Problems solved by technology

The fertilizer synergist can absorb free nitrogen in the air and soil, release it slowly and reduce evaporation and loss, but its pH value is 3-6, which is not conducive to use on cultivated land where soil acidification is caused by long-term use of chemical fertilizers; Furthermore, because chemical products such as water-absorbing resin and sodium humate are used as main raw materials, and there are many process links, the process is complicated, and the energy consumption is high, it will inevitably lead to high product costs and it is difficult to carry out market promotion.

Abstract

The invention discloses a manure synergistic agent, a preparation method, and applications thereof. The manure synergistic agent concretely comprises the components by weight proportion as follows: fly ashes are 10 to 65 parts, modifying agent is 5 to 15 parts, carriers are 20 to 75 parts, and dispersant is 10 to 65 parts; the manure synergistic agent is prepared and made through the hybrid modification reaction. By utilizing the agent, the fly ashes, which are industrial waste, are reused after being modified in synergic combination with the manure, thereby reducing the environmental pollution. The manure synergistic agent has the advantages of not only reducing the nitrogen loss, promoting the absorption and the utilization to activated silicon and trace elements on crops, but also improving the physicochemical characters of the acid soil.

Description

technical field [0001] The invention relates to a fertilizer synergist, in particular to a high-efficiency, low-cost modified fly ash fertilizer synergist and its preparation method and application. Background technique [0002] Our country has a lot of people and little land, and the application of chemical fertilizers is the most important means of increasing agricultural production. However, the use of chemical fertilizers in our country has been seriously wasted for a long time. The current average utilization rate of chemical fertilizers is less than 30%, which is far lower than the level of 60% in developed countries. The low utilization rate of chemical fertilizers not only increases the burden on farmers, but also directly leads to serious pollution and impoverishment of soil. The pollution of chemical fertilizers to soil also causes organic pollution of water bodies, eutrophication pollution, and even groundwater pollution and air pollution through farmland runoff. ...
