate is about 2-3 times the ordinary fertilizer. 3. The prevention and correction of adverse physiological phenomena caused by calcium deficiency in crops is better. 4. It can be used in different growth stages of crops to promote the normal production and metabolism of roots, stems and leaves of crops. Especially in the crop fruit period and nitrogen deficiency, calcium is recommended to use, can promote fruit coloring, fruit swelling, spot color quickly, Peel bright, improve yield and quality. Application method in the dosage: This product can be used for machine, topdressing, flushing, spraying, drip irrigation and spraying, fruits and vegetables per mu 10kg-25kg; Field crops per mu 15kg-30kg. Drip irrigation and spraying recommended 800-1000 times water dilution after application. The specific application rate and application frequency should be determined according to different soil and different crop fertilization schemes. According to the actual growth and fertilizer demand of crops, it should be applied several times. |
Application | the effect of calcium ammonium nitrate on the fluidity, setting time, compressive strength, resistivity and internal temperature of sulphoaluminate cement paste, the effects of hydration heat, hydration products and pore structure on the early strength of calcium ammonium nitrate were analyzed. Calcium ammonium nitrate can significantly accelerate the hydration process of sulphoaluminate cement, so that its early strength is significantly improved, so it can be used as an early strength agent. |
