Abstract

The invention discloses agricultural ammonium polyphosphate capable of being chelated with medium trace elements. The agricultural ammonium polyphosphate is characterized by comprising the following components in parts by weight: 10000 parts of agricultural ammonium polyphosphate, 200-2000 parts of a trace element additive, 1-100 parts of a sulfur-containing agent, 1-50 parts of a precipitation inhibitor, 1-50 parts of an emulsifying agent, 1-20 parts of an acid and alkali regulating agent, 1-5 parts of an oxidant and 1-5 parts of an amino acid type nutrient. A water-soluble agricultural ammonium polyphosphate fertilizer is compounded so that ammonium polyphosphate and the additive which are originally incapable of being chelated with metal ions or are low in chelation quantity have the chelating capability; the prepared chelated type ammonium polyphosphate is moderate in acid-base property; the solution is stable and free of precipitates within three months; the suitable application temperature range is from -15 DEG C to 40 DEG C; the agricultural ammonium polyphosphate is convenient to popularize and use nationwide.

Description

technical field [0001] The invention relates to an agricultural ammonium polyphosphate with medium and trace element chelating ability, and also relates to a preparation method of the agricultural ammonium polyphosphate. Background technique [0002] Phosphorus is one of the three major nutrients of crops. Reasonable application of phosphorus fertilizer can increase the yield of fruit crops, increase the sugar content of sugar crops, and increase the oil content of oil crops. Traditional phosphate fertilizers are mostly applied once as a base fertilizer, and the utilization rate is low; the nutrient content of the fertilizer is single, which cannot meet the nutritional needs of the crops during the growth period, and the additional medium and trace element fertilizers are prone to precipitation reactions with the existing phosphate fertilizers, making the medium and trace elements inactive. It cannot satisfy the growth of crops with special preferences. [0003] In order to...
