Humic acid synergistic ammonium phosphate and preparation method thereof

Abstract

The invention relates to a humic acid synergistic ammonium phosphate and a production method thereof. The fertilizer comprises the components in parts by weight as follows: 0.05-1.5 parts of a humic acid synergist and 98.5-99.95 parts of ammonium phosphate. The humic acid synergistic ammonium phosphate slows fixing of phosphorus in the soilin soil and increases the utilization rate of a phosphate fertilizer on the basis of nutrient releasing and utilization; the agricultural operation can be simplified on cultivation; the nutrient utilization rate can be increased (by 5-10%) on the benefit; nutrient loss can be reduced, secondary pollution is avoided, and the agriculture production cost is reduced; the humic acid synergistic ammonium phosphate has the characteristics that raw material sources are wide, transportation and application of the fertilizer are convenient, the mechanical operation is facilitated, and the like; and the addition technology is simple and the cost is low in the ammonium phosphate production, so that the humic acid synergistic ammonium phosphate has a wide application prospect in synergistic ammonium phosphate production and industrial promotion.

Description

【Technical field】 [0001] The invention belongs to the technical field of agricultural chemicals. More specifically, the present invention relates to a humic acid synergistic ammonium phosphate fertilizer, and also relates to a production method of the humic acid synergistic ammonium phosphate fertilizer. 【Background technique】 [0002] Ammonium phosphate is an important phosphate fertilizer variety in my country. It can be used as base fertilizer and topdressing fertilizer for wheat, cotton, vegetables and other crops in agricultural production. Ammonium phosphate is an important raw material for the production of compound fertilizer and BB fertilizer. The most prominent problem in the application of phosphorus fertilizers in agricultural production is that the phosphorus applied to the soil will be quickly fixed by the soil, and will be converted into insoluble Ca-P compounds in the northern calcareous soil, and converted into Fe with poor availability in the southern red s...

Problems solved by technology

The most prominent problem in the application of phosphorus fertilizers in agricultural production is that the phosphorus applied to the soil will be quickly fixed by the soil, and will be converted into insoluble Ca-P compounds in the northern calcareous soil, and converted into Fe with poor availability in the southern red soil. -P compound and Al-P compound

At present, there are still many controversies in the academic circles about the modification of ammonium phosphate. Some people advocate slow-release method modification (such as coated ammonium phosphate). , 2007,22(5):64~67), but some people think that slow-release phosphorus fertilizer may lead to rapid fixation of phosphorus in the soil, reducing its fertilizer efficiency

However, it is not disputed that the modification and synergistic approach to ammonium phosphate is fundamentally to slow down the fixation of phosphorus in the soil
