Fertilizer synergist and its preparation method and application

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. ...
