[ use ] diammonium hydrogen phosphate is one of the most widely used high phosphorus fertilizers, which is one of the most soluble fertilizers, the acidic soil is better, the phosphorus and nitrogen elements are the ideal fertilizer for nitrogen crops, can be directly applied to crop foliar spray, chongshi, drip irrigation, and replace urea; Industry for wood, paper, fabric flame retardant, fiber processing and dye industry dispersants, fire retardant coating, etc. [ production technology and advantages ] the high quality diammonium phosphate produced by 85 % phosphoric acid is adopted to ensure product quality at the source. High content of main products, fully ensure the proportion of main products in the products, total water soluble, low impurity content, the quality of downstream products is more perfect. [ packing ] usually 25 kg / bag, lined with plastic bag, outer woven bag, neutral package; Store in a well-ventilated dry place.
