Problems solved by technology

[0003] Diammonium phosphate is the main phosphate fertilizer variety in my country. It is a high-concentration nitrogen and phosphorus binary fertilizer, especially suitable for nitrogen and phosphorus-loving crops. However, the apparent utilization rate of phosphate fertilizer in my country is only 10%-20%. Low yield, easy to fix, difficult to absorb and utilize crops, etc.

Abstract

The invention discloses a phosphorus fertilizer synergist, synergistic diammonium phosphate containing the phosphorus fertilizer synergist, and a method for preparing the synergistic diammonium phosphate, wherein 100 parts by weight of the phosphorus fertilizer synergists comprise, by weight, 10-15 parts of humic acid, 5-15 parts of polyglutamic acid, 2-5 parts of carboxymethyl chitosan, 2.5-6 parts of the EDTA chelated trace elements, and 0.5-2 parts of the sodium methylene bis-naphthalene sulfonate. According to the invention, after the phosphorus fertilizer synergist is mixed with a phosphorus fertilizer, the fixation of the phosphorus fertilizer by soil can be remarkably reduced, the phosphorus activity is improved, crop root growth is promoted, and trace elements in the soil are activated and supplemented.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a phosphate fertilizer synergist, a synergistic diammonium phosphate containing the synergist and a method for preparing the synergistic diammonium phosphate. Background technique [0002] Phosphorus is an essential nutrient element for crop growth and development. Crops can only absorb available phosphorus in the soil, mainly including phosphate (PO 4 3- 、HPO 4 2- 、H 2 PO 4 - ) and the adsorbed phosphorus and organic phosphorus that can be released into the soil solution. However, the available phosphorus content in the soil is extremely low, which is far from meeting the phosphorus demand of crops. At present, the main way to supplement crop phosphorus is to apply phosphorus fertilizer, but the conversion rate of phosphorus fertilizer is extremely fast after it is directly applied to the soil, and the effectiveness gradually decreases with time, forming an...
