Ratio:17-17-17 / Content: Nitrate nitrogen≥ 7% / Packing: 25kg,40kg, 50kg / Color: white / more detail: Water-soluble potassium dihydrogen phosphate, high-tower nitro.Natural gas chemical industry, high tower nitrothio, improve the quality of fruits and vegetables, specially added polyglutamic acid, does not contain biuretIndependent nitro raw materials, multi-stage compounding, precise batching, molten homogeneous slurry, natural gas chemical industry, tower granulation, mesoporous anti-counterfeiting, balanced nutrients. Nitrate nitrogen is high, fast melting, fast effect, activate the soil, promote absorption, and the quality is synchronized with the world and manufacture world-class nitro fertilizer.1.The use of natural gas chemical industry, tower granulation, more balanced nutrition. 2.Nitrate nitrogen content is high, melting block, fast absorption. 3.The utilization rate of nitrogen fertilizer has been greatly improved, and the fertilizer effect has been effective in three days, and the increase in production and income has been significant.1. Nutritionally complete, multi-formula, can be used when crops are not growing. Quickly disperse to crop roots, balance crop root nutrients, quickly promote the growth and development of crop stems and leaves, and raise seedlings and strong trees. 2.Ammonium polyphosphate is used as raw material to increase the activity of phosphate fertilizer and prevent the fixation of phosphate fertilizer. 3.Efficient nitrogen and potassium nutrition, promote the absorption of calcium and magnesium ions in the soil, and grow robustly. 4.Efficient nitrogen and potassium nutrition promote rapid fruit expansion and coloration.It is widely used in greenhouse crops, flowers, fruit trees, vegetables, tobacco and other cash crops, as well as wheat, corn and other field crops, especially suitable for dryland crop application.
